In order to characterize motor activity of Belarusian adolescents considering duration of individual components of the daily regime, to reveal nature of influence of social economic characteristics of families in which adolescents are brought up on parameters of their physical activity, material was analyzed taken from original database compiled on the basis of survey of 1254 adolescents aged 15–18 years (the sampling quoting Republican). It is established that motor activity of Belarusian adolescents has no gender differences and no differences conditioned by place of residence and is characterized as insufficient one. The every tenth teenager is outdoors for less than one hour per day, and 56.05% of girls and 50.31% of boys (p=0.042) are outdoors for less than two hours per day. Almost 2/3 of respondents spend three or more hours daily at the computer, telephone, regardless of gender and place of residence. The level of physical activity of adolescents is associated with duration of their interaction with gadgets. The higher risk of insufficient motor activity in combination with prolonged use of digital devices, regardless of gender and place of residence, is demonstrated by adolescents who spend less time for homework preparation. The relationship between adolescent lifestyle and family characteristics is confirmed. The risk related to avoiding health-preserving modes of spending free time is higher in case of lower self-assessment of financial situation of their family, and by some components in adolescents from incomplete families. The education of parents is significant factor. For commitment to healthy motor activity of modern Belarusian teenager it is necessary to form self-organization skills, and motivation against the background of positive emotional psychological reinforcement from the family.
