The use of self-report as a strategy for collecting data on women's weight and height is widespread in both clinical practice and epidemiological studies. This study aimed to compare self-reported and directly measured weight and height among women of reproductive age.
In July 2015 we searched MEDLINE, EMBASE, COCHRANE, CINHAL, LILACS and gray literature. We included women of reproductive age (12-49 years old) independently of their weight or height at the time of the study. Women with any condition that implies regular tracking of their weight (for example, eating disorder) were excluded. Two reviewers independently selected, extracted and assessed the risk of bias of the studies. We used REVMAN 5.3 to perform the meta-analysis. Heterogeneity was assessed using the I statistic.
Following eligibility assessment, 21 studies of 18 749 women met the inclusion criteria. The results of the meta-analysis showed an underestimation of weight by -0.94 kg (95% CI -1.17 to -0.71 kg; p < 0.0001; I = 0%) in the overall sample and an overestimation of height by 0.36 cm (95% CI 0.20-0.51; p < 0.0001; I = 35%) based on self-reported vs. directly measured values.
This review shows that self-reported weight and height of women of reproductive age differs slightly from direct measures. We consider that the magnitude at which self-reported data over- or underestimates the real value, is negligible regarding clinical and research use.
在临床实践和流行病学研究中，广泛使用自我报告作为收集女性体重和身高数据的策略。本研究旨在比较育龄妇女自我报告和直接测量的体重和身高。
2015 年 7 月，我们检索了 MEDLINE、EMBASE、COCHRANE、CINHAL、LILACS 和灰色文献。我们纳入了育龄妇女（12-49 岁），无论其在研究时的体重或身高如何。排除任何暗示定期跟踪其体重的疾病（例如，进食障碍）的女性。两名审查员独立选择、提取和评估研究的偏倚风险。我们使用 REVMAN 5.3 进行荟萃分析。使用 I 统计量评估异质性。
经过资格评估，21 项研究共纳入 18749 名女性。荟萃分析结果显示，总体样本中自我报告的体重低估了-0.94kg（95%CI-1.17 至-0.71kg；p<0.0001；I ² =0%），而自我报告与直接测量值相比，身高高估了 0.36cm（95%CI0.20 至 0.51；p<0.0001；I ² =35%）。
本综述表明，育龄妇女自我报告的体重和身高与直接测量值略有不同。我们认为，自我报告数据高估或低估真实值的幅度，在临床和研究应用中可以忽略不计。
