OP-003 Screen time among urban teenagers of different ages

Aim To determine the characteristics of using screens by adolescents of different genders and ages. Material and Method The data was obtained during the study 'Health Behavior of School-Age Children' 2022; 1,225 adolescents from secondary schools in Irkutsk were surveyed. The 'screen time' section of the questionnaires was taken for watching TV, using social networks and playing computer games. Children's gender, age and screen time were analyzed. Results 1211 questionnaires (614 boys) were selected. Teens were asked how many hours per day they spent 'on screens' for each activity. Children were divided into 4 groups: first included teenagers who do not use screen activities; second - less 2 hours; third - 2–5 hours; fourth - more 5 hours. The gender and age values of the groups were assessed for each type of activity separately.54% of teenagers play games less than two hours a day (40.5%) or not at all (13.6%). 52.1% of boys and 39.7% of girls play more than 2 hours. 57.3% of adolescents watch TV or videos on the Internet more than 2 hours, 30.7% watch more than 5 hours a day. Comparable for boys and girls of all age groups.53.3% of teenagers spend more than 2 hours a day on social networks. The majority of them in all age groups spent 2–5 hours. There are significantly more boys who do not use social networks at all compared to girls (21.7% vs 14.7%). Across girls' age groups, time spent on social media increased significantly with age: 61% of 13- and 15-year-old girls spent more than two hours on social media daily. Conclusions Adolescents increase screen time as they get older, which can become a risk factor for health and lead to chronic diseases in the future.
