IJCM_116A: Risk assessment of type II Diabetes mellitus using Indian Diabetic Risk Score among adults in a tertiary care hospital, Tamil Nadu - A cross sectional study

Abstract

Background: Non-communicable diseases (NCD) kill 41 million people each year which accounts to 74% of all deaths globally. India ranks second with a diabetes population of 69.2 million and may rise to 123.5 million by 2040. Early detection of diabetes risk through periodic screening could be instrumental in controlling diabetes. Objectives: 1. To estimate the risk of type 2 diabetes mellitus among adults attending tertiary care hospital. 2. To assess correlation between INDIAN DIABETIC RISK SCORE(IDRS) and Random Capillary Blood Sugar (RBS). 1. To assess association between selected risk factors and risk of developing diabetes mellitus. Methodology: This study was done among 270 individuals aged 18 years and above attending NCD OPD in Madurai medical college, Tamil Nadu during November 2023. The sample size was calculated based on 40% global prevalence of moderate to high diabetic risk by Sarah Wild et al. Consecutive sampling was done. After obtaining informed consent, data was collected using semi structured questionnaire containing sociodemographic details, risk factors, and IDRS. Anthropometric measurements and RBS were done. The study excluded all known cases of Diabetes. Results: The mean age of the study participants was 42.25 years (SD 4.70). Majority (83.3%) were females. IDRS categorization showed 18.2%, 56.6% and 25.2% in the low, moderate and high-risk groups respectively. The study indicates moderate correlation (r=0.435) of IDRS and RBS values. Also, significant correlation (r=0.543) of IDRS with RBS in 18-30 age group. Age, waist circumference and body mass index (BMI) were significantly (P < 0.05) higher in the high-risk group. Conclusion: Screening of young adults by simple cost-effective tools like IDRS helps in further evaluation by blood investigations for early detection of diabetes, thereby preventing or delaying complications.
