Baseline prevalence of high blood pressure and its predictors in a rural adult population of Bangladesh: Outcome from the application of WHO PEN interventions

Abstract

This cross-sectional study estimated the prevalence of high blood pressure (BP) and examined its predictors at baseline following protocol 1 (actions 1 and 2) of World Health Organization (WHO) Package of Essential Noncommunicable Disease (PEN) Interventions in a selected rural area of Bangladesh. A total of 11 145 adults (both sex and age ≥ 18 years) completed both the questionnaire and clinical measurements at the household and community clinics, respectively. We defined high BP as systolic BP ≥ 120 mmHg or diastolic BP ≥ 80 mmHg, prehypertension (pre-HTN) as systolic BP 120-139 mmHg or diastolic BP 80-89 mmHg, and hypertension (HTN) as systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg and/or anti-hypertensive drug intake for the raised BP. The prevalence of high BP was 51.2% (pre-HTN, 25.3%; HTN, 25.9%). Among them, the proportion of pre-HTN was higher among men (28.7%) while HTN was higher among women (27.4%). Other than fast food intake (pre-HTN, OR: 1.110, P = .063) and women sex (HTN, OR: 1.236, P < .001), the pre-HTN and HTN had higher odds for having same predictors as follows: age ≥ 40 years, family history of HTN, physical inactivity, central obesity, generalized obesity, and diabetes. In conclusion, the application of WHO PEN protocol 1 detected one-fourth of the rural adult population had pre-HTN and HTN respectively, and the common significant predictors of those were the age, family history of HTN, physical inactivity, generalized obesity, and diabetes.
