Purpose

The aim of the study was to evaluate the physical activity level, nutritional behaviours, and body silhouette concern in 15–17-year-old boys and girls from Eastern European countries.

Methods

The research, carried out in 2015, involved 2145 secondary school adolescents, including 877 boys and 1268 girls (mean= 16.5, SD= 2.0). The results of the International Physical Activity Questionnaire (IPAQ) and Health Behaviours Questionnaire were analysed.

Results

The questionnaire results allowed to conclude that boys were definitely more active than girls. A significant relationship between physical activity and the number of meals was found. Another significant relationship was observed between higher physical activity in boys who wanted to gain weight and in girls who wanted to lose weight.

Conclusions

Both boys and girls have positive attitudes towards their health with regard to their level of physical activity, nutritional behaviours, and body silhouette concern. A significant relationship was found in the interrelationship among the features considered, with simultaneous gender differentiation.
