Magnitude of hypertension and its association with obesity among employees of Wallaga University, Ethiopia: a cross-sectional study.

Abstract

To determine the magnitude of hypertension, its association with obesity and the associated factors among employees of Wallaga University, Ethiopia. This institution-based cross-sectional study was employed among 588 employees of the university. Respondents were selected by stratified random sampling technique and interviewed with the aid of a structured questionnaire. Hypertension and obesity were measured using WHO Stepwise approach and recommendations. We used a stratified random sampling technique to select 588 employees of the university from 3 August 2021 to 15 October 2021. A structured questionnaire and anthropometric measurements were used for data collection. Multivariable logistic regression analysis was used to determine factors independently associated with hypertension. A p value less than or equal to 0.05 and its 95% confidence level was used to declare the statistical significance. A total of 578 participants consented and completed the study, giving a response rate of 98.3%. The mean age of the respondents was 31.78 years with SD of 5.4. The overall prevalence of hypertension, general obesity and central obesity was 14.4% (95% CI 11.6% to 17.5%), 31.3% (95% CI 27.6% to 35.3%) and 37% (95% CI 33.1% to 41.1%), respectively. Obesity was significantly associated with hypertension (adjusted OR (AOR): 6.3; 95% CI 2.60 to 8.19). Age range from 35 to 46 (AOR 7.01; 95% CI 1.56 to 31.74), age ≥46 years (AOR 8.45; 95% CI 1.14 to 62.04), being non-academic staff (AOR 2.74; 95% CI 1.56 to 4.81), having additional income (AOR 2.48; 95% CI 1.08 to 5.70), physical inactivity (AOR 2.36; 95% CI 1.44 to 3.88) and poor practice of dietary salt consumption (AOR 1.65; 95% CI 1.01 to 2.87) were factors associated with hypertension. One in seven, more than two in seven and nearly two in six of the employees of Wallaga University were hypertensive, centrally obese and generally obese, respectively. There was a positive association between obesity and hypertension. Comprehensive awareness creation and devising workplace intervention strategies are highly recommended to reduce the hypertension burden and associated obesity.
