ABSTRACT

Physical activity during childhood and adolescence is associated with substantial health benefits and tracks into adulthood. Nevertheless, only 22.7% of German adolescents are sufficiently physically active. Thus, the promotion of an active lifestyle in youth is an essential issue of public health.This study will evaluate the implementation and efficacy of the "lauft." program to enhance physical activity in adolescence. "lauft." is a multicomponent school-based program developed on the basis of effective strategies for health interventions and behavioral change.Methods/design: The "lauft." physical activity program targets four different levels. (a) Each student receives a pedometer and documents his/her steps over 12 weeks using an interactive user account on the "lauft." homepage. (b) For classes there will be different competitions, with achieving the most steps in selected weeks, the highest increases of steps and developing the most inventive ideas to promote physical activity in school. Besides, the intervention includes four educational lessons. (c) The headmasters and teaching staff of the participating schools will get information material with suggestions and encouragement to enhance physical activity in school. Participating teachers will be invited to an introductory seminar. (d) Parents will be provided with informational material about the program and will be invited to a parent-teacher conference about the benefits of being physically active and how they can support their children in engaging in a physically active lifestyle.To evaluate the efficacy of the "lauft." physical activity program, a two-arm cluster randomized controlled trial will be conducted in three waves: (1) baseline assessment, January/February 2014, (2) post assessment, June/July 2014 and (3) 12-month follow-up assessment, June/July 2015. Data collection will include physical and medical testing, self-administered questionnaires, group discussions and document analyses.
"lauft." aims at fostering a physically active lifestyle in adolescence while a considerable decline of physical activity is present. Physical activity programs based in the school setting and following a multicomponent approach have been proven to be most successful. Furthermore, the use of pedometers is promising to enhance physical activity during the entire day and targets a wide range of adolescents regarding fitness and weight.Trial registration: Current Controlled Trials ISRCTN49482118.

    ABSTRACT: The study investigated the effects of sedentary behavior (SB) on mental well-being and examined differences between screen-based (sSB) and non-screen-based sedentary behaviors (nSB) separately by gender. In a total sample of 1296 students (609 girls) aged 12-17 (m = 13.7, SD = 0.67), SB, depressed affect, self-esteem, physical self-concept, general self-efficacy and physical activity were assessed through self-administered questionnaires. Among girls, lower scores in self-esteem, physical self-concept as well as general self-efficacy were associated with higher sSB but not nSB. Among boys higher levels of sSB related to higher self-esteem, nSB but not sSB predicted higher scores in depressed affect, and there was a u-shaped association between sSB and general self-efficacy. Results replicate the inverse association between SB and mental well-being, and suggest a distinction between nSB and sSB especially among girls. Additional studies will be necessary to replicate, and further examine mediating mechanisms. Copyright © 2015 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

    ABSTRACT: Objective: To evaluate the immediate effects of a school-based multi-component program to foster a physically active lifestyle in adolescence. Design/participants: In a cluster-randomized controlled trial with pre- and post-assessment in 2014, 29 schools with 1,162 8th grade students (48% girls) from Germany were included. Age ranged from 12 to 17 years (M=13.74; SD=0.67). Intervention: While the control group attended education as usual, students in the intervention group received pedometers and took part in a class competition over a time period of 12 weeks. Classes with the most steps and best creative ideas to promote physical activity in everyday life were awarded. Main outcome measures: Primary outcomes included out-of-school sports activities (h/week), moderate to vigorous physical activity (d/week with a minimum of 60 minutes), active commuting (min/day), doing chores (min/day), and sedentary behavior (h/day) assessed through self-administered questionnaires as well as cardiorespiratory fitness measured using the 20m shuttle-run test (completed laps). Results: Significant interaction terms between group and wave of assessment were found on out-of-school sports activities (b=-1.09 [-1.89; -0.29], p=0.008), moderate to vigorous physical activity (b=-0.29 [-0.47; -0.10], p=0.002), and active commuting (b=-20.41 [-32.32; -8.49], p=0.001): students in the intervention group showed a higher increase of physical activity levels than students in the control group. The intervention effect on cardiorespiratory fitness missed significance marginally (b=-1.52 [-3.14; 0.98], p=0.065), There was no effect on students' sedentary behavior (b=0.06 [-0.72; 0.84], p=0.881). Conclusions: An easy to administer school-based physical activity program (12 weeks) may enhance students' leisure-time physical activity. Trial registration number: ISRCTN49482118.
