尽管生命早期的身体生长与成年后躯体疾病和心理障碍的风险相关，但很少有研究关注生长与维度人格特征之间的关联。我们研究了出生前和产后身高、体重和体重指数 (BMI) 的生长与成年期五因素模型尺寸之间的关联。在赫尔辛基出生队列研究中，1,682 名参与者完成了 NEO 性格量表 (NEO-PI)，平均年龄为 63 岁。生长估计是根据医疗记录得出的。调整妊娠长度和社会人口统计学变量后，出生体重与神经质呈二次相关。低出生体重的参与者在神经质方面得分最高。出生时较大的体重指数预示着更高的宜人性，而平均体重指数预示着更高的责任心。从出生到成年的体重指数和体重增长轨迹与宜人性和尽责性相关。更具体地说，7 至 11 岁之间和/或 11 岁至成年期间较低的 BMI 和体重增加与较高的责任心和较高的宜人性相关。从出生到成年的身高和体重增长轨迹与外向性相关：出生到6个月期间身高和体重增长较快，7到11岁之间身高增长较慢，11岁到成年之间体重增长较快与较高的外向性相关。对经验的开放与成长无关。这项纵向研究支持产前和产后身体发育与成年期五因素模型人格维度中的 4 个维度之间的关联。
Although physical growth in early life is associated with the risk of somatic illnesses and psychological disorders in adulthood, few studies have focused upon the associations between growth and dimensional personality traits. We examined the associations between pre- and postnatal growth in height, weight, and body mass index (BMI) and Five-Factor Model dimensions in adulthood. From the Helsinki Birth Cohort Study, 1,682 participants completed the NEO Personality Inventory (NEO-PI) at an average age of 63 years. Growth estimates were derived based on medical records. Adjusting for gestational length and sociodemographic variables, birth weight showed a quadratic association with neuroticism; participants with low birth weight scored the highest on neuroticism. Larger ponderal index at birth predicted higher agreeableness, while average ponderal index predicted higher conscientiousness. BMI and weight growth trajectories from birth to adulthood were associated with agreeableness and conscientiousness. More specifically, less BMI and weight gain between 7 and 11 years and/or between 11 years and adulthood were associated with higher conscientiousness and higher agreeableness. Height and weight growth trajectories from birth to adulthood were associated with extraversion: faster height and weight growth between birth and 6 months, slower height growth between 7 and 11 years, and faster weight gain between 11 years and adulthood were associated with higher extraversion. Openness to experience was not associated with growth. This longitudinal study supports an association between pre- and postnatal physical growth and 4 of the Five-Factor Model personality dimensions in adulthood.
