Introduction: There are concerns that tobacco control policies may be less effective in reducing smoking among disadvantaged socioeconomic groups and thus may contribute to inequalities in adolescent smoking. This study examines how the association between tobacco control policies and smoking of 15-year-old boys and girls among 29 European countries varies according to socioeconomic group.
Methods: Data were used from the Health Behaviour in School-aged Children (HBSC) study conducted in 2005/2006 comprising 50,338 adolescents aged 15 years from 29 European countries. Multilevel logistic regression analyses were conducted to assess the association of weekly smoking with components of the Tobacco Control Scale (TCS), and to assess whether this association varied according to family affluence (FAS). Analyses were carried out per gender and adjusted for national wealth and general smoking rate.
Results: For boys, tobacco price was negatively associated with weekly smoking rates. This association did not significantly differ between low and high FAS. Levels of tobacco-dependence treatment were significantly associated with weekly smoking. This association varied between low and high FAS, with higher treatment levels associated with higher probability of smoking only for low FAS boys. For girls, no tobacco policy was significantly associated with weekly smoking, irrespective of the FAS.
Conclusions: Results indicated that most tobacco control policies are not clearly related to adolescent weekly smoking across European countries. Only tobacco price seemed to be adequate decreasing smoking prevalence among boys, irrespective of their socioeconomic status.

Highlights:
We examine social inequalities in associations of tobacco control with youth smoking.
Multilevel analyses were applied separately for boys and girls.
Tobacco price was associated with lower male smoking, independent of family affluence.
Female smoking was not associated with tobacco control policies.
