Background: Hypertension is defined as two or more readings of systolic blood pressure measurement of 130 mm Hg or higher or diastolic blood pressure measurement of 80 mm Hg or higher. Symptoms of hypertension (HTN) are often not detectable at early stages and because of this many people with the disease are mostly left undiagnosed. Undiagnosed HTN is the one that increases the risk of complications such as renal failure, heart failure, myocardial infarction, stroke and premature death. There is no report concerning undiagnosed hypertension in the area. This study is aimed to assess prevalence of undiagnosed hypertension and its associated factors among adult peoples.Method: Community based Cross-sectional study design was conducted. English version questionnaire was used to collect data from 574 households. The data was collected and analyzed by SPSS version.23. The association between dependent and independent variables was tested by using multivariate regression at P-value less than 0.05 and 95% CI.Result: Out of 590 participants, 108 (18.8%) respondents were cigarette smokers and 143 (24.9%) were khat chewers. About 106 (18.5%) of respondents have sedentary lifestyle. A total of 260 (45.3%) of respondents were identified as having undiagnosed hypertension. Respondents having sedentary life style had about 2.24 time’s higher risk of undiagnosed HTN than those who didn’t have sedentary life style. BMI, sedentary life style, cigarettes smoking, health seeking behavior, dietary habit and monthly income were significant predictors of undiagnosed HTN.Conclusion: Based on the identified high prevalence of undiagnosed hypertension, the finding suggests awareness creation for community members about undiagnosed hypertension, its symptoms and ways of managing it.

There is paucity of data concerning undiagnosed hypertension in southern Ethiopia. This study is aimed to assess prevalence of undiagnosed hypertension and its associated factors among adult peoples.Method: Community based Cross-sectional study design was conducted. English version questionnaire was used to collect data from 574 households. The data were collected and analyzed by SPSS version.23. The association between "blood pressure and socio-demographic characteristics', life style factors, behavioral factors..." was tested by using multivariate logistic regression at P-value less than 0.05 and 95% CI.Result: Out of 574 participants, 108 (18.8%) of the study participants were current cigarette smokers and 143 (24.9%) were khat chewers. A sedentary lifestyle was seen in 106 (18.5%) of the studied people. Undiagnosed HTN was observed in 47 (15.3%) of the study participants. A total of 260 (45.3%) of respondents were identified as having undiagnosed hypertension. Body mass index (BMI), sedentary life style, cigarettes smoking, health seeking behavior, dietary habit and monthly income were significant predictors of undiagnosed HTN. Conclusion:Almost 50% of the adult population in the southern of Ethiopia shows undiagnosed hypertension and this is significantly correlated with body mass index (BMI), sedentary life style, cigarettes smoking, health seeking behavior, dietary habit and monthly income.
