Individuals living in socioeconomically disadvantaged neighborhoods have disproportionately high rates of obesity and obesity-related morbidity, including increased risk for physical role limitations and cardiovascular diseases (CVD). Studies of potential mechanisms linking neighborhood disadvantage with health outcomes have primarily focused on daytime health behaviors, including diet or physical activity. However, sleep is a critical health behavior that is associated with neighborhood disadvantage, and may play a causal role in explaining the links between neighborhood disadvantage and health. However, the extant research on neighborhood disadvantage and sleep is based exclusively on cross-sectional data, using self-reports of sleep and neighborhood characteristics. Building on the existing research infrastructure developed by our teams previously funded, ongoing studies, we have a unique and important opportunity to study whether changes in the built and social environment, stimulated by substantial economic investment improves sleep, and in turn, reduces obesity-related health disparities. The study cohort includes a randomly selected cohort of 1380 low-income, African American adults, from two urban neighborhoods, one of which is undergoing a dramatic revitalization over the next 5 years (i.e., the intervention neighborhood), and the other (the sociodemographically-matched control neighborhood) is not undergoing any such changes. We will use longitudinal assessments of sleep using actigraphy, self-reports, and in a subsample of 300, objective, in-home monitoring of obstructive sleep apnea, to provide a rich characterization of sleep profiles before, during, and, after neighborhood changes. Evidence gained from this study would have substantial scientific and policy implications for identifying novel individual-level and neighborhood level factors that contribute to striking and pervasive racial and socioeconomic disparities in health.
