This research synthesis sought to determine the magnitude of associations between major personality dimensions and components of diet. A comprehensive literature search identified 49 articles (584 effect sizes; 151,750 participants) that met the inclusion criteria. Pooled mean effects were computed using inverse-variance weighted random effects meta-analysis. Mean effect sizes from 98 separate meta-analyses provided evidence that lower levels of neuroticism, r = -.05 (95% confidence interval, CI [-.09, -.01]), and higher levels of extraversion, r = .07 (95% CI [.03, .11]); openness, r = .13 (95% CI [.07, .18]); agreeableness, r = .07 (95% CI [.04, .11]); and conscientiousness, r = .12 (95% CI [.08, .16]), are associated with a healthier diet. Personality traits related to fruit and vegetable consumption; sugar intake (e.g., candy, sugary drinks); salt intake; consumption of meat, dairy, and fiber; low-fat foods; fast food and snacks; convenience foods; breakfast frequency; meal irregularity; and emotional and restrained eating. There was evidence of publication bias complicating conclusions for conscientiousness and meat eating. Random effects metaregression showed that agreeableness had a stronger positive association with healthy eating among older adults. These findings should be of interest to health care professionals developing health care services that aim to promote healthy eating. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

将大五人格特征与饮食组成部分联系起来：荟萃分析综述。


这项研究综合旨在确定主要人格维度与饮食成分之间的关联程度。全面的文献检索确定了 49 篇符合纳入标准的文章 （584 个效应量;151,750 名参与者）。使用逆方差加权随机效应荟萃分析计算合并均值效应。来自 98 项独立荟萃分析的平均效应量提供了证据表明，较低水平的神经质 r = -.05 （95% 置信区间，CI [-.09， -.01]） ，较高水平的外向性 r = .07 （95% CI [.03， .11]）;开放性，r = .13 （95% CI [.07， .18]）;宜人性，r = .07 （95% CI [.04， .11]）;和尽责性 r = .12 （95% CI [.08， .16]） 与更健康的饮食相关。与水果和蔬菜消费相关的性格特征;糖摄入量（例如糖果、含糖饮料）;盐摄入量;肉类、奶制品和纤维的消费;低脂食物;快餐和小吃;方便食品;早餐频率;膳食不规律;以及情绪化和克制的饮食。有证据表明，发表偏倚使责任心和吃肉的结论复杂化。随机效应元回归显示，宜人性与老年人健康饮食的正相关更强。这些发现应该引起开发旨在促进健康饮食的医疗保健服务的医疗保健专业人员的兴趣。（PsycInfo 数据库记录 （c） 2024 APA，保留所有权利）。
