空腹血糖水平与体格指数相关关系的分析

目的分析不同空腹血糖水平与体格指数之间的关系，探讨成人空腹血糖受损切点下调的合理性。方法采用分组对照研究，用方差分析及偏相关分析来探讨空腹血糖水平与体格指数之间的关系。结果体重指数、腰围、腰围身高比和腰臀比均随着空腹血糖值升高而升高，特别是血糖值在5．6mmol／L以上时升高更明显。新增空腹血糖受损组与空腹血糖正常组比较，体重指数、腰围、腰围身高比和腰臀比差异有统计学意义（P〈0．05）；新增空腹血糖受损组与传统空腹血糖受损组比较，差异无统计学意义（P〉0．05）。空腹血糖受损与BMI、WC、WHR、WHtR具有显著的正相关关系，腰围身高比的相关系数最大。结论从体格指数方面看，新增空腹血糖受损组与传统空腹血糖受损组具有一致性。降低空腹血糖受损的切点是合理的。

Correlation between fasting plasma glucose and anthropometric measurements

Objective To evaluate the rationale of lowering the cut-point of impaired fasting glucose by studying the correlation between different fasting plasma glucose levels and anthropometric measurements. Methods The investigation used a group control study. The correlation between fasting plasma glucose and antbropometric measurements were evaluated with analysis of variance, partial correlated analysis. Results Tile result showed that body mass index, waist circumference, waist-to-hip rati- o, waist-to-height ratio, increased with the increasing of FPG, especially FPC was 5.6mmol/L and above. The newly categorized impaired fasting glucose group showed increased levels of body mass index, weight circumference, waist/hip ratio, waist/height ratio, as compared to the normal fasting glucose group, there was a significant difference between tile two groups （P 〈 0. 05 ）. The levels of BMI, WC, WHI{, WHtR in tile group of 5.6mmol/L~〈 FPG 〈 6. I mmol/L were not significantly higher than those of group 6. 1mmol/L≤FPG 〈7.0inmol/L （P 〉0. 05）. Impaired fasting glucose was correlated positively with BMI, WC, WHR, WHtR, and the closest correlation was found for WHtR. Conclusion There has the agreement between the group of newly categorized impaired fasting glucose and the group of traditional impaired fasting glucose from amhropometric measurements. It is rational to revise the FPG criterion for diagnosing IFC.
