Background: Impaired fasting glucose (IFG) is a pre-stage to type 2 diabetes mellitus (T2DM) in adults and generally in obese population. In different studies this occurrence varied significantly, but the true prevalence is unknown due to lack of larger representative cohort studies. Authors objectives was to study the prevalence of IFG in different grades of obesity.

Methods: One hundred obese subjects of obesity Grade1 (BMI >25 kg/m2 but <30) and Grade 2 (BMI >30 kg/m2) were studied at Gandhi Medical College, Bhopal from April 2019 to June 2019. Physical examination, blood investigations including fasting blood glucose and oral glucose tolerance test (OGTT) was carried out for all the patients.

Results: Out of 100 subjects, 18(9%) males and 18(9%) females had IFG. Among male subjects highest IFG was recorded in the age group of 60+ years and in the weight rage of 71 to 80 kg. In female subjects, highest prevalence was in the age group 51 to 60 years and in weight range of 51-60 kg. Out of 24 males and 34 female of with Grade 1 obesity, 7% and 10.4% had IFG similarly, out of 25 males and 17 females with grade 2 obesity, 11% and 7.6% had IFG.

Conclusions: IFG is highly prevalent in different grades of obesity. Obesity is the risk factor for the development of diabetes.
