Can the association between hypertension and physical activity be moderated by age?

OBJECTIVES: Physical inactivity, hypertension and non-communicable diseases are major public concerns across the globe. To our knowledge, there is a lack of research that has investigated the moderating effect of age on the relationship between hypertension and physical activity in developing countries. This study had two objectives: (1) investigating hypertension and sociodemographic factors associated with physical activity and (2) investigating whether age moderates the relationship between hypertension and physical activity. METHODS: Nationally representative data of Malaysia were used to generate cross-sectional evidence. The sample size was 2156 respondents. An ordered probit regression was utilized to assess factors associated with the practice of physical activity. RESULTS: Respondents aged 40–49 years with hypertension were 7.3% less likely to participate in high-level physical activity when compared to those without hypertension. The probability of having a low level of physical activity was 12.3% higher among hypertensive patients aged ≥60. Males, married individuals, less-educated adults, low-income earners, and individuals who were aware of their BMI, had a higher tendency to indulge in a highly active lifestyle than others. CONCLUSION: The effect of hypertension on physical activity was moderated by age. Factors influencing physical activity levels among adults were income, gender, marital status, education, employment status, and BMI awareness.
