Abstract

Objective: Given that low early (4 weeks) weight loss (WL) predicts longer-term WL, the purpose of this study was to identify factors associated with poor early WL.

Methods: 438 adults with overweight/obesity participating in an Internet-delivered behavioral WL program provided weights at baseline and 4 weeks. Participants were stratified by percent WL at 4 weeks: LOW: <2% WL, MEDIUM: 2 to <4% WL, HIGH: ≥4% WL and groups were compared on baseline variables (demographics, physical activity, and psychosocial measures) and 4-week intervention adherence.

Results: 37.4%, 40.9%, and 21.7% of participants had LOW, MEDIUM, and HIGH early WL respectively. LOW was more likely to be female compared to HIGH and less likely to be non-Hispanic White compared to MEDIUM and HIGH (p's<0.05). After controlling for demographic differences, LOW had lower baseline physical activity compared to HIGH and watched fewer video lessons, self-monitored calorie intake and weight on fewer days, and were less likely to achieve the exercise goal compared to MEDIUM and HIGH (p's<0.05).

Conclusion: Findings can inform future adaptive interventions which tailor treatment based upon early WL to improve WL outcomes for more individuals.

行为减肥治疗中早期无反应者的特征。

研究目的鉴于早期（4 周）减重率低可预测长期减重率，本研究旨在确定与早期减重率低有关的因素。方法：438 名超重/肥胖成人参加了一项通过互联网提供的行为减重计划，并提供了基线和 4 周时的体重。根据4周时体重减轻百分比对参与者进行分层：低：结果分别有 37.4%、40.9% 和 21.7% 的参与者早期体重为 LOW、MEDIUM 和 HIGH。与 "中度 "和 "高度 "相比，"低度 "参与者中女性的比例更高，非西班牙裔白人的比例更低（P's）：研究结果可为未来的适应性干预措施提供参考，这些干预措施可根据早期 WL 调整治疗方案，以改善更多患者的 WL 结果。
