压力与肥胖有关。执行功能（Executive Function，EF）是一组行为调节能力，在此关系中起中介作用。参与者是249名完成在线调查的女性。我们使用Cohen的感知压力量表测量压力，使用执行功能行为评定量表（BRIEF）测量EF，使用三因素饮食问卷测量饮食抑制，以及自我报告的BMI。我们使用路径分析对女性的横截面样本来检验我们的假设，即更高的压力与EF降低，更大的无抑制饮食和更高的BMI相关，并测试了压力对无抑制饮食和压力对BMI的间接影响。压力与较低的EF相关（β = 0.53，p <0.001），较低的EF与更大的无节制进食相关（β = 0.34，p <0.001），无节制进食与较高的BMI相关（β = 0.37，p <0.001）。压力通过EF对饮食抑制产生间接影响（β = 0.18，SE = 0.04，p < .001），压力通过EF和饮食抑制对BMI产生间接影响（β = 0.07，SE = 0.02，p < .001）。压力更大的女性可能有更高的BMI，部分原因是EF降低和饮食不受抑制，这表明旨在改善压力管理和EF的干预措施也可能提高体重控制的成功率，至少在这一人群中。
Stress is associated with obesity. Executive Function (EF), a set of behavioral regulation capacities, may play mediating role in this relation if lower EF increases disinhibited eating. Participants were 249 women who completed an online survey. We measured stress using Cohen's Perceived Stress Scale, EF using the Behavior Rating Inventory of Executive Function (BRIEF), disinhibited eating using the Three Factor Eating Questionnaire, and self-reported BMI. We used path analysis on this cross-sectional sample of women to test our hypothesis that higher stress is associated with reduced EF, greater disinhibited eating, and higher BMI and tested the indirect effects from stress to disinhibited eating and from stress to BMI. Stress was related to lower EF (beta = 0.53 p < .001), lower EF was related to greater disinhibited eating (beta = 0.34, p < .001), and disinhibited eating was related to higher BMI (beta = 0.37, p < .001). There was an indirect effect of stress on disinhibited eating through EF (beta = 0.18, SE = 0.04, p < .001) and an indirect effect of stress on BMI through EF and disinhibited eating (beta = 0.07, SE = 0.02, p < .001). Women with higher stress may have higher BMI, in part due to reduced EF and disinhibited eating, suggesting that interventions designed to improve stress management and EF may also improve success with weight control, at least in this population of women.
