New data published in JAMA today finds that there has been no significant change in rates of overweight/obesity overall for children between age 2 to 19 years of age since 2003. This is unfortunate news in the big fight against overweight and obesity. Conclusions from the study, “Obesity prevalence remains high and thus it is important to continue surveillance.” Obesity rates remain high at with 17% of children and more than 1/3 of adults.
The good news is that there was improvement in one small group, toddlers age 2 to 5. Numbers from National Health and Nutrition Examination Survey(NHANES) show reductions in overweight and obesity for the preschoolers by as much as 43% during the last decade. Really hoping this is a canary in a coal mine situation — perhaps they’re chirping a clue. Learning the “why” behind the reduction in obesity for preschoolers feels like a huge opportunity. However for the mass of people researched in total (over 9,000 from birth to age > 60 years) the data confirms we’re not done tipping the scales.
The research article evaluated rates of overweight and obesity between 2003-04 NHANES data and 2011-12 data on children and adults. The CDC is highlighting the success in the toddlers, stating:
While the precise reasons for the decline in obesity among 2 to 5 year olds are not clear, many child care centers have started to improve their nutrition and physical activity standards over the past few years. In addition, CDC data show decreases in consumption of sugar-sweetened beverages among youth in recent years. Another possible factor might be the improvement in breastfeeding rates in the United States, which is beneficial to staving off obesity in breastfed children.
It’s wonderful to see signs of improvement in the small population of children included in the NHANES data but this research article doesn’t investigate how the improvements were made and/if they are stable. More research will have to unfold. We’re all desperate — parents, pediatricians, public health experts — for solutions that work in not only curbing, but reversing the rates of overweight and obesity. This data can potentially focus the light on where we need to look to study cause and effect to determine possible success stories and strategies. Five quick tips for parents now: Read full post »
