本研究的目的是调查身体肥胖指数（BAI）的准确性，作为一个方便的工具，评估身体脂肪百分比（BF%）的超重/肥胖的成年人样本使用生物电阻抗分析（BIA）。研究人群由96名志愿者组成（60%为女性，平均年龄40.6 ± 7.5岁）。评估人体测量特征（体重指数、身高、腰高比、臀围和腰围）、社会经济状况和饮食，并通过BIA-BF%和BAI-BF%测量BF%。Pearson相关系数用于评价BAI-BF%和通过BIA-BF%评估的BF%之间的相关性，同时控制潜在混杂因素。通过配对样本t检验、Lin一致性相关系数和Bland-Altman图分析获得了两种方法测量的BF%之间的一致性。总体而言，在调整潜在混杂因素（年龄、社会经济地位和饮食）后，通过BIA-BF %获得的BF%与通过BAI-BF%估计的BF %之间的相关性为r = 0.885，p < 0.001。Lin的一致性相关系数在两种性别中均为中等。在男性中，配对t检验显示两种方法之间BF%的平均差异显著（-5.6（95%CI-6.4 to-4.8）; p < 0.001）。在女性中，这些差异为（-3.6（95%CI-4.7至-2.5）; p < 0.001）。总体而言，BAI-BF%的偏倚为−4.8 ± 3.2 BF%; p < 0.001），表明与参考方法相比，BAI-BF%方法显著低估了BF%。在超重/肥胖的成年人中，BAI与BIA-BF%测量的BF%的一致性较低;因此，我们得出结论，当体脂百分比水平较低或较高时，BIA-BF%在两种性别中均不准确。需要进一步的研究来证实我们在不同种族群体中的发现。
The aim of this study is to investigate the accuracy of body adiposity index (BAI) as a convenient tool for assessing body fat percentage (BF%) in a sample of adults with overweight/obesity using bioelectrical impedance analysis (BIA). The study population was composed of 96 volunteers (60% female, mean age 40.6 ± 7.5 years old). Anthropometric characteristics (body mass index, height, waist-to-height ratio, hip and waist circumference), socioeconomic status, and diet were assessed, and BF% was measured by BIA-BF% and by BAI-BF%. Pearson’s correlation coefficient was used to evaluate the correlation between BAI-BF% and BF% assessed by BIA-BF%, while controlling for potential confounders. The concordance between the BF% measured by both methods was obtained with a paired sample t-test, Lin’s concordance correlation coefficient, and Bland-Altman plot analysis. Overall, the correlation between BF% obtained by BIA-BF% and estimated by BAI-BF% was r = 0.885, p < 0.001, after adjusting for potential confounders (age, socioeconomic status, and diet). Lin’s concordance correlation coefficient was moderate in both sexes. In the men, the paired t-test showed a significant mean difference in BF% between the methods (−5.6 (95% CI −6.4 to −4.8); p < 0.001). In the women, these differences were (−3.6 (95% CI −4.7 to −2.5); p < 0.001). Overall, the bias of the BAI-BF% was −4.8 ± 3.2 BF%; p < 0.001), indicating that the BAI-BF% method significantly underestimated the BF% in comparison with the reference method. In adults with overweight/obesity, the BAI presents low agreement with BF% measured by BIA-BF%; therefore, we conclude that BIA-BF% is not accurate in either sex when body fat percentage levels are low or high. Further studies are necessary to confirm our findings in different ethnic groups.
