This study sought to understand the process and strategies to recover from regain among weight loss maintainers.
Participants in WeightWatchers (WW; n = 2457) had lost ≥9 kg for ≥1 year and were grouped based on self-reported weight change after maximum loss: sustained maintenance ("Stable"), ups and downs ("Gain-Lose"), and regain ("Gain"). The groups were compared on weight control strategies, and the Gain-Lose and Gain groups reported on attempts to reverse weight regain.
Mean weight loss was 28.5 kg and duration of ≥9 kg loss was 3.5 years. During this time, 48% reported weight stability, and the remaining reported some regain (Gain-Lose, 29% or Gain, 23%). Among Gain and Gain-Lose, action to lose regained weight occurred after gaining >4 kg. Compared with Gain, Gain-Lose sustained reengagement efforts longer (16 vs. 10 weeks) and had better dietary choices (3.4 vs. 3.2), self-monitoring (2.9 vs. 2.7), and psychological coping (2.5 vs. 2.4) scores. Among Gain-Lose, the most successful (< 2.3 kg vs. >2.3 kg regain) initiated weight loss efforts after less regain (2.3 vs. 4.5 kg).
Reengaging with weight loss after regains may be most successful if focused on diet, self-monitoring, and psychological coping and initiated with less regain.
本研究旨在了解体重维持者体重反弹后的恢复过程和策略。
参与 WeightWatchers(WW;n=2457)的参与者已减重≥9kg 且维持≥1 年,根据自我报告的最大减重后体重变化进行分组:持续维持(“稳定”)、波动(“增重-减重”)和反弹(“增重”)。比较各组的体重控制策略,以及“增重-减重”和“增重”组报告的逆转体重反弹的尝试。
平均减重 28.5kg,≥9kg 的减重持续时间为 3.5 年。在此期间,48%的人报告体重稳定,其余人报告体重有一定反弹(“增重-减重”组占 29%,“增重”组占 23%)。在“增重”和“增重-减重”组中,在增重>4kg 后才采取行动来减轻已增重的体重。与“增重”相比,“增重-减重”组的重新参与努力持续时间更长(16 周 vs. 10 周),且饮食选择更好(3.4 分 vs. 3.2 分)、自我监测(2.9 分 vs. 2.7 分)和心理应对(2.5 分 vs. 2.4 分)得分更高。在“增重-减重”组中,最成功的(<2.3kg 比>2.3kg 体重反弹)患者在体重反弹较少(2.3kg 比 4.5kg)后才开始减肥。
如果关注饮食、自我监测和心理应对,且在体重反弹较少时开始重新参与减肥,那么在体重反弹后重新参与减肥可能会更成功。
