Associations of different type of physical activity with all-cause mortality in hypertension participants

Few studies explored the association of different type of physical activity with all-cause mortality in hypertension (HBP) participants. A retrospective cohort analysis was performed using National Health and Nutrition Examination Survey (NHANES) data to explore association of moderate-intensity physical activity (MPA), vigorous-intensity physical activity (VPA), sedentary behavior with mortality in HBP individuals. Among 10,913 HBP participants followed for a median of 6.2 years, VPA was not associated with a reduction in all-cause mortality compared to participants without VPA in multivariate Cox survival analysis. MPA was linked to lower all-cause mortality at durations of 0-150 min/week (HR, 0.72; 95% CI 0.58-0.88), 150-300 min/week (HR, 0.71; 95% CI 0.52-0.96), and > 300 min/week (HR, 0.61; 95% CI 0.49-0.77) compared to no MPA. Sedentary behavior of 6-8 h/day (HR, 1.35; 95% CI 1.15-1.59) and > 8 h/day (HR, 1.55; 95% CI 1.34-1.79) were associated with increased mortality risk versus < 6 h/day. Further research is needed to explore whether VPA can improve outcomes for HBP individuals and to determine the optimal duration of VPA.MPA is linked to lower mortality risk, indicating its potential as the best physical activity intensity for HBP individuals.
