This study is the first one to determine the prevalence and associated risk factors for Hypertension among the Bihari community of Bangladesh, a neglected minor ethnic group of population living in different camps with poor facilities for more than four decades. Being poor and illiterate, they are also unaware of the dangers of major NCDs. So, it is important to know the current situation of Hypertension and other NCDs of this community.
Design and Method:
This cross-sectional study was conducted among subjects, aged ≥ 30 years in Bihari camp at Mirpur of Dhaka city. Along with Blood pressure measurement, OGTT, anthropometric measurements and biochemical tests were obtained. Stata 13 was used for data entry and analysis. Statistical comparisons were carried out using t-test and χ2 test. Logistic regression was applied to calculate crude and adjusted odds ratio to identify risk factors.
The prevalence of Hypertension was 7.03% in this study group. Prevalence of Hypertension was greater in females than males. Increased blood pressure was significantly (p < 0.05) associated with type 2 DM, increased Triglyceride and Cholesterol level. It has been also observed that positive family history of DM and high BP along with obesity significantly affected the probability of Hypertension. The higher waist circumference had significant (p < 0.05) association with high BP in both sex.
The prevalence of Hypertension in the study population was found to be almost equal to that of the general population of Bangladesh. Therefore, the policy makers should initiate cardiovascular care with health education in the minor ethnic groups and whatever the causes, they must be included in the country's health policy regarding development of prevention and control model of noncommunicable diseases.
