Socila determinants have been identified as a fundamental cause of health and disease in most industrialized countries. However much less is known about which characteristics of communities may lead to disparities in health outcomes. Collective efficacy the willingness of community members to look out for each other and intervene when trouble arises, is a social factor shown to be associated with outcomes related to obesity, including rpemature mortality associated with individual measures of body mass index (BMI) in adolescents. We use a multi level, ross sectional survey in los angeles country involving 807 adolescents in 684 households in 65 neighborhoods in addition to a sample of 3000 adult respondents. The main outcomes measures are BMI, at risk of overweight and overweight status. Using a two level model, we find significant relationships between collective efficacy and all three outcomes, net of levels of neighbourhood disadvantage. The associations between BMI and collextice efficacy could potentially be explained by several factors, including a metabolic pathway, neighborhood differences in the physical and social environments, or a combination of these two. If group level collective efficacy is indeed important in the regulation of individual level net energy balance, it suggests that future interventions to control weight by addressing the social environment at the community level may be promising.
