COMPARISON BETWEEN WHO AND ADA CRITERIA FOR DIAGNOSIS OF DIABETES MELLITUS

To evaluate WHO and ADA criteria for diagnosis of diabetes mellitus . 1606 subjects that referred to Isfahan Endocrine and Metabolism Research Center were examined for oral glucose tolerance test. Blood sugar was examined by enzymatic assay. Sensitivity, specifity , positive and negative predictive value of both criteria were assessed. For WHO criteria, sensitivity of fasting blood sugar was 32% , specifity was 99% , positive predictive value was 65% and negative predictive value was 97%.For ADA criteria , sensitivity of fasting blood sugar was 44%,specificity was,98%,positive predictive value was 51% and negative predictive value was 98%.The sensitivity, specificity, positive and negative predictive values of ADA criteria for IGT diagnosis were 25%, 97.9%, 49% and 94% , respectively. This study suggests that although ADA criteria is more sensitive than WHO criteria for diagnosis of diabetes mellitus, but it is insufficient for screening of this disorder.
