To estimate the prevalence of hypertension and its determinants among Bangladeshi type-2 diabetic and non-diabetic subjects.Design and Method:
A cross-sectional study was conducted among 18697 subjects (11917 diabetic and 6780 non diabetic) purposively from selected 16 diabetic hospitals health centre located in the capital, Dhaka and in northern part of Bangladesh. Data were collected using a pre-tested, semi-structured questionnaire by face to face interview. Anthropometric measurement and biochemical analysis were done by standard techniques. Hypertension was diagnosed using International Diabetes Federation (IDF) criteria for this population. Data were analyzed by univariate as well as bivariate analysis. Logistic regression was applied to estimate the odds ratio (OR) and corresponding 95% confidence intervals (CI) for the different explanatory variables.Results:
Of the total subjects, 42% were male and 58% were female. The mean age (±SD), years of the non diabetic and diabetic subjects was 46 (±14) and 49 (±7), respectively. The corresponding values for BMI were 23.7 (±3.8) and 25.4 (±3.9). The diabetic group had a substantially higher proportion of hypertensive subjects compare to the non diabetic group (38% vs 7%). On logistic regression analysis, hypertension was found to have strongly significant (p < 0.001) association with increasing age, urban resident, higher socioeconomic status, smoking, higher BMI and waist hip ratio and raised total cholesterol.Conclusions:
Bangladeshi type 2 diabetes mellitus subjects are about 5 times more prone to hypertension compared to their non diabetic counterparts. Irrespective of the presence of diabetes age, urbanization, high-low economic status, generalized and central obesity and hypercholesterolemia an independent risk factors of hypertension in this population.
