Physical activity, stress, and cardiovascular disease risk: HCHS/SOL Sociocultural Ancillary Study

Abstract

We assess whether the cross-sectional associations between moderate-vigorous physical activity (MVPA) and CVD risk factors are modified by various stress types. Complete baseline data from 4,000 participants, ages 18–74 years, of the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study (HCHS/SOL SCAS) were analyzed using complex survey design methods. Accelerometer-measured MVPA was assessed continuously (average minutes per day). CVD risk factors assessed were diabetes, hypercholesterolemia, hypertension, and obesity. Stress was assessed using the Chronic Burden Scale for chronic stress, Traumatic Stress Schedule for traumatic stress, and the Perceived Stress Scale for perceived stress. Poisson regression models estimated prevalence ratios of CVD risk factors. The interaction was evaluated by cross-product terms with p <0.10. There was a significant interaction between chronic stress and MVPA among those with prevalent diabetes (pinteraction = 0.09). Among those reporting low chronic stress, higher MVPA was associated with a low prevalence of diabetes, however among those reporting high chronic stress, the prevalence of diabetes remained high even with higher MVPA. We did not observe interactions between chronic stress and MVPA for the remaining CVD risk factors, or interactions between traumatic stress or perceived stress and MVPA. This study provides initial evidence on the role of chronic stress on the association between MVPA and diabetes for Hispanic/Latino adults. Mostly, however, chronic stress, traumatic stress, and perceived stress did not modify the associations between MVPA and CVD risk factors for Hispanic/Latino adults.
