Abstract

ABO and Rh blood group systems have been associated with a number of diseases including type-2 diabetes mellitus (T2DM). Epidemiological studies have inconsistently associated ABO and Rhesus (Rh) blood groups with T2DM risk. To assess the distribution of ABO and Rh blood groups among type-2 diabetic subjects and to check the potential association between ABO and Rh blood groups with T2DM. This small retrospective case-control study was conducted at DM WIMS Hospital, Wayanad. One-year data (from Jan-18 to Jan-19) of fasting, postprandial or random plasma/serum glucose, HbA1c, ABO and Rh blood groups of Non- diabetic and type -2 diabetic subjects were collected from the Hospital Clinical Laboratory Medicine department. Among 280 randomly selected data, 147 are non-diabetic subjects, and 133 are confirmed and known cases of type 2 diabetic mellitus. Subjects with Blood group B has the highest distribution percentage among group-2 (59.39%) in comparison with group-1 (34.02%), followed by A (19.55%), O (18.79%), AB (2.27%). Statistical analysis using Chi-square test among ABO and Rh blood groups between group-1 and group-2 showed a significant (p< 0.001) association of blood group “B +ve” and least association of blood group “O +ve” with T2DM. However, the Rh Blood groups evaluation for T2DM showed no clear association, as both Rh +ve and Rh -ve were uniformly distributed in the groups. The ABO and Rh blood groups may have a possible role to play in the development of T2DM. The subjects with B + ve blood group are at greater risk for T2DM and O + ve blood group individuals are at lower risk for T2DM.
