Abstract
Purpose: The study aimed to explore the effects of physical activity on indicators for cardiovascular risk in a sample of community-dwelling older adults with hypertension.Methods: This longitudinal study used data collected from the Elderly Cohort Database of the National Health Insurance Service in South Korea between 2002 and 2013. Participants included 10,588 older adults (≥ 60 years) with hypertension. Data assessing self-reported physical activity, blood pressure, fasting blood glucose, body mass index, and total cholesterol levels throughout the 12-year study were extracted from the original database and analyzed. Participants were categorized into 4 groups based on the reported changes in physical activity over time; Group I (totally inactive), II (inactive to active), III (active to inactive), and IV (totally active). Cox proportional hazard model was used to confirm the risk of cardiovascular indicators over time in each group.Results: Participants’ mean age was 64.2 years in the initial year of 2002. The number of participants in Groups I, II, III, and IV was 4032, 2697, 1919, and 1940, respectively. Group IV showed a significant decline in risk for uncontrolled hypertension compared to Group I (HR = 0.87, 95% CI [0.800-0.948]). Group II showed a significant decrease in risk for uncontrolled diabetes compared to Group I (HR = 0.94, 95% CI [0.888-0.999]).Conclusions: Physical activity is an essential non-pharmacological and self-management intervention that can be easily implemented among older adults with hypertension. Healthcare providers should be aware of the importance of older adults’ physical activity and encourage them to perform and maintain it steadily for better long-term cardio-metabolic outcomes.
