Relationship of ABO Blood Groups with Body Mass Index and Hypertension in Medical Students

Abstract

Objective: To find out the relationship of hypertension (HTN), ABO blood groups and body mass
index (BMI) in medical students of Continental Medical college, Lahore.
Methods: This is a prospective study done in department of Physiology. Total participants were
300. ABO blood group was determined by antigen- antibody reaction. Blood pressure (BP) was
measured two times by standard mercury sphygmomanometer and mean was calculated. Height
and weight of students were measured to calculate BMI.
Results: In total 164(55%) were females and 136(45%) were males and mean age was 19 ±
0.75 years (17-23 years). Most prevalent students were of blood group B i.e.101 (34%).
Maximum obese students (≥30 BMI) were belonging to blood group B i.e 18 (6%) and minimum
number of obese students were of blood group AB i.e 4(1%). Blood group B has maximum
prehypertensive (52 or 16.2%) and stage1 hypertensive students (3 or 16.2%) and blood group
AB have minimum prehypertensive(7 or 2%) and no stage-1 hypertensive students.
Conclusions: Blood group-B students were most prevalent and more prone to high BMI and
prehypertension in given population.
