The relationship between the "Big 5" personality dimensions and body mass index (BMI) were examined in a nationally representative sample (National Health and Resilience in Veterans Study) of male and female U.S. military veterans. Multivariable analyses were conducted to evaluate gender-specific associations between personality factors and BMI. Among male veterans, greater extraversion was associated with higher BMI, (β = 0.18), while lower conscientiousness (β = -0.18), agreeableness (β = -0.18), and emotional stability (β = -0.17) were associated with lower BMI. Among female veterans, only greater consciousness was associated with lower BMI. These associations were robust to effects of age, physical activity, depression, and posttraumatic stress disorder. The "Big 5" personality dimensions are differentially associated with BMI in male and female veterans. While conscientiousness was associated with lower BMI in both male and female veterans, three additional personality dimensions were linked to BMI in male veterans. Implications of these findings for obesity management are discussed.
本研究在一个具有全国代表性的美国退伍军人样本（国家健康和退伍军人韧性研究）中，调查了“大五”人格维度与体重指数（BMI）之间的关系。采用多变量分析评估了人格因素与 BMI 之间的性别特异性关联。在男性退伍军人中，更高的外向性与更高的 BMI 相关（β=0.18），而较低的尽责性（β=-0.18）、宜人性（β=-0.18）和情绪稳定性（β=-0.17）与较低的 BMI 相关。在女性退伍军人中，只有更高的意识与较低的 BMI 相关。这些关联在年龄、身体活动、抑郁和创伤后应激障碍的影响下仍然稳健。“大五”人格维度与男性和女性退伍军人的 BMI 存在差异相关。虽然尽责性与男性和女性退伍军人的较低 BMI 相关，但在男性退伍军人中，另外三个人格维度与 BMI 相关。讨论了这些发现对肥胖管理的意义。
