Non-Pharmacological Management of Hypertension: Exploring Determinants for Optimizing Physical Activity Implementation in Cameroon

TL;DR

This study explores why many hypertensive patients in Cameroon are physically inactive and suggests ways to improve physical activity through targeted interventions.

Contribution

The study identifies sociodemographic and clinical predictors of physical inactivity in hypertensive patients in Cameroon, offering insights for culturally adapted interventions.

Findings

54% of hypertensive patients in Cameroon were insufficiently active, with older age and comorbidities strongly associated with inactivity.

Higher education levels were protective against inactivity, while barriers like lack of motivation and physical impairment were commonly reported.

Tailored interventions targeting older adults, women, and patients with comorbidities are needed to improve physical activity adherence.

Abstract

Physical activity (PA) is a cornerstone of non-pharmacological hypertension management, yet evidence on its determinants remains limited in African populations. We conducted a cross-sectional study among 383 hypertensive patients in two referral hospitals in Cameroon to assess PA levels and associated factors. PA was classified as insufficiently active (<600 MET-min/week) or active (≥600 MET-min/week). Overall, 54% of participants were insufficiently active, 37.9% had moderate activity, and 8.1% reported vigorous activity. Older age was strongly associated with inactivity, particularly for ages 60–74 (aOR = 2.84, p < 0.001) and for ≥75 years (aOR = 18.67, p < 0.001). Comorbidities also predicted inactivity, including renal failure (aOR = 2.41, p < 0.001) and diabetes/other complaints (aOR = 4.92, p < 0.001). Female sex increased the odds of inactivity (aOR = 1.42, p = 0.038). Whereas higher education was protective, particularly secondary (aOR = 0.12, p < 0.001) and high-school level (aOR = 0.05, p < 0.001). Among inactive participants, the most frequent barriers were lack of motivation (38.6%), physical impairment (37.2%), lack of prescription (23.2%), and space constraints (21.7%), whereas perceived benefits (39.1%), motivation (26.1%), and available space (32.4%) were the most cited facilitators; however, none of these factors showed a significant association with PA in chi square analysis. The high prevalence of inactivity and the strong influence of sociodemographic and clinical characteristics underscore the need for tailored interventions that target older adults, women, and patients with comorbidities, while strengthening education and structured support for PA within hypertension care pathways.
