Blood glucose and cholesterol levels in adult population of Bangladesh: Results from STEPS 2006 survey.

ABSTRACT

BACKGROUND: A nationally representative survey was carried out to determine the distribution of blood glucose and cholesterol in adult population of Bangladesh in the absence of existing data. METHODS: The study adopted a multistage and geographically clustered sampling technique of households. A total of 2610 individuals (1444 men and 1166 women) aged 25-64 years were selected from rural and urban areas. Capillary blood glucose and total cholesterol levels were measured using an overnight fasting state. RESULTS: The mean age of the participants was 41 years [standard deviation (SD), 11 years]. Half of them (49%) were from urban areas. Half of them (51%) had primary or higher education. Mean glucose was 74mg/dL (SD 23mg/dL). Men had higher mean glucose levels (79mg/dL) than women (67mg/dL). Age-standardized prevalence of diabetes (blood glucose level ≥126mg/dL and/or use of anti-diabetic medication) was 5.5%. In men, it was almost two-and-half times (7.6%) compared with women (2.8%). It was also double in urban areas (7.8%) compared with rural areas (3.4%). Mean cholesterol level among all participants was 167mg/dL (SD 26mg/dL). Men and women had almost similar levels (169mg/dL versus 166mg/dL, respectively). Prevalence of high cholesterol level (≥240mg/dL) was very low (1.3%) in both men (2.2%) and women (0.5%). However, the prevalence of borderline high cholesterol was substantial (5.8%) in this sample. CONCLUSION: The prevalence of high hypercholesterolemia is low, whereas there is a high prevalence of borderline high cholesterol and diabetes in the adult population of Bangladesh. This warrants population-based interventions to tackle this problem.
