Temperament and sleep in infants are related but also distinct concepts. The longitudinal effects of temperament on sleep in infancy remain unclear, although this information is potentially important for the prevention and treatment of early sleep problems. We examined how various temperament features influence sleep development during the first year of life in a large birth cohort. This study comprised mother-infant dyads with complete longitudinal data on sleep, temperament and sociodemographic measurements at six and 12 months (N = 1436). We observed that higher infant Negative Affectivity was related to several sleep problems, and that many subscales of Negative Affectivity and Orienting/Regulation predicted worse sleep and deterioration in sleep problems from six to 12 months. Few associations between Surgency and sleep were found. Our findings highlight especially Negative Affectivity as a risk factor for persistent and increasing sleep problems, and also the specific importance of the fine-grained aspects of temperament in predicting infant sleep development.
气质和婴儿睡眠是相关但又不同的概念。气质对婴儿期睡眠的纵向影响尚不清楚，尽管这些信息对于预防和治疗早期睡眠问题可能很重要。我们研究了在一个大型出生队列中，各种气质特征如何影响婴儿在生命的第一年中的睡眠发展。这项研究包括母婴对子，他们在 6 个月和 12 个月时具有完整的睡眠、气质和社会人口学测量的纵向数据（N=1436）。我们发现，婴儿的负性情绪与多种睡眠问题有关，而且负性情绪和定向/调节的许多子量表预测了从 6 个月到 12 个月睡眠较差和睡眠问题恶化。在婴儿的机敏性和睡眠之间发现的关联很少。我们的研究结果突出了负性情绪作为持续和增加睡眠问题的风险因素的重要性，以及气质的精细方面在预测婴儿睡眠发展方面的具体重要性。
