![]() ![]() BMI was calculated by the formula BMI=weight in kg/height in m 2. Height was measured by the same instrument to the nearest 0.1cm. Stadiometer was employed to check bodyweight in kilograms, with subjects not wearing shoes and in light clothing. Informed written consent containing the objective of study was taken from the participants and complete confidentiality was assured. Study subjects were divided into groups on the basis of their blood group A, B, AB and O. Out of 200 only 192 properly attempted the questionnaire (96% response rate), rest were refused to participate in this study. Relevant information including race, ethnicity, place of residence, age, past medical history and family history were collected by administering a structured questionnaire. Necessary sample size = (z-score) 2 x Standard deviation x (Standard deviation-1) Sample size was calculated using the following formula: A total of 200 students of age 17-25 years of the university were enrolled by convenience sampling. Students from various departments were involved in this study namely Department of Nutrition and Dietetics (DND), Department of Physiotherapy (DPT), Optometry and MBBS. This cross sectional study was performed among the undergraduate students of Faisalabad based institutes during May 2017 to July 2017. Poor eating habits, use of snacks and fast food consumption are leading to obesity in this population 8 which can results in impairment of cognitive functions associated with poor academic performance and grades. The present study was aimed to determine the frequency of obesity and its association with blood groups among university students. New studies are needed to validate the association between blood groups and BMI, as the curiosity in this matter is unabated. ![]() 2, 6 Evidences are also present suggesting the ABO system as a genotype marker for obesity 7 but this relationship is still under intense investigation due to these conflicting results. 4 Several researchers in the past have reported the linkage of obesity with ABO blood groups, 4, 5 while some have also disagreed to this relation. Evidence of correlation between polygenic modes of expression of hypertension, diabetes have been established with ABO genes in mice models, however the exact interlooping of genes is yet to be ascertained as a proper relation is difficult to assess in polygenic expression. Genes for the ABO blood grouping system are located on chromosome 9q34. 3 Due to the continuous rise in prevalence of obesity in Pakistan, it is essential to create awareness among the Pakistani population about harmful effects of obesity and identify the population at risk, so that it may be preventable in the future. 1 Pakistan ranked 9 th out of 133 countries in the global burden of disease as mentioned in a report published in 2014. It is an emerging epidemic in our country involving children as well as adults. It has been associated with poor quality of life due to its psychosocial consequences and reduced life expectancy. It also affects the cognition levels and performance. ![]() 1įinding the predisposing factors of obesity is a major concern for researchers due to its grave consequences like hypertension, hypercholesterolemia, diabetes mellitus type II, myocardial infarction, infertility, obstructive sleep apnoea, 1 osteoarthritis and cancers. ![]() WHO states burden of obesity in urban areas of Pakistan from 22-40%. Obesity is prevalent globally in all age groups at an alarming rate. ![]()
