Association between blood groups and blood hemoglobin levels in rural population of Kanchipuram district of Tamil Nadu

Background: There are several studies reported on the association between blood groups and hemoglobin phenotypes. There are few older studies which have reported the higher incidence of hemolytic anemia in certain blood groups. Pernicious anemia is commoner in A blood group males and females. Aim and Objective: The aim is to find the mean hemoglobin values for various blood groups and to find out if there are any significant differences in the values in different blood groups. Materials and Methods: A total number of 269 subjects were recruited for the study. The randomly selected population consisted of 158 males and 111 females. The randomly selected population consisted of 158 males and 111 females. Blood hemoglobin levels were estimated using the instrument hemo control. Blood hemoglobin levels were estimated using the instrument hemo control. Results: B+ve was the most common followed by O+ve blood group. O−ve, with around 0.4% prevalence, was the least of all blood groups. There was a significantly high value of hemoglobin occurring in the O+ve individuals (hemoglobin values of 15–16.5 g/dL) as compared to the A+ve individuals. There was a significantly high value of hemoglobin occurring in the O+ve individuals (hemoglobin values of 15–16.5 g/dL) as compared to the A+ve individuals. Conclusion: Our study done on the rural population of Kancheepuram district showed significantly higher hemoglobin values in O blood group than the A and B blood groups. Rh-negative blood groups had low hemoglobin values when compared with Rh+ve blood groups. [Natl J Physiol Pharm Pharmacol 2020; 10(6.000): 495-498]
