5,000 people contracted HIV/AIDS in Kogi

 

 OVER 5,000 youths are said to have been allegedly infected with the deadly HIV/AIDS virus in Kogi State within the last one year. This was disclosed during the capacity training organised for over 1,000 barbing and hairdressing salon operators in the Kogi Central senatorial district.

 A research recently carried out by a lecturer at the Federal College of Education, Okene, Titus Olusegun Stephen, in conjuction with Tertiary Education Trust Fund (TETFund), indicated that the spread of the deadly disease was alarming, especially among students of tertiary institutions, barbers and hair dressers in Kogi. 

 The research also revealed that when a random sampling of the affected group was carried out, some students barbers and salon operators, who are living with the virus, did not know they had contracted the disease. 

 According to Mr Stephens, a fellow of French Research Institute in Africa, the first segment of the training in the state was organised for the barbers and hair dressers, to curb the spread of the deadly disease in the state. “Sadly, our findings revealed that only about five percent of the people realise the need to sterilise their tools before usage,” he said, while promising that similar training would be carried out for students in the state.

Why young girls are getting fatter


Many young girls only get 17 minutes of exercise a day, research suggests. Boys fare little better, with the average eight to ten year old active for only 24 minutes a day. The figures – which fall well short of the hour of daily exercise recommended – have been described by campaigners as unbelievable. 

 Girls only got an average of 17 minutes of exercise a day And they will fuel concerns about the future health of a ‘couch potato’ generation which prefers playing computer games to football. Newcastle University researchers fitted 508 schoolchildren aged between eight and ten with monitors that recorded how active – or inactive – they were during their waking hours. 

The results revealed how little time the children, from Gateshead, Tyne and Wear, spent doing moderate or vigorous activities such as running, skipping or dancing. Overall, only 4 per cent of their time was spent being this physically active – equivalent to around 20 minutes. But this was an average figure for both sexes and girls were much less active than boys. 

The researchers, who believe the picture to be the same nationwide, said children must get into the habit of exercising from a young age if Britain’s obesity time-bomb is to be defused. In need of role models? Olympic athletes like Jessica Ennis could change children's attitudes to sport Lead researcher Dr Mark Pearce said: ‘Given the importance of physical activity in maintaining good health, we know we need to get our kids more active.

 ‘What we hadn’t known until now is how young we need to be catching them.’ He said it was worrying that even by the age of eight girls were less active than boys. Previous studies have found that many girls lose interest in sport by their teens but it was not known just how early this lack of enthusiasm set in. Dr Pearce said possible solutions include encouraging young girls to see female athletes as role models and offering a wider range of sports in schools, such as dance. 

The study, published in the journal PLoS ONE, also found the children of older fathers tended to be less active. This could be due to older fathers having more senior posts at work and so putting in longer hours, leaving them less time to play with their children. They may also have different attitudes to parenting or generally be less active. 

Surprisingly, the study found that children whose parents restricted their TV viewing exercised less than those allowed to watch as much as they wanted. Dr Pearce said it is possible that seeing sport on TV encourages youngsters to participate themselves, or the finding could simply be due to chance.

A drink a day for pregnant women 'will NOT harm unborn baby's development'



Drinking alcohol while trying to conceive or in early pregnancy – even the occasional binge – will not harm the baby’s development, research has claimed. It also shows moderate drinking, around one a day, does not affect the child’s IQ and other brain functions. 

However, high levels of consumption – nine or more drinks a week – were linked to a lower attention span at the age of five. 

The findings contradict official guidance, which says alcohol is best avoided in pregnancy and when trying to conceive. 

Previous research has suggested the odd tipple does not affect intellectual or behavioural development, but this is the first significant evidence that occasional binge drinking in the early weeks of pregnancy is unlikely to irrevocably harm the baby.

 Danish doctors behind the research said the findings should not be taken as a green light for pregnant women to binge drink, defined as having five or more drinks on one occasion. 

Joint author Professor Ulrik Kesmodel, of Aarhus University Hospital, said it was clear that heavy, continuous drinking was detrimental to the unborn child. Heavy drinking in pregnancy is linked to Foetal Alcohol Spectrum Disorder in children, which can cause physical, mental and behavioural problems.

 Newly pregnant women were often concerned their baby had been conceived at a time when they may have been binge drinking, said Prof Kesmodel.

Smartphone users are expose to health risk


It says people have become "screen slaves" and are often working while commuting or after they get home. The society said poor posture in these environments could lead to back and neck pain. Unions said people needed to learn to switch off their devices. An online survey, of 2,010 office workers by the Society found that nearly two-thirds of those questioned continued working outside office hours. 

 The organisation said people were topping up their working day with more than two hours of extra screentime, on average, every day. The data suggested that having too much work and easing pressure during the day were the two main reasons for the extra workload. 

 'Posture' Continue reading the main story “ Start Quote Individuals who find themselves unable to leave their work in the office should talk to their managers and learn to switch off their smartphones” Brendan Barber Trades Union Congress The chairwoman of the Chartered Society of Physiotherapy, Dr Helena Johnson, said the findings were of "huge concern". 

She said: "While doing a bit of extra work at home may seem like a good short-term fix, if it becomes a regular part of your evening routine then it can lead to problems such as back and neck pain, as well as stress-related illness. "This is especially the case if you're using hand-held devices and not thinking about your posture. 

Talk to your employer if you are feeling under pressure." The general secretary of the Trades Union Congress, Brendan Barber, said: "Excessive work levels are not good for anyone. Overworked employees are not only unlikely to be performing well at work, the stress an unmanageable workload causes is also likely to be making them ill.

 "By the time someone is so overloaded they constantly feel the need to put in extra hours every night of the week at home, things have clearly got out of hand. "Individuals who find themselves unable to leave their work in the office should talk to their managers and learn to switch off their smartphones."

Why are so many women starting the menopause before 40?



When Amanda Warne’s periods stopped at the age of 21, doctors put it down to stress and over-training following an intensive diet and exercise regimen. For the next four years she suffered terrifying mood swings and depression and paid countless visits to her GP and a specialist — while a series of blood tests revealed see-sawing hormone levels. Finally, doctors concluded the sporty student had suffered a premature menopause. 

 Blood tests showed her levels of key hormones were such that she had been through the menopause — and it wasn’t clear why. ‘I couldn’t believe it,’ says Amanda. ‘I was studying at the London College of Fashion and was with my first boyfriend, the love of my life, who was desperate for children.

 ‘He told me bluntly he knew he wouldn’t be able to stay with me for ever because his desire for children would always outgrow the love he had for me. 'I became an insecure wreck and felt worthless.’ She also found herself crippled with mood swings, depression, panic attacks and bouts of exhaustion — classic menopausal symptoms. ‘Some days I could barely crawl out of bed. I felt as though I was going mad.

 'I knew something had really changed in my body, but no one seemed to listen,’ says Amanda, now 33 and a businesswoman living in North London. Taking Hormone Replacement Therapy (HRT) improved her quality of life, but Amanda still suffers exhaustion, low libido, headaches and a tingling sensation in her head. She finds the latter particularly worrying following the publication of alarming new research last week by U.S. 

doctors who discovered that women who go through a premature menopause are also more likely to suffer a potentially fatal brain haemorrhage, a cerebral aneurysm. This occurs when part of the artery weakens and swells. The artery can then burst and cause a stroke or death, with half of those suffering a cerebral aneurysm likely to die. And the younger a woman is when she becomes menopausal, the greater the chances of a cerebral aneurysm — Amanda went through the menopause 30 years before the average age of 51. 

‘I do realise I may be facing a shortened life expectancy,’ she says. The new U.S. research is part of a growing body of evidence pointing to the staggering toll on a woman’s overall health associated with early menopause — a concern because more women are being diagnosed with the disorder. 

Most scientists define a premature menopause, or premature ovarian failure (POF), as occurring when a woman’s ovaries stop working before the age of 40, though some studies include women up to the age of 45. As well as cerebral aneurysm, they are also at greater risk of heart disease — they are 50 per cent more likely to die and 80 per cent more likely to suffer from heart disease than women who go through the menopause between the ages of 52 to 55. 

 A study last year by Imperial College London found that women who had early menopause were also twice as likely to have a poor quality of life in health terms. Another study, by the Mayo Clinic in the U.S., found that affected women had a greater risk of dying early, developing heart disease, neurological disorders, including Parkinson’s and Alzheimer’s, psychiatric disorders and osteoporosis.

 Women were particularly likely to die early or develop heart disease if they’d not been taking HRT following their early menopause, said the researchers. ‘These recent studies are telling us what we have suspected for some time, but until now no one has done the work to quantify it,’ says Dr Kevin Harrington, a consultant gynaecologist at the Bupa Cromwell Hospital in London.

Study: Abstaining from alcohol significantly shortens life



A newly released study shows that regular drinkers are less likely to die prematurely than people who have never indulged in alcohol. You read that right:Time reports that abstaining from alcohol altogether can lead to a shorter life than consistent, moderate drinking.

Surprised? The tightly controlled study, which looked at individuals between ages 55 and 65, spanned a 20-year period and accounted for variables ranging from socioeconomic status to level of physical activity. Led by psychologist Charles Holahan of the University of Texas at Austin, it found that mortality rates were highest for those who had never had a sip, lower for heavy drinkers, and lowest for moderate drinkers who enjoyed one to three drinks per day.

Of the 1,824 study participants, only 41 percent of the moderate drinkers died prematurely compared to a whopping 69 percent of the nondrinkers. Meanwhile, the heavy drinkers fared better than those who abstained, with a 60 percent mortality rate. Despite the increased risks for cirrhosis and several types of cancer, not to mention dependency, accidents and poor judgment associated with heavy drinking, those who imbibe are less likely to die than people who stay dry.

A possible explanation for this is that alcohol can be a great social lubricant, and strong social networks are essential for maintaining mental and physical health. Nondrinkers have been shown to demonstrate greater signs of depression than their carousing counterparts, and in addition to the potential heart health and circulation benefits of moderate drinking (especially red wine), it also increases sociability.

While it’s always important to drink responsibly, this is one study that warrants raising a glass.

Why common anti-hypertensive herb takes toll on liver, kidney


Individuals taking an anti-hypertensive herb, Bryophyllum pinnatum, may be at risk of kidney and liver damage, researchers have warned. In a review of the benefit of using Bryophyllum pinnatum in the treatment of hypertension, researchers stated that although, the extract decreased blood pressure, thus supporting the claim of people who use it for this purpose; it has toxic effect on the kidney, heart and liver.


 The plant, Bryophyllum pinnatum (Crassulaceae) is accepted as an herbal remedy in some parts of the world. It is commonly known as air plant, miracle leaf, life plant etc. Among the Igbos of Nigeria, it is known as ‘odaa opue’, in Yoruba as ‘ewe abamoda’ or ‘odundun’. Among the Igbos, B. pinnatum is believed to have anti-hypertensive activity. Decoction of the leaf is usually taken to lower the blood pressure. 


Some people also chew the raw leaves of the plant for this purpose. In the study, which lasted for four weeks, the effects of aqueous leaf extract of Bryophyllum pinnatum on the blood pressure of anaesthetised cats, as well as on the liver and kidney status of the rabbit were investigated. Twenty-four adult healthy rabbits of both sexes weighing between 1.2 and 2.4 kilogrammes were used for this study. 


They were divided into three sex matched groups of eight animals each and maintained at room temperature. The animals in the first and second groups received 150 mg and 300 mg/kg body weight of the water extract of B. Pinnatum respectively, while those in the third group served as the control and were fed orally with the feed and water only. The plant extract was administered intraperitoneally after it was reconstituted in distilled water. 


 The results revealed that, the extract produced a small decrease in the blood pressure of the anaesthetised cat and also reduced the effect of adrenaline-induced elevation of blood pressure. During this investigation, it was observed that all the animals administered with the higher dose of 300 mg/kg body weight of B. pinnatum aqueous extract died after the fourth day of initiating treatment.


 It was also noticed that only one rabbit showed signs of dullness, while the rest were generally asymptomatic and fed normally until they were found suddenly dead. The fall in the blood pressure of the cat, produced by the aqueous extract of B. pinnatum leaf was found to be dose dependent, but not very marked. 


For every dose of the extract given, the reduction in the blood pressure, produced by the extract was found to be more pronounced with increasing dose. The hypotensive effect was, however, very transient and always returned to its original level within three minutes. The researchers stated: “The current results of the four-week study showed that the aqueous extract of the leaf of B.


 pinnatum, given intraperitoneally to rabbits in daily doses of 150 and 300 mg/kg body weight produced some biochemical and pathological changes in the animals.” They wrote: “Although, the extract decreased blood pressure supporting the claim of people that use it for that purpose, the findings here would not encourage the use of B. pinnatum for the management of hypertension. “The anti-hypertensive effect produced would not be of any real benefit considering that the fall in blood pressure was always diminutive. 


One must be wary of ingesting the extract of this herb because of its potential not only to be hepatotoxic (toxic to liver) and nephrotoxic (toxic to kidney) but, at high doses, also cardiotoxic (toxic to heart).” Previously, it has been reported that Bryophyllum species are highly toxic to stock. For instance, poisoned cattle showed signs of dullness, loss of appetite and weight. 


Also in Australia and Southern Africa, various Bryophyllum species have killed cattle as a result of their its toxic effect on muscles of the heart, The researchers attributed the sudden deaths of the rabbits to the same conditions noted in the case of the poisoned cattle, that is, disruption in the regular beat of the heart caused by the high dose of the aqueous extract of B. 


pinnatum (300 mg/kg) administered. Meanwhile Bryophyllum pinnatum is accepted as an herbal remedy in some parts of the world. Many of the Bryophyllum’s traditional uses in the treatment of conditions like rheumatoid arthritis, tummy bug, injuries from falls, numbness of limbs, bruise, burns and ulcer have been validated by animal studies and clinical investigations undertaken so far on the plant have been confirmed by the clinical research on the plant.


 Its traditional use for infectious conditions (both internally and externally) is supported by research indicating that Bryophyllum leaves have anti-bacterial, anti-viral and anti-fungal activity. The leaf and its juice have demonstrated significant anti-bacterial activity towards Staphylococcus, Escherichia coli, Shigella, Bacillus, Pseudomonas and multi-drug resistant bacteria strains. A water extract of Bryophyllum leaves administered topically and internally has been shown to prevent and treat Leishmaniasis. Similarly the traditional uses of Bryophyllum for upper respiratory conditions and coughs have been validated by studies demonstrating that the leaf juice has potent anti-histamine and anti-allergic activities. 


 In a study with rats and guinea pigs, the leaf juice was able to protect against chemically induced anaphylactic reactions and death by selectively blocking histamine receptors in the lungs. On the other hand, previous laboratory study established the pharmacological basis for the use of Bryophyllum in stomach ulcer; a leaf extract protected mice from ulcer inducers such as stress, aspirin and ethanol.

Ginger may help enhance memory


Ginger isn’t just a spice! In addition to ginger’s already-known health-boosting properties such as reducing motion sickness and nausea, having a soothing effect on the digestive tract and being a common remedy for colds, ginger can also help to support memory and cognitive function in middle-aged women. 


 Recent studies on how nature’s foods and natural medicines found in plants can help to improve memory and boost cognitive ability found herbs such as ginger to be a potentiating agent for cognitive functions. 

 Due to the increase in the middle-aged population, an abundance of research has focused on the development of cognitive enhancers from medicinal plants reputed for anti-oxidant and cognitive enhancing effects. According to Arabian folklore, ginger has been claimed to improve memory. Moreover, it has also been traditionally used as an ingredient for cognitive enhancement. Researchers considered 60 healthy women who received either a placebo or a ginger standardised extract of 400 milligramme or 800 milligramme daily for two months. 

The women were between 50 and 60 of age and reside in Thailand. The women’s cognitive function and memory at the beginning of the study and again after one and two months of supplementation was assessed. In the study, published in 2012 issue of the Evidence-Based Complementary and Alternative Medicine, the subjects receiving the ginger supplement reported a significant improvement in cognitive functions and an enhanced working memory compared to the placebo group. 

 This was after they excluded other conditions that could produce the disturbance of cognitive function such as any history of cardiovascular disease, respiratory disease, neuropsychological disease, head injury, diabetes, cancer, alcohol addiction, and anyone who smoked more than 10 cigarettes per day. 

Individuals taking prescribed, non-prescribed drugs, or nutraceutical compounds known to influence the function of the nervous system were excluded. They found that daily ginger intake, especially at higher amount, led to improvements in four key brain functions: power of attention, accuracy of attention, speed of memory, and quality of memory. 

 The researchers concluded that, “ginger extract enhances both attention and cognitive processing capabilities of healthy, middle-aged women, with no side effects reported. Our data revealed that ginger extract is a potential brain tonic to enhance cognitive function for middle-aged women.” 

 Although more research is needed to fully comprehend the mechanism behind this effect, the researchers suggested that the cognitive enhancing effect of this plant extract on working memory observed in this study might be partly related to its antioxidant effect. However, the researchers stated that the precise underlying mechanism and possible active ingredient responsible for the cognitive enhancing effect of ginger still require further investigation. 

 Although the side effect of ginger extract is rare, they hinted of the possibility of some minor adverse effects at higher doses such as gastro-intestinal disturbance, sleepiness, restlessness, sedation, and heartburn. Moreover, the researchers stated that the use of ginger in enhancing memory and improve cognitive function should be performed with caution because of the possibility of the extract also possibly interacting with medications. 

 These medications include anaesthesia, anticoagulants, and analgesics leading to arrhythmias, poor wound healing, bleeding, photosensitivity reaction, and prolonged sedation. The main active constituents found in ginger are gingerols and shogaols. Gingerols and shogaols are extracted from the rhizome of ginger and are known to exert antioxidant, anti-inflammatory, and anti-tumour activities A human’s ability to remember data, to reason, and understand things properly can start to worsen at age 45. 

 Identifying cognitive decline onset is crucial for effective medical interventions. The earlier cognitive deterioration can be spotted; the better medical treatments tend to be. Robust evidence showing cognitive decline before the age of 60 has important ramifications because it demonstrates the importance of promoting healthy lifestyles, particularly cardiovascular health, as there is emerging evidence that what is good for the heart is also good for the brain. Nonetheless, hormonal changes and stress are two of the main factors influencing cognitive functions in middle-aged women.

 Cognitive difficulties include memory loss and mild cognitive impairment, two factors frequently related to Alzheimer’s disease and dementia. But oxidative stress plays a very important role on stress-induced cognitive impairment, something that apparently can be reduced by certain plants as ginger. Meanwhile, ginger in Chinese medicine is used to treat a number of conditions, including congestion to cancer treatment and prevention. 

Individuals suffering from thyroid problems may find that the compounds in ginger, including zinc, magnesium and potassium, along with the root’s powerful anti-inflammatory properties have a positive effect on thyroid function. The Whole Foods Encyclopaedia indicated that ginger contains magnesium, which has been shown to be critical to controlling thyroid disease. Magnesium helps with muscle relaxation and prevents the development of an irregular heartbeat. Ginger can be used in different ways. Peeled and diced fresh ginger root can be added to soups and dishes. The root can also be steeped in hot water or added to tea. Ginger in its powder form can be used in baked foodss and roasted foods such as Suya and Kunu drink.

A Parent's Guide to Bedwetting


Parents share secrets and strategies with each other about how to deal with fussy eaters, colicky infants, and tantrum throwers. But bedwetters? The problem of bedwetting is still shrouded in embarrassment, despite the fact that it's very common.

 As a matter of fact, one in five 5-year-olds is a bedwetter, according to the American Academy of Pediatrics. To help you understand why, here are answers to some of parents' most frequently asked questions about bedwetting.

 Q: Why is my child bedwetting? 

 What you need to know before answering this is: Has your child consistently wet -- that is, never had dry nights -- or has your child been dry, and the bedwetting is a recent problem? Those are two very different situations. Most of the time, the child was never dry, a problem known as primary bedwetting (or by the medical term, primary enuresis). A much smaller number of children have what is called “secondary” bedwetting or enuresis.

 In this case, the child was dry for a long time, maybe a year, and then becomes a bedwetter. That is more unusual, and there is more likely to be a medical cause or a trigger, such as psychological stress or trauma. But that's true in less than 10% of cases. Most of the time, a child has primary bedwetting, and after a thorough physical examination and examination of the urine, no medical reason is found. In that case, the cause is rarely figured out. But one in five kids at age 5 has this. How abnormal can that be?

 Q: What causes a child to be a bedwetter? 

 Bedwetting of the primary type does seem to run in families. So whatever the cause is, it is likely that children who are bedwetters have some sort of genetic reason. It's also possible one or both of their parents wet the bed. The most popular theory is that bedwetters have a slight delay in maturation of their nervous system. When the bladder is full, the sleeping brain has to send a message down to the bladder not to pee. 

If your child's nervous system is a bit underdeveloped, the message might not get through. Another theory is that children who are bedwetters are very deep sleepers. They are sleeping so soundly their brains don't tell their bladder to hold it. Some experts also think that bedwetters may simply make more urine at night than other kids, and their bladder can't hold it all. Others hypothesize that their bladders have a smaller capacity to hold in the urine compared with kids who stay dry.

 Q: What should be done about bedwetting? 

 The first step is to talk about it with your pediatrician, which many parents don't do because they (or their child) are embarrassed. But it's crucial to do so because the first step in assessing a bedwetter is to rule out any medical causes.


A urine test could reveal a urinary tract infection or excess sugar in the urine as a cause. A physical examination might demonstrate constipation, for instance, which could push on the bladder and cause the bladder to release urine at inappropriate times. A sleep history may reveal that a child has a sleep disorder called sleep apnea, in which breathing stops for a brief time. Urine can escape during those episodes. Sometimes, secondary bedwetting can occur if a child is psychologically stressed or if he has lived through a disaster recently, such as a hurricane or fire. Those children may need some counseling or other help. Most of the time, however, your child will naturally outgrow bedwetting as he gets older. To help your child outgrow bedwetting, you can try a number of behavioral strategies outlined below.

 Q: At what age should we do something about bedwetting? 

 If you and your entire family is OK with it, you don't necessarily have to do anything. Except wash the sheets, of course, and perhaps have your child wear disposable underwear. About 15% of bedwetters get better, or outgrow it, every year without any treatment. By age 18, only 1% to 2% still wet the bed.

 But if you, or more importantly, your child, is so upset by this that it is disrupting your family, then talk about treatments with your pediatrician. The best time to do this is when your child says he wants to deal with it. When the child gets sick of it, says he feels like a baby, or is embarrassed because he can't go to friends' houses for sleepovers, this is a good time to talk to your doctor about remedies. 

 Q: What bedwetting product or treatment works best? 

 There aren't a lot of great studies comparing treatments. But it's pretty clear that what works best are the urinary alarms. In a published review, researchers compared bed alarms with behavioral interventions and medications. They concluded that bed alarms are the most effective.

 Many models of alarms are available, but all include a moisture sensor that you put in your child’s underpants that sounds an alarm when it detects urine. Once the alarms train the sleeping brain to inhibit the bladder contractions -- and prevent the urine from being released -- most kids stay dry. 

Better still, they remain dry even after the alarm is discontinued. The downside of alarms? They take a while to work -- usually months. They require participation by the parents, who may have to get up with their child and take him to the bathroom when the alarm goes off. It requires a lot of commitment. Another strategy is to wake your child two or three hours after he has gone to bed, and perhaps right before you go to bed, and have him pee. It has some effectiveness. You might also have your child wear disposable underwear until he or she outgrows bedwetting. 

 Limiting fluids after dinner might also have some benefit. But if your kid is really thirsty, it's not worth it. Some parents work with the child during the day to help him hold in the urine longer. They may set an egg timer when the child says he has to go and ask him to hold it for another few minutes, starting with five minutes and working up to 45 minutes or so. The theory is it will increase bladder capacity.

 Medications are another option. One medication is desmopressin, which reduces the amount of urine produced at night. However, medications only work when they are taken. Once the medication is stopped, the bedwetting comes back. Although medications have side effects, often they can be used on a short-term basis, such as when your child wants to go on a sleepover. 

 Q: What else can I do for my bedwetting child?

 You can reassure your child that he will eventually grow out of it. No matter how frustrated you are, don't punish your child for bedwetting. Try to normalize the experience for the child; sit down and talk to them. Letting them know they are not the only child with this problem seems to make them feel better, or at least less humiliated.

Overweight Kids May Do Worse in Mathematics : Study


Youngsters who are persistently overweight may not perform as well academically -- specifically in math -- as their normal-weight peers, new research suggests. Although the study didn't find a direct cause-and-effect relationship between being overweight or obese and school performance, the researchers did find that children who started kindergarten carrying extra weight and were still heavy when they finished fifth grade performed worse on math tests.

 "These children are not necessarily less smart, but they're performing less well," said the study's lead author, Sara Gable, an associate professor and state extension specialist in nutrition and exercise physiology at the University of Missouri, in Columbia. Gable said she suspects interpersonal troubles and internalizing behaviors may be why weight can affect math performance. 

 "We know, in general, that children who have poor peer relationships don't do as well at school," she said. "And we also know that children with internalizing behaviors don't do as well. Internalizing behaviors are anxiety, worry, not feeling as if they have a lot of friends and feeling sad. Children with weight problems tend to feel internalizing behaviors and not have good interpersonal skills," she added. 

 Gable said that these effects, year over year, are likely cumulative. Nancy Copperman, director of public health initiatives at North Shore-LIJ Health System in Great Neck, N.Y., said the study demonstrates the importance of preventing childhood obesity. "Obesity isn't just a cosmetic problem," she said. "It has impacts that go from chronic disease to mental achievement, and ultimately to income and a happy, successful, well-adjusted life." Results of the study appear in the July/August issue of the journal Child Development.

 For the study, Gable and her colleagues used data from the Early Childhood Longitudinal study. The current study included 6,250 youngsters from kindergarten through fifth grade. Weight and height were measured at five points throughout the study, and the measurements were used to calculate the children's body-mass index, a figure that assesses whether someone is normal weight, overweight or underweight. 

 The children were placed into one of three groups based on their weight: never overweight (80 percent of the children), persistently overweight (12 percent) or later-onset overweight (8 percent). The later-onset group was not overweight in kindergarten or first grade, but was overweight in third or fifth grade (or both).

Why sharing a bed is good for the heart (even if your other half snores!)


Snoring, sweating, stealing the sheets . . . it’s little wonder that an estimated one in four couples insist on sleeping in separate rooms. Now, however, there’s an emerging body of research to suggest there could be health benefits to sharing a bed with a long-term partner. It’s even been suggested as a major reason why people in close relationships tend to be in better health and live longer.

 Researchers from the University of Pittsburgh in the U.S. believe sleeping next to someone helps lower the stress hormone cortisol, perhaps because it encourages feelings of safety and security. Prolonged periods of elevated cortisol have been linked with an increase in cytokines — proteins involved in inflammation that can trigger heart disease, depression and auto-immune disorders.

 Sleeping together has a protective effect by lowering the levels of these proteins. ‘Sleep is a critically important health behaviour that we know is associated with heart disease and psychiatric wellbeing,’ says lead researcher Wendy Troxel, assistant professor of psychiatry and psychology at the university. ‘There is extensive literature showing that married people — happily married people, in particular — live longer, happier, and healthier lives than their unmarried or unhappily married counterparts.

 ‘We also know sleep is critically important for health and wellbeing, and it happens to be a behaviour couples engage in together, so it stands to reason it may be an important link with their health.’ Sharing a bed is also thought to boost levels of the ‘love hormone’ oxytocin, known to induce bonding feelings.

 This is traditionally thought to be released during sex, but Dr David Hamilton, a scientist who has examined the role of oxytocin in health in his book, Why Kindness Is Good For You, says it’s also associated with cuddling in bed and ‘pillow talk’. ‘Sleeping together will increase oxytocin levels, providing you are happy in the relationship,’ he says.

 ‘Making love is one of the most reliable ways to produce oxytocin, as is going to sleep embracing someone or just being physically happy in their company or with the conversation you are having in bed. ‘And oxytocin has a super-spiral effect; the more physical contact you have, the more oxytocin you’ll produce, which causes you to want more contact, and so on . . . Oxytocin can have an addictive effect.’  

Recent studies have shown oxytocin’s vital role in health. Scientists at Malmo University Hospital in Sweden found it can affect digestion. Those with lower levels had poorer gastric motility — the process by which food is moved from the stomach to the intestines, therefore slowing down digestion. Levels of the hormone have been found to be lower in patients with irritable bowel syndrome, says Dr Hamilton.

 ‘Oxytocin has also been shown to reduce inflammation. While inflammation is a necessary part of the healing process, too much of it, which can accompany bacterial infections or chronic stress, is damaging to the body. ‘It’s well known, for example, that inflammation plays a role in many types of cancer. ‘Meanwhile, a number of recent studies have shown how oxytocin can affect the heart.’

 For example, a study from the University of North Carolina asked 59 women who were married or had partners to keep a diary of the number of hugs they received over a set time. The scientists then analysed levels of oxytocin in the blood. The women who’d received the most hugs had the highest levels of oxytocin — and the lowest blood pressure and heart rates. ‘Indeed, oxytocin is like a natural angina medication,’ says Dr Hamilton. ‘Angina medication is basically nitric oxide, which expand blood vessels. Oxytocin helps the body produce nitric oxide itself.’ It may come as a surprise to the long-suffering partners of snorers, teeth grinders and kickers, but sharing a bed may also improve your sleep. In another of Dr Troxel’s studies, published in 2009, women in long-term stable relationships fell asleep more quickly and woke up less frequently during the night than single women or women who lost or gained a partner during the six to eight years of the study.

Girl, 1, can only eat fish fingers as mystery illness means anything else could kill her

This is the one-year-old girl who can only eat fish fingers - because her mystery illness means almost anything else could kill her. Imogen Elliott, from Coventry, is severely allergic to grass, pollen, animal fur, polyester, plastic, cosmetics, chemicals and even sunlight. 

Almost any food can trigger a life-threatening reaction, so the 20-month-old child's mother Kirsty sustains the sensitive girl on an unchanging diet of gluten-free fish fingers. Doctors believe the problem is down to an underlying condition - but as yet they have no idea what that could be. Until Imogen's illness is diagnosed, her mother Kirsty has to be constantly on the alert for a potentially fatal reaction. If Imogen eats or comes into contact with something she is allergic to, her skin erupts in painful, itchy sores and she is often violently sick. Last year, the toddler's family gave her some tuna - which she had always been able to eat before. The youngster immediately went into anaphylactic shock, her throat swelling up and cutting off her oxygen supply.

 Her terrified mother rushed her to hospital, where doctors were fortunately able to save her life. Had she got there any later, Imogen might not be alive today. Mrs Elliott, 30, said: 'It was a really scary day. I could have lost her. 'Some children can build up tolerance to foods but the more exposure Imogen has, the worse her reactions get. 'I always keep fish fingers in the freezer. She loves fish fingers.

 'Her diet does worry me. I have to give her multi-vitamins and calcium supplements.' As a baby, Imogen struggled to keep her milk down and her distraught mother was even accused of making her daughter sick. It was only as she got older that doctors realised the extent of her allergies. 

Mrs Elliott and husband Mark, 35, have now spent all their savings on buying an uncontaminated new house and spent three months researching before they bought any furniture. They have also invested around £5,000 in special allergy-free carpets and even grass. Unlike other toddlers, Imogen cannot go to nursery, because it would be too dangerous, and she will have to be home-schooled when she is older.

Plane brain: Flying really can give you a headache

Traveling from A to B is a headache for many people, whether it's by train, plane or automobile. But the pain is apparently rather more acute when travelling by air for some, researchers have said. They argue that 'airplane headache,' a form of pain that flares up during landing, should get more recognition in the medical world. 

 The head pain, which can be characterised by its severity and position on one side of the head and near the eye, was first reported in medical literature in 2004, with several dozen more cases documented in the following years. Now, Italian researchers are suggesting that the ailment should be considered a new subtype of headache, putting forward a list of criteria doctors can use to diagnose it. 

 Lead researcher Federico Mainardi, of Giovanni e Paolo Hospital in Venice, called it 'a recently described headache disorder that appears exclusively in relation to airplane flights, in particular during the landing phase.' A group of 75 people with symptoms suggestive of airplane headache fitted the features of past cases - severe pain on one side of the head that was usually limited to the time the plane was landing. The pain was almost always short-lived, at less than 30 minutes for 96 per cent of the people. 'Is (airplane headache) a unique disorder? I think it is. 

But others might disagree,' said R. Allan Purdy, a neurologist and professor at Dalhousie Medical School in Halifax, Canada, who wrote an editorial on the report. 'Nobody knows what causes it. Nobody knows how many people have it. Nobody knows what treatments work,' he added, but noted that classifying it as a distinct disorder would allow it to be studied more directly.

The backlash against breastfeeding

On the cover of Time magazine, there's a three-year-old standing on a stool, breastfeeding. A combination of his height, and maybe the stool, means that he looks about seven. Three is not that old, in the world of "extended" breastfeeding, but seven is giving it some by anybody's standards. The mother, Jamie Lynne Grumet, said, "I understand some of the breastfeeding advocates are actually upset about this," which is most probably true. 

There's a tipping point, in the world of breastfeeding advocates: they are evangelical to the point of dogmatism about the desirability of breastfeeding an under-two, go a bit quiet between two and three, then back right off, on the tacit understanding that extended breastfeeders make them all look weird.

 I'm guessing here, but I think the anxiety is that once the child looks like a proper little person, with proper teeth and enzymes, you enter a world of confusion about who needs what from whom; the kid doesn't need the milk, clearly. At this point it is pure attachment, pure love. Who needs it expressed this way, the mother or the child? I personally don't care.

 But if I were really invested in breast milk as liquid gold, I can see that I wouldn't want that to be the question people were asking. I could not have loved breastfeeding more if I'd been brainwashed; I experienced it as a kind of hallucinogenic experience. A bit like taking an E. But I also had the strong suspicion that the claims made for its benefits – the higher IQ, the protection against obesity, the superior bonding, the warding off of disease both now and for ever, both for baby and for mother – were mostly bogus.

 A lot of the reasoning seemed syllogistic (babies born into low-income families end up fatter; low-income mothers breastfeed less than high-income mothers; therefore breastfeeding prevents obesity) or frankly lame. I knew a lot of mothers who formula fed; they didn't seem to love their babies less.

 When I wrote a book about pregnancy, I included some of this lameness, while underlining the fact that, speaking for myself, I didn't care whether or not the health benefits were real, I'd do it again even if it made the baby's IQ go down. Two months later, I was on my way to chair a discussion for the Royal College of Midwives when I got a call from one of their press officers: she said there might be a demonstration against me outside the venue. "What do you mean?" "Oh, nothing huge – there were just some people who argued against you being there, and they might… demonstrate."

 "Are they going to egg me?" "You're obviously a really sensitive person," she said. "I'm not sensitive," I countered, although if I'm honest I did not relish the idea. "It will just affect what I'm going to wear." Nobody demonstrated against me that night, but someone did approach me in the meeting saying they'd appreciate a retraction for the paperback. "Retract what?" I asked. Just retract. Stop saying what you're saying, because breastfeeding really is better. 

 A year later, a conference on infant feeding included the American academic Joan B Wolf, who conducts a rigorous, close-range examination of the science behind pro-breastfeeding advice in Is Breast Best? She concludes that the case for breast milk is hyperbolic. "The majority of studies have demonstrated that there's a relationship between breastfeeding and better health. But whether this relationship is causal has never been established." The only discernible benefit was in reducing instances of gastroenteritis, thanks to a specific agent found only in human milk, secretory immunoglobulin A (or SIgA). Again, there was the threat of a demonstration against her, this time outside the British Library, which would have been a bit embarrassing (you can't demonstrate against someone collating study results. What are you going to put on your placard? Down with Meta-Studies?). But again, it didn't happen.

 This struck me as a bizarre place to have arrived at; where even to talk about the evidence behind the benefits of one type of infant feeding over another is heretical. The questioning of the orthodoxy is taken as a direct attack on babies. And who would attack a baby? Only a vile lunatic; so the temperature of the debate is often quite high from the start. Charlotte Faircloth, a sociologist who did her PhD on "full-term" breastfeeding in London and Paris (I think of her as the George Orwell of lactation), comments mildly: "I think, weirdly, not being a mum was really a useful thing for me while I was doing my research, because I wasn't a them or an us. It allowed me to ask some basic questions that I wouldn't have been able to otherwise. Everything has got very heated, and very moralised. How you feed your kids is no longer a personal decision.

 There's this idea that you can breastfeed your way out of poverty, or if you don't breastfeed your kid's going to be fat or have a low IQ…" She pauses. "It's all got a bit out of hand." In some ways, with the distance afforded by now having two fully weaned children, I understand it: the act of breastfeeding – that is, sitting in Starbucks half-naked – is taken to be such a transgression of social norms that in order to make women feel OK about it, there has to be a degree of overstatement as to how beneficial it all is. But there are some women daring to challenge the idea that breast is best. Repudiating "attachment" parenting, French feminist Elisabeth Badinter argues that breastfeeding – along with natural labour, co-sleeping and giving up work – all amount to an ideal of motherhood that effectively subjugates a woman's professional, sexual, spousal, adult identity.

 "If 24 hours a day the woman is reduced to her role as a nursing animal, even putting the child in the bed between the father and the mother, the father is completely put aside," she said recently, "This is very hard for men, and I think the child becomes a factor in the separation of the couple. Breastfeeding a few weeks, sometimes a few months, OK. But when it's recommended that you breastfeed your child for one year – six months exclusively, with nothing else, day and night, on demand – there are obviously consequences for a couple." Badinter's beef with the idea of "total motherhood" has caused more of a furore in the US than it did in France, where her main opponents were Greens (she laid some of the blame for this essentialist maternal model at the door of "ecologists" with their non-disposable nappies).

 In the US, where arguably women have been in thrall to this idea of perfect motherhood (or "Borg-parenting", as the New York Times put it) for longer, the idea that motherhood and feminism might be at odds has been greeted in some predictable and some comically unexpected ways. A number of commentators have said that, in fact, the right to breastfeed was a victory for feminism, in wresting the care of their babies from a professional, medicalised elite. Others have conceded that the struggle for perfection and unanimity in any direction – towards breastfeeding or away from it – is necessarily bad for women, removing their personal agency. (Which Bandinter doesn't argue with: "Let women do what they want!" she says. "There are women for whom breastfeeding is a true pleasure.

 It's very good for them and it's very good for the baby. But to breastfeed a baby if the mother herself doesn't like it? It's a catastrophe. The decision to breastfeed is an intimate and private decision. No one should be able to interfere.") But there are certainly those, for instance LaShaun Williams, who argue that Badinter is right – motherhood is at odds with feminism, and this is a good thing, since when we finally accept the primacy of the maternal role, it shows up feminism for the sham it is. "We should question," she writes, "why so many of us are working – single and married women alike. Is it because we bought the feminist lie that we don't need a husband? Is it because we want to prove to the world that we are worth something? Or is it to live in a ritzy neighbourhood and drive an Audi Q7? When we bring children into this world we also agree to sacrifice parts of ourselves."

 In this version of events, just by wanting financial agency, women have succumbed to avarice, and a feminist lie – which makes Badinter's point for her, that the "essential mother" shtick is a way to crowbar women out of the marketplace. "Career-driven mothers" should be reminded, says Williams, "that family comes first." But of course, feminist theorising on its own would be no match for the superiority of breastfeeding, if it were all it was cracked up to be. In government literature, both here and in the US, the benefits of breastfeeding are expressed uncritically, and to the farthest reaches of what's physically possible. 

The NHS Start4Life advice says that breastfeeding will give babies a smaller chance of, "developing eczema; getting ear, chest and tummy bugs and have [sic] to go to hospital as a result; being fussy about new foods; being constipated; being obese and developing diabetes when they are older. There are advantages for mums who breastfeed too: breastfeeding lowers the risk of breast and ovarian cancer; breastfeeding naturally uses up about 500 extra calories a day so mums who breastfeed often find it easier to lose their pregnancy weight." Now, only one of those claims is without dispute, as Wolf concluded, the one about "tummy bugs". The research about ear infections, respiratory disease and diabetes is very mixed. Neither fussiness around new foods nor constipation are classic or very salient markers of good health. The obesity studies are debatable. 

The weight loss of breastfeeding mothers is taken from a WHO report, based on two interventionist studies in Honduras. It's nothing like that straightforward: it does use 500 calories a day, but if your appetite increases at the same time, it is amazing how quickly and easily you can pop 500 calories into your mouth. Meanwhile, Wolf points out, no study on maternal cancer has "distinguished the effects of breastfeeding from the behaviour of women who breastfeed". And that's the rub, as she writes: "Breastfeeding cannot be distinguished from the decision to breastfeed, which could represent a more comprehensive commitment to healthy living." It's a self-selecting sample, a phrase that is a foreign language in the world of early-years intervention. 

 The interesting thing is, as Wolf told me, these problems aren't in dispute: "The American Academy of Paediatrics released a statement on breastfeeding, with a point in the policy document where they say, 'There are a lot of methodological problems'. And then they continue as if those problems didn't exist. It's like saying something with your fingers behind your back – you can carry on with your business as though those problems weren't there." Wolf also quotes Diane Eyer, a psychologist and academic, in this observation that has consequences right across the early years debate: "The notion of risk [has been] transformed from a dichotomy to a continuum."

 It's no longer a case of "safe" versus "dangerous"; rather, everything carries some risk and you announce your fitness as a parent to the world by interpreting hazards in the most credulous, fervent way. The onus isn't on the researcher to prove the point any more – the onus is on the parent, or parent-to-be, to prove that they'll believe the researcher. This leads to some utterly bogus propositions being taken as fact (don't get me started on stress in pregnancy). At the same time, at the level of policy, there is a zealous belief in the importance of the first three years in fashioning good citizens, which you can see in everything from David Cameron's parenting classes to Frank Field's idea for a school in which the pupils are enrolled in utero (I'm not kidding). 

The assumption tends to be that the kind of people who breastfeed anyway and eat organic have no need of advice, while the people to whom advice is dispensed are essentially counselled to act more like the middle classes. And it makes sense on its own terms, since if you've decided that social mobility will be achieved by intervening at the parental level with the under-threes, you have basically decided this: if only everybody would parent (there's really no other verb for it) the way the richest parent, then everybody would have the same chances as currently only the richest enjoy. One precept this relies on is an amplified belief in the risks of certain types of parenting over other types; the minute you accept the idea of different but equal – formula feeding, say, as different from breastfeeding, but fine all the same – you abnegate your right as a government to stick your oar in. 

 Leaving social policy and returning to the world, it is interesting to note that the standard advice is to breastfeed exclusively ("don't rush to mush!") for six months, and yet only half of mothers in the UK who start breastfeeding (an impressive 91%) continue past six weeks. So there's this very trenchant public health message that the majority of people aren't taking any notice of – in that regard, it's a bit like the five-a-day message in adult nutrition (ie, we mainly ignore it), and yet it's unlike the proscription of drink-driving, which has pretty good social penetration. The message I take from that is that we tend to supplement government advice with the evidence of our own five senses, and only when the two are in accord do we take it all that seriously.

 I didn't set out to write a controversial book about pregnancy. (Within the sappy remit of thinking your kids are the best thing that ever happened to the world, how controversial is it going to get, realistically?) And yet there are wells and eddies of the baby world that reflect things about class and gender and authority and control that are not entirely babyish.

Time breastfeeding cover ignites debate around 'attachment parenting'

With a photo that was engineered to ignite a storm of online heat and noise, Time magazine's cover depicts a 26-year-old-mother breastfeeding her three-year-old son, who stands on a chair.


 The story is meant to explore the growing trend of "attachment parenting", preached primarily by Dr Bill Sears, co-author of the Baby Book, which encourages mothers to breastfeed into toddlerhood, co-sleep, and "wear" their babies in an effort to limit their time away from their child. But few people read beyond the cover language (Are You Mom Enough?) on Thursday, when the photo was posted online. Actress Alyssa Milano, herself a new mother, echoed many complaints when she tweeted to her 2 million followers:


"I looked at this and my first thought was, it's a really cheap shot. It's a piece about Bill Sears – it's not about an attractive blonde woman breastfeeding," Financial Times columnist Gillian Tett told Time magazine executive editor Rick Stengel on Morning Joe Thursday. Breastfeeding, which is both natural and encouraged for women who are physically able, has become taboo in some corners of American society. 

 Women have been booted from coffee shops and Target stores. Barbara Walters famously complained when the mother she was seated next to on a flight began to breastfeed. "There are people who tell me they're going to call social services on me or that it's child molestation," Grumet tells Time in her interview. 

"People have to realize this is biologically normal. It's not socially normal. The more people see it, the more it'll become normal in our culture." On her blog, which appears to have been crushed by new traffic, causing the servers to crash, Grumet posted a photo of her mother breastfeeding her as a child. 

She writes that having the photo on display in her home – for all to see – imbued her with the belief that breastfeeding is natural and nothing to be ashamed of. Indeed, the World Health Organization recommends exclusive breastfeeding to age six months and then continued breastfeeding to age two or older. Still, fewer than 15% of babies are breastfed through age six months in the US, according to the Centers for Disease Control. So the question remains: does the photo do more harm than good in the worthy cause to get more able mothers to breastfeed? Or is it a fair representation of what attachment parenting is all about?

 It's apparently been a boon for Grumet, who has been tweeting from New York and will be making the rounds on breakfast TV to preach the attachment-parenting gospel. "It's certainly an arresting image. It's an image to get people's attention about a serious subject," Time's Stengel told the Washington Post. "Judging by the reaction on Twitter this morning. some people think it's great, and some people are revolted by it. That's what you want. You want people talking."
