Abstract:
Objective To investigate the prevalence rates of diabetes, impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and related factors in the university staff. Methods 617 subjects were selected from 1 519 cases with the fasting blood glucose level ≥5.6 mmol / L in the annually physical examination among 3 851 population in a university community. All 617 subjects were taken the blood glucose and insulin test for the fasting and 2 hour after 75 g glucose intake. The fasting lipids, BUN and Cr were determined. The demographic data including height, weight, waist circumference and blood pressure was also collected. Results The numbers of normal glucose tolerance (NGT), IFG, IGT, IFG+IGT and newly diagnosed DM were confirmed in 374 (60.62%), 60 (9.72%), 59 (9.56%), 41 (6.65%) and 83 (13.45%); totally, 243 (39.38%) cases with abnormal glucose metabolism. The highest DM prevalence was found in the group with BMI ≥28 kg / m2. In the group with hypertriglyceridemia, prevalence of DM, IFG and IFG +IGT was 12.50%, 8.33% and 8.33%. In the group with hypercholesteremia and hypertriglyceridemia together, prevalence of DM, IFG+IGT, IFG and IGT was 18.87%, 7.17%, 11.32% and 12.83%. DM prevalence increased with the higher triglycerides level. No differences of HOMA-IR was found among groups of DM (0.80?0.82), IFG (0.64?0.72), IFG+IGT (0.61?0.77), IGT (0.35?0.68), but all these obviously higher than that of NGT group (0.17?0.80). No differences of HOMA-B among the IGT (3.97?0.69), NGT (3.95?0.78), IFG (3.84?0.72), IFG+IGT (3.80?0.78) groups, but all these higher than that of NGT(3.69?0.88)group. Conclusion About 40% of these subjects in the university population had their blood glucose ≥5.6 mmol/L. In these subjects with blood glucose ≥5.6 mmol/L, about 40% of them had abnormal blood glucose level, including 13.45% diabetic patients. The highest prevalence of IFG, IGT, IFG+IGT was found in the group aged 60～70, the highest prevalence of DM in the group aged 70～80 and increased paralleled with the BMI and aging, was associated with lipids disorder, particularly with hypertriglyceridemia. IR existed in the pre-diabetes state and was worst in the DM, with most severe ? cell function failure.
