Date Published: 2023-07-12

Abstract:
Objective To determine the magnitude of hypertension, its association with obesity and the associated factors among employees of Wallaga University, Ethiopia. Design, setting and participants 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. The main outcome measured 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. Results 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. Conclusion 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.

Introduction:
Hypertension is a major global public health problem. It is the most common cardiovascular disorder affecting approximately 1.39?billion people globally, of these approximately three-quarters of individuals with hypertension lived in low-income and middle income countries. 1 2 In Africa, 46% of adults 25 years and above had hypertension as of 2008. 3 Sub-Saharan Africa had the highest burden of raised blood pressure compared with high-income countries. 2 The prevalence of hypertension in sub-Saharan Africa…
