不同标准空腹血糖受损人群葡萄糖负荷后血糖代谢特征

目的：分析两种标准空腹血糖受损人群葡萄糖负荷后血糖代谢特点。方法：对3828名40岁以上居民进行流行病学调查,对空腹血糖≥5.6mmol/L者行75g葡萄糖负荷试验,据不同空腹血糖受损诊断标准分析负荷后2h血糖代谢情况。结果：在以空腹血糖为6.1mmol/L为切点诊断的245例空腹血糖受损（IFG）人群中,糖耐量减低（IGT）的患病率为41.22%,女性（25.71%）高于男性（15.51%）;2型糖尿病（T2DM）患病率为20.82%,女性（11.84%）高于男性（8.98%）。在以空腹血糖为5.6mmol/L为切点诊断的627例空腹血糖受损人群中,糖耐量减低的患病率为37.00%,女性（23.76%）高于男性（13.23%）;2型糖尿病患病率为13.88%,女性（9.52%）高于男性（4.63%）。结论：以空腹血糖为5.6mmol/L和6.1mmol/L为切点诊断的空腹血糖受损人群葡萄糖负荷后2h血糖代谢异常率分别为50.88%和62.04%,患病率女性均高于男性。

Different standards impaired fasting glucose after glucose load glucose metabolism characteristics

Objective：To analyze the metabolism characteristics about blood glucose after glucose load（2hPG） in different impaired fasting glucose populaton（IFG）.Methods：Across-sectional study was conducted on 3 828 residents above 40 years old.The oral glucose tolerance test（OGTT,75 g glucose） was administrated for people whose fasting blood glucose（FPG） ≥5.6 mmol/L.To analyze metabolism characteristics about 2 hPG in different IFG.Results：The prevalence of IGT in IFG（FPG≥6.1 mmol/L） population was 41.22%,it was higher in female（25.71%） than male（15.51%）,The prevalence of T2DM was 20.82%,it was higher in female（11.84%） than male（8.98%）.The prevalence of IGT in IFG（FPG ≥5.6 mmol/L） population was 37%,it was higher in female（23.76%） than male（13.23%）,The prevalence of T2DM was13.88%,it was higher in female（9.52%） than in male（4.63%）.Conclusion：The prevalence of abnormal 2hPG in different IFG population are 50.88% and 62.04%,it is higher in female than male.
