目的：探讨正常出生胎龄(37-41周)与3个月大婴儿气质和健康的关系。方法：研究对象为242名无慢性病或严重妊娠并发症的低风险母婴。婴儿气质由三个结构定义：消极情感(NA)、外向和调节，通过父母对婴儿行为问卷的报告进行评估。婴儿健康被定义为婴儿出生后出院后非常规医生就诊的次数。分析使用连续的GA测量来评估GAS的结果，并使用分类测量(37、38、39-41周GA)来检查对比。结果：外向与GA正相关，主要是因为37周出生的婴儿的得分低于39-41周出生的婴儿。NA也表现出类似的作用。37周出生的婴儿接受非常规医疗检查的几率是足月出生的婴儿的2.8倍。讨论：与39-41周出生的婴儿相比，37周出生的婴儿表现出更少的影响和更多的非常规医疗服务。这些发现强调了考虑妊娠延长的风险和与早产相关的发育风险的重要性。
Objective:To examine the association between gestational age (GA) at birth across the normal GA spectrum (37–41 weeks) and the temperament and health of 3-month old infants.Methods:The sample comprised 242 “low-risk” mothers and infants without chronic illnesses or severe pregnancy complications. Infant temperament was defined by three constructs: Negative Affectivity (NA), Extraversion, and Regulation, assessed by parents’ reports on the Infant Behavior Questionnaire. Infants’ health was defined as the number of nonroutine doctors’ visits attended by the infants since their release from the hospital after birth. Analyses employed a continuous measure of GA to assess outcomes across GAs and a categorical measure (37, 38, 39–41 weeks GA) to examine contrasts.Results:Extraversion was positively related to GA primarily due to thelowerscores of infants born at 37 weeks compared to infants born at 39–41 weeks GA. NA showed a similar effect. The odds of infants born at 37 weeks attending a nonroutine medical visit were 2.8 times that of infants born full-term.Discussion:Infants born at 37 weeks GA express less affect and use more nonroutine medical services than do infants born at 39–41 weeks GA. The findings underscore the importance of considering the risks of pregnancy prolongation with the developmental risk associated with early-term delivery.
