abstract: 'BackgroundMaternal smoking is still a major public health problem posing

  the risk of several negative health outcomes for both the pregnant woman

  and her offspring. The prevalence of maternal smoking in Denmark and

  other high-income countries has decreased continuously since the 1980s,

  and a prevalence below 10\% of women who continue to smoke during

  pregnancy has been reported in studies after 2010. Previous studies have

  shown that low socioeconomic status is associated with maternal smoking.

  Information from the Danish Birth Register about maternal smoking shows

  that the prevalence of women who report to smoke in pregnancy has

  decreased continuously with 23.3\% who reported ever smoking in

  pregnancy in 2000, 12.9\% in 2010 and 9.0\% in 2017. The aim of this

  study was to estimate the prevalence of maternal smoking at the time of

  conception and at 20weeks of gestation in a regional Danish population,

  to describe differences in maternal characteristics among smokers,

  quitters and never-smokers, and to estimate predictors of smoking at the

  time of conception.MethodsA cross-sectional study was conducted among

  pregnant women receiving antenatal care at the Department of Obstetrics,

  Zealand University Hospital, Denmark from August 2015 to March 2016

  (n=566). The main outcome was smoking at the time of conception and at

  20weeks of gestation. The questionnaire also collected information about

  maternal, health-related and sociodemographic characteristics.

  Descriptive analysis was conducted, and multivariate logistic regression

  analysis was used to assess the potential associated predictors

  (adjusted odds ratio).ResultsThe prevalence of self-reported smoking at

  the time of conception was 16\% (n=90) and 6\% smoked at 20weeks of

  gestation (n=35), as 61\% of smokers quit smoking during early

  pregnancy. Multiple logistic regression analysis showed that significant

  predictors for smoking at conception were the socioeconomic factors;

  12years of education, shift work and being unemployed.ConclusionThe

  prevalence of self-reported maternal smoking in this regional Danish

  population of pregnant women is lower than seen in previous studies.

  However, predictors for smoking at the time of conception remain to be

  factors of low socioeconomic status confirming a social inequality in

  maternal smoking. Women at risk of smoking during pregnancy must be

  identified in early pregnancy or even before pregnancy and be offered

  interventions to help them quit smoking.'
