(DGSP) und Weiterbildungsorgan der Österreichischen Gesellschaft für Sportmedizin und Prävention N2 - According to the results of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) published in 2009, only 5% to 8% of the 15-17-year-old adolescents reach the current recommendations on health-enhancing physical activity This result (besides others in the survey) rests on data measured with the 25-item physical activity questionnaire for children and adolescents (MoMo-AFB). The present study compares two different methods of assessing physical activity with the purpose of testing the validity of the MoMo-AFB self-report. First, we measured the physical activity status of 73 15 to 18-year-old pupils (32 boys and 41 girls) over seven days via objective accelerometry (ActiGraph GT1M), then the pupils completed the MoMo-AFB for the same (previous) period. Results show that using the MoMo-AFB leads to higher levels of self-reported physical activity than measuring it with accelerometers. Furthermore, only the MoMo-AFB subscale MVPA (moderate-to-vigorous physical activity), that uses two single items to decide whether the health-enhancing physical activity recommendation is reached or failed, corresponds statistically significantly with the accelerometry data. For all other subscales (e.g. school- or leisure time activity), we found no agreement. Further research, first of all on the measurement quality of the MoMo-AFB but also on the physical (in)activity status of children and adolescents, is needed.

More than half of the girls and a third of the boys are dissatisfied with their weight. Nearly 70% of the male participants were unhappy with their muscles. Both forms of body dissatisfaction are influenced by similar sociocultural and psychological factors. While weight dissatisfaction leads to weight reduction strategies and disturbed eating, muscle dissatisfaction results in muscle enhancement methods. Potential harmful consequences of excessive muscle building techniques are discussed. The data emphasize the need for a sex-specific investigation of body dissatisfaction and its consequences. Body image aspects relevant to boys should be added to intervention and prevention approaches.

The MoMo-AFB consists of 28 items, covering the fields of everyday physical activity, sports within and outside of organised clubs, physical education as well as compliance with physical activity guidelines. A study was conducted with 109 boys and 87 girls aged between 9 and 17 years. The MoMo-AFB was given on two separate occasions to evaluate reliability and was compared with accelerometry data of ActiGraph GT1X to evaluate validity. The overall kappa/weighted kappa coefficient for the one-week testretest reliability was .66 (SD = .19) and the overall intraclass correlation (ICC) .68. Self-reported and accelerometer-measured average weekly time spent performing moderate to vigorous physical activity were significantly correlated (Spearman r = .29). Regarding reliability and validity, the MoMo-AFB is comparable with other international published physical activity questionnaires for adolescents.

T1 - Cognitive flexibility in adolescent patients with unipolar affective disorders - gender differences JF - Zeitschrift für Kinder- und Jugendpsychiatrie und Psychotherapie N2 - Objective: Several studies have revealed impairments in cognitive functions among patients with affective disorders (AD). However, to date there are few neuropsychological studies on cognitive flexibility among adolescent patients with AD, especially on gender differences in AD. Here, we investigate cognitive functions, especially cognitive flexibility, in adolescent patients with unipolar AD (UAD) compared to a healthy control group (CG). Method: The study population consists of 17 male patients (M-age = 15.4 +/- 1.3) and 22 female patients with UAD (M-age = 15.6 +/- 1.4) as well as 20 male (M-age = 16.0 +/- 1.0) and 30 female (M-age = 15.7 +/- 0.9) healthy adolescents. A neuropsychological test battery was conducted, and depressive symptoms, psychological stress, and intelligence were also assessed. Results: The analyses revealed no significant group differences regarding cognitive flexibility or visual processing speed, albeit slight better performance in motor processing speed for the CG. Furthermore, no gender differences were observed regarding cognitive flexibility, though female subjects general displayed better performance in processing speed. Conclusions: Overall, there are no indications for serious deficits and specific gender differences in cognitive flexibility or processing speed in adolescent patients with UAD. Independent of psychological distress, female subjects seem to have some advantages in processing speed.

BT - What Would a "Perfect Therapy" Look Like? JF - Die Rehabilitation : Zeitschrift für Praxis und Forschung in der Rehabilitation N2 - Hauptziel Adipositas ist eine der Hauptindikationen in der Kinder- und Jugend-Rehabilitation. Für ältere Jugendliche und junge Erwachsene fehlen altersspezifische Therapieangebote fast vollständig. Ziel war es die Wünsche bezüglich der Inhalte und Methoden einer „perfekten Therapie“ im Rahmen eines Rehabilitationsaufenthalts zu untersuchen. Methode Im Rahmen der YOUTH-Studie wurden 147 adipöse Jugendliche und junge Erwachsene beiderlei Geschlechts (zwischen 15 und 21 Jahren) mithilfe eines standardisierten Fragebogens befragt. Ergebnis Insgesamt zeigten sich relativ wenige alters- und geschlechtsspezifische Unterschiede. Interdisziplinär geleitete, koedukative Gruppen mit Elterneinbindung wurden gewünscht. Wichtige Themen waren gesunde Ernährung sowie psychosoziale Aspekte. Auch der Prävention von Rückfällen wurde eine hohe Relevanz zugeschrieben. Schlussfolgerung Psychosoziale Aspekte und die Vorbereitung auf mögliche Rückfallsituationen sollten integraler Bestandteil der Therapie sein. N2 - Principal objective Obesity is a major indication for pediatric and adolescent-rehabilitation. Age-specific therapies for „emerging adults“ are lacking. The aim was to examine the patients’ preferences with respect to the contents and methods of the „perfect therapy“ within an inpatient setting. Method In the context of the YOUTH study 147 obese male and female adolescents (aged 15–21 years) filled in standardized questionnaires. Results Overall little age- and gender-specific differences were observed. The participants expressed a preference for interdisciplinary coordinated and coeducational group approaches with involvement of the parents. Major topics were healthy nutrition and psychosocial aspects. Prevention of relapses is considered as important as well. Conclusion Psychosocial aspects and preparing coping with risk situations should be an integral part of treatment programs.
