Series of epidemiological studies have been carried out by the research team since 1988 studying the changes in the prevalence of T2DM, prediabetes and associated risk factors. These studies have shown that the determinants to rising prevalence of diabetes vary among populations and with time. Comparative studies from the same region can help to understand the temporal changes occurring in a specific population. In this proposal we intend to conduct a cross-sectional survey in varied levels of urbanisation and compare the findings with our earlier reported data to assess the degree of changes in dysglycaemic prevalences. The primary aim of the proposal is to study the temporal changes and the prevalence of diabetes, prediabetes and associated cardio-metabolic risk factors in varying levels of urbanization. A multi-stage random selection method will be used. Field workers will conduct an enumeration of the individuals above 20 years of age. In each location, streets will be randomly selected to have an equal representativeness from different socio-economic strata. All eligible occupants (family members) of the selected households will be invited for the survey. The study outcomes will be of relevance in public health research in modeling effective national healthcare policies.
