A key objective of this study was to examine obesity care attitudes and behaviors of people with obesity (PwO) and determine independent factors associated with a self-reported sustained weight loss success outcome.
An online survey was conducted in 2015 among 3008 U.S. adult PwO (BMI > 30 through self-reported height and weight). Multivariate logistic models explained variation in weight loss success, defined as ≥ 10% weight loss in previous 3 years and maintained for > 1 year.
Controlling for weight changes over time, we found significant associations between self-reported weight history and weight loss success. PwO who had personal motivation to lose weight, were willing to talk to a diabetes educator about their weight, who had their weight loss attempts recognized by a healthcare provider, and were diagnosed with "obesity" or "overweight" were more likely to report having success losing weight.
This study does not determine causality, but suggests motivation and engagement with PwO may impact weight loss, and presents a basis for assessing the mechanism involved. Determining such mechanisms may identify important targets to improve obesity treatment outcomes.

本研究的一个主要目标是调查肥胖患者的肥胖症护理态度和行为，并确定与自我报告的持续减重成功结果相关的独立因素。
2015 年，对 3008 名美国成年肥胖患者（BMI 通过自我报告的身高和体重＞30）进行了在线调查。多变量逻辑模型解释了减重成功的变化，定义为在过去 3 年内体重减轻≥10%，并持续>1 年。
控制体重随时间的变化，我们发现自我报告的体重史与减重成功之间存在显著关联。有个人减肥动机、愿意与糖尿病教育者谈论体重、体重减轻尝试得到医疗保健提供者认可、被诊断为“肥胖症”或“超重”的肥胖患者更有可能报告成功减肥。
本研究不能确定因果关系，但表明肥胖患者的动机和参与可能会影响减重效果，并为评估所涉及的机制提供了依据。确定这些机制可能会找到改善肥胖症治疗结果的重要目标。
本研究在 ClinicalTrials.gov 注册，编号为 NCT03223493，https://clinicaltrials.gov/ct2/show/NCT03223493。于 2017 年 7 月 17 日（回溯性注册）。
