Abstract

Background: Population based survey study on hypertension risk factors among adults in Ethiopia are lacking. The objective of this study was to assess hypertension risk factors among adults aged 1564 years, at Gilgel gibe field research center.

Methods: An analysis of population based cross-sectional survey data on chronic non-communicable diseases was carried out at the Field Center. Four thousand & fifty five individuals (hypertensive=303) were involved for analysis. Principal investigator together with data miner extracts the required data. Bivariate analysis of the association between the explanatory and outcome variable were carried out and assessed using Odds ratio with 95% confidence interval; variables in a binary screening found at p-value ≤ 0.25 candidate, and then Multiple logistic regression analysis employed to find out significant socio-behavioral factors associated with being hypertensive, employing Statistical Program for Social Science version 20.0.

Result: Four thousand and fifty five (90.7%) out of the planned sample engross in the analysis (hypertensive =7.5%; women 179 (4.4%; No hypertensive = 92.5%). And the age groups of 45-54 years were substantial number of suffering hypertension 67(7.8%). Female, able to read and write only, alcohol binge women and vigorous recreational exercise were predictors of hypertension. Men and urban residents were less likely to be hypertensive (Odd Ratio =0.74 and, 0.82, respectively). Current Khat chew was highest among hypertensive (Odd Ratio =1.07(95%CI: 0.84-1.36). Reported risk factor: low fruit &/ or vegetable serve was the highest both in normotensive (42%) & 43% in hypertensive, and total level of physical inactivity was the lowest among hypertensive (1.7%), and current alcohol consumption 5.5% among normotensive. The results of bivariate analysis illustrated female, alcohol binge women and vigorous exercise in leisure were statistically significant with Odd Ratio of (1.35, 6.12 and 2.03) times more likely hypertensive, respectively. Then multivariate analysis, denote the Odd Ratio value of being female was 1.32, able to read and write only 1.60, binge women 6.78 and vigorous recreational activity 2.61 times more likely to have the disease.

Conclusion: Risk factors for hypertension were common, so provision of health education, strength a surveillance system for hypertension and its risk factors and further extended studies including biological risk factors; is necessary to reduce the burden of hypertension, in the survey population.
