Keywords: hypertension; bank workers; harar town; blood pressure; prevalence; systolic; diastolic
Background: Hypertension clinically defined as a blood pressure of 140/90 mmHg or more on at least two readings on separated time. It is one of the most prevalent non communicable diseases and the most important preventable risk factor for premature death worldwide, due to heart disease and stroke. It is the most important modifiable risk factor for coronary heart disease, stroke, congestive heart failure, end stage renal disease and peripheral vascular diseases
Objective: To assess the prevalence of hypertension and its associated factors among bank workers in Harar town, Eastern Ethiopia 2018
Methods and material: Institutions based cross sectional study was conducted on 149 Bank workers in 6 governmental and 19 private banks which were found in Harar Town. Sample was allocated proportionately and study participant was selected by simple random sampling. Collected and checked data were entered in to Epi Data software version 3.02 and exported and analyzed using SPSS version 21. Descriptive statistics were used to determine prevalence such as frequency, percentage, mean and ratio. Both Bivariate and multiple logistic regressions were used to observe the association between the outcome variable and associated factors. P value less than 0.2 in Bivariate analysis was transferred to multivariate analysis and P value less than or equal to 0.05 was considered as level of statistically significance.
Result: The prevalence of hypertension on this study was 27.5 %. Among study participant 6(4%) had diagnosed with hypertension and only 3 (2%) had on treatment and follow- up. 26(17.4%) bank workers BMI Was obsessed. In multivariable logistic regression analysis Age, Sedentary life style and BMI of bank workers had significant association with hypertension
Conclusion and recommendation: The prevalence of Hypertension in the study was 27.5% Age, Sedentary life style and BMI (Obesity) in this study was positively associated with higher odds of having hypertension. Regular blood monitoring, conducting physical exercise and reduction of Alcohol consumption and street Treatment care and follow-up strategy need to be maintained.
Hypertension clinically defined as a blood pressure of 140/90 mmHg or more on at least two readings on separated time. It is one of the leading causes of global burden of disease. It is being the root cause of many of the body system and organs failure remains to be a major public health challenge globally. [1] It is one of the most prevalent non communicable diseases and the most important preventable risk factor for premature death worldwide, due to heart disease and stroke [2] Hypertension is the most important modifiable risk factor for coronary heart disease, stroke, congestive heart failure, end stage renal disease and peripheral vascular diseases [3].
Statement of the problem
Globally, the overall prevalence of Hypertension in adults aged 25 and over was around 40% and was estimated to cause 7.5 million deaths, about 12.8% of the total of all deaths worldwide and the number of people with uncontrolled hypertension increased by 70% between 1980 and 2008 The rising epidemic of hypertension is thought to be due to mechanization, population growth and ageing [4, 5] By 2025 the number of hypertensive people is expected to increase by 60 % and reach 1.56 billion people [6]. The prevalence of hypertension varies worldwide in Africa indicated the overall prevalence of hypertension have been increasing since 1990. In adults aged ≥20 years, in 1990 the prevalence was 19.1% , in 2000 prevalence were estimated 24.3%,in 2010 with prevalence of 25.9% and it will projected to 25.3% by 2030 [7]. In sub-Saharan Africa estimated in 2008 was 13.7% in rural areas, 20.7% in urban area, 16.8% in males, and 15.7% in women [8]. The pooled prevalence of hypertension among the Ethiopian population was 19.6 % and 20.6 % in male and 19.2% in female. There is no sufficient data in the study area therefore this study was intended to provide compressive and up to date evidence on the prevalence and investigate the associated factors of Hypertension among Bank Workers of Harar town, Eastern Ethiopia.
Significance of the study: The study will describe the current situation of HPN in among bank workers in Harar town and it will be helpful for sampled population to know their BP status and for early linked to health institution to management if they have HTN. It will also be important for concerned bodies for prevention and management of hypertension. It will be serving as a base line data for others researchers.

Factors Associated with Hypertension:
In multivariable logistic regression analysis Age, Sedentary life style and BMI of bank workers had significant association with hypertension. Bank workers whose age 25 – 44 years had 75.8% (AOR= 0.242, 95% CI: 0.065 – 0.904) less likely had hypertension than age 24 years. Those who had sedentary life style had 3 times (AOR= 2.925, 95% CI: 1.085 – 7.885) more likely, Obesities bank workers were 6 times more likely (AOR= 6.113, 95% CI: 1.030 – 36.28) having hypertension than their in counters.

In this study the prevalence of hypertension was, 27.5% the finding was greater than study done in Owerri Nigeria which was 12.4% [10] and Addis Ababa the prevalence was 19.1% [9].This discrepancy may be due to different age category of participants as well as BMI and socio cultural variation. But the study outcome is less than the result of study done among bank workers in Surratt city of India which was 30.4% [11] and Ghana 38 % [12]. The difference occurred possibly due to different in socio demographic and socio-cultural as well as life style and mean value different in BMI.
The study found that age of bank workers was significantly associated with Hypertension. Those age 24 – 45 were 75.8 % less likely had hypertension than bank worker whose their age was less than 24 years. But study conducted in Adiss Abeba on federal ministry civil servants showed that increased age was identified as a factor for hypertension. Study participants older than 48 years were more likely to be hypertensive than those less than 27 years [13] and study of bank employees of Surratt city in India also showed that age ≥ 50 years increase the risk of hypertension [11]. Even if the age associated to had hypertension there is different in association of age categories. The variance may be due to having more sedentary life style in our study.
In this study the risk of being hypertensive was 3 times more likely among bank workers who had sedentary life style this finding was in line with study conducted in Surratt city of India 2 times more likely [11] and Ghana Accra. This shows that sedentary life decrease energy expenditure and increase cholesterol level in blood vessel which directly related with Cardio vascular disease i.e. Hypertension .
BMI of bank workers significant association with Hypertension, in this study obese bank workers were 6 times more risked for hypertension this finding also in line with study conducted in Adiss abeba which is obese were 7.36 times more likely to be hypertensive and in Sullia Taluk, Karnataka also obesity was strongly associated with hypertension.[14].
Conclusion and recommendation
Conclusion
The prevalence of Hypertension in the study was 27.5% which shows the high prevalence of hypertension in the study population. As in many other developing countries hypertension is becoming a serious public health concern among working bankers in Harar town, Eastern Ethiopia. Age, Sedentary life style and BMI (Obesity) in this study was positively associated with higher odds of having hypertension. However Sex, Marital status, educational level, Job description, alcohol drinking, smoking, salt usage, physical activity and working schedule had not associated with hypertension.
