INTRODUCTION: Blood pressure (BP) control is necessary to prevent fatal events in patients with hypertension. Although physical activity (PA) and sleep quality (SQ) are known to reduce BP, their joint association is yet to be demonstrated. This study aimed to assess the joint association of PA and SQ on BP control among patients with hypertension in Cameroon. METHODS: This was a hospital-based cross-sectional study carried out among outpatients attending Douala General Hospital in Cameroon diagnosed with hypertension. BP was considered to be controlled if it was lower than 140/90 mm Hg. PA and SQ have been assessed using the International Physical Activity Questionnaire and the Pittsburg Sleep Quality Index. Odds ratio and 95% CI have been calculated, and differences were considered significant at P <
.05. RESULTS: A total of 415 participants were recruited, the mean age was 61 (11) years, and 67% were women. Around 66.3% of participants had their BP uncontrolled. Patients with uncontrolled BP had a significantly higher proportion of overweight/obesity (87.3% vs 73.6, P = .001), sedentary time ≥ 2 hours per day (37.1% vs 27.1, P = .043), and low leisure-time PA level (39.6% vs 52.9%, P = .014). After adjustment for confounders, a poor SQ associated with a low PA level significantly increased the odds of having an uncontrolled BP (odds ratio: 2.66
95% CI, 1.13-6.24
P = .025). CONCLUSION: Cameroonian patients with hypertension exhibit a high rate of poor BP control which is significantly associated with poor SQ and low PA level. These 2 parameters should be considered simultaneously for a better prevention of cardiovascular complications.
