Abstract	Abstract Background Use of dietary supplements (DS) and muscle enhancing dietary supplements (MEDS) is frequent among students despite the lack of evidence of effects and health risks related to consumption. We need to increase our understanding of students’ motivation, examine potential gender differences, and explore explanatory factors, to address preventive measures related to use. Therefore, this study aimed to explore the frequency of, and the reasons for, DS use among university students, as well as explanatory factors for use of MEDS. Method Male and female students from nine Norwegian universities participated in this cross-sectional study. Participants responded to questions about demographics, DS and MEDS use, internalization of body ideals, physical activity- and exercise level, motives for exercise, and exercise context. Independent t-test, Chi-square test, Pearson’s correlation, and logistic regression were used to investigate between group differences, associations, and explanatory factors for use, respectively. P-values ≤ 0.05 were defined as significant. Results A total of 1001 males (34%) and females, with a mean(sd) age of 24.21(4.76) years, participated. The frequency of DS use was 42% and 40% (p = .414) in males and females, respectively, in which more males than females used DS to improve physical or mental performance (p = < .001), increase muscle mass (p = < .001) and weight for health (p = .014), and improve appearance (p = < .001). In males and females, respectively, 25% and 10% used MEDS (p = < .001). In males, being a fitness center member (OR:3.80), exercising to improve muscle mass (OR:1.96), and a higher physical activity level (OR:1.09) positively explained MEDS use, while exercising to increase endurance (OR:0.49) and being an exercise science student (OR:0.47) negatively explained MEDS use. In females, internalizing the athletic body ideal (OR:1.78) and exercising to improve muscle mass (OR:1.74) positively explained MEDS use. Conclusions Our main findings indicate ...

Abstract	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.

Abstract	Abstract Background The Low Energy Availability in Females Questionnaire (LEAF-Q) is a screening tool developed to detect endurance athletes and dancers at risk for development of persistent low energy availability (LEA) and the female athlete triad (Triad). This study investigated the applicability of the LEAF-Q in a cohort of sixty professional female football players. Methods The participants were classified as at risk (≥ 8) or not at risk (< 8) for persistent LEA and the Triad according to their LEAF-Q score, before being compared. Receiver operating curves were then conducted to examine the ability of the overall LEAF-Q and subcategories to correctly determine the presence of clinically defined markers of the Triad. Additionally, Youden’s index was calculated to determine the best fitting cut-off values. Results Thirty-two percent of participants were classified as at risk by the LEAF-Q. We found no statistically significant differences between the two groups for any markers associated with persistent LEA. Except for acceptable accuracy in determining menstrual status, all other LEAF-Q components exhibited poor accuracy and predictive values. Youden’s index scores imply that increasing the overall and injury cut-off values to ≥ 10 and ≥ 5 respectively, would yield increased performance. Conclusions Our findings do not support the use of the LEAF-Q for the purpose of detecting LEA and Triad conditions among female football players.

Abstract	ObjectivesTo enhance knowledge on pregnancy and return to sport in the postpartum period in elite female athletes.Methods34 Norwegian elite athletes (33.1 years) and 34 active controls (31.5 years) were asked about training and competitive history, pregnancy-related issues, injuries, body dissatisfaction (BD), drive for thinness (DT), eating disorders (ED) and practical experiences, through a questionnaire and interview. Independent samples T-tests or χ² tests for between-group differences and paired-samples T-tests and repeated measures analysis of variance for within group differences were used.ResultsNo group differences in fertility problems, miscarriage, preterm birth or low birth weight were found. Both groups decreased training volume all trimesters and the first two postpartum periods compared with prepregnancy, and more athletes returned to sport/exercise at week 0–6 postpartum. We found no group differences in complications during pregnancy and delivery, but athletes reported fewer common complaints. Four athletes experienced stress fracture postpartum. Athletes had higher BD and DT postpartum, while controls reduced DT score. Number of athletes with clinical ED was reduced postpartum, while constant in controls. Athletes were not satisfied with advice related to strength training and nutrition during pregnancy.ConclusionElite athletes and active controls get pregnant easily, deliver healthy babies and decrease training during pregnancy and the first postpartum periods compared with prepregnancy. Most athletes and every third control returned to sport or exercise at week 0–6 postpartum. Athletes report stress fractures and increased BD and DT, but decreased ED postpartum. However, since relatively few athletes were included these findings need further investigation.

Abstract	Abstract Background Body image is considered a core issue for public health and associates with university students’ overall health. Due to positive associations between exercise and body image, it has been suggested that students within an exercise science program might be more body appreciative compared to other students. On the other hand, the strong societal idealization of the athletic body may expose them to a pressure of having a specific body appearance, which may result in unfavorable health consequences. Nevertheless, studies investigating these hypotheses are lacking. We therefore aimed to explore the level and associations of body appreciation, body appearance pressure, body image related mental health constructs, physical activity, and exercise, in Norwegian university exercise science and non-health reference students. Method Male and female exercise science students (n = 517) and reference students (n = 476), from nine large universities in Norway took part in this cross-sectional study. Participants responded to the Body appreciation scale-2, a self-developed questionnaire on body appearance pressure, Physical Appearance Comparison Scale-Revised, Sociocultural attitudes towards appearance questionnaire-4R, Rosenberg Self-Esteem Scale, Satisfaction with Life Scale, and questions about physical activity and exercise. Between group differences were analyzed using student independent t-test and ANCOVA for parametric data and Chi-square test for categorical data, and associations were evaluated by Person’s correlation. P-values ≤0.05 were defined as significant. Results Female exercise science students had higher scores on body appreciation compared to reference students. No group difference was found in males. A high percentage of students reported experiencing body appearance pressure, with 69 and 85% among male and female exercise science students, and 57 and 83% among male and female reference students. Fitness centers were the settings where most respondents experienced body appearance pressure. ...

Abstract	Purpose: Eating disorders (ED) are complex and severe illnesses where evidence-based treatment is needed to recover. However, about half of the patients with ED do not respond to treatments currently available, which call for efforts to expand the portfolio of treatments. The aim of this study was to explore experiences from patients who dropped out of a new treatment for bulimia nervosa and binge ED, combining physical exercise and dietary therapy (PED-t). Methods: We conducted open-ended face-to-face interviews. The interviews were transcribed verbatim and the data were analysed with a phenomenological hermeneutical approach. Results: Three themes emerged: “standing on the outside”, “unmet expectations” and “participation not a waste of time”. Feelings of standing on the outside were elicited by being different from other group members and having challenges with sharing thoughts. Unmet expectations were related to treatment content and intensity, as well as the development of unhealthy thoughts and behaviours. Finally, some positive experiences were voiced. Conclusion: A need to clarify pre-treatment expectations and refining criteria for treatment suitability is indicated. The findings have contributed to the chain of clinical evidence regarding the PED-t and may lead to treatment modifications improving the treatment and thereby reducing drop out.

Abstract	We examined the effects of a 10–14-weeks inpatient lifestyle modification program, including minimum 90 min of physical activity (PA) five days/week, on body composition, CVD risk factors, and eating behavior in 139 obese subjects (BMI 42.6±5.2 kg/m2). Completion rate was 71% (n=71) in the intensive lifestyle intervention (ILI) group and 85% (n=33) among waiting list controls. Compared to controls body weight (-17.0 (95% CI: -18.7, -15.3) kg, P<0.0001), fat mass (-15.2 (95% CI: -17.4, -13.1) kg, P<0.0001), fat free mass (-1.2 (95% CI: -2.2, -0.2) kg, P=0.016) and visceral fat (-86.6(95% CI: -97.4, -75.7) cm2, P<0.0001) were reduced in the ILI-group after 10–14 weeks. Within the ILI-group weight loss was -23.8 (95% CI: -25.9, -21.7) kg, P<0.0001 and -20.3 (95% CI: -23.3, -17.3) kg, P<0.0001, after six and 12 months, respectively. Systolic BP, glucose, triglycerides, and LDL-C were reduced, and HDL-C was increased (all P≤0.006) after 10–14 weeks within the ILI group. The reduction in glucose and increase in HDL-C were sustained after 12 months (all P<0.0001). After one year, weight loss was related to increased cognitive restraint and decreased uncontrolled eating (all P<0.05). Thus, ILI including high volume of PA resulted in weight loss with almost maintenance of fat-free mass, favorable changes in CVD risk factors, and eating behavior in subjects with severe obesity.

Abstract	The purpose of this study was to examine changes in aerobic fitness, muscular strength, bone mineral density (BMD) and body composition during inpatient treatment of underweight and normal weight patients with longstanding eating disorders (ED). Twenty-nine underweight (BMI < 18.5, n = 7) and normal weight (BMI ≥ 18.5, n = 22) inpatients (mean (SD) age: 31.0 (9.0) years, ED duration: 14.9 (8.8) years, duration of treatment: 16.6 (5.5) weeks) completed this prospective naturalistic study. The treatment consisted of nutritional counseling, and 2 × 60 min weekly moderate intensive physical activity in addition to psychotherapy and milieu therapy. Underweight patients aimed to increase body weight with 0.5 kg/week until the weight gain goal was reached. Aerobic fitness, muscular strength, BMD and body composition were measured at admission and discharge. Results showed an increase in mean muscular strength, total body mass, fat mass, and body fat percentage, but not aerobic capacity, among both underweight and normal weight patients. Lumbar spine BMD increased among the underweight patients, no changes were observed in BMD among the normal weight patients. Three out of seven underweight patients were still underweight at discharge, and only three out of nine patients with excessive body fat (i.e., >33%) managed to reduce body fat to normal values during treatment. These results calls for a more individualized treatment approach to achieve a more optimal body composition among both underweight and normal to overweight patients with longstanding ED.

Abstract	The aim of this study was to determine the prevalence of self- reported versus diagnosed stress fractures in female elite athletes and non-athletic controls. A random sample of Norwegian elite athletes from the national teams, aged 13-39 years (n = 186) and a random sample of non-athletic controls (n = 145) in the same age group participated in the study. The athletes represented a junior- or senior team, or a recruiting squad for one of these teams, in one of 46 different sports/events. A higher percentage of athletes self-reported stress fractures (14.0%) compared to those diagnosed with stress fractures (8.1%) (p < 0.001). Six controls self- reported stress fractures, but none of them were diagnosed with stress fractures. These results indicate that self-reporting of stress fractures has low validity. This finding has important implications for further research on stress fractures in athletes
