CDC: 1 In 5 US Children May Have Mental Disorder

This is just definitional extravagance.  One in three adults were once said to be neurotic as well.  You can define your way to any conclusion you want

 Nearly 1 in 5 children in the U.S. suffers from a mental disorder, and this number has been rising for more than a decade.

According to a study conducted by the Centers for Disease Control and Prevention, up to 20 percent of American children are suffering from mental disorders such as attention-deficit hyperactivity disorder (ADHD), anxiety, depression and autism.

The CDC's first study of mental disorders among children aged 3 to 17 also found that the cost of medical bills for treatment of such disorders is up to $247 billion each year.

"This is a deliberate effort by CDC to show mental health is a health issue. As with any health concern, the more attention we give to it, the better. It's parents becoming aware of the facts and talking to a health-care provider about how their child is learning, behaving and playing with other kids," said Dr. Ruth Perou, the study's lead author.

The CDC data was collected between 1994 and 2011, and it shows that the number of children being diagnosed with mental disorders has been steadily growing. The study did not conclude exactly why the numbers are increasing.

More research is needed to determine the specific causes of mental disorders, said Dr. Perou, and that greater awareness could lead to an uptick in diagnoses. A host of environmental factors, including chemical exposure and poverty, also can affect a child's mental health, she said.

The study also found that girls were more prone to depression and alcohol abuse than boys, and that 6.8 percent of U.S. children are affected by attention-deficit hyperactivity disorder.


Live longer with a daily dose of calcium: Women who take a supplement have a 22% lower risk of death

All this probably shows is that people who take supplements are more careful with their health generally

Taking a calcium supplement of up to 1,000 mg per day can help women live longer, say researchers.

A new study shows a 22 per cent lower risk of dying over a 10-year period compared with women who are not taking supplements regularly.

The study is likely to reassure many who take supplements either prescribed by their doctor for osteoporosis - thinning bones - or bought over the counter as 'bone insurance'.

Previously there have been fears that high-dose supplements could raise the risk of dying from heart disease.

But Canadian researchers behind the latest study are unequivocal in recommending extra calcium for women with low intakes.

Lead author David Goltzman, of McGill University in Montreal, said 'Our study found daily use of calcium supplements was associated with a lower risk of death among women.

'The benefit was seen for women who took doses of up to 1,000 mg per day, regardless of whether the supplement contained vitamin D.' according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

The researchers analysed data from the large-scale Canadian Multicentre Osteoporosis Study which monitored the health of 9,033 Canadians between 1995 and 2007. During that period, 1,160 participants died.

The findings show a 22 per cent cut in risk of death for women using calcium supplements compared with non-users, but no statistical benefit for men.

The study found no conclusive evidence that taking vitamin D had an impact on death rates.

There appeared to be no benefit from taking calcium at doses bigger than 1,000mg a day.

Dr Golzman said 'Higher amounts of calcium were potentially linked to longer lifespans in women, regardless of the source of the calcium.  'That is, the same benefits were seen when the calcium came from dairy foods, non-dairy foods or supplements.

'Our recommendation would be to assess dietary intake to meet calcium and vitamin D requirements for bone health and to consider supplementation as necessary to meet the requirements.'

The study, which is to be published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism, suggests several possible mechanisms for promoting longer life.

Calcium supplements are linked to a better balance of blood fats, lower risk of high blood pressure, better bone metabolism and bowel health.

Health benefits may also be driven by eating more calcium from food within a healthy diet, including dairy products and fish.

There have been conflicting results from studies in recent years about the benefits and possible harms of taking calcium supplements, especially more than 1,000mg a day.

Scientists believe mega doses of calcium circulating in the blood have a 'flooding effect' which may lead to hardening of the arteries and heart attacks.

In contrast, dietary calcium is taken in small amounts spread throughout the day, so is absorbed slowly.

The Food Standards Agency recommends adults have 700mg of calcium a day, which should come from dietary sources including all types of milk, cheese, yoghurts and green, leafy vegetables.

Official figures suggest women consume only 740mg of calcium per day from food sources on average - 43mg lower than in 2000-1.

Carrie Ruxton, spokesperson for the Health Supplements Information Service, said it was likely that women taking extra calcium were reaping the benefits of having an optimal supply of the mineral.

She said: 'Men tend to get a bigger intake from their diet but many women don't consume as much, especially those cutting back on dairy products.

'The benefits found in this study could be from women having extra supplies, bringing them up to normal and optimal levels.'

She said there were subtle effects on metabolism apart from calcium's bone-building qualities, including regulation of appetite and weight.

But the direct effects of helping to prevent the consequences of osteoporosis such as falls and hip fractures should not be under-estimated.
