ABSTRACT
Background — Over the past years, there seems to have been good attention paid to the connection between some diseases and the ABO blood group type. To our knowledge, nostudy has been done todetermine the association between obesity and ABO blood group. To find the prevalence of obesity in medical students and to determine theAims — association between obesity and ABO blood group. A cross sectional study was carried outMaterials and methods — among 745 medical students. Height, weight, waist circumference, hip circumference was measured. BMI and waist —hip ratio was determined. Blood group was determined by slide agglutination method The findings of theResults — present study reported that the most prevalent blood group was B+ whereas the blood group AB was least prevalent. 25.5% of the total study subjects were overweight and 7.2%were obese. Overweight and obesity were more common among students with blood group B. It was also observed that WHR statistically associated with ABO Blood group system. Conclusion — Participants with blood group B+ had higher prevalence of overweight and obesity. ABO Blood group system showed statistically significant association with WHR.
