The effects of maternal cigarette smoking during pregnancy on behavioral and physiological measures of arousal were examined in a sample of 50 neonates. After the effects of alcohol, caffeine, and maternal demographic variables were statistically controlled, regression analyses showed that maternal smoking during pregnancy was predictive of higher heart rates overall and during quiet and active sleep. Maternal smoking during pregnancy was also predictive of lower heart rate variability and an increased number of tremors and changes in behavioral state. These findings suggest that maternal cigarette smoking during pregnancy affects the regulation of spontaneous autonomic activity in neonates.
在50名新生儿样本中，研究了孕期母亲吸烟对唤醒行为和生理指标的影响。在对酒精、咖啡因和母亲人口统计学变量的影响进行统计学控制后，回归分析表明，孕期母亲吸烟可预测总体心率较高，以及安静睡眠和活跃睡眠期间的心率较高。孕期母亲吸烟还可预测较低的心率变异性、震颤次数增加以及行为状态变化。这些发现表明，孕期母亲吸烟会影响新生儿自主自发活动的调节。
