Comparative study of physical activity of hypertensives and normotensives: A cross-sectional study of adults in Saudi Arabia

Background: To formulate all intervention strategies for hypertension in the community, it is essential to quantify the magnitude of the disease and its risk factors. The patterns of physical activity have not been studied in terms of their being a risk factor or a predictor of hypertension in Saudi Arabia. Materials and Methods: This was a community-based cross-sectional study using the STEP-wise approach of adults and a multistage, stratified, cluster random sample. Data were collected using a questionnaire which included sociodemographics, blood pressure, patterns, levels and duration of physical activity. Results: Of a total of 4758, 1213 (25.5%) were hypertensives. Hypertension was significantly negatively associated with total levels and duration of physical activity in leisure, transport, and work. Significant predictors of hypertension included lower levels of work involving a moderate physical activity for 10 min, walking/cycling for 10 min continuously, and vigorous activity during leisure time. Conclusions: Hypertension is prevalent among adults; physical inactivity is a significant risk factor and predictor. Targeting this modifiable risk factor can help in prevention, early diagnosis, and control.
