Prevalence of diabetes in a suburban population of Bangladesh.
To determine the prevalence of diabetes and hypertension, 6847 subjects of age 15 years or older, were investigated in a suburban population in Bangladesh. Fasting and post-prandial (capillary) blood glucose (2-hPG) was estimated. According to WHO criteria the crude prevalence of impaired glucose tolerance (IGT) was 7.5% and non-insulin-dependent diabetes mellitus (NIDDM) was 4.1%. The age standardized (30-64 years) prevalence of IGT was 7.7% with 95% confidence interval (CI) 6.96-8.44 and NIDDM was 4.5%, CI 3.94-5.12. Compared with the younger subjects the older subjects (< 40 vs. > or = 40 years) showed significant association with IGT (chi2, 65.9; P < 0.001) and NIDDM (chi2, 92.0; P < 0.001). Higher BMI (< or = 22.0 vs. > 22.1) was also significantly associated with IGT (chi2, 16.6; P < 0.001) and NIDDM (chi2, 83.9; P < 0.001). The higher BMI had stronger association with NIDDM than with IGT. Lower height showed significant association only with NIDDM. The logistic regression analyses also showed that increased age, higher BMI and short stature were independent risks for NIDDM. The study showed an increased prevalence of IGT and NIDDM among the suburban population of Bangladesh and the excess risk was observed with increased age, higher BMI and short stature.
