In a randomised controlled trial intensive individual anti-smoking advice given in parallel with hospital antenatal care did not influence the outcome of pregnancy. The belief that retardation of fetal growth caused by maternal smoking occurs in late pregnancy is not well based, and the advice may not have been given in time to be effective. Other possible interpretations of the results, that maternal smoking is merely an index of some other factor that retards growth or that those counselled did not reduce their smoking sufficiently to influence outcome, cannot be excluded.
在一项随机对照试验中,与医院产前护理并行提供的强化个体化戒烟建议并未影响妊娠结局。认为母亲吸烟导致的胎儿生长迟缓发生在妊娠晚期的观点缺乏充分依据,而且该建议可能未及时给出以产生效果。结果的其他可能解释,即母亲吸烟仅仅是某些其他导致生长迟缓因素的一个指标,或者接受咨询的人没有充分减少吸烟量以影响结局,不能排除。
