OBJECTIVES
When experiencing negative mood, people often eat to improve their mood. A learned association between mood and eating may cultivate frequent food cravings, detracting from health goals. Training in mindful eating may target this cycle of emotion-craving-eating by teaching individuals to manage urges when experiencing negative mood. We examined the impact of a mobile mindful eating intervention on the link between negative mood and food cravings among overweight women.
METHODS
In a single-arm trial, participants ( = 64, age = 46.1 years, BMI = 31.5 kg/m) completed ecological momentary assessments of negative mood and food cravings 3 times/day for 3 days pre- and post-intervention, as well as 1-month post-intervention. Using multilevel linear regression, we compared associations between negative mood and food craving strength at pre- vs. post-intervention (model 1) and post-intervention vs. 1-month follow-up (model 2).
RESULTS
In model 1, negative mood interacted with time point ( = - .20, = .09, = .02, 95% CI [- .38, - .03]) to predict craving strength, indicating that the within-person association between negative mood and craving strength was significantly weaker at post-intervention ( = 0.18) relative to pre-intervention ( = 0.38). In model 2, negative mood did not interact with time point to predict craving strength ( = .13, = .09, = .10, 95% CI - .03, .31]); the association did not significantly differ between post-intervention and 1-month follow-up.
CONCLUSIONS
Training in mindful eating weakened the mood-craving association from pre- to post-intervention. The weakened association remained at follow-up. Our findings highlight the mood-craving link as a target-worthy mechanism of mindful eating that should be assessed in clinical trials.

目的
当人们情绪低落时，常常会通过进食来改善情绪。情绪与进食之间形成的习得性关联可能会导致频繁的食物渴望，从而影响健康目标。正念饮食训练或许可以通过教导个体在情绪低落时控制冲动，来打破这种情绪-渴望-进食的循环。我们研究了一项移动正念饮食干预措施对超重女性负面情绪与食物渴望之间联系的影响。
方法
在一项单臂试验中，参与者（n = 64，年龄 = 46.1岁，BMI = 31.5 kg/m²）在干预前3天、干预后3天以及干预后1个月，每天3次完成对负面情绪和食物渴望的生态瞬时评估。我们使用多水平线性回归，比较了干预前与干预后（模型1）以及干预后与1个月随访期（模型2）负面情绪与食物渴望强度之间的关联。
结果
在模型1中，负面情绪与时间点存在交互作用（β = -0.20，SE = 0.09，p = 0.02，95%CI [-0.38, -0.03]）来预测渴望强度，这表明在干预后，个体内部负面情绪与渴望强度之间的关联（β = 0.18）相较于干预前（β = 0.38）显著减弱。在模型2中，负面情绪与时间点不存在交互作用来预测渴望强度（β = 0.13，SE = 0. [09，p = 0.10，95%CI -0.03, 0.31]）；干预后与1个月随访期之间的关联没有显著差异。
结论
正念饮食训练减弱了从干预前到干预后情绪与渴望之间的关联。这种减弱的关联在随访期依然存在。我们的研究结果突出了情绪与渴望之间的联系，作为正念饮食中一个值得在临床试验中评估的有价值的作用机制。
