Summary
Aim. To assess the social and economic factors that influence tobacco smoking prior to pregnancy.
Material and methods. This research was conducted among mothers who gave birth to babies in the two least developed counties in Hungary (Borsod-Abaúj-Zemplén and Szabolcs-Szatmár-Bereg) in 2009. Data were obtained from medical records of obstetrical wards and structured interviews conducted by local maternity and child service. There were 7,877 women with complete data on smoking habits among 9,040 women in the study. This represents 9.4% of total live births in Hungary and 71.1% of all live births in the two counties.
Results. The overall prevalence of smoking prior to pregnancy was 46.0%. Smoking women were typically less than 18 years old, underweight, with the lowest levels of education, those living in non-contractual cohabitation, and those with unhealthy dietary habits (p<0.001), further living in deep poverty (p < 0.05).
Conclusions. While planning preventive actions to reduce female tobacco use in gestational age, the socioeconomic situation must be considered.
Introduction
While male tobacco smoking has levelled off in most of the developed countries, the frequency of smoking among women is on the rise. The European average is near 34%. Hungary is comparable to Greece, Portugal, Bosnia, Spain, and the United Kingdom. Only in Austria and Serbia is the frequency of smoking among women higher than in Hungary (1). Young girls start smoking very early and are often addicted smokers by the time they reach young adulthood. The prevalence of tobacco smoking among women aged 18-44 is 30.8% in Hungary (2). The level of education and the mother’s active employment influence smoking cessation (3). Tobacco use and exposure to secondhand smoking is extremely dangerous for the mother and the foetus. Smoking contributes to premature birth (< 37 weeks gestation), low birth weight (< 2500 grams) (4). In 2009 Hungary’s preterm births (PTB) and low birth weight (LBW) frequency (8.7% and 8.4%) was well-above the average of the European Union (EU), which was 6% (4, 5). In addition, 85% of the morbidity among newborn babies is due to PTB and/or LBW. The frequency of developmental disorders, stillbirth and other infant conditions (6), and the incidence of SIDS are growing (7).
In our study we aimed to identify socioeconomic factors that predicted smoking prior to pregnancy among mothers who gave birth to babies in the two least developed counties in Hungary (Borsod-Abaúj-Zemplén = BAZ, and Szabolcs-Szatmár-Bereg = Szabolcs) in 2009.
Material and methods
Our research was approved by the Ethical Committee of Semmelweis University. In the two countries mentioned above, mothers who gave birth to live babies between January 1, 2009 and December 31, 2009 were invited to participate in our research. The final sample was 9,040 mothers, which represents 71.1% of all mothers (N = 12,732) of live birth cases in these two counties. It means 9.4% of all live births (96,442) in Hungary during 2009. Mothers were informed about the aims of the research and the method we applied, and they provided formal consent to participate.
Data were obtained from medical records of obstetrical wards and through in-person interviews administered by the local maternity and child service.
Demographic, Social and Economic status: we measured the mothers’ age groups (years < 18, 18-34, 35-40, 41+), ethnicity (self-admitted as Roma or non-Roma), body mass index (BMI = kg/m2) converted to a categorical variable (underweight = <18.49, normal weight = 18.5-24.9, overweight = 25-29.9, obese = 30 or greater), level of education (less than 8 grades of primary school, completed 8 grades, secondary education, college and/or university), employment status (employed, unemployed, varia as students, disabled, on social benefit), marital status (married, non-contractual cohabitation, separated or divorced, single or widowed), number of children converted also to 3 categories (1-2, 3-6, 7-13), and dwelling circumstances (full, partial amenities and without basic amenities [running water, indoor plumbing, and heat]). Level of income/capita was determined by comparing the self-reported family income with data of the Central Statistical Office (CSO). Thus, the upper limit of deep poverty is reached if there are two children and two employed adults in the family and the income per capita is less than half of the average income per capita of the relevant year (8, 9). Poverty means 50-80%, at poverty level 80-120%, sufficient 120-170% and wealthy above 170% of this level.
Health Behaviours: dietary habits related to fresh fruits, vegetables, dairy and meat products in 4 categories of consumption were measured (at least once a day, every other day, once or twice a week, less than once a week). Coffee and alcohol (wine and beer) consumption were measured in 3 categories (coffee: at least every other day, 1-2 times a week and seldom or never, alcohol: at least once a week, less than per week, and never).
Descriptive statistics (means, standard deviations, 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 socioeconomic and health behavior status to smoking prior to pregnancy. Results are reported in odds ratios (ORs) and 95% confidence interval (CI). All data were analysed using SSPS (19.0) statistical program.
