Little research has taken individual variability in weight loss into account. Furthermore, physical activity (PA) and eating style (ES) have been linked only sporadically to weight loss longitudinally.
Identify and describe latent classes of weight loss, change of PA, and change of ES up to 5 years after surgery and investigate whether these trajectories are interrelated.
Multicenter outpatient clinic.
This is a retrospective study of data collected during standard treatment before and up to 5 years after surgery. Latent class growth analysis was used to identify trajectories of weight loss (percent total weight loss), PA (Baecke questionnaire), and ES (Dutch Eating Behavior Questionnaire).
A total of 2785 patients were included. Follow-up rate was 84% at 1 year and 34% at 5 years. Analyses revealed 5 weight loss trajectories. Most patients followed an average, fairly stable weight loss trajectory (48%) or an above-average partial-regain trajectory (36%). Other patients followed a low-responder trajectory (9%), a rapid weight loss and weight regain trajectory (6%), or a continued weight loss trajectory (2%). Patients in the most favorable weight loss trajectory were more likely to also follow the most favorable ES trajectories. Patients following the most unfavorable weight loss trajectory were never also in the PA trajectory with an initial great increase in PA.
This study distinguishes demographic and behavioral factors that may influence long-term weight loss trajectories after bariatric surgery. Trajectories varied mainly in magnitude and less in the pattern of weight loss over time, suggesting that very deviant patterns are rare.
很少有研究考虑到减肥过程中的个体差异。此外，体力活动（PA）和饮食方式（ES）与减肥的纵向关系也只是偶尔相关。
确定并描述手术后 5 年内体重减轻、PA 变化和 ES 变化的潜在类别，并研究这些轨迹是否相互关联。
多中心门诊。
这是一项回顾性研究，数据来自手术前和手术后 5 年内的标准治疗期间收集的数据。使用潜在类别增长分析来识别体重减轻（总体重减轻百分比）、PA（贝克问卷）和 ES（荷兰饮食行为问卷）的轨迹。
共纳入 2785 例患者。1 年时的随访率为 84%，5 年时的随访率为 34%。分析显示有 5 种体重减轻轨迹。大多数患者遵循平均、相当稳定的体重减轻轨迹（48%）或高于平均的部分恢复轨迹（36%）。其他患者遵循低反应者轨迹（9%）、快速减肥和体重恢复轨迹（6%）或持续减肥轨迹（2%）。处于最有利减肥轨迹的患者更有可能遵循最有利的 ES 轨迹。处于最不利减肥轨迹的患者从未处于 PA 轨迹，初始 PA 大幅增加。
本研究区分了人口统计学和行为因素，这些因素可能会影响减重手术后的长期减肥轨迹。轨迹主要在幅度上有所不同，而在随时间变化的体重减轻模式上则有所不同，这表明非常异常的模式很少见。
