BACKGROUND: Disordered eating (DE) behaviors are relatively common among high-level dancers, especially in classical ballet. At the same time, interventions aimed at reducing DE behaviors in this population are scarce. METHODS: An 8-week exploratory preventive intervention for DE behaviors was carried out in a high-level ballet school for 40 teenagers aged 12-15 years (77.5% female). Both risk factors (perfectionism) and potentially protective factors (self-esteem, self-compassion) for the development of DE behaviors were considered. The intervention was created specifically for this study and consisted of five cognitive behavior therapy (CBT) workshops and four nutrition workshops. Additional components included newsletters for pupils and educational sessions and social media interactions with staff and parents. The intervention comprised two phases (control and intervention periods), with students acting as their own controls. Standardized questionnaires were completed before and after both phases. RESULTS: Questionnaire results did not indicate any changes in reported perfectionism, self-esteem, or self-compassion, nor were symptoms of DE affected during either the control or intervention periods. CONCLUSIONS: The intervention did not yield any discernible impact. However, it was affected by the onset of the COVID-19 pandemic, which limits our ability to draw conclusions about intervention effectiveness. Evaluations with pupils offer several considerations for future improvements.

Talent-school settings may generate stress via demanding expectations. To investigate students representing Norway's growing phenomenon of early adolescent talent schools, we interviewed twenty-seven 14-to15-year-old boys and girls about their experiences with self-and socially imposed expectations. Students were recruited from two sports schools (n = 14) and one school each with talent classes for ballet (n = 7) and music (n = 6). Using reflexive thematic analysis, we found four main themes representing the performers' accounts of (a) self-oriented expectations of persistent hard work, evoking self-doubts, and never-give-up attitudes; (b) coaches'/teachers' socially prescribed expectations, stimulating hard work, and pursuit of approval and opportunities; (c) parental expectations, reflected as helpful support, concerns of letting parents down, and negotiating independence; and (d) struggles with balancing expectations, reflected by demanding workloads, difficulties with prioritizing recovery, and ill-being. Early interventions targeting unhealthy self-and socially imposed expectations in high-expectation settings may be required to safeguard youth performers' healthy development.

Relative Energy Deficiency in Sport (REDs) was first introduced in 2014 by the International Olympic Committee's expert writing panel, identifying a syndrome of deleterious health and performance outcomes experienced by female and male athletes exposed to low energy availability (LEA; inadequate energy intake in relation to exercise energy expenditure). Since the 2018 REDs consensus, there have been >170 original research publications advancing the field of REDs science, including emerging data demonstrating the growing role of low carbohydrate availability, further evidence of the interplay between mental health and REDs and more data elucidating the impact of LEA in males. Our knowledge of REDs signs and symptoms has resulted in updated Health and Performance Conceptual Models and the development of a novel Physiological Model. This Physiological Model is designed to demonstrate the complexity of either problematic or adaptable LEA exposure, coupled with individual moderating factors, leading to changes in health and performance outcomes. Guidelines for safe and effective body composition assessment to help prevent REDs are also outlined. A new REDs Clinical Assessment Tool-Version 2 is introduced to facilitate the detection and clinical diagnosis of REDs based on accumulated severity and risk stratification, with associated training and competition recommendations. Prevention and treatment principles of REDs are presented to encourage best practices for sports organisations and clinicians. Finally, methodological best practices for REDs research are outlined to stimulate future high-quality research to address important knowledge gaps.

Relative Energy Deficiency in Sport (REDs) is common among female and male athletes representing various sports at different performance levels, and the underlying cause is problematic low energy availability (LEA). It is essential to prevent problematic LEA to decrease the risk of serious health and performance consequences. This narrative review addresses REDs primary, secondary and tertiary prevention strategies and recommends best practice prevention guidelines targeting the athlete health and performance team, athlete entourage (eg, coaches, parents, managers) and sport organisations. Primary prevention of REDs seeks to minimise exposure to and reduce behaviours associated with problematic LEA. Some of the important strategies are educational initiatives and de-emphasising body weight and leanness, particularly in young and subelite athletes. Secondary prevention encourages the early identification and management of REDs signs or symptoms to facilitate early treatment to prevent development of more serious REDs outcomes. Recommended strategies for identifying athletes at risk are self-reported screening instruments, individual health interviews and/or objective assessment of REDs markers. Tertiary prevention (clinical treatment) seeks to limit short-term and long-term severe health consequences of REDs. The cornerstone of tertiary prevention is identifying the source of and treating problematic LEA. Best practice guidelines to prevent REDs and related consequences include a multipronged approach targeting the athlete health and performance team, the athlete entourage and sport organisations, who all need to ensure a supportive and safe sporting environment, have sufficient REDs knowledge and remain observant for the early signs and symptoms of REDs.

Objectives: To, based on diagnostic interviews, investigate the distribution of mental disorders among a sample of Norwegian elite athletes with 'at-risk scores' on a self-report questionnaire measuring symptoms of mental health problems. Then, to investigate the relationship between 'at-risk scores' and diagnosed mental disorders. Methods: A two-phase, cross-sectional design was used. In phase 1, 378 elite athletes completed a questionnaire, including validated self-report psychiatric instruments assessing symptoms of mental disorders. In phase 2, we assessed the 30-day presence of the same disorders through diagnostic interviews with the athletes with 'at-risk scores' using the fifth version of the Composite International Diagnostic Interview. Results: Two hundred and eighty athletes (74.1%) had an 'at-risk score,' and 106 of these athletes (37.9%) completed diagnostic interviews. Forty-seven athletes (44.3%) were diagnosed with a mental disorder. Sleep problems (24.5%) and obsessive-compulsive disorder (OCD) and OCD-related disorders (18.9%), mainly represented by body dysmorphic disorder (BDD), were most common. Anxiety disorders (6.6%), eating disorders (5.7%) and alcohol use disorder (≤4.7%) were less frequent. Affective disorders, gambling and drug use disorder were not present. Results from self-report questionnaires did not, in most cases, adequately mirror the number of mental disorders identified using diagnostic interviews. Conclusions: Using self-report questionnaires to map mental distress among elite athletes can be beneficial. If the aim, however, is to investigate mental disorders, one should move beyond self-report questionnaires and use diagnostic interviews and diagnostic instruments. In our study, sleep problems and BDD were the most prevalent. Longitudinal studies are needed to investigate these findings further. © Author(s) (or their employer(s)) 2023.

Background: Mediation analysis is important to test the theoretical framework underpinning an intervention. We therefore aimed to investigate if the healthy body image (HBI) intervention’s effect on eating disorder (ED) symptomatology and use of muscle building supplements was mediated by the change in risk and protective factors for ED development and muscle building supplement use. Methods: This study used data from the HBI intervention: a cluster randomized controlled universal intervention aiming to promote positive body image and embodiment and reduce the risk for ED development including 30 schools in Norway. A total of 1,713 (37% boys) participants were included in the analyses. Conditional latent growth curve analyses were performed to test for indirect effects on ED symptomatology and weekly frequency of protein and creatine supplement use measured at the 12-month follow-up via change in the proposed mediators. Results: In girls, the reduction in ED symptomatology was mediated by positive changes in protective factors (self-esteem and body image flexibility) and reductions in risk factor scores (perceived media pressure and thin appearance internalization). Comparable changes in protective and risk factors among boys played no mediating role. Conclusion: Interventions aiming to reduce the risk of ED development in girls may benefit from aiming to enhance self-esteem and body image flexibility and reduce perceived media pressure and thin appearance internalization. Future studies should investigate the casual relationship between muscle building supplement use and risk and protective factors for ED development in both girls and boys.
