Background. Measuring success of obesity interventions is critical. Several methods measure weight loss outcomes but there is no consensus on best practices. This systematic review evaluates relevant outcomes (weight loss, BMI, % body fat, and fat mass) to determine which might be the best indicator(s) of success. Methods. Eligible articles described adult weight loss interventions that included diet and physical activity and a measure of weight or BMI change and body composition change. Results. 28 full-text articles met inclusion criteria. Subjects, settings, intervention lengths, and intensities varied. All studies measured body weight (-2.9 to -17.3 kg), 9 studies measured BMI (-1.1 to -5.1 kg/m(2)), 20 studies measured % body fat (-0.7 to -10.2%), and 22 studies measured fat mass (-0.9 to -14.9 kg). All studies found agreement between weight or BMI and body fat mass or body fat % decreases, though there were discrepancies in degree of significance between measures. Conclusions. Nearly all weight or BMI and body composition measures agreed. Since body fat is the most metabolically harmful tissue type, it may be a more meaningful measure of health change. Future studies should consider primarily measuring % body fat, rather than or in addition to weight or BMI.
背景。衡量肥胖干预措施的成效至关重要。有多种方法可测量体重减轻结果，但对于最佳实践尚无共识。本系统评价评估了相关结果（体重减轻、体重指数、体脂百分比和脂肪量），以确定哪些可能是成功的最佳指标。方法。符合条件的文章描述了成人减肥干预措施，包括饮食和体育活动以及体重或体重指数变化和身体成分变化的测量。结果。28篇全文文章符合纳入标准。受试者、环境、干预时长和强度各不相同。所有研究均测量了体重（-2.9至-17.3千克），9项研究测量了体重指数（-1.1至-5.1千克/米²），20项研究测量了体脂百分比（-0.7至-10.2%），22项研究测量了脂肪量（-0.9至-14.9千克）。所有研究均发现体重或体重指数与体脂量或体脂百分比下降之间存在一致性，尽管各测量指标之间在显著性程度上存在差异。结论。几乎所有体重或体重指数与身体成分测量结果均一致。由于体脂是代谢危害最大的组织类型，它可能是衡量健康变化更有意义的指标。未来研究应主要考虑测量体脂百分比，而非体重或体重指数，或除体重或体重指数之外还测量体脂百分比。
