Results: According to the results of the study, numerous health problems associated with an unhealthy lifestyle are observed in Ukraine: physical inactivity, bad habits (use of alcoholic beverages and psychoactive substances, smoking), excessive communication on social networks, lack of safe sexual behavior skills. To increase the level of awareness of young people about a healthy lifestyle, we modeled the administration of services for the formation of a healthy lifestyle in the field of primary health care by a family doctor. Conclusions: One of the main links in the formation of a healthy lifestyle is the professional approach of this family doctor in the framework of performing his direct functions of eliminating habits and behavior that pose a risk to health and forming healthy lifestyle skills. Public administration should ensure the effectiveness of the family doctor in providing services for the formation of a healthy lifestyle through the process of collective adoption and implementation of strategic decisions.
