Abstract:   (941 Views)

          A universal, agreeable criterion for the diagnosis of diabetes has always
   been of interest to the specialists. The suitability of fasting blood sugar (FBS),
   instead of oral glucose tolerance test, due to its simplicity and low cost, has
   always been considered. The purpose of this study was to compare the
   results of fasting blood sugar (FBS) for diagnosing diabetes with those of 2 hr
   postprandial (PP) glucose test advocated by WHO.

          This retrospective study was carried out on 2033 subjects 30 years of age
   and older in Islamshahr who had been selected by step-wise random
   sampling. The subjects comprising 835 males (41%) and 1198 females (59%)
   were studied. FBS and 2 hr PP glucose (75 g glucose administered orally)
   levels were examined and diabetic patients were determined based on the
   WHO criteria. The American Diabetes Association (ADA) criteria were then
   employed and the results of these two systems were compared.

          150 cases (7.4%) out of 2033 subjects, were dubbed diabetic based on
   2hr PP glucose levels of 200 mg/dl and over. On the other hand 119 subjects
   (5.9%) were classified as diabetic taking FBS of 126 mg/dl and higher. Out of
   119 subjects with impaired fasting glucose (IFG) comprising subjects with FBS
   ranging 110-125 mg/dl, 39.5% had normal glucose tolerance test results,
   40.3% were IGT and 20.2% were diabetic. Out of 1795 subjects who were
   classified normal based on the ADA criteria, 24 persons were diabetic and
   198 subjects were IGT.

          Therefore the results show , that the new ADA criterion is unable to
   diagnose a number of diabetic patients and more so with the IGT subjects.
   Based on these findings, FBS measurement is insufficient and GTT is
