目标

本研究的目的是确定基线正念饮食、一般正念意识或接受度是否与生活方式改变计划中的短期和长期体重减轻最密切相关。

方法

数据来自参加两阶段试验的 178 名参与者（基线 BMI = 40.9 ± 5.9 kg/m ²，年龄 = 44.2 ± 11.2 岁；87.6% 女性；71.3% 黑人）。所有参与者都参加了最初的 14 周生活方式改变计划，其中包括代餐饮食。然后将初始体重减轻 ≥ 5% ( N = 137) 的参与者随机分配到使用氯卡色林或安慰剂进行 52 周的生活方式改变。线性混合模型检查了正念饮食（正念饮食问卷）和一般正念意识和接受度（费城正念量表）是否预测全样本在第 14 周的短期体重减轻和试验结束时的长期体重减轻。随机参与者的子样本。

结果

在完整样本中，较高的基线接受度预示着较大的短期体重减轻（p = 0.004）。在第 14 周，接受度低 (- 1 SD ) 的人平均减掉 8.7 公斤 ( SE = 0.6) ，而接受度高 (+ 1 SD ) 的人平均减掉11.2 公斤 ( SE = 0.6 )。在第一阶段成功减肥的参与者的子样本中，接受对试验结束时总减重的独立影响没有达到统计学意义（p = 0.058）。正念饮食和一般正念意识都不能独立预测任一时间点的体重减轻。

结论

接受度比一般或饮食特定的生活方式改变减肥意识更强的预测因子。

Mindful Eating, General Mindful Awareness, and Acceptance as Predictors of Weight Loss

Objectives

The goal of the present study was to determine whether baseline mindful eating, general mindful awareness, or acceptance was most strongly associated with short- and long-term weight loss in a lifestyle modification program.

Methods

Data were from 178 participants (baseline BMI = 40.9 ± 5.9 kg/m², age = 44.2 ± 11.2 years; 87.6% female; 71.3% black) who enrolled in a two-phase trial. All participants attended an initial 14-week lifestyle modification program that included a meal replacement diet. Participants who had lost ≥ 5% of initial weight (N = 137) were then randomized to 52 weeks of lifestyle modification with lorcaserin or placebo. Linear mixed models examined whether mindful eating (Mindful Eating Questionnaire) and general mindful awareness and acceptance (Philadelphia Mindfulness Scale) predicted short-term weight loss at week 14 in the full sample and long-term weight loss at the end of the trial in the subsample of randomized participants.

Results

In the full sample, higher baseline acceptance predicted greater short-term weight losses (p = 0.004). At week 14, individuals low in acceptance (− 1SD) lost an average of 8.7 kg (SE = 0.6) compared with 11.2 kg (SE = 0.6) among those high in acceptance (+ 1SD). In the subsample of participants who successfully lost weight in phase 1, the independent effect of acceptance on total losses at the end of the trial did not reach statistical significance (p = 0.058). Neither mindful eating nor general mindful awareness independently predicted weight loss at either time point.
