新出现的证据表明，气质可以预测生育。我们研究了四种气质特征（新奇寻求，避免伤害，奖励依赖和气质和性格量表的持久性）和生育在生命过程中的人口为基础的心血管风险在年轻的芬兰人研究（n = 1535; 985名女性，550名男性）之间的关联。当参与者年龄在20-35岁时，对气质进行了评估，并且参与者在30-45岁时报告了从青春期到成年的生育史。离散时间生存分析模型表明，低新奇寻求预测高生育概率（标准化OR = 0.92; 95%置信区间0.88-0.97），低伤害避免（OR=0.90; 0.85-0.95）、高奖赏依赖性（OR = 1.09; 1.03-1.15）和低持久性（OR = 0.91; 0.87-0.96），无性别差异或二次效应。这些联系随着孩子数量的增加而变得更强。在一项完全前瞻性分析中，结果基本相同。适应教育并没有影响协会。尽管与总体生育率呈负相关，但高新奇寻求增加了不与伴侣生活在一起的参与者生育子女的概率（OR = 1.29; 1.12-1.49）。这些数据为气质在影响生育方面的作用提供了新的证据，并表明当代人类气质特征可能存在弱自然选择。版权所有（C）2009 John Wiley & Solis，Ltd.
Emerging evidence suggests that temperament may predict childbearing. We examined the association between four temperament traits (novelty seeking, harm avoidance, reward dependence and persistence of the Temperament and Character Inventory) and childbearing over the life course in the population-based Cardiovascular Risk in Young Finns study (n = 1535; 985 women, 550 men). Temperament was assessed when the participants were aged 20-35 and fertility history from adolescence to adulthood was reported by the participants at age 30-45. Discrete-time survival analysis modelling indicated that high childbearing probability was predicted by low novelty seeking (standardized OR = 0.92; 95% confidence interval 0.88-0.97), low harm avoidance (OR=0.90; 0.85-0.95), high reward dependence (OR = 1.09; 1.03-1.15) and low persistence (OR = 0.91; 0.87-0.96) with no sex differences or quadratic effects. These associations grew stronger with in crease in numbers of children. The findings were substantially the same in a completely prospective analysis. Adjusting for education did not influence the associations. Despite its negative association with overall childbearing, high novelly seeking increased the probability of having children in participants who were not living with a partner (OR = 1.29; 1.12-1.49). These data provide novel evidence for the role of temperament in influencing childbearing, and suggest possible weak natural selection of temperament traits in contemporary humans.
