Assessing Diabetes Risk Profiling: An Opportunistic Screening at a Tertiary Care Centre in Krishnagiri, Tamil Nadu, India: A Facility Based Study

Abstract Introduction: The Indian Diabetes Risk Score (IDRS) is a simple, non-invasive tool for identifying the individuals at risk. This study assessed the diabetes risk profile of adults using IDRS and estimated the diabetes yield ratio amongst the study participants at a tertiary care centre in Tamil Nadu. Materials and Methods: Facility based study was conducted amongst 400 adults (≥18 years) accompanying patients at a tertiary care hospital, selected through systematic random sampling. Data were collected using the IDRS questionnaire and anthropometric measurements were taken. The manuscript was prepared in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Results: Based on IDRS, 40.0% were high risk, 47.3% medium risk and 12.8% low risk. Amongst those tested, 13.2% of high-risk and 1.4% of medium-risk individuals were diagnosed with diabetes. A significant association was found between diabetes risk and factors such as gender, education, occupation and body mass index. Conclusion: Opportunistic screening using IDRS effectively identified high-risk individuals, supporting its use for early detection and lifestyle intervention to reduce the diabetes burden.
