OBJECTIVE: The objective of the current study was to assess the secular trends in the prevalence of diabetes, prediabetes, and risk factors from two epidemiological surveys done 10 years apart in three adult populations of different geographic and socioeconomic backgrounds in Tamil Nadu, India. RESEARCH DESIGN AND METHODS: This survey was conducted in 2016 using methodology similar to that used in 2006. Persons aged ≥20 years (n = 9,848) were screened for diabetes, prediabetes, and the risk variables. Fasting and 2-h plasma glucose, lipid profile, blood pressure, anthropometry, and socioeconomic and behavioral details were recorded. Comparative analyses of age-standardized prevalence were done. Prevalence ratios (PRs) between 2016 and 2006 of diabetes and also prediabetes were assessed using Poisson regression analyses. RESULTS: Prevalence of diabetes increased from 18.6% (95% CI 16.6-20.5) to 21.9 (20.5-23.3) in the city, 16.4 (14.1-18.6) to 20.3 (18.9-21.6) in the town, and 9.2 (8.0-10.5) to 13.4 (11.9-14.8) in the periurban villages (PUVs) (P < 0.0001 in all). The PR showed a nonsignificant 8% rise in diabetes in the city, while significant increases had occurred in the town (39%) and PUVs (34%). Prevalence of prediabetes also increased. Age, family history of diabetes, and waist circumference were common risk determinants among the populations. Though general obesity and abdominal obesity increased, the latter was associated with the increased prevalence. CONCLUSIONS: Prevalence of diabetes and prediabetes increased in all locations; the rise was significant only in the town and PUVs. Abdominal obesity is significantly associated with increased trend even among the villagers. Rural populations may be targeted for future public health measures to combat diabetes.
