[The relationship between tobacco smoking and risk behaviour syndrome among 15-year-old adolescents in Poland and other European countries].

In most of studies on the multiple risk behaviour syndrome, tobacco smoking is consider as one of the main components. In this paper smoking was excluded from this syndrome. On the contrary, a set of behaviours that includes: alcohol abuse, cannabis use and aggressive behaviours (bullying, fighting) was described and its association with smoking related behaviours was evaluated. Data were collected from 15-year-old students (N = 50618) from 28 countries participating in Health Behaviour in School-aged Children (HBSC) survey in 2005/06. Representative samples of pupils completed a standardised questionnaire during school hours in each country. Risk Behaviour Syndrome (RBS) was measured on the scale ranged 0-12 points, categorized into 3 levels. We tried to answer the following questions: 1) is early tobacco onset related with the higher risk of being involved in multiple problem behaviours; 2) what is the prevalence of regular tobacco smoking among adolescents reporting multiple problem behaviours; 3) in what extent gender modifies above relationships; 4) are similar patterns observed in Poland and combined international sample. The results have shown, that in Poland 22.6% of boys and 5.0% of girls reported high level of RBS (6 points or more). The prevalence of every day smoking was equal to 14.9% and 10,1%, in boys and girls, respectively. This percentage increased to 38.8% and 61.0% in the group of boys and girls reporting high score on RBS scale. More boys than girls started to smoke at age 13 yrs or earlier (38.6% vs. 27.1%). Adolescents who begun smoking earlier, were more likely to be regular smokers at age 15, and more likely to report multiple risk behaviors. In all countries the influence of early tobacco onset on the RBS is more evident among girls.
