In clinical weight-loss trials, the majority of those who lose weight will regain almost all of it within 5 years, yet there is limited evidence about effective strategies to support weight maintenance. The present study aimed to increase understanding of the experiences of those who have been successful at weight maintenance.
This qualitative study used a phenomenological approach. Semi-structured interviews were undertaken with a purposive sample of 10 participants who had maintained a minimum of 10% weight loss for at least 1 year. Interviews were transcribed and then analysed using a foundational thematic approach based on the Colaizzi method.
Participants believed that a more relaxed approach to weight management with realistic, long-term goals was more appropriate for long-term control. They had a strong reason to lose weight often with a medical trigger and had elicited support to help them. Most described the presence of saboteurs. Participants took personal responsibility for their weight management and were in tune with their nutrition and activity needs. Self-monitoring was a strategy commonly used to support this. They described the lack of positive reinforcement in the maintenance phase as a major difficulty.
This small-scale study provides evidence to suggest the importance of a medical prompt to lose weight; planning for how to manage saboteurs and identifying methods of minimising the impact of a reduction in positive reinforcement. It reinforces the importance of many of the strategies known to support the weight-loss phase.
在临床减肥试验中,大多数减肥的人在 5 年内几乎会全部反弹,然而,关于支持体重维持的有效策略的证据有限。本研究旨在增进对那些成功维持体重的人的经验的了解。
本定性研究采用现象学方法。通过目的性抽样,对 10 名至少成功维持 10%体重减轻 1 年以上的参与者进行了半结构化访谈。对访谈进行转录,然后根据基于科莱兹方法的基础主题方法进行分析。
参与者认为,采用更轻松的方法管理体重,设定现实、长期的目标,更适合长期控制。他们减肥的动力通常来自医学诱因,并获得了帮助他们的支持。大多数人描述了存在破坏因素。参与者对自己的体重管理负责,并了解自己的营养和活动需求。自我监测是支持这一点的常用策略。他们描述了维持阶段缺乏积极强化作为一个主要困难。
这项小规模研究提供了证据,表明减肥的医学提示很重要;规划如何管理破坏因素,并确定减少积极强化影响的方法。它重申了许多已知支持减肥阶段的策略的重要性。
