Introduction Hypertension is one of the major health problem in the world. There are many factors like family history to life style are related with hypertension. This study was performed to find out the association of hypertension, ABO blood groups and obesity. Aim and objective To find out the relation of hypertension with blood group in medical students of Kathmandu Medical College. Methods This is a prospective study done in department of Physiology. Total participants were 340. ABO blood group was determined by antigen- antibody reaction. Blood pressure was measured two times by standard mercury sphygmomanometer and mean was calculated for accuracy. Height and weight of students were measured by weight scale and measuring tape to calculate BMI (Body Mass Index). Results In total, 167 (49.1 %) were male and 173 (50.9 %) were female. Mean age of students were 20.13. Maximum 112 (32.9 %) had blood group O. In total, 333 students had Rh-+ blood group and 7 had negative. Maximum obesity (30) was found in students with blood group B about 4 (1.17 %). No obesity in students with blood group AB. Prehypertension is most common 77 (22.64 %) in students with normal BMI. But, stage 2 hypertension was common 7 (2.1 %) in pre-obese students. Blood group B was more susceptible with prehypertension and hypertension. Conclusions Blood group B were more susceptible for both prehypertension and hypertension. Prehypertension was seen in maximum with normal BMI students. But stage 2 hypertension was most common in pre-obese. There was highly significant relation of obesity and hypertension (P=0.00)
