Abstract/OtherAbstract:
|
The vast majority of American middle schools and high schools sell what is known as "competitive foods", such as soft drinks, candy bars, and chips, to children. The relationship between consumption of sugar-sweetened drinks and snacks and childhood obesity is well established but it remains unknown whether competitive food sales in schools are related to unhealthy weight gain among children. We examined this association using data from the Early Childhood Longitudinal Study Kindergarten Cohort. Employing fixed effects models and a natural experimental approach, we found that children's weight gain between 5(th) and 8(th) grades was not associated with the introduction or the duration of exposure to competitive food sales in middle school. Also, the relationship between competitive foods and weight gain did not vary significantly by gender, race/ethnicity, or family SES, and remained weak and insignificant across several alternative model specifications. One possible explanation is that children's food preferences and dietary patterns are firmly established before adolescence. Also, middle school environments may dampen the effects of competitive food sales because they so highly structure children's time and eating opportunities. |
