There has been growing interest in understanding how neighborhoods may be related to cardiovascular risk. Neighborhood effects on sleep apnea could be one contributing mechanism. We investigated whether neighborhood walking environment and personal activity levels are related to OSA.

Data were analyzed from a subpopulation of the Multi-Ethnic Study of Atherosclerosis (MESA), including subjects who participated in both the MESA Sleep and Neighborhood studies (N = 1,896). Perceived neighborhood walking environment and subjects’ objective activity were evaluated in multivariate, multilevel models to determine any association with sleep apnea severity as defined by using the apnea-hypopnea index. Sex, race/ethnicity, and obesity were examined as moderators.

Residing in the lowest quartile walking environment neighborhoods (score < 3.75) was associated with more …
