Prediction of risk of development of type 2 diabetes mellitus using Indian diabetic risk score in rural areas of Hassan

Background It has been estimated by International Diabetic Federation (IDF) that globally as many as 193million people with diabetes, are unaware of their disease, the use of a simple easy to use, non-invasive and cost effective screening tool for community based screening is the need of the hour. This study was taken with objective to assess the risk of development of type 2 diabetes mellitus using Indian diabetic risk score (IDRS), and to determine the association of IDRS with socio-demographic factors.

Methods Cross sectional study was conducted for 3 months in rural areas of Hassan. 480 subjects were chosen by systematic random sampling considering inclusion and exclusion criterions. Data was collected from individuals who were more than 30 years old and not having diabetes. IDRS components were assessed along with other socio demographic components.

Results Out of 480 participants, 256 (53.4%) were females, mean age of the participants 42.38±18.6.  47% belong to class III socioeconomic status, 63%of them are educated, 49% of participants having BMI ≥25, 41% (>0.8) female and 33% (>0.9) male having abnormal waist hip ratio (WHR), 49% of the participants having IDRS score >50 among these high risk participants 35% were having RBS >200. All 24 (100%) morbid obese individuals were having high IDRS score; among these 66.6% have abnormal RBS. IDRS predicted the risk of DM with sensitivity 81% and specificity 59%.

Conclusions As the study finds that percentage random blood glucose is more among participants of high IDRS, thus a simple IDRS tool can be used in the field for mass screening and early intervention.
