本研究的目的是确定基线正念饮食，一般正念意识或接受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。数据来自178名参与者（基线BMI=40.9±5.9 kg/m2，年龄=44.2±11.2岁; 87.6%为女性; 71.3%为黑人），他们参加了一项两阶段试验。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，体重减轻≥5%的参与者（N=137）被随机分配至52周的生活方式改变组，使用氯卡色林或安慰剂。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（费城正念量表）是否预测了全样本中第14周的短期体重减轻和随机参与者子样本中试验结束时的长期体重减轻。在整个样本中，较高的基线接受度预示着更大的短期体重减轻（p=.004）。在第14周，接受度低（-1SD）的个体平均减掉8.7 kg（SE=0.6），而接受度高（+1SD）的个体平均减掉11.2 kg（SE=0.6）。在第一阶段成功减肥的参与者的子样本中，在试验结束时接受对总损失的独立影响没有达到统计学显著性（p= 0.058）。无论是正念饮食还是一般的正念意识都不能独立预测在任何一个时间点的体重减轻。接受是一个更强的预测比无论是一般或饮食特定的减肥意识与生活方式的改变。
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. 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. In the full sample, higher baseline acceptance predicted greater short-term weight losses (p=.004). At week 14, individuals low in acceptance (−1SD) lost an average of 8.7 kg (SE=0.6) compared to 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=.058). Neither mindful eating nor general mindful awareness independently predicted weight loss at either time point. Acceptance was a stronger predictor than either general or eating-specific awareness of weight loss with lifestyle modification.
