目的了解空腹血糖受损(IFG)切点下调对糖调节受损(ICR)的影响。方法收集784例完整的健康体检资料并按不同空腹血糖水平分组,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85例,IFG患病率由14.00%增至25.00%,2者比较差异有统计学意义(χ2=88.3,P<0.05),正常糖耐量由57.9%降至46.9%,2者比较差异有统计学意义(χ2=48.2,P<0.05)。空腹血糖5.6~6.0 mmol/L组与<5.6 mmol/L组及与6.1~6.9 mmol/L组比较,在体质量超标或肥胖、高血压、高血脂、脂肪肝及心电图异常方面,差异均有统计学意义(P<0.05)。结论 IFG切点下调后对某高校人群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。 Objective To investigate the effect of impaired fasting glucose (IFG) downregulation on impaired glucose regulation (ICR). Methods A total of 784 cases of healthy physical examination data were collected and grouped according to different fasting blood glucose levels. The data were analyzed by chi-square test. Results After the IFG diagnostic criteria were lowered, the number of cases with IFG increased by 85%, the prevalence of IFG increased from 14.00% to 25.00%, the difference was statistically significant (χ2 = 88.3, ​​P <0.05). The normal glucose tolerance increased from 57.9 % To 46.9%, the difference between the two was statistically significant (χ2 = 48.2, P <0.05). The fasting blood glucose in 5.6-6.0 mmol / L group and <5.6 mmol / L group and 6.1-6.9 mmol / L group were significantly different in body weight or obesity, hypertension, hyperlipidemia, fatty liver and ECG abnormalities Statistical significance (P <0.05). Conclusions The down-regulation of IFG has a significant effect on the IGR distribution in a university population. The newly-added IFG population has abnormal glucose and lipid metabolism, which should be paid more attention and treated as early as possible.
