BACKGROUND ABO blood group system was defined based on the presence of blood group antigens present on the cell membrane of erythrocytes. Though human beings possess the same blood group system, the prevalence of blood group system varies markedly across races, ethnic groups etc. This study aimed to look at the prevalence of ABO and Rh blood group among the medical students. METHODS An observational study was conducted among the type 2 diabetic subjects. Details of demographic data were collected along with ABO and Rh blood group details. The data was analysed. RESULTS Total 513 subjects were selected for the study. Among the study population, there were 200 females and 313 males. The order of prevalence of diabetes mellitus noted in the blood group types were O, B, A and AB respectively. The maximum prevalence of type 2 diabetes mellitus was noted with O blood group with 35.3 % and the least with blood group AB with 10.5 %. CONCLUSIONS The most common blood group linked to type 2 diabetes mellitus among this study population is O and B. Least prevalence is noted with blood group AB. 92% of the diabetics was Rh positive, while the rest of the population was Rh negative.
