Background: Obesity is a global challenge all over the world. Body mass index is a good marker to measure the adiposity. Obesityis one of the important risk factors for type 2 diabetes mellitus. Normal random blood glucose levels are closely regulated in healthwith a normal range of 4.4-7.8mmol/l (79-140mg/dl), despite the varying demands of food, exercise and fasting. Many diabeticpatients are obese and studies suggest a strong association between the two.Objective: To find an association of BMI with blood glucose level in undergraduate healthy students of Ayub Medical CollegeMaterial and Methods: This cross-sectional study was carried out in 2018, capillary blood samples were collected from 152students of Ayub Medical College Abbottabad to evaluate blood glucose level by Accu chek softclix® lancing device and Accu chekglucometer®, BMI was calculated by the formula (weight in kg/ height in meters squared). Data was collected and analyzed bySPSS version 23.Results: Total 152 (100%) healthy participants with 84 (55.3%) males and 68 (44.7%) females included in this study. Their ageswere ranged from 18-25 with a mean age of 21.02 years (min 17 max 26) having a standard deviation of 1.75. By taking thecorrelation between two parameters i.e. body mass index and serum random blood glucose level by Pearson product of moment(p=.214, r=101) a non-significant result was found.Conclusion: It is concluded that there is no significant association found between two parameters (BMI and serum BGL) in healthyyoung adults.
