Positive Predictive Value of Diabetes Risk Assessment as a Screening Test

Abstract

There is a long asymptomatic duration in which the type 2 diabetes can be diagnosed and a considerable percentage of persons with type 2 diabetes are undetected. So, it is important to evaluate diabetes screening tests. The aim of this study was evaluating risk assessment as a screening test. A cross-sectional study was done in four villages of Ajabshir, one of East Azerbaijan ‘s cities in Iran. The total population of the four villages, namely shiraz, Razyan, Nasna, and Pesyn was 4058. 2370 people were more than 30years old in these villages. Out of 1207 people, who had at least one risk factor, 67 persons were diabetics or prediabetics. The PPV of the risk factor assessment was 5.4%, so the ability of the risk factor assessment to predict individuals with prediabetes and type 2 diabetes was significantly poor.
