High burden of hypertension amongst adult population in rural districts of Northwest Ethiopia: A call for community based intervention.

ABSTRACT

BACKGROUND: Hypertension is a serious public health issue in Ethiopia, but there is a paucity of evidence in the country's rural areas. The aim of this study was to determine the prevalence of hypertension and its risk factors among adults in rural districts in northwest Ethiopia. METHODS: A community-based cross-sectional study was conducted from June to October 2020. The 1177 study participants were chosen using a multistage sampling procedure. A face-to-face interview was conducted using an adapted version of the WHO STEPwise approach questionnaire. Blood pressure was measured three times using an aneroid sphygmomanometer, and the mean of the last two readings were used for the analysis. Data was entered using Epidata and analyzed using STATA-16. Multivariable logistic regression was used to identify risk factors associated with hypertension. RESULTS: Of the total participants, 218 (18.5%) were found to be hypertensive. The prevalence of hypertension consistently increases with age. Hypertension was positively and significantly associated with female sex ((adjusted odd ratio (AOR) = 2.30, 95% CI 1.53, 3.45)), age group 45-54 years (AOR = 4.63, 95% CI 1.01, 21.37), 55-64 years (AOR = 14.40, 95% CI 3.07, 67.63), ≥65 years (AOR = 19.37, 95% CI 4.03, 93.09), having history of alcohol consumption (AOR = 3.25, 95% CI 1.17, 9.02), used much amount of salt (AOR = 2.37, 95% CI 1.53, 3.60) and too much amount of salt (AOR = 3.78, 95% CI 1.85, 7.72), sleeping for a short duration (AOR = 2.05, 95%CI 1.30, 3.24), and having family history of hypertension (AOR = 2.12, 95% CI; 1.32, 3.39). CONCLUSIONS: Hypertension was significantly high among the rural population we studied and is emerging as a public health problem. Female sex, advanced age, ever used alcohol, excessive salt intake, insufficient sleep, and a family history of hypertension were factors that were positively and significantly associated with hypertension. We recommend local health authorities integrate promotion of hypertension health education, lifestyle modification intervention on salt and alcohol reduction, and hypertension detection, particularly for the female and elderly population, at the health post level to avert the problem.
