Objective To investigate the effect of parental personality on birth outcomes. Design Prospective cohort study. Setting 727 pregnant women and 579 spouses receiving antenatal care at a single-center in rural Tokyo, Japan during 2010–2013. Methods We measured the association between maternal effect of parental personality traits assessed by the Cloninger’s Temperament and Character Inventory on birth outcomes, using multiple regression and adjusting for demographics. Results Maternal self-transcendence personality was inversely associated with gestational age [-0.26 (95% confidence interval (CI): -0.51 to -0.01) weeks per unit] and positively associated with preterm birth [odds ratio (OR) 2.60 (95% CI: 1.00 to 6.75) per unit], while paternal self-transcendence personality was positively associated with gestational age [0.31 (95% CI: 0.07 to 0.55) weeks per unit]. Maternal reward dependence was positively associated with fetal growth [0.30 (95% CI: 0.02 to 0.59) per unit]. Other maternal and paternal personality traits associated with adverse maternal behavior, such as novelty seeking, harm avoidance and self-directedness, were not associated with birth outcomes. Conclusion We found that specific parental personality traits can be associated with birth outcomes.
