Overweight and abdominal obesity as determinants of undiagnosed diabetes and pre-diabetes in Bangladesh

Type 2 diabetes and pre-diabetes are an increasing pandemic globally and often remain undiagnosed long after onset in low-income settings. The objective of this study is to assess the determinants and prevalence of undiagnosed diabetes and pre-diabetes among adults in Bangladesh.In an exploratory study, we performed oral glucose tolerance test on 1243 adults ≥20\ua0years of age from urban Mirpur, Dhaka (n = 518) and rural Matlab, Chandpur (n = 725) who had never been diagnosed with diabetes or pre-diabetes. We collected data on socioeconomic, demographic, past medical history, physical activity, and measured weight, height, waist and hip circumferences, and blood pressure. Risk factors associated with undiagnosed diabetes and pre-diabetes were examined using a multiple logistic regression model.Overall prevalence of diabetes and pre-diabetes was 6.6\ua0% (95\ua0% CI 5.3, 8.1) and 16.6\ua0% (14.5, 18.7) respectively, with both being significantly higher in urban than rural populations (diabetes 12.2\ua0% vs 2.6\ua0% respectively, p
