A growing body of evidence has revealed an association between personality traits and obesity, but the findings regarding this association among children remain mixed. The aim of this review was to systematically summarize the literature regarding the associations between personality traits and childhood obesity.
The study has been registered on PROSPERO (CRD42022306529). We searched a total of 8 databases up to July 1, 2023, to identify both published studies and grey literature written in English. Personality traits were classified into five dimensions based on the widely used Five-Factor Model. We conducted random effects meta-analyses to quantitatively synthesize the data. Newcastle-Ottawa Scale was used to assess the quality of included studies.
A total of 7 studies were included. The pooled correlation coefficient of 2 studies was -0.09 (95 % CI: -0.17 to 0.00; I = 0 %) and the pooled standardized mean difference of 3 studies was -0.08 (95 % CI: -0.13 to -0.03; I = 66 %), indicating that conscientiousness was negatively associated with childhood obesity. No consistent patterns were found in the associations between the other 4 dimensions of personality traits and BMI/obesity in children.
Our findings should be interpreted with caution due to the exclusion of non-English studies, the limited generalizability to Eastern population, and the scarcity body of evidence for present topic.
Low conscientiousness has been found to be consistently associated with childhood obesity. Causal associations of personality traits with the risk of childhood obesity remain to be clarified in future studies.
越来越多的证据表明人格特质与肥胖之间存在关联，但关于儿童肥胖与人格特质之间关联的研究结果仍存在差异。本综述旨在系统总结人格特质与儿童肥胖相关的文献。
本研究已在 PROSPERO（CRD42022306529）上注册。我们共检索了 8 个数据库，截至 2023 年 7 月 1 日，以确定发表的研究和英文撰写的灰色文献。人格特质根据广泛使用的五因素模型分为五个维度。我们进行了随机效应荟萃分析来定量综合数据。纽卡斯尔-渥太华量表用于评估纳入研究的质量。
共纳入 7 项研究。2 项研究的合并相关系数为-0.09（95%置信区间：-0.17 至 0.00；I²=0%），3 项研究的合并标准化均数差为-0.08（95%置信区间：-0.13 至 -0.03；I²=66%），表明尽责性与儿童肥胖呈负相关。其他 4 个人格特质维度与儿童 BMI/肥胖之间的关联没有一致的模式。
由于排除了非英语研究、对东亚人群的推广性有限以及现有研究主题的证据有限，我们的发现应谨慎解释。
低尽责性与儿童肥胖存在一致的关联。在未来的研究中，需要进一步阐明人格特质与儿童肥胖风险之间的因果关系。
