Combined association of aerobic and muscle strengthening activity with mortality in individuals with hypertension

Evidence on the association between meeting both aerobic physical activity (PA) and muscle-strengthening activity (MSA) guidelines with mortality in individuals with hypertension is scarce. We included 34,990 adults from the 2007 to 2013 Korea National Health and Nutrition Examination Survey, linking mortality follow-up data until 2019. Adherence to PA guidelines was assessed based on the current PA guidelines using a self-reported questionnaire and categorized as follows: meeting MSA only, aerobic PA only, both MSA and aerobic PA, or neither. Associations of hypertension and adherence to PA guidelines with all-cause and cardiovascular disease (CVD) mortality were examined using Cox proportional hazard models. Over 9.2 years, 1948 participants died from any cause and 419 from CVD. Meeting both PA guidelines was associated with the lowest risk of all-cause and CVD mortalities in the total sample regardless of hypertension status. In individuals with hypertension, meeting aerobic PA guidelines only had a 24% lower risk of both all-cause and CVD mortality, and meeting both PA guidelines further reduced risks by 40% and 43%, respectively; however, meeting MSA guidelines only was not associated with either all-cause or CVD mortality. In individuals without hypertension, only meeting both MSA and aerobic PA guidelines, but not meeting either MSA or aerobic PA guidelines, showed reduced risk of CVD mortality. In Korean population, non-hypertensive individuals who met both guidelines had a lower risk of CVD mortality. However, hypertensive individuals showed a reduced risk of both all-cause and CVD mortality when meeting aerobic PA or both guidelines, but not MSA alone.
