Resumo

This study examined the combined effects of sedentary behavior and moderate-to-vigorous physical activity (MVPA) on cardiovascular health in older Latinos. In a cross-sectional sample of 147 older, community-dwelling Latinos, time spent in sedentary behavior and MVPA were obtained using accelerometers. Analyses examined the effects of a measure of physical activity that combined levels of sedentary behavior (± 10 daily hours) and MVPA (< 30, 30-150, or > 150 weekly minutes) on cardiovascular health outcomes (blood pressure, BMI, waist circumference, cardiorespiratory fitness). Results suggest that cardiovascular health benefits of MVPA on BMI (p = .005), waist circumference (p = .002), and cardiorespiratory fitness (p = .012) may depend on a participant's level of sedentary behavior. For all three, health benefits of 30-150 weekly minutes of MVPA were found only for those without excessive sedentary behavior (≥ 10 hr). Sedentary behavior may negatively impact cardiovascular health despite moderate participation in MVPA. Health guidelines should suggest reducing sedentary behavior while increasing MVPA.
