Abstract: Diabetes is one of the largest health emergencies of the 21st century. In future there will not only be increase in the incidence and prevalence of diabetes but also there will be an increase in economic burden, disability and life years lost due to disease. Microalbuminuria is used as predictor for early micro and macrovascular changes in diabetes. The objectives were to find out the prevalence of microalbuminuria among type II diabetes mellitus patients in urban Chidambaram and to find out the association between albuminuria and age, sex, duration of diabetes.A descriptive cross sectional study was carried out in the urban field practice area of urban health centre between October 2015 and July 2016, among 200 study participants who had type II diabetes mellitus. The prevalence of microalbuminuria among the study participants was 41.5%. All the three risk factors age, sex and duration of diabetes mellitus were found to have significant association with occurrence of albuminuria. As the age increased the probability of being microalbuminuric also increased (P<0.05). Males had 2.9 times the risk of being microalbuminuric than the females. As the duration of diabetes mellitus increased the chance of being microalbuminuric also increased (P<0.05).Life style modifications and other measures which can postpone the age of onset of type II diabetes mellitus can aid in decreasing the mean duration of diabetes mellitus with age.Studies with analytical designs should be performed in the same area for deeper understanding of the role of risk factors for the occurrence of microalbuminuria in the indigenous population.
