Association of Abo Blood Group with Gynaecoid Fat Distribution Among Male Residents of Obio Akpor Local Government Area of Rivers State

Gynaecoid fat distribution refers to fat patterns that accumulate around the hips, buttocks and thighs. This fat distribution is less associated with cardiovascular diseases. The aim of the study is determined if there is an association between ABO blood group and gynaecoid fat distribution in males. A total of one hundred and forty males (70 males without gynacoid fats and 70 males with gynaecoid fat) between the ages of 18-65 years were selected for this study. The parameters measured were height, weight, waist circumference, hip circumference, waist-to-hip ratio (WHR), body mass index and blood group using stature meter, weighing scale, inelastic tape and questionnaire respectively. To access if a male has gynaecoid fat distribution both the morphoscopic evaluation of the pelvic and thigh region for the pear shape appearance and WHR was used. The result shows blood group O is the most dominant for both normal males and males with gynaecoid fat (42.8% and 34.28% respectively), follow by blood group A (22.8% and 25.7%). In conclusion, the association between ABO blood group and gynaecoid fat distribution was not significant therefore there is no association between ABO blood group and gynaecoid fat distribution. I recommend that further studies aimed at corroborating this finding should be carried out.
