Glycosylated Hemoglobin in Different Levels of BMI.

Body mass index is an inexpensive and easy method of screening for weight categories that may lead to health problems. Increased BMI in overweight and obese persons is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus. This Analytical cross sectional study was undertaken to assess the relation between increasing BMI and glycemic control of body through measuring glycosylated hemoglobin. This study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2011 to June 2012 on 180 equally divided male and female persons between the age of 25 to 55 years. Age more than 55 years and less than 25 years and diagnosed case of hypothyroidism, cushing's syndrome, polycystic ovary, antipsychotic drug user and regular steroid users were excluded. Non probability purposive type of sampling technique was used for selecting the study subjects. Measurement of body mass index was done as per procedure. Glycosylated hemoglobin was estimated by Boronate Affinity method. Statistical analysis was done by SPSS (version 17.0). Data were expressed as Mean (±SE) and statistical significance of difference among the groups were calculated by unpaired student's 't' test and Pearson's correlation coefficient tests were done as applicable. There was no significant difference of glycosylated hemoglobin level between control and study groups. But there was positive correlation within each group (r=0.255, 0.37 and 0.39 in control, overweight and obese respectively). The observed positive correlation between BMI and glycosylated hemoglobin emphasizes the maintenance of normal BMI to prevent early onset of type 2 diabetes mellitus. Health education activities highlighting the danger of becoming overweight and obese should be undertaken.
