The effects of anti-smoking health education during pregnancy on smoking behaviour and the subsequent infant's size at birth were investigated in a controlled trial. It was found that the planned educational intervention was incompletely carried out and was given more effectively to primigravidae in whom subsequent reduction of smoking was more evident. The effects of educative intervention on size at birth were therefore analysed for first and later pregnancies separately. The differences in birthweight and length between the intervention and control groups were concentrated almost entirely among the first born infants who were 68 g heavier and 0.75 cm longer in the intervention group than the first born infants in the control group.
在一项对照试验中，研究了孕期进行的反吸烟健康教育对吸烟行为及随后出生婴儿的出生大小的影响。结果发现，计划的教育干预未得到充分实施，且对初产妇实施得更有效，初产妇随后吸烟减少更为明显。因此，分别对首次怀孕和后续怀孕的情况分析了教育干预对出生大小的影响。干预组和对照组之间出生体重和身长的差异几乎完全集中在头胎婴儿中，干预组的头胎婴儿比对照组的头胎婴儿重68克，长0.75厘米。
