To keep kids from getting fat, use smaller plates and portions, limit TV viewing and make sure they get 10 hours of sleep a night

Kentucky ranks high in child obesity. Parents can make sure their children maintain a healthy weight with three simple suggestions highlighted in recent studies: Serve them meals on smaller, child-size plates, pay attention to what they watch on TV, and make sure they get enough sleep.

In Kentucky, almost 18 percent of middle-school-age children and 16 percent of elementary-age kids are obese, and every third child born who was in the U.S. in 2000 will develop Type 2 diabetes if current trends continue, says a recent report from the University of Kentucky's College of Public Health.

The three suggestions are based on three new studies in the April issue of Pediatrics.

One study found first-graders served themselves larger food portions and consumed almost 50 percent of the extra calories they put on their plates when using adult-sized dinner plates instead of child-sized salad plates, reports Michelle Healy of USA Today.
A second study examined the relationship between heavy use of media  and increased body mass index,  a measure based on height and weight that can classify someone as being overweight or obese. It found that TV usage is the most problematic and leads to higher BMI scores, reports Healy. One reason for this may be that TV advertising includes commercials for unhealthy snack foods. Or, perhaps kids are missing out on exercise because they watch so much TV. 

A new sleep study adds to research saying that insufficient sleep may contribute to the rise in adolescent obesity because it changes hormone levels that could lead to overeating and weight gain, reports Healy.

These findings support existing recommendations to help children attain and keep a healthy weight according the UK report. Portion sizes should be a third of adult portions for younger children and two-thirds of adult portions for older children; children's TV screen time should be limited to two hours per day; and children should get 10 hours of sleep each night.

White children exposed to high levels of chemical BPA are five times more likely to be obese, study concludes

White children exposed to high levels of bisphenol A, better known as BPA, are five times more likely to be obese than children with low levels, according to a study published last week in the Journal of the American Medical Association. The study by the New York University School of Medicine is the first to link the chemical to obesity in children, which is especially prevalent in Kentucky.

Environment Health News reporter Brien Bienkowski reports that scientists found traces of BPA, which are used in some canned food and beverages, paper receipts and dental sealants, "are found in virtually every U.S. adult and child. In the study of body mass and BPA data from 2,838 youths aged 6 to 19, only white children were found to have significant increases in obesity prevalence as their BPA levels increased. Those with the highest concentrations in their urine were five times more likely to be obese than children with the lowest levels. Black children with higher BPA levels were 1.25 times more likely to be obese than those with lower levels, which the scientists said is not statistically significant. Hispanic children had the same rates of obesity at the highest and lowest levels."

Bienkowski reports that "representatives from the chemical industry said the study had too many weaknesses to prove any connection. Steven Hentges, from the American Chemistry Council's Polycarbonate/BPA Global Group, said that attempts 'to link our national obesity problem to minute exposures to chemicals found in common, everyday products are a distraction from the real efforts underway to address this important national health issue.' "

One study of preschoolers in North Carolina and Ohio found that 99 percent of BPA exposure was through food. But since the chemical is in many plastics and other products, this is difficult for scientists to pin down. “People are always told if you just stop eating or exercise more, you will lose weight. But there may be more to it … and I think there is,” said Retha Newbold, a visiting scientist at the National Institute of Environmental Health Sciences, who specializes in BPA and other endocrine-disrupting chemicals.  (Read more)
