The State University of New York at Buffalo (SUNY-Buffalo), Department of Pediatrics, and the U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS), Grand Forks Human Nutrition Research Center (USDA-ARS-GFHNRC), Healthy Body Weight Research Unit, located in Grand Forks, North Dakota, will conduct research addressing the roles of non-shared environments on body weights of adolescent siblings discordant in that respect. This will involve studying the energy balance behaviors of discordant siblings and putative risk factors contributing to sibling differences in energy balance behaviors and adiposity. Risk factors to be studied include differential sibling responsiveness to eating paradigms that test sensitivity to external eating cues and internal satiety cues, and social influences on eating and activity that occur within and outside the family. The study will involve 24 same-sex pairs of boys and girls, 13-17 years of age and discordant for adiposity. This research will extend understanding of behavioral contributors to body weight in adolescents and mechanisms of adolescent obesity. It will also provide important information on how some remain normal weight in obesigenic environments.
