Despite the current level of medical technology, adverse pregnancy outcomes associated with preventable causes, such as maternal smoking and secondary exposure of the fetus to tobacco smoke through passive smoking, remain a serious public health problem. Purpose of the study: to substantiate ways to improve the prevention of tobacco and nicotine-containing product consumption in pregnant women. Materials and methods. We analyzed domestic and foreign studies on smoking during pregnancy conducted at the national, regional and global levels, time series of integral indicators of maternal and child health, approaches to predicting the degree of perinatal risk, as well as the age structure of women giving birth in the Russian Federation for 2010—2022 with the calculation of linear trend models. Results. In Russia, the proportion of pregnant women who smoked during pregnancy before delivery ranges from 15% to 23%. The share of traditional cigarettes accounts for 61.7% (95% CI: 52.2—70.5), smokeless products were used by 20.9% (95% CI: 14.1—29.7) and 17.4% were dual smokers (95% CI: 12.6—17.8). The majority (79.1%) of female smokers, whose average age was 29.5±5.2 years, are confident in the safety of smokeless products for the fetus and newborn. During 2010—2022, a trend of decreasing perinatal mortality and increasing maternal mortality was observed in the Russian Federation. The dynamics of the number of women giving birth in the age groups 15—24 and 25—34 were characterized by the same downward trend, but increased in the group of 35 years and older. Conclusion. Thus, timely detection and correction of tobacco and nicotine-containing product consumption by primary care health workers in women of childbearing age at the stages of pre-pregnancy preparation and pregnancy management, lactation and dynamic monitoring of the child can have enormous demographic and socio-economic significance.
