Eat Weight Disord. 2024 Aug 16;29(1):53. doi: 10.1007/s40519-024-01677-1.
Obesity causes many physical and mental illnesses. This study compares mindfulness-based eating awareness training (MB-EAT) versus MB-EAT plus implementation intention model for effectiveness on body mass index (BMI), weight self-efficacy, and physical activity in obese women with BMIs ≤ 25 (n = 52).
In this randomized clinical trial, the participants were selected by the simple random sampling method and randomly divided into three groups. A 12-session MB-EAT of 150 min per session was performed for experimental group I. The experimental group II received MB-EAT alone for physical activity planning and MB-EAT plus implementation intention; also, both groups were compared to the control group. Data were measured by the scales, a questionnaire, and a checklist, and the P-values are based on the results of the generalized estimating equation (GEE) test. P < 0.001 were considered the significance level.
The MB-EAT and MB-EAT + implementation intention effectiveness on the two experimental groups' BMI, weight self-efficacy, and physical activity was significantly different from the control group. In the integrated group versus the MB-EAT group, BMI, physical activity, and physical discomfort, were more effective than the weight self-efficacy subscales. Both intervention groups were effective on BMI, weight self-efficacy, and physical activity, but the integrated group's effectiveness was more.
The MB-EAT effectiveness trial is theory-based, reducing weight and the psychological and behavioral consequences of overweight and obese adults. The MB-EAT + the Implementation intention model is to plan regular and daily exercise according to each individual's specific circumstances.

肥胖会导致许多身心疾病。本研究比较了正念饮食意识训练（MB-EAT）与 MB-EAT 加实施意向模型对 BMI、体重自我效能和身体活动的影响，对象为 BMI≤25 的肥胖女性（n=52）。
在这项随机临床试验中，参与者采用简单随机抽样法选取，并随机分为三组。实验组 I 接受 12 次 150 分钟/次的 MB-EAT。实验组 II 仅接受 MB-EAT 进行身体活动规划，以及 MB-EAT 加实施意向；同时将两组与对照组进行比较。数据通过量表、问卷和检查表进行测量，P 值基于广义估计方程（GEE）检验结果。P<0.001 被认为具有统计学意义。
MB-EAT 和 MB-EAT+实施意向对两组实验组的 BMI、体重自我效能和身体活动均有显著影响，与对照组相比存在显著差异。在整合组与 MB-EAT 组的比较中，BMI、身体活动和身体不适的效果优于体重自我效能子量表。两组干预组对 BMI、体重自我效能和身体活动均有效，但整合组的效果更显著。
MB-EAT 有效性试验基于理论，可减轻体重和超重及肥胖成年人的心理和行为后果。MB-EAT+实施意向模型是根据每个人的具体情况计划定期和日常锻炼。
