The aim of this study was to validate noninvasive models, retrieved from the literature, estimating body fat in white women. The cohort used for the validation consisted of 277 postmenopausal women, and the reference method was dual-energy X-ray absorptiometry (DXA). Five models were retrieved containing anthropometric measurements such as bicep and tricep skinfolds, waist circumference (WC), height, and body weight. Models including only BMI were found to be less biased and more valid than others including skinfolds and circumferences. The model by Visser et al., estimating body density (BD = 0.0226 × sex - 0.0022 × BMI + 1.0605) with the subsequent use of Brozek's (and not Siri's) equation to estimate body fat percentage (%BF), was found to be more valid than the other models for this cohort. In conclusion, it seems that Visser's et al. model, including only BMI, with Brozek's equation, is a fast, noninvasive, and valid method to assess body composition in white postmenopausal women in clinical practice and research.
本研究旨在验证从文献中检索到的非侵入性模型，以估计白人女性的体脂肪。验证所用的队列包括 277 名绝经后妇女，参考方法是双能 X 射线吸收法（DXA）。检索到的 5 个模型包含人体测量学测量值，如二头肌和三头肌皮褶、腰围（WC）、身高和体重。仅包含 BMI 的模型比包含皮褶和周长的其他模型具有更小的偏差和更高的准确性。Visser 等人的模型，估计体密度（BD=0.0226×性别-0.0022×BMI+1.0605），随后使用 Brozek 的（而不是 Siri 的）方程来估计体脂肪百分比（%BF），对于这个队列来说，比其他模型更准确。总之，似乎只包含 BMI 的 Visser 等人的模型，结合 Brozek 的方程，是一种快速、非侵入性和有效的方法，可在临床实践和研究中评估白人绝经后妇女的身体成分。
