U.S. obesity rates remain high despite encouraging signs seen in young children
The prevalence of obesity remained high in the United State,
with about one-third of adults and 17 per cent of children and teens obese in
the 2011-2012 period, alongside encouraging development monitored among two- to
five-year-olds, a new survey released has showed.
Researchers from the U.S. Centres for Disease Control and
Prevention, examined trends for childhood and adult obesity among 9, 120
persons with measured weights and heights in a 2011 to 2012 nationally
representative study known as National Health and Nutrition Examination Survey.
Overall, the study, published in the Journal of the American
Medical Association, indicated that there had been no significant changes in
obesity prevalence among two- to 19-year-olds or adults in the U.S.between 2003
to 2004 and 2011 to 2012 periods.
For youth aged two to 19 in the U.S., 16.9 per cent were
obese and among adults, 34.9 per cent were obese, it said.
Though overall obesity rates remained unchanged, rates in
young children did improve. The prevalence of obesity among children two to
five years of age decreased from 14 per cent in 2003 to 2004 period to just
over 8 per cent in 2011 to 2012 period, a decline of 43 per cent, the
researchers said.
"We continue to see signs that, for some children in
this country, the scales are tipping. This report comes on the heels of
previous CDC data that found a significant decline in obesity prevalence among
low-income children aged 2 to 4 years participating in federal nutrition
programmes."
The CDC Director Tom Frieden said in a statement. "This
confirms that at least for kids, we can turn the tide and begin to reverse the
obesity epidemic."
While the precise reasons for the decline in obesity among
two- to five-year-olds are not clear, many child care centres have started to
improve their nutrition and physical activity standards over the past few
years, the CDC said.
In addition, CDC data showed decreases in consumption of
sugar- sweetened beverages among youth in recent years. Another possible factor
might be the improvement in breastfeeding rates in the U.S., which is
beneficial to staving off obesity in breastfed children, it said.
"I am thrilled at the progress we've made over the last
few years in obesity rates among our youngest Americans," U.S. First Lady
Michelle Obama said at the CDC statement.
"With the participation of kids, parents, and
communities in Let's Move! these last four years, healthier habits are
beginning to become the new norm."
