This study examined the impact of antismoking activities targeting the general population and an advertising campaign targeting smoking during pregnancy on the prevalence of smoking during pregnancy in New South Wales (NSW), Australia.
Monthly prevalence of smoking during pregnancy was calculated using linked health records for all pregnancies resulting in a birth (800 619) in NSW from 2003 to 2011. Segmented regression of interrupted time series data assessed the effects of the extension of the ban on smoking in enclosed public places to include licensed premises (evaluated in combination with the mandating of graphic warnings on cigarette packs), television advertisements targeting smoking in the general population, print and online magazine advertisements targeting smoking during pregnancy and increased tobacco tax. Analyses were conducted for all pregnancies, and for the population stratified by maternal age, parity and socioeconomic status. Further analyses adjusted for the effect of the Baby Bonus maternity payment.
Prevalence of smoking during pregnancy decreased from 2003 to 2011 overall (0.39% per month), and for all strata examined. For pregnancies overall, none of the evaluated initiatives was associated with a change in the trend of smoking during pregnancy. Significant changes associated with increased tobacco tax and the extension of the smoking ban (in combination with graphic warnings) were found in some strata.
The declining prevalence of smoking during pregnancy between 2003 and 2011, while encouraging, does not appear to be directly related to general population antismoking activities or a pregnancy-specific campaign undertaken in this period.
本研究考察了针对普通人群的反吸烟活动和针对怀孕期间吸烟的广告活动对澳大利亚新南威尔士州（NSW）怀孕期间吸烟流行率的影响。
使用 NSW 2003 年至 2011 年所有导致分娩的妊娠（800619 例）的健康记录，每月计算怀孕期间吸烟的流行率。中断时间序列数据的分段回归评估了将禁止在封闭公共场所吸烟的禁令扩大到包括许可场所（与香烟包装上强制使用图形警告结合评估）、针对普通人群的吸烟电视广告、针对怀孕期间吸烟的印刷和在线杂志广告以及提高烟草税的效果。对所有妊娠和按母亲年龄、产次和社会经济地位分层的人群进行了分析。进一步的分析调整了婴儿奖金生育津贴的影响。
2003 年至 2011 年期间，整体上（每月减少 0.39%）和所有检查的人群中，怀孕期间吸烟的流行率均有所下降。对于所有妊娠，评估的举措均与怀孕期间吸烟趋势的变化无关。在某些人群中发现了与增加烟草税和禁烟令扩大（与图形警告相结合）相关的显著变化。
虽然令人鼓舞，但 2003 年至 2011 年间怀孕期间吸烟流行率的下降似乎与普通人群的反吸烟活动或在此期间开展的特定于妊娠的运动没有直接关系。
