Influence of the Social Environment on Ideal Cardiovascular Health

BACKGROUND: The environment plays a large role in the health of individuals; however, more research is needed to better understand aspects of the environment that most influence health. Specifically, our study examines how the social environment influences cardiovascular health (CVH). METHODS AND RESULTS: The social environment was characterized using measures of belonging and life and work stress in individuals, as well as nationally derived measures of marginalization, deprivation, economic status, and community well‐being in neighborhoods. CVH was defined by the American Heart Association's Cardiovascular Health Index—a summed score of 7 clinical and behavioral components known to have the greatest impact on CVH. Data were obtained from the Canadian Community Health Survey 2015 to 2016 and multiple national data sources. Multilevel regression models were used to analyze the associations between CVH and the social environment. Overall, 27% of Canadians reported ideal CVH (6–7 score points), 68% reported intermediate CVH (3–5 score points), and 5% reported poor CVH (0–2 score points). The neighborhood environment contributed up to 7% of the differences in CVH between individuals. Findings indicated that residing in a neighborhood with greater community well‐being (odds ratio [OR], 1.33 [95% CI, 1.26–1.41]) was associated with achieving higher odds of ideal CVH, while weaker community belonging (OR, 0.67 [95% CI, 0.62–0.72]) and residing in a neighborhood with greater marginalization (OR, 0.87 [95% CI, 0.82–0.91]) and deprivation (OR, 0.67 [95% CI, 0.64–0.69]) were associated with achieving lower odds of ideal CVH. CONCLUSIONS: Aspects of individual‐level social environment and residing in a neighborhood with a more favorable social environment were both independently and significantly associated with achieving ideal CVH.
