TY - JOUR A1 - Pawellek, Sabine A1 - Ziegeldorf, Alexandra A1 - Wulff, Hagen T1 - Strategien und Effekte digitaler Interventionen bei der Übergewichts- und Adipositastherapie von Kindern und Jugendlichen BT - ein systematischer Review BT - a systematic review JF - Bundesgesundheitsblatt, Gesundheitsforschung, Gesundheitsschutz N2 - Background Rising obesity prevalence in childhood and adolescence are characterized by unhealthy lifestyles such as low physical activity due to high media use. Recent studies use the accessibility of this target group through digital media, whereby technologies represent new approaches in the intervention design of weight reduction. However, the question arises as to which digital combinations and methodological program concepts condition effective body mass index (BMI) changes. Aim To gain insights into effective program design and media use; digital intervention strategies for BMI reduction in overweight and obese children and adolescents will be analyzed and evaluated. Methods A systematic review was conducted in the databases MEDLINE via PubMed, Science Direct, and Web of Science to analyze studies from 2016 to 2021 on changes in BMI and BMI z-score of overweight and obese 6- to 18-year-olds. Methodological study quality was assessed according to the Cochrane Risk of Bias guidelines. Results From 3974 studies, seven articles describing the use of fitness wristbands, smartphones, and computer-based programs were identified. All media achieved BMI reductions, with smartphone interventions via calls and messages causing the most significant changes. Discussion Smartphones as providers of digital programs (e.g., apps) offer effective approaches to obesity reduction. Based on the data, the selection and combination of several media as well as the relevance of family involvement and the methodological foundation of the measures are confirmed. Due to the young age of the participants, media interventions must be made accessible to the target group. N2 - Hintergrund Steigende Adipositasprävalenzen im Kindes- und Jugendalter sind geprägt von ungesunden Lebensweisen wie geringer Bewegung durch hohen Medienkonsum. Neueste Studien nutzen die Erreichbarkeit dieser Zielgruppe durch digitale Medien, womit Technologien neue Ansätze in der Interventionsgestaltung der Gewichtsreduktion darstellen. Allerdings stellt sich die Frage, welche digitalen Kombinationen und methodischen Programmkonzepte effektive Body-Mass-Index(BMI)-Veränderungen bedingen. Ziel Um Erkenntnisse über effektive Maßnahmengestaltung und Medieneinsatz zu gewinnen, sollen digitale Interventionsstrategien zur BMI-Reduktion übergewichtiger Kinder und Jugendlicher analysiert und bewertet werden. Methoden Ein systematischer Review wurde in den Datenbanken Medline via PubMed, Science Direct und Web of Science zur Analyse von Studien aus den Jahren 2016 bis 2021 über Veränderungen im BMI und BMI-Z-Score von übergewichtigen und adipösen 6‑ bis 18-Jährigen durchgeführt. Die methodische Studienqualität wurde nach den Richtlinien des Cochrane Risk of Bias bewertet. Ergebnisse Aus 3974 Studien wurden 7 Artikel identifiziert, die den Einsatz von Fitnessarmbändern, Smartphones und computerbasierten Programmen beschreiben. Alle Medien erzielten BMI-Reduktionen, wobei Smartphoneinterventionen via Anrufe und Nachrichten die signifikantesten Veränderungen bewirkten. Diskussion Smartphones bieten als Anbieter digitaler Programme (z. B. Apps) effektive Ansatzpunkte zur Adipositasreduktion. Auf Basis der Datenlage bestätigt sich neben der Auswahl und der Kombination mehrerer Medien die Relevanz des Familieneinbezugs und die methodische Fundierung der Maßnahmen. Aufgrund des jungen Alters der Teilnehmenden müssen mediale Interventionen zielgruppengerecht zugänglich gemacht werden.

Therefore, we studied the prevalence of sarcopenia and its association with cardiometabolic risk factors as well as muscular and cardiorespiratory fitness using data from the German Children's Health InterventionaL Trial (CHILT III) programme. In addition to anthropometric data and blood pressure, muscle and fat mass were determined with bioelectrical impedance analysis. Sarcopenia was classified via muscle-to-fat ratio. A fasting blood sample was taken, muscular fitness was determined using the standing long jump, and cardiorespiratory fitness was determined using bicycle ergometry. Of the 119 obese participants included in the analysis (47.1% female, mean age 12.2 years), 83 (69.7%) had sarcopenia. Affected individuals had higher gamma-glutamyl transferase, higher glutamate pyruvate transaminase, higher high-sensitivity C-reactive protein, higher diastolic blood pressure, and lower muscular and cardiorespiratory fitness (each p < 0.05) compared to participants who were 'only' obese. No differences were found in other parameters. In our study, sarcopenic obesity was associated with various disorders in children and adolescents. However, the clinical value must be tested with larger samples and reference populations to develop a unique definition and appropriate methods in terms of identification but also related preventive or therapeutic approaches.
