The aim of this work is an evaluation of the relation between risk behaviour of adolescents (bad eating habits, sedentary behaviour and abuse of psychoactive substances and stimulants) and fulfilling pro-health recommendations related with physical activity. The survey study was conducted in 2016 in Warsaw middle and high schools among 609 students using standardised international tools. World Health Organisation recommendations concerning pro-health physical activity level are met only by 24.2% of surveyed teenagers. Physical activity is a factor protecting teenagers from sitting for over 2 hours a day and bad eating habits. Prophylactic programs should consider promotion of physical activity.
