空腹血糖受损切点下调后糖调节受损状况调查

目的了解空腹血糖受损（IFG）切点下调后对糖调节受损（IGR）状况的影响。方法收集1896例完整的健康体检资料并分别按年龄和不同空腹血糖水平进行分组，采用卡方检验进行统计学分析。结果IFG诊断标准下调后IFG患病例数增加271例，IFG患病率由13．1％增至27．4％，两者比较差异有统计学意义（Х^2=62．68，P〈0．05），正常糖耐量由60．3％降至47．5％，两者比较差异有统计学意义（Х^2=120．03，P〈0．05）。空腹血糖5．6～6．0mmol／L组与〈5．6mmol／L组及与6．1～6．9mmol／L组比较，在超重或肥胖、高血压、高血脂、脂肪肝及心电图异常方面比较，差异均有统计学意义（P〈0．05）。结论IFG切点下调后对武汉该地区IGR分布有显著影响，新增单纯IFG人群已出现糖、脂代谢异常，应引起重视并及早进行干预治疗。

Effect of lowering the upper limit of normal fasting glucose on the distribution of impaired glucose regulation in the population in Wuhan urban areas

Objective To analyze the effect of lowering the upper limit of normal fasting glucose on the distribution of impaired glucose regulation （IGR） in the population in Wuhan urban area. Methods The health profiles of 1896 people after physical examinations were analyzed by Х^2 test. Results The low limit for impaired fasting glucose （IFG） was decreased from 6. 1 to 5.6 mmol/L, IFG increased 271 patients, the prevalence of IFG increased from 13. 1% to 27.4% （Х^2 = 62.68 ,P 〈 0.05）, and the value of normal glucose test decreased from 60. 3% to 47.5% （ Х^2 = 120. 03, P 〈 0. 05 ）. Overweight or obesity, hypetention, fatty liver, hyperlipidemia, ECG abnormality were significantly different （ P 〈 0. 05 ） in groups of fasting glucose 5.6-6. 0 mmol/L to 〈 5.6 mmol/L and to 6. 1-6. 9 mmol/L. Conclusion The new cut point of IFG has significantly influenced the distribution of IGR in the population of Wuhan urban areas. In the newly IFG- increased subjects, metabolic abnormalities of glucose and lipid occur, and an intervention of life-style is needed for them.
