Influence of smoking habits on mental status in Japanese women during the first trimester of pregnancy.

<bold>Purpose: </bold>We examined the relation between smoking habits and maternal mental status such as depression and anxiety during the first trimester of pregnancy.<bold>Material and Methods: </bold>Between July 2016 and June 2018, we examined the increased odds of depressive and anxiety symptoms in the women with smoking habits during prepregnancy with and without smoking cessation during the first trimester of pregnancy in comparison with those without smoking habits using self-administered questionnaires.<bold>Results: </bold>The rate of depressive and anxiety symptom in the women with smoking habits during prepregnancy (46.4 and 47.3%, respectively) was higher than those in the women without smoking habits during the first trimester of pregnancy irrespective of smoking cessation. The rate of depressive or anxiety symptom during the first trimester of pregnancy did not change significantly by smoking cessation in the women with smoking habits during prepregnancy (depressive symptom: 44.6 versus 53.7%, p = .13; anxiety symptom: 45.3 versus 55.2%, p = .17).<bold>Conclusions: </bold>Smoking habits during prepregnancy seemed to be associated with the increased perinatal mental disorders irrespective of smoking cessation.
