Failure of anti-obesity legislation

August 21st, 2012

Christopher Still and I have a new article out, “Survey of antiobesity legislation: are these laws working?” Unfortunately, the answer is no. This finding is consistent with a paper earlier this year by Dr. Jeffrey Mechanick and last year’s Cochrane Review but contrary to the somewhat rose-tainted view of the Institute of Medicine’s recent report. Here is the abstract:

Obesity is well recognized as a major public health crisis throughout the USA. In recent years,governmental bodies at the federal, state and local levels have enacted policies intended to preventthe transition to obesity. Researchers have had the opportunity to study these policies and evaluate theirimpact on prevention of obesity.

Recent findings Most public policies have been directed principally, but not exclusively, to the prevention of obesity inschool-age children. Interventions have been directed to encouraging breast-feeding, to changing school lunches, limiting access to sugar-sweetened beverages, encouraging physical activity, changing thecomposition of competitive foods and affecting food advertising directed at children as well as collectingBMI information. Efforts more directed at adults include encouraging workplace wellness programs andimproving the nutrition label on packaged foods with front-of-package labels and caloric information on restaurant menus.

Summary  For the most part, evaluations of the interventions reveal weak or modest benefits. The actual picture mightbe less positive due to the poor quality of research and publication bias. Push back by industry and otherswill require higher quality experimental and real world studies. All interventions fail to accommodate themultifactorial aspects of obesity.

Competitive Food Sales in Schools Not Affect Obesity

February 2nd, 2012

Most US middle and high schools sell soft drinks, candy and chips to their students. These practices have been widely criticized as contributing to childhood and adolescent obesity. However, a new study followed  approximately 19,450 children from fifth to eight grade. Researchers found the children’s weight gain was not associated with the introduction or the duration of exposure to competitive foods. This did not vary by gender, race/ethnicity or family socioeconomic status. Possible explanations are that children’s food preferences and dietary patterns are firmly established before adolescence. Also, schools are highly structured whereas home life may have more opportunities for snacking. http://www.asanet.org/images/journals/docs/pdf/soe/Jan12SOEFeature.pdf.
