目的探讨不同性别、民族人群体质量指数(BMI)与体脂百分比(PBF)之间的相关关系及两个指标对于肥胖症诊断的价值。方法对925例汉族和维吾尔族健康成年人进行体格检查,通过使用生物电阻抗技术测得体质量和PBF,计算BMI,分析不同民族、性别人群中BMI与PBF间的相关关系。结果在BMI分型为正常和超重的人群中,汉族男性PBF均高于维吾尔族男性PBF(P<0.05);偏瘦、超重和肥胖的汉族女性PBF均高于维吾尔族女性(P<0.05)。不同性别、民族的人群中PBF与BMI均呈正相关(P<0.05)。以BMI≥28kg/m2为诊断肥胖的金标准,两个民族人群采用PBF诊断肥胖均有良好的灵敏度及较低的特异度。结论在相同的BMI分型中,汉族的PBF普遍高于维吾尔族。BMI和PBF对于肥胖的诊断存在一定的不均衡性,评价肥胖不能单纯依靠BMI,可与PBF相结合。
Objective To explore the relationship between body mass index (BMI) and body fat percentage (PBF) in different sexes and ethnic groups and the value of the two indexes in the diagnosis of obesity. Methods The physical examination of 925 Han and Uygur healthy adults was performed. The body mass and PBF were measured by bioelectrical impedance technique. The BMI was calculated and the relationship between BMI and PBF in different ethnic and gender groups was analyzed. Results The PBF of Han males was higher than that of Uyghur males (P <0.05). The PBF of Han women with lean, overweight and obesity was higher than that of Uyghur women (P <0.05) . There was a positive correlation between PBF and BMI in different gender and ethnic groups (P <0.05). To BMI ≥ 28kg / m2 as the gold standard for diagnosis of obesity, the two ethnic groups using PBF to diagnose obesity have good sensitivity and low specificity. Conclusions In the same BMI classification, Han PBFs are generally higher than Uyghur. BMI and PBF for the diagnosis of obesity there is a certain imbalance in the evaluation of obesity can not rely solely on BMI, can be combined with the PBF.
