To describe maternal smoking trends in France between 1972 and 2016, and identify whether maternal characteristics associated with smoking in the 3rd trimester of pregnancy evolved between 2010 and 2016. Using French National Perinatal Surveys, we estimated proportions of smokers and the number of cigarettes smoked both just before pregnancy and during the 3rd trimester from 1972 to 2016. We used a Poisson model with robust variance to estimate prevalence ratios for smoking during pregnancy. Proportions of mothers quitting smoking were relatively stable (46.0% in 1972 and 45.8% in 2016). The number of cigarettes smoked just before pregnancy and in the 3rd trimester decreased from 1995 onward. However, proportions of smokers remained high before (30.1%) and during the 3rd trimester in 2016 (16.2%). Smoking in the 3rd trimester was associated with a lower education level and lower income in both 2010 and 2016, whereas the association with age, country of birth and parity varied according to the survey year. Early targeted interventions are needed for smokers who plan to have a child and must take smokers' characteristics during pregnancy into account.
描述 1972 年至 2016 年法国孕妇吸烟趋势，并确定与妊娠晚期吸烟相关的孕妇特征在 2010 年至 2016 年期间是否发生了变化。利用法国国家围产期调查，我们从 1972 年至 2016 年估计了孕妇在怀孕前和妊娠晚期吸烟的比例和吸烟量。我们使用具有稳健方差的泊松模型来估计怀孕期间吸烟的患病率比。戒烟的孕妇比例相对稳定（1972 年为 46.0%，2016 年为 45.8%）。1995 年以来，怀孕前和妊娠晚期的吸烟量有所减少。然而，2016 年怀孕前（30.1%）和妊娠晚期（16.2%）的吸烟比例仍然很高。在 2010 年和 2016 年，妊娠晚期吸烟与教育程度较低和收入较低有关，而与年龄、出生地和生育次数的关系则因调查年份而异。需要对计划生育的吸烟者进行早期有针对性的干预，必须考虑到孕妇在怀孕期间的吸烟特征。
