A community-based study to assess the sensitivity and specificity of Indian Diabetes Risk Score, among urban Population of District Bareilly, Uttar Pradesh, India

Abstract

Background and objective: Diabetes mellitus is a major public health problem in India and mostly remains unobserved. Indian diabetes risk score (IDRS) is a cost effective and simple tool for screening of undiagnosed diabetic individuals in the community. There is also various socio demographic and anthropometric factors associated with the risk of occurring diabetes. The objectives of the study were to assess the sensitivity and specificity of IDRS method as a screening tool in community as well as to determine the association of IDRS with socio demographic factors.

Material and Methods: This cross sectional study was conducted for a one year period from February 2014 to February 2015 among adults aged 30 years and above residing in select areas of Bareilly City. Simple random sampling technique was adopted to achieve the desired sample size. House to house survey was done for collecting data. Data was tabulated and subjected to statistical analysis.

Results: Out of 640 study subjects, Prevalence of Diabetes Mellitus was found to be 15.2%. Of these, almost half 7.1% were newly diagnosed and 22.7% were found to have high IDRS score. By applying IDRS, at score > 60, 30% sensitivity and 98% specificity was observed. Statistically significant associations of IDRS with age and gender were found. 

Conclusions: This study emphasises on the utilization of Indian diabetes risk score for identifying undiagnosed high risk for patients with diabetes in Indian urban population at community level as it is cost effective.
