To understand the evolution of health behaviours and planning efforts to change them, the system prospects of these behaviours determinants are needed. Complex theoretical models to explain taking and maintaining health behaviours are designed for it. The aim of the manuscript is to analyse theoretical models of health behaviours with regard to the possibility of using them to evaluate health behaviours. Summarizing the possibilities of applying theoretical models that explain taking and maintaining health behaviours, it can be confirmed that all models may be used to explain health behaviours. In practical actions the most convenient is to apply general rules of behaviour shaping and changing based on using all methods. However, no single theory or model explain and predict all possibilities of health behaviours and therefore, further research of this problem is essential. Models should be perceived as a description with a formalized structure helping understand factors that influence individual decisions and behaviours helpful in planning effective interventions of health promotion.

Key words: health behaviours, theoretical models.
