背景与目的：本研究的目的是评估身体肥胖指数（BAI）作为Xavante印第安人体脂预测指标的有效性，并研究该人群中哪种人体测量肥胖与体脂最相关。方法：974例患者（男性476例），年龄423±19.5岁。采用生物阻抗分析法（BIA）测定体脂率（%BF）作为肥胖的参考指标。采用Bland-Altman分析评估BAI和BIA两种方法之间的一致性。采用Pearson相关分析调查肥胖人体测量指标之间的关联。结果：BAI高估了%BF（平均差值：4.10%），主要是在较低的肥胖水平。BF %与所有测量值之间存在显著相关，其中与BAI的相关性最强。然而，根据性别进行的分层分析显示，男性腰围的相关性最强(r = 0.73, p
Background & aims: The aim of this study was to evaluate the usefulness of Body Adiposity Index (BAI) as a predictor of body fat in Xavante Indians and to investigate which anthropometric measures of adiposity best correlate with body fat in this population.Methods: We evaluated 974 individuals (476 male), aged 423 +/- 19.5 years. Percentage of body fat (%BF) determined by bioimpedance analysis (BIA) was used as the reference measure of adiposity. Bland-Altman analysis was used to assess the agreement between the two methods: BAI and BIA. Associations between anthropometric measures of adiposity were investigated by Pearson correlation analysis.Results: BAI overestimates %BF (mean difference: 4.10%), mainly at lower levels of adiposity. Significant correlations were found between %BF and all measurements, being the strongest correlation with BAI. However, stratified analyses according to gender showed that among men waist circumference has the strongest correlation (r = 0.73, p
