Abstract
Background: The prevalence of Diabetes Mellitus is growing rapidly worldwide and is reaching epidemic proportions. Globally around 366 million people have Diabetes in 2011 and by 2030 this will have risen to 552 million. IDRS is a cost effective & simple method for identifying undiagnosed diabetic subject at community level. Objectives: To estimate prevalence of Diabetes Mellitus and to identify high risk subjects by using Indian diabetes risk score for detecting undiagnosed Diabetes in urban and rural areas of Lucknow. Material and Methods: It was a community based cross-sectional study done in the urban and rural areas of Lucknow, under Department of Community Medicine, Era’s Lucknow Medical College and Hospital in subjects aged 20 years and above from August 2013-July 2014. Results and Observations: 555 (67.7%) of subjects were in moderate risk IDRS category while 143 (17.4%) were in low risk and only 122 (14.9%) were in high risk IDRS category. Prevalence of Diabetes Mellitus was highest in high risk IDRS category (47.5%) followed by moderate risk (9.2%) and low risk (2.8%) IDRS category. The sensitivity of IDRS was 81.40% in the present study and a high specificity of 72.0%. Present study also showed a Positive Predictive value of IDRS as 31.7% and a Diagnostic accuracy of 73.3%. Conclusion: This study provides a use of Indian Diabetes Risk Score for identifying undiagnosed high risk for patients with Diabetes in Indian population. It is essential to implement the simple IDRS tool in the community for mass screening so that proper intervention can be carried out to reduce the burden of Diabetes.
