INTRODUCTION Concurrent use of tobacco products is associated with an increased risk of nicotine dependence and smoking-related health complications. Growing popularity of concurrent use of cigarettes and electronic cigarettes and/or waterpipe tobacco is of concern, especially due to the adolescents' exposure to nicotine and call for the better understanding of patterns and predictors of multiple product use. METHODS This is a secondary analysis of cross-sectional data obtained through the 2017 Global Youth Tobacco Survey conducted in Serbia on a nationally representative sample of 3362 students aged 13-15 years. Students were categorized into eight groups based on their experience with cigarette, e-cigarette and waterpipe use. To explore differences in sociodemographic and psychosocial characteristics, students were further placed in four groups: non-users; exclusive cigarette users; users of e-cigarette and/or waterpipe who do not smoke cigarettes; cigarette and other product users. RESULTS We show that among the 13-15 years old students, the most common pattern of tobacco/nicotine use is waterpipe and/or e-cigarette use with no cigarette smoking (7.5%, 95% CI: 6.6-8.4) followed by exclusive cigarette use (5.8 %, 95% CI: 5.0-6.6). Among cigarette smokers, 52.8% were exclusive cigarette smokers. Having the majority of their friends smoking is a mutual predictor for exclusive cigarette (AOR=33.2, 95% CI: 14.52-75.90) waterpipe and/or e-cigarette (AOR=2.57, 95% CI: 1.56-4.25) and cigarette and other products use (AOR=52.3, 95% CI:12.28-223.22) compared to no use of any product, and the same in the case of exposure at the point-of-sale marketing: exclusive cigarette vs not any product users (AOR=1.82, 95% CI: 1.22-2.73); waterpipe and or/ecigarette vs not any product users (AOR=1.64, 95% CI:1.18-2.28); and cigarette and other products vs not any product users (AOR=3.40, 95% CI: 1.99-5.80). CONCLUSIONS Tobacco control interventions should address dual- and poly-tobacco use with special focus on inter-personal factors and protection from exposure to advertising of e-cigarettes and waterpipes. © 2019 Kilibarda B.

Objectives Middle-and low-income countries rarely have national surveillance data on smoking in pregnancy. This nationwide population- representative survey investigated pre-and post-partum smoking and their predictors in Serbia. Methods Using stratified two-stage random cluster sampling, 2,721 women in 66 health care centres were interviewed at 3 and 6 months post-partum. Results 37.2% of women smoked at some point in pregnancy (average 8.8 cigarettes/per day). Smoking at pregnancy onset and during pregnancy was associated with smoking by others in the home and lower education and family socio-economic status. Almost a quarter of women (23.2%) who quit smoking during pregnancy did not relapse 6 months post-partum. Older women, primiparae, university students and white-collar workers were more likely to successfully quit smoking. More than a half of women were exposed to SHS in their homes (57.6%) and 84.6% allowed smoking in their homes. Conclusion Smoking during pregnancy in Serbia was two-to threefold higher than in the most affluent western countries. Target groups for action are women with lower education and socio-economic status, as well as health professionals and family members who smoke. © 2012 Swiss School of Public Health.

In a nationwide study of Serbian births, in 2008, we estimated the influence of maternal prenatal smoking and environmental tobacco smoke (ETS) exposure on birth outcomes. Using stratified two-stage random cluster sampling, 2,721 women were interviewed in-person (response rates 98.1 %), and 2,613 singleton live births were included. Date of birth, gender, birthweight, birth height and head circumference were copied from the official hospital Birth Certificate. Six exposure categories were defined according to mother's smoking history and exposure to ETS. We calculated adjusted mean values and group differences by analysis of covariance, and adjusted odds ratios for the low birthweight (LBW < 2,500 g). Compared to the reference category (non-smoking, non-exposed to ETS) we observed birthweight reductions in infants whose mothers smoked continuously during the pregnancy and were exposed to ETS (-162.6 g) and whose mothers were not exposed to ETS (-173 g) (p = 0.000, and p = 0.003, respectively), as well as reduction in birth length (-1.01 and -1.06 cm; p = 0.003 and p = 0.000, respectively). Reduction in birthweight and birth length related to exposure categories was not linear. Adjusted OR for LBW was almost tripled for mothers who smoked over the entire pregnancy and were non-exposed to ETS (aOR 2.85; 95 % CI 1.46-5.08), and who were exposed to ETS (aOR 2.68; 95 % CI 1.15-6.25). Our results showed strong effects of smoking throughout the pregnancy on reduced birthweight, birth length and head circumference, and increased risk for LBW. We were not able to detect an effect for ETS exposure alone. © 2012 Springer Science+Business Media New York.
