This study examined the association between prenatal exposure to cigarettes and infant and maternal negative affect. Participants were 115 mother-infant dyads (69 prenatally exposed to cigarettes and 46 nonexposed). Infant and maternal negative affect were both assessed during the neonatal period (2-4 weeks of age) and again at 7 months of infant age. Results indicated that only prenatal exposure to cigarettes predicted infant negative affect. Infants who were prenatally exposed to more cigarettes had higher levels of negative affect at both time points. Furthermore, regression analyses indicated that both infant and maternal negative affect during the neonatal period predicted maternal negative affect at 7 months of age. These results highlight the importance of considering the reciprocal relationship between infant and maternal behavior when examining developmental outcomes among infants prenatally exposed to cigarettes.
本研究考察了孕期接触香烟与母婴消极情绪之间的关联。研究对象为115对母婴二元组(69对孕期接触香烟,46对未接触)。在新生儿期(2至4周龄)以及婴儿7月龄时,分别对婴儿和母亲的消极情绪进行了评估。结果表明,只有孕期接触香烟这一因素可预测婴儿的消极情绪。孕期接触香烟更多的婴儿在两个时间点的消极情绪水平都更高。此外,回归分析表明,新生儿期婴儿和母亲的消极情绪均可预测母亲在7月龄时的消极情绪。这些结果凸显了在研究孕期接触香烟的婴儿的发育结局时,考虑婴儿与母亲行为之间相互关系的重要性。
