生物电阻抗法测定身体脂肪率在社区2型糖尿病肥胖患者筛查中的应用

Body fat ratio based on bioelectrical impedance method applied in screening obesity in community diabetic patients

摘要

摘要:
目的评价生物电阻抗法测定身体脂肪率(body fat ratio, BFR)在筛查社区糖尿病肥胖患者与BMI判定的一致性。
方法采用生物电阻抗法测定472名社区糖尿病患者BFR，同时测定其身高和体重，计算BMI，采用ROC曲线判定BFR的准确性和有效性。
结果社区472名糖尿病患者肥胖率为14.8%，超重率为41.5%；男性与女性BMI差异无统计学意义(P>0.05)。全人群BFR判定肥胖与BMI的一致性Kappa=0.206，女性BFR判定肥胖与BMI一致性Kappa=0.469。利用ROC曲线对BFR进行评价后发现，在全人群中，BFR判定糖尿病患者肥胖、超重、正常及低体重一致性效果一般；对女性进行ROC曲线评价后，BFR判定女性糖尿病患者肥胖、超重、正常及低体重一致性较好。
结论社区糖尿病患者肥胖患病率及体脂率均较高，体脂率判定女性糖尿病患者肥胖与BMI一致性较好。

Abstract:
ObjectiveTo evaluate the consistency between(body fat ratio, BFR) and(body mass index, BMI) in the determination of obesity.
MethodsThe bioelectrical impedance method was used to determine the BFR in 472 community-based diabetics.BMI was calculated by height and weight.The accuracy and validity of the BFR were evaluated by ROC curves.
ResultsThe prevalence of obesity and overweight was 14.8% and 41.5% respectively.There was no statistical difference found in BMI between male and female.The Kappa Value for the whole population was 0.206, while the Kappa Value for female diabetics was 0.469.Seeing from ROC curve, it was found that in the whole population, BFR did not have well consistency with BMI.In the female population, BFR had good consistency with BMI.
ConclusionThe prevalence of obesity and BFR are high in diabetes patients.The BFR is consistent with BMI in women with diabetes.
