title: [Media use and physical activity patterns of adolescent participants in obesity therapy: Analysis of the impact of selected sociodemographic factors].
abstract: To meet the challenge of obesity, effective therapeutic concepts for adolescents focusing on lifestyle changes are necessary. Particularly relevant are nutrition and physical activity patterns associated with media use, which can be influenced by sociodemographic factors. For the optimization of obesity therapy approaches, it is essential to analyze these sociodemographic factors to adjust the aims, content, and methods of interventions, and to use the potential of media in treatment concepts. Thus, the research question is: what are the media and physical activity patterns of 11- to 17-year-old participants in obesity therapy, depending on sociodemographic factors? The national multicenter study was conducted from 2012 to 2013. A questionnaire was administered to 564 participants aged 13.4 ± 1.6 (mean ± standard deviation) years. Standardized instruments were used to assess the variables physical activity, media use, and sociodemographic factors. Participants were physically active for 1 h on 3.3 ± 1.8 days per week, 8.5 % daily. Televisions, mobile phones, and computers were available in all sociodemographic groups and were used for 2 h per day. Sociodemographic differences can be seen in the extent of media usage (h/day). These differences can be found between girls and boys concerning their usage of mobile phones (2.49 vs. 1.90; p  < 0.001), between 11- to 13- and 14- to 17-year-old children concerning their usage of game consoles (0.55 vs. 1.65; p  = 0.007), and in the correlation analysis of media usage and physical activity. Compared with existing literature, the survey results reveal reduced activity and increased media use, which vary among the groups. Thus, differentiated therapy approaches appear to be reasonable. Future research needs to evaluate to what extent media, despite the risks, can contribute to the methodological support of therapy, training, and aftercare concepts.
