BACKGROUND
Previous US population-based studies have found that body weight may be underestimated when self-reported. However, this research may not apply to all US Hispanics/Latinos, many of whom are immigrants with distinct cultural orientations to ideal body size. We assessed the data quality and accuracy of self-reported weight in a diverse, community-based, US sample of primarily foreign-born Hispanic/Latino adults.
METHODS
Using baseline data (2008-2011) from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), we described the difference between contemporaneous self-reported and measured current body weight (n = 16,119) and used multivariate adjusted models to establish whether the observed trends in misreporting in potential predictors of inaccuracy persisted after adjustment for other predictors. Last, we described the weighted percentage agreement in body mass classification using either self-reported or measured weight (n = 16,110).
RESULTS
Self-reported weight was well correlated with (r = 0.95) and on average 0.23 kg greater than measured weight. The range of this misreporting was large and several factors were associated with misreporting: age group, gender, body mass categories, nativity, study site by background, unit of self-report (kg or lb), and end-digit preference. The percentage agreement of body mass classification using self-reported versus measured weight was 86% and varied across prevalent health conditions.
CONCLUSIONS
The direction of misreporting in self-reported weight, and thus the anticipated bias in obesity prevalence estimates based on self-reported weights, may differ in US Hispanic/Latinos from that found in prior studies. Future investigations using self-reported body weight in US Hispanic/Latinos should consider this information for bias analyses.See video abstract at, http://links.lww.com/EDE/B276.
背景
之前的美国基于人群的研究发现，自我报告的体重可能被低估。然而，这项研究可能不适用于所有美国西班牙裔/拉丁裔，其中许多人是具有独特的理想体型文化取向的移民。我们评估了一个多元化的、基于社区的、主要是外国出生的西班牙裔/拉丁裔成年人群体中自我报告体重的数据质量和准确性。
方法
利用西班牙裔社区健康研究/拉丁裔研究（HCHS/SOL）的基线数据（2008-2011 年），我们描述了同期自我报告和当前测量体重之间的差异（n=16119），并使用多元调整模型来确定在调整其他预测因素后，观察到的不准确报告的趋势在潜在预测因素中是否仍然存在。最后，我们描述了使用自我报告或测量体重进行体重分类的加权百分比一致性（n=16110）。
结果
自我报告的体重与（r=0.95）高度相关，平均比测量体重高 0.23kg。这种报告错误的范围很大，几个因素与报告错误有关：年龄组、性别、体重类别、出生地、研究地点与背景、自我报告的单位（kg 或 lb）以及末位数字偏好。使用自我报告与测量体重进行体重分类的百分比一致性为 86%，并因常见健康状况而异。
结论
自我报告体重中的错误报告方向，以及基于自我报告体重的肥胖患病率估计值的预期偏差，在美国西班牙裔/拉丁裔人群中可能与之前的研究不同。未来在美国西班牙裔/拉丁裔人群中使用自我报告体重进行的研究应该考虑这些信息进行偏差分析。请观看视频摘要，网址为，http://links.lww.com/EDE/B276。
