Prevalence and Associated Factors of Hypertension Among Adults living in the City of Bandundu, Republic Democratic Republic of the Congo. A Population-Based Cross-Sectional Study.

Abstract

Background and aim: In limited resource settings, reliable epidemiological data generated from hypertension high risk geographical areas or people is a prerequisite for the planning of proven and effective interventions. The aim of the present survey was to assess the prevalence, awareness, control and factors associated with hypertension in adults living in the port City of Bandundu, located in the southwestern part of DRC.Methods: a cross-sectional survey using a modified WHO STEPwise questionnaire for data collection during face-to face interviews was conducted from 1st May to 30th October 2018. A multistage cluster sampling method was used and inclusion criteria were age ≥18 years and informed consent. Information on demographic parameters, behavioral lifestyles, anthropometric and blood pressure (BP) measurements was obtained. Hypertension was defined as an average of two BP ≥ 140/90 mmHg or self-reported history of antihypertensive medication use. Independent factors associated with hypertension were identified using logistic regression analysis. P<0.05 defined the level of statistical significance. Results: The prevalence of hypertension was 34,5% (Women 36,6 %). Older age (p<0.001), subclinical atherosclerosis (p= 0.021), sleep duration <8 hours (p<0.002), diabetes mellitus (p<0.001), and obesity (p= 0.009) emerged as main cardiovascular risk factors associated with hypertension.Conclusion: Hypertension was characterized by a high prevalence, low rate of awareness and suboptimal BP control, high cardiovascular risk and associated sleep duration and obesity as modifiable risk factors.
