Research on personality and adiposity has focused primarily on middle-aged and older adults. The present research sought to (a) replicate these associations in a young adult sample, (b) examine whether sex, race, or ethnicity moderate these associations, and (c) test whether personality is associated with the subjective experience of body weight and discrepancies between perceived and actual weight. Participants (N = 15,669; M(age) = 29; 53% female; ∼40% ethnic/racial minority) from Wave 4 of the National Longitudinal Study of Adolescent Health completed a Five-Factor Model personality measure and reported their weight, height, and perception of weight category (e.g., overweight); trained staff measured participants' height, weight, and waist circumference. Conscientiousness was associated with healthier weight, with a nearly 5 kg difference between the top and bottom quartiles. Neuroticism among women and Extraversion among men were associated with higher adiposity. Neuroticism was also associated with misperceived heavier weight, whereas Extraversion was associated with misperceived taller and leaner. The associations were similar across race/ethnic groups. Personality is associated with objective and subjective adiposity in young adulthood. Although modest, the effects are consistent with life span theories of personality, and the misperceptions are consistent with the conceptual worldviews associated with the traits.
人格与肥胖的研究主要集中在中年和老年人身上。本研究旨在：(a) 在年轻成人样本中复制这些关联；(b) 检验性别、种族或民族是否调节这些关联；(c) 测试人格是否与对体重的主观体验以及感知体重与实际体重之间的差异有关。来自青少年健康纵向研究第四波的参与者（N=15669；M（年龄）=29；53%为女性；约 40%为少数民族/族裔）完成了五因素人格量表，并报告了他们的体重、身高和体重感知类别（如超重）；经过培训的工作人员测量了参与者的身高、体重和腰围。尽责性与更健康的体重相关，在最高和最低四分位数之间存在近 5 公斤的差异。女性的神经质和男性的外向性与更高的肥胖率相关。神经质与体重感知过重有关，而外向性与体重感知过高和过瘦有关。这些关联在不同种族/族裔群体中是相似的。人格与年轻成人的客观和主观肥胖有关。虽然影响较小，但这些效应与人格的寿命理论一致，而这些误解与相关特征的概念世界观一致。
