Abstract：Objective To explore the relationship between regular physical activity and physical indicators of the elderly, to analyze the related factors of hypertension, and to provide useful references for conducting health interventions in the elderly. Methods Stratified random cluster sampling method was used to select 1,555 senior citizens in ten cities of Shaanxi Province in 2015, and their age, sex, height, weight, waist circumference, blood pressure and regular physical activity were investigated and analyzed. Results The participation rate of regular physical activity in the elderly surveyed was 51.38%. We grouped the elderly according to regular physical activity, and there were statistically significant differences in height (t=2.054, P=0.040), body weight (t=2.411, P=0.016), waist circumference (t=3.339, P=0.001) and waist-to-height ratio (WHtR) (t=3.601, P=0.000,) between regular physical activity group and non-regular physical activity group. The prevalence rate of hypertension in the elderly was 35.1%. Exercise frequency (B=-1.646, P=0.000), exercise duration (B=0.943, P=0.000) and WHtR (B=0.395, P=0.013) were the factors affecting the prevalence of hypertension in the elderly, while BMI was not (P>0.05). Conclusions Regular physical activity can help the elderly increase the proportion of physical muscles, reduce the risk of central obesity, and improve the blood pressure level. The prevalence of hypertension in the elderly is closely correlated with the frequency and duration of exercise and WHtR. It is necessary to monitor the fatigue condition when we conduct regular physical activity intervention targeted on the risk factors of hypertension in the elderly.
