Multiple Health Risk Behaviour in Czech Adolescents: Family, School and Geographic Factors

The study examines the relationship of family, school and geographic factors in relation to the prevalence of different health risk behaviours among Czech adolescents (aged 15–16 years) based on cross-sectional study design. Risk behaviours such as cigarette smoking, alcohol drinking and marijuana use among adolescents have often been shown to co-occur with each other. Data from the European School Survey Project on Alcohol and Other Drugs 2007 were used. A total of 7616 students from the Czech Republic were analysed in the study. About two thirds of students (63.5%) did not engage in any type of considered health risk behaviour, 21.1% reported one risk, 10.8% two risks, and 4.6% three risks. Thus, in sum 15.4% of Czech, students were engaged in multiple risk behaviour forms. Separate multilevel logistic regression models were performed in order to explore the redistribution of factors on categories of multiple health risk behaviour.
