Introduction Health risks associated with prenatal exposure to tobacco smoking are well- established. Maternal smoking influences not only the perinatal period of the neonate, but also it may have long-term consequences, such as behavioral disorders and pulmonary diseases in childhood. The aim of our research was to study tobacco use and its correlates (socio-economic background, demographic status and other lifestyle factors) among expectant mothers as well as birth outcomes. The results of our research will be applied to the training of health care personnel active in field prevention in the maternal and child health service in Hungary Objectives to assess relationships among socio-economic factors and preterm birth and/or /low birth weight to measure the frequency of expectant mothers’ smoking and identification of factors contributing to regular smoking to understand the impact of smoking on the infants’ biometric measures and adaptation. Methods Our research was conducted among mothers with live-born babies in two counties of Hungary. We reached 9,040 mothers, which represents 71% of the pregnant population and 9.4% of all live births in Hungary in Data were obtained from two sources: 1) Medical records of obstetrical wards and 2) In-person interviews Data were analyzed by SPSS ( ) statistical program Descriptive statistics (means, sd, ranges and frequencies) were used to describe the sample. Bivariate associations were calculated on all variables and their relationship to smoking status using the Pearson’s Chi-square test. Logistic regression analyses were computed to assess the relationship of socio-economic status to smoking versus non-smoking. Results are reported in odds ratios (ORs) at 95 % confidence interval (CI). Results The rate of smoking during pregnancy is very high in the two measured counties. Smoking is more frequent among mothers who live in poverty and deep poverty. Low level of education, unemployment, ethnicity, and family status influence significantly the frequency of smoking. Conclusions Smoking attitudes and health status depend on level of education, socio-economic position, and social relationships. There is a need for cooperation of health care, education and civil and governmental organizations in order to reduce tobacco use among expectant mothers. As there are equality problems while accessing health care services, setting up available facilities at primary and secondary level in rural and underdeveloped regions would also be necessary in providing the necessary cessation services for expectant mothers.
