Abstract

Introduction: Many researchers utilize Self-reports to evaluate the prevalence of diseases. However, the accuracy of these Self-reports remains uncertain in various studies. The objective of this particular study was to validate Self-reported cases of Diabetes among adults aged 35-70 years participating in the Shahedieh Cohort Study (SHCS). Methods: This cross-sectional study was conducted using data from the first phase of SHCS during 2015-2017. The study included 1000 Iranian adults aged 35-70 years. The Gold standard for Diabetes was determined by measuring fasting blood sugar (FBS) and evaluating the history of treatment and use of Diabetes medications. To assess Self-report validity, various statistical indices such as sensitivity, specificity, positive and negative predictive values (NPVs), accuracy, positive likelihood ratio (LR+), negative likelihood ratio (LR-) and AUC were used. The Agreement between Self-reported Diabetes and the gold standard was assessed using kappa statistics. All statistical analyses were performed using SPSS version 13 and R 4. 3. 1 software. Results: The study findings indicated that the prevalence of Diabetes was 18% according to Self-report and 19. 9% according to the gold standard measurement. The Self-report accuracy was 95. 67%. There was perfect Agreement (kappa=0. 86) between the Self-report and gold standard criteria. The AUC, sensitivity and specificity of Self-reported Diabetes were 0. 937, 93. 82% and 96. 08%, respectively. Additionally, the results suggested that the Self-report of Diabetes was more valid in individuals with a normal body mass index (BMI) and without a family history of Diabetes in first-degree relatives. Conclusion: The results showed that in the absence of Diabetes control programs, Self-report of Diabetes is reliable and recommended.
