背景：由于一些研究显示出生季节在发病率、自杀行为和脑脊液单胺代谢物方面的变化，我们调查了人群中性格的出生季节变化。方法：采用多元logistic回归分析瑞典于默奥市Betula前瞻性随机队列研究中2130名受试者的气质与性格量表（TCI）。结果：人格维度与年龄、性别显著相关。我们根据年龄、性别和TCI测量季节对数据进行分层。通过每个阶层的中位数分割，得到每个人格维度的高价值组和低价值组。2月至4月出生的人比10月至1月出生的人明显更有可能在女性中具有高NS（追求新奇），特别是NS2子量表（冲动与反思），而在男性中具有高PS（坚持）。气质档案也显示了出生季节的变化。结论：我们讨论了人格与单胺类血清素和多巴胺之间的关系，并建议我们的结果与单胺转换的出生季节变化假设相一致。性格特征可能受到多种遗传和环境因素的影响，其中之一就是出生季节。版权所有(C) 2001 S.

Background: Since several studies show season of birth variations in morbidity, suicidal behavior and CSF (cerebrospinal fluid) monoamine metabolites, we investigated season of birth variations in personality in the population. Methods: We analyzed by multiple logistic regressions the Temperament and Character Inventory (TCI) for 2,130 individuals taking part in the Betula prospective random cohort study of Umea, Sweden. Results: The personality dimensions were correlated significantly with age and gender. We stratified the data according to age, gender and the season of TCI measurement. By the median split in each stratum, a high-value group and a low-value group were obtained for each of the personality dimensions. Those born during February to April were significantly more likely than those born during October to January to have high NS (novelty seeking) among women, particularly the subscale NS2 (impulsiveness vs. reflection), and to have high PS (persistence) among men. Temperament profiles also showed season of birth variations. Conclusions: We discuss the associations in the literature between personality and the monoamines serotonin and dopamine, and suggest that our results are compatible with a hypothesis of season of birth variation in the monoamine turnover. The personality traits are likely to be influenced by several genetic and environmental factors, one of them being the season of birth. Copyright (C) 2001 S. Karger AG, Basel.
