Background: Blood is an unique connective tissue which confers identity to an individual with blood group and type. Blood group has clinical importance in transfusion medicine. One of the major health problems in the world is malnourishment, of which anemia contributes to a vast subset, especially in developing countries. Decreased hemoglobin levels in turn adversely affect functioning of other systems of the human body. Blood group association with diseases like gastric cancer, pernicious anemia are proven. Previously, some studies had varied results analysing association of anemia with different blood groups. So, the present study was done to throw light on Hb levels and blood groups. Objective: The objective of this study was to find out the distribution of blood groups, the variation of hemoglobin concentration of the subjects, if there is any association of low Hb levels and blood groups. Methods: First MBBS and BDS students of the academic year 2018–2019 who were admitted in Mamata Medical College were taken as subjects and their blood grouping was done using standard antisera method.The hemoglobin content of the subjects was estimated with the help of Sahli’s hemoglobinometer. Results: The blood group distribution was O (44.87% ), B (27.31% ), A (23.85%), AB ( 3.90% ). 12.72% males were anemic and 84.66% females were anemic. The distribution of anemia in blood groups was O with 7.31%, A with 4.87%, B of 4.39% and AB with 0.97%. The Chi-square value was 0.76 with p value of 0.85 which is insignificant. Conclusion: Anemia was found to be more in subjects with O blood group and less in case of persons belonging to AB group. The blood groups were seen to follow the Asiatic trend (O > B > A > AB). Females were anemic may be due to reduced red blood cell mass influenced by high estrogen levels.
