A study of postprandial blood sugar level in young medical students.

Prevalence of diabetes was found to be 20.70 per cent and of potential diabetes 6.55 per cent in a survey of tuberculous population of 961 admitted in K. S. Ray Tuberculosis Hospital, Jadavpur, Calcutta, during a year from April, 1975 to March, 1976. The criterion of diabetes was taken to be blood sugar level of 141 mg. percent and above estimated by Folin and Wu method with photo-electric colorimeter, 2 hours after 100 g. of glucose feed, making allowance of 10 mg. per cent only instead of 2030 mg. per cent of non-glucose reducing substance in blood that remains relatively constant. This eliminated the possible variation in sugar intake, and also an approach to true sugar by giving some allowance for non-glucose reducing substance in blood. The potential diabetes was taken to have a blood sugar level of 131-140 mg. per cent. The authors, however, feel that blood sugar level of 151 mg. per cent and above including 30 mg. per cent of saccharoid should be the really acceptable criterion of diagnosing diabetes, and 141-150 mg. per cent of potential diabetes, but this would have been a disadvantage for a comparative study with others. This rnakes the prevalence of diabetes to be 14.46 per cent and potential diabetes 6.24 per cent. The most aged diabetic was of 82 years of age and the youngest was 4 years. Out of 199 cases determined as diabetes by blood sugar level of 141 mg. per cent and above, 93 cases only had sugar in urine. This indicates that 10 cases (11.03 per cent) of genuine diabetics would have been missed if the test for diabetes was limited to urine examination only. On the other had, out of 762 tuberculosis cases who were labelled as non-diabetics according to blood sugar estimation, 38 (3.95 per cent) cases had sugar in urine. These cases who were really cases of renal glycosuria only would be diagnosed as diabetics with all its consequences. A Study of Postprandial Blood Sugar Level in Young Medical Students by S.P.

Estimation of postprandial blood sugar level was done in 122 normal young male and female subjects by Nelson-Somogyi method. An average value of 107.64 mg. per cent
