Risk Behaviour of Adolescents Aged 10–15 in Slovakia. Relation to Sex, Age, and Body Mass Index

As a theoretical base we used Jessor’s concept of the Syndrome of Risk Behaviour in Adolescence, the self-concept, and the concept of
body image. AIM: The main aim of the contribution was research on the relations between the self-schema, specifically the physical proportions represented by BMI, and risk behaviour. The secondary aims were research on the relations between the self-schema, specifically the physical proportions represented by BMI, and sex and age. METHOD: In the research we used the 46-item modified version of the Risk BehaviourQuestionnaire (Čerešník, 2016). SAMPLE:We acquired data from almost 900 adolescents from all regions of Slovakia. They were aged from 10 to 15 (M = 12.69; SD = 1.48). They were attending the lower system of secondary schools. RESULTS: We found that there are significant sex and age differences in some manifestations of risk behaviour. We also found that adolescents with a higher BMI (above the 85th percentile) behave in a more risky manner.
