Neighborhood Walking Environment and Activity Level Are Associated With OSA: The Multi-Ethnic Study of Atherosclerosis.

ABSTRACT:

Background

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.

Methods

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.

Results

Residing in the lowest quartile walking environment neighborhoods (score < 3.75) was associated with more severe sleep apnea (mean, 2.7 events/h greater AHI [95% CI, 0.7 to 4.6]), after adjusting for demographic characteristics, BMI, comorbidities, health behaviors, neighborhood socioeconomic status, and site. Associations were stronger among obese and male individuals. Approximately 1 SD greater objective activity in men was associated with a lower AHI (mean, -2.4 events/h [95% CI, -3.5 to -1.3]). This association was partially mediated by BMI (P < .001).

Conclusions

Living in neighborhoods with a low walking environment score is associated with greater severity of sleep apnea, especially in male and obese individuals. In men, greater activity level is associated with less severe sleep apnea, independent of BMI, comorbidities, and socioeconomic status. Neighborhood-level interventions that increase walkability and enable increased physical activity may potentially reduce the severity of sleep apnea.

Project description:BackgroundThe neighborhood environment may play a role in encouraging sedentary patterns, especially for middle-aged and older adults.PurposeThe aim of this study was to examine the associations between walking and neighborhood population density, retail availability, and land-use distribution using data from a cohort of adults aged 45 to 84 years.MethodsData from a multi-ethnic sample of 5529 adult residents of Baltimore MD, Chicago IL, Forsyth County NC, Los Angeles CA, New York NY, and St. Paul MN enrolled in the Multi-Ethnic Study of Atherosclerosis in 2000-2002 were linked to secondary land-use and population data. Participant reports of access to destinations and stores and objective measures of the percentage of land area in parcels devoted to retail land uses, the population divided by land area in parcels, and the mixture of uses for areas within 200 m of each participant's residence were examined. Multinomial logistic regression was used to investigate associations of self-reported and objective neighborhood characteristics with walking. All analyses were conducted in 2008 and 2009.ResultsAfter adjustment for individual-level characteristics and neighborhood connectivity, it was found that higher density, greater land area devoted to retail uses, and self-reported proximity of destinations and ease of walking to places were each related to walking. In models including all land-use measures, population density was positively associated with walking to places and with walking for exercise for more than 90 minutes/week, both relative to no walking. Availability of retail was associated with walking to places relative to not walking, and having a more proportional mix of land uses was associated with walking for exercise for more than 90 minutes/week, while self-reported ease of access to places was related to higher levels of exercise walking, both relative to not walking.ConclusionsResidential density and the presence of retail uses are related to various walking behaviors. Efforts to increase walking may benefit from attention to the intensity and type of land development.
