Interactions among Biobehavioral, Social and Environmental Influences on Obesity: Implications for Population-level Interventions
Chair: Neil Schneiderman, PhD

Biobehavioral Issues in Pediatric Obesity
Alan Delamater, PhD
This presentation will review the latest findings regarding the prevalence and etiology of pediatric obesity. Research addressing the efficacy of behavioral interventions for the treatment and prevention of pediatric obesity will be reviewed. Clinical challenges and future research issues will be highlighted.

Modification of Hyperinsulinemia in the Treatment of Obesity: Southbeach Pharmacotherapy
Richard Surwit, PhD
This presentation will review the animal and experimental studies of the pharmacologic reduction of hyperinsulinemia in the treatment of obesity. Potential mechanisms by which reduction of hyperinsulinemia will be discussed as well as implications of this work for dietary approaches to obesity.

Childhood Obesity: Rates, Risks, and Remedies in the Hispanic Community
Amelie Ramirez, DrPH and Kipling J. Gallion, MS
Childhood obesity can presage an adulthood of cardiovascular disease, diabetes, cancer, and other obesity-related diseases, but in Hispanics, whose income, education, and insured rates are among the lowest and selected obesity rates are some of the highest, the prospects are especially daunting. Hispanics' status as the fastest growing ethnic group in America compounds the implications. Genetic, cultural, environmental, socioeconomic, and behavioral threads combine to create a distinct experience of obesity and overweight. Under nutrition, vitamin deficiencies, and food insecurity threaten the health and undermine the future of the youngest. Much more research and an expansion of the corps of scientists performing Hispanic health research must be undertaken.

Can Environmental Dietary factors Make Regulating Energy Intake Difficult?
Hollie A. Raynor, PhD
Basic eating research has consistently demonstrated that two environmental dietary factors, variety and amount of food, increase consumption. The effect of these two variables does not appear to be greatly influenced by participant characteristics, such as age, gender, or weight status, suggesting that these environmental dietary variables strongly influence eating behavior. Interestingly, as the prevalence of obesity has increased over the past several decades in the U.S., data from U.S. food manufacturers indicate that portion sizes of foods and the number of different foods available in the market have also greatly increased during this time. These findings suggest that given the current environment, to help individuals achieve energy balance, or to reach a negative energy balance necessary for weight loss, these two dietary factors need to be addressed. Preliminary data from 8-week behavioral weight loss interventions indicate that directly targeting reducing amount of food via single-serving, portion-controlled foods or decreasing variety via a dietary prescription that limits the number of different energy-dense snack food may both be helpful in reducing intake of targeted foods as compared to a standard, hypo caloric, low-fat diet prescription.

Children's Cognition and Achievement: Associations with Obesity and Effects of Exercise
Catherine Davis, PhD *
The presentation will review the literature on the association of children's cognition & achievement with obesity and inactivity. Experimental data testing the effect of an exercise intervention on these outcomes with be presented, and implications for educational policy will be highlighted.
