TY - JOUR A1 - Gmeiner, Michaela Silvia A1 - Warschburger, Petra T1 - Psychotherapie bei juveniler Adipositas BT - gerechtfertigt und sinnvoll? JF - Psychotherapeut N2 - Background Obesity is widespread in childhood and adolescence. Medical rehabilitation measures with a comprehensive range of treatment options represent an essential pillar of care. As obesity is associated with a wide range of psychosocial burdens, the question arises as to whether psychotherapeutic services should be given even greater consideration. Objective The main goal was to examine the rate of psychological problems among children and adolescents with obesity and their association with the weight loss course. Material and methods The sample consisted of 220 children and adolescents with obesity (8-16 years, M = 13.11 years, SD +/- 1.88 years; 54.5% female) who participated in an inpatient rehabilitation. Emotional and behavioral problems were assessed (strengths and difficulties questionnaire, SDQ via parental report) at the beginning of rehabilitation as well as 6 and 12 months after completion. Anthropometric data for determination of the weight status were collected by medical personnel of the clinics or in the follow-up by family doctors. Results Almost half of the children and adolescents (48.6%) showed abnormal values and girls in particular were affected significantly more often. The descriptive inspection after rehabilitation revealed a similarly high proportion. The presence of psychological problems had a significant negative effect on the weight course. Conclusion Psychological problems should be given greater consideration in the context of obesity therapy. On the one hand potentially burdened children should be identified by screening, on the other hand psychotherapy to reduce psychosocial strain should be an integral part of the treatment concept. N2 - Hintergrund Adipositas ist im Kindes- und Jugendalter stark verbreitet. Medizinische Rehabilitationsmaßnahmen mit ihrem umfassenden Behandlungsangebot stellen eine wesentliche Säule der Versorgung dar. Da Adipositas mit vielfältigen psychosozialen Belastungen verbunden ist, stellt sich die Frage, ob psychotherapeutische Angebote noch stärker berücksichtigt werden sollten. Fragestellung Untersucht wurde, wie verbreitet psychische Auffälligkeiten bei Kindern und Jugendlichen mit Adipositas sind und in welchem Zusammenhang sie zum Gewichtsverlauf stehen. Material und Methoden Die Stichprobe bestand aus 220 Kindern und Jugendlichen mit Adipositas (8 bis 16 Jahre, M = 13,11 Jahre; SD ± 1,88 Jahre; 54,5 % weiblich), die an einer stationären Rehabilitationsmaßnahme teilnahmen. Emotionale- und Verhaltensauffälligkeiten (Strengths and Difficulties Questionnaire, SDQ) wurden zu Rehabilitationsbeginn sowie 6 und 12 Monate nach Rehabilitationsende im Elternbericht erfasst. Zudem wurden Daten zur Bestimmung des Gewichtstatus durch das medizinische Personal der Kliniken bzw. in der Katamnese von Hausärzten erhoben. Ergebnisse Fast die Hälfte der Kinder und Jugendlichen (48,6 %) wies auffällige Werte auf; v. a. Mädchen waren signifikant häufiger betroffen. Die deskriptive Betrachtung nach Rehabilitationsende zeigte einen vergleichbar hohen Anteil. Zudem wirkte sich das Vorliegen psychosozialer Auffälligkeiten signifikant negativ auf den Gewichtsverlauf aus. Schlussfolgerung Psychische Probleme sollten im Rahmen der Adipositastherapie stärker berücksichtigt werden. Zum einen sollten evtl. belastete Kinder durch Screenings identifiziert werden, zum anderen psychotherapeutische Maßnahmen zur Reduktion psychosozialer Belastungen integraler Bestandteil der Behandlung sein.

T1 - Using AI for mental health analysis and prediction in school surveys JF - European journal of public health N2 - Background: Childhood and adolescence are critical stages of life for mental health and well-being. Schools are a key setting for mental health promotion and illness prevention. One in five children and adolescents have a mental disorder, about half of mental disorders beginning before the age of 14. Beneficial and explainable artificial intelligence can replace current paper- based and online approaches to school mental health surveys. This can enhance data acquisition, interoperability, data driven analysis, trust and compliance. This paper presents a model for using chatbots for non-obtrusive data collection and supervised machine learning models for data analysis; and discusses ethical considerations pertaining to the use of these models. Methods: For data acquisition, the proposed model uses chatbots which interact with students. The conversation log acts as the source of raw data for the machine learning. Pre-processing of the data is automated by filtering for keywords and phrases. Existing survey results, obtained through current paper-based data collection methods, are evaluated by domain experts (health professionals). These can be used to create a test dataset to validate the machine learning models. Supervised learning can then be deployed to classify specific behaviour and mental health patterns. Results: We present a model that can be used to improve upon current paper-based data collection and manual data analysis methods. An open-source GitHub repository contains necessary tools and components of this model. Privacy is respected through rigorous observance of confidentiality and data protection requirements. Critical reflection on these ethics and law aspects is included in the project. Conclusions: This model strengthens mental health surveillance in schools. The same tools and components could be applied to other public health data. Future extensions of this model could also incorporate unsupervised learning to find clusters and patterns of unknown effects.

However, the physiological effects produced by each training modality could also interfere with each other, improving athletic performance less than single-mode training. Because anthropometric, physiological, and biomechanical differences between young and adult athletes can affect the responses to exercise training, young athletes might respond differently to concurrent training (CT) compared with adults. Thus, the aim of the present systematic review with meta-analysis was to determine the effects of concurrent strength and endurance training on selected physical fitness components and athletic performance in youth. A systematic literature search of PubMed and Web of Science identified 886 records. The studies included in the analyses examined children (girls age 6-11 years, boys age 6-13 years) or adolescents (girls age 12-18 years, boys age 14-18 years), compared CT with single-mode endurance (ET) or strength training (ST), and reported at least one strength/power-(e.g., jump height), endurance-(e.g., peak. VO2, exercise economy), or performance-related (e.g., time trial) outcome. We calculated weighted standardized mean differences (SMDs). CT compared to ET produced small effects in favor of CT on athletic performance (n = 11 studies, SMD = 0.41, p = 0.04) and trivial effects on cardiorespiratory endurance (n = 4 studies, SMD = 0.04, p = 0.86) and exercise economy (n = 5 studies, SMD = 0.16, p = 0.49) in young athletes. A sub-analysis of chronological age revealed a trend toward larger effects of CT vs. ET on athletic performance in adolescents (SMD = 0.52) compared with children (SMD = 0.17). CT compared with ST had small effects in favor of CT on muscle power (n = 4 studies, SMD = 0.23, p = 0.04). In conclusion, CT is more effective than single-mode ET or ST in improving selected measures of physical fitness and athletic performance in youth. Specifically, CT compared with ET improved athletic performance in children and particularly adolescents. Finally, CT was more effective than ST in improving muscle power in youth.

But even though some studies on risk factors for disordered eating in sports exist, most research on this topic is based on cross-sectional data with limitations on causal inferences. We examined sports-related risk factors for disordered eating in a 1-year longitudinal study with two assessment points. The participants were 65 adolescent athletes from aesthetic sports (mean age 14.0 +/- 2.2years) who completed measures of disordered eating, social pressure from the sports environment, sports-related body dissatisfaction, desire to be leaner to improve sports performance, and emotional distress resulting from missed exercise sessions. All variables were relatively stable in the mean. Individual changes in the desire to be leaner to improve sports performance were associated with individual changes in disordered eating. Furthermore, a cross-lagged partial correlation analysis showed that the desire to be leaner to improve sports performance was predictive of disordered eating and not vice versa. The results of our study indicate that athletes are more at risk for disordered eating if they believe it is possible to enhance their sports performance through weight regulation.

Bei Athleten mit einer Essstörung kann es darüber hinaus zu Einbußen in der Sportleistung kommen. Gerade für den Hochleistungssport ist es daher wichtig zu wissen, welches Risiko für Essstörungen besteht und wodurch das Risiko bedingt wird. Bisherige Studien zeigen deutliche Unterschiede zwischen den Sportarten. Eliteathleten aus ästhetischen Sportarten, wie rhythmische Sportgymnastik oder Eiskunstlauf, scheinen ein besonders hohes Essstörungsrisiko aufzuweisen. Deutlich geringere Prävalenzraten finden sich in Ballsportarten, wie Handball oder Basketball. Um zu verstehen, welche Aspekte der Sportart das Essstörungsrisiko beeinflussen, beschäftigt sich die vorliegende Arbeit mit der Rolle sportbezogener Variablen. In die Studien einbezogen wurden insgesamt 171 Athleten zwischen 11 und 18 Jahren (im Mittel 14.1 ± 1.8 Jahre) aus ästhetischen Sportarten und Ballsportarten, die einen Fragebogenpaket mit Instrumenten zu gestörtem Essverhalten, allgemeiner Körperunzufriedenheit, sozialem Druck im Sport, sportbezogener Körperunzufriedenheit, Schlankheitsstreben zur Leistungssteigerung und negativen Gefühle bei Trainingsausfall ausfüllten. Nach einem Jahr wieder befragt wurden 65 Athleten aus ästhetischen Sportarten. Nach Kontrolle von Alter, Geschlecht, BMI und allgemeiner Körperunzufriedenheit trugen sportbezogene Variablen signifikant zur weiteren Varianzaufklärung gestörten Essverhaltens bei. Die Längsschnittanalysen bestätigten einen Risikofaktorstatus für Schlankheitsstreben zur Leistungssteigerung. Zusammenhänge zwischen sportbezogenen Aspekten und gestörtem Essverhalten zeigten sich sowohl in Hochrisikosportarten für gestörtes Essverhalten (ästhetischen Sportarten), als auch in Niedrigrisikosportarten für gestörtes Essverhalten (Ballsportarten). Mit Ausnahme von negativen Gefühlen nach Trainingsausfall traten die sportbezogenen Variabeln häufiger in den ästhetischen Sportarten auf als in den Ballsportarten. Die eigenen Befunde verdeutlichen somit, dass der Einbezug potentieller sportbezogener Risikofaktoren − zusätzlich zu den allgemeinen Risikofaktoren − zum besseren Verständnis der Essstörungssymptomatik von Athleten beiträgt. Vor allem die Bedeutung von Gewicht für die Leistung beeinflusst das Essstörungsrisiko bei Athleten und ist stärker ausgeprägt in Hochrisikosportarten für Essstörungssymptomatik. N2 - Eating disorders such as Anorexia Nervosa and Bulimia Nervosa are serious, difficult-to-treat psychiatric disorders. For elite athletes, in addition to impairment in health and everyday life, an eating disorder can lead to a decline in sports performance. Knowledge of the risk for eating disorders in sports is therefore important. Prevalence rates for disordered eating vary depending on the type of sport. A particularly high risk was found in elite athletes from aesthetic sports such as figure skating or dance. Prevalence rates are lower in ballgame sports, such as handball or basketball. The purpose of this study was to focus on sport-specific variables in different sport types and to examine their relation to disordered eating. One hundred and seventy-one aesthetic and ballgame sports athletes participated in this study (mean age 14.1 ± 1.8 years). At a follow-up survey one year later, 65 athletes from aesthetic sports participated again. The questionnaire package included disordered eating, general body dissatisfaction, social pressure to be lean from sports environment, sports-related body dissatisfaction, desire to be leaner to improve sports performance and emotional distress resulting from missed exercise sessions. In predicting eating disorder symptoms in athletes from aesthetic sports, we observed that after controlling for sex, age, BMI, and body dissatisfaction, sports-related variables were able to account for an additional variance in disordered eating. The longitudinal analyses indicated that a desire to be leaner to improve sports performance is predictive of disordered eating in aesthetic sports. Sports-related variables were associated with disordered eating also in ballgame sports, but some risk factors, such as the desire to be leaner to improve sports performance, were less prevalent. In conclusion of these results, sports-related parameters are relevant for understanding eating disorder symptomatology in sports. Athletes seem to be more at risk if they perceive the possibility to enhance sports performance through weight-regulation, which is more prevalent in aesthetic sports.
