BACKGROUND
Identification of weight change patterns may allow tailored interventions to improve long-term weight loss.
PURPOSE
To identify patterns of weight change over 18 months, and assess participant characteristics and intervention adherence factors associated with weight change patterns in a sample of 359 overweight/obese adults.
METHODS
Weight loss (0-6 months) was achieved with reduced energy intake and increased physical activity (PA). Maintenance (7-18 months) provided adequate energy to maintain weight and continued PA.
RESULTS
Latent profile analysis identified three weight change profiles. During weight loss/maintenance, participants in profiles 2 and 3 (18-month weight loss ∼14 %) attended more behavioral sessions and performed more PA compared with profile 1 (18-month weight loss <1 %). Self-efficacy for both weight management and exercise barriers were higher in profiles 2 and 3 compared with profile 1 following weight loss and during maintenance.
CONCLUSION
Weight change patterns can be identified and are associated with both participant characteristics and intervention adherence.
背景
识别体重变化模式可能有助于采取针对性干预措施，以改善长期体重减轻情况。
目的
确定18个月内的体重变化模式，并评估359名超重/肥胖成年人样本中与体重变化模式相关的参与者特征和干预依从性因素。
方法
通过减少能量摄入和增加身体活动（PA）实现体重减轻（0 - 6个月）。维持期（7 - 18个月）提供足够能量以维持体重并持续进行身体活动。
结果
潜在剖面分析确定了三种体重变化剖面。在体重减轻/维持期间，剖面2和剖面3的参与者（18个月体重减轻约14%）比剖面1的参与者（18个月体重减轻<1%）参加了更多行为课程并进行了更多身体活动。在体重减轻后和维持期间，剖面2和剖面3的体重管理自我效能和运动障碍自我效能均高于剖面1。
结论
体重变化模式可以被识别，并且与参与者特征和干预依从性都相关。
