Background: Health behaviours are consolidated and modified throughout human life; however, adolescence is a significant stage in the process of acquiring them.One of theidentifiers of the represented health behaviours is a proper level of body fat influenced by self- assessment of own image. Material/Methods: The authors considered relationships between the real image, health behaviours and self-assessment of own appearance; these were analysed using a sample of randomly selected 830 adolescents. The body composition analysis was conducted by means of bioelectrical impedance, assessment of self-image was done with Stunkard’s Figure Rating Scale, and assessment of health behaviours was done with Juczyński’s Health Behaviour Inventory. Results: The mediatory role of health behaviours between the actual body outline and the self-assessment of body image as well as the desired body was not observed; nonetheless, most of the respondents wanted a slimmer body. Conclusions: The observed difference between self-assessment of the real and the desired body and the related consequences for physical and psychological health encourage one to include promotion of a positive body image itself to stabilize high body self-esteem.
