Eating disorders and weight control behaviors change over a collegiate sport season

Smartphone Addiction and Related Factors among Athletes

Smartphone addiction (SA) is increasing worldwide. The aim of this study is to determine the level of SA in athletes affiliated to the Turkish Handball Federation in Izmir and to examine its relationship with factors such as sociodemographic status, health status, eating attitude, and body perception. This cross-sectional study was conducted in March-April 2021 in Izmir Province. The sample of the study consisted of 212 licensed handball athletes. The short SA scale, three-factor nutrition scale, and body perception scale were used. A chi-square test was used for bivariate comparisons and logistic regression analysis was used for multivariate comparisons. The study was completed with 202 individuals (the coverage rate was 95.3%). The prevalence of SA was found to be 27.7%. The risk of SA increased 2.49-fold (CI: 1.17-5.31, p = 0.018) in female participants, 2.01-fold (CI: 1.01-4.06, p = 0.048) in participants with alcohol use, 2.17-fold (CI: 1.04-4.58, p = 0.042) in participants with low nutritional scores, 2.65-fold (CI: 1.15-6.10, p = 0.022) in individuals with high-income status, and 2.66-fold (CI: 1.07-6.64, p = 0.036) in individuals with high body perception scale score. In total, 27.7% of the athlete sample had scores above the SA threshold. These results point out that a behavioral addiction such as SA can occur even in professionals of an activity such as sports, known for beneficial effects in terms of healthy life.

A systematic review, meta-analysis, and meta-regression of the prevalence of self-reported disordered eating and associated factors among athletes worldwide

BACKGROUND

The purpose of this meta-analysis was to provide a pooled prevalence estimate of self-reported disordered eating (SRDE) in athletes based on the available literature, and to identify risk factors for their occurrence.

METHODS

Across ten academic databases, an electronic search was conducted from inception to 7th January 2024. The proportion of athletes scoring at or above predetermined cutoffs on validated self-reporting screening measures was used to identify disordered eating (DE). Subgroup analysis per country, per culture, and per research measure were also conducted. Age, body mass index (BMI), and sex were considered as associated/correlated factors.

RESULTS

The mean prevalence of SRDE among 70,957 athletes in 177 studies (132 publications) was 19.23% (17.04%; 21.62%), I2 = 97.4%, τ2 = 0.8990, Cochran's Q p value = 0. Australia had the highest percentage of SRDE athletes with a mean of 57.1% (36.0%-75.8%), while Iceland had the lowest, with a mean of 4.9% (1.2%-17.7%). The SRDE prevalence in Eastern countries was higher than in Western countries with 29.1% versus 18.5%. Anaerobic sports had almost double the prevalence of SRDE 37.9% (27.0%-50.2%) compared to aerobic sports 19.6% (15.2%-25%). Gymnastics sports had the highest SRDE prevalence rate, with 41.5% (30.4%-53.6%) while outdoor sports showed the lowest at 15.4% (11.6%-20.2%). Among various tools used to assess SRDE, the three-factor eating questionnaire yielded the highest SRDE rate 73.0% (60.1%-82.8%). Meta-regression analyses showed that female sex, older age, and higher BMI (all p < 0.01) are associated with higher prevalence rates of SRDE.

CONCLUSION

The outcome of this review suggests that factors specific to the sport affect eating behaviors throughout an athlete's life. As a result, one in five athletes run the risk of developing an eating disorder. Culture-specific and sport-specific diagnostic tools need to be developed and increased attention paid to nutritional deficiencies in athletes.

Risk factors for eating disorders: findings from a rapid review

BACKGROUND

Risk factors represent a range of complex variables associated with the onset, development, and course of eating disorders. Understanding these risk factors is vital for the refinement of aetiological models, which may inform the development of targeted, evidence-based prevention, early intervention, and treatment programs. This Rapid Review aimed to identify and summarise research studies conducted within the last 12 years, focusing on risk factors associated with eating disorders.

METHODS

The current review forms part of a series of Rapid Reviews to be published in a special issue in the Journal of Eating Disorders, funded by the Australian Government to inform the development of the National Eating Disorder Research and Translation Strategy 2021-2031. Three databases were searched for studies published between 2009 and 2021, published in English, and comprising high-level evidence studies (meta-analyses, systematic reviews, moderately sized randomised controlled studies, moderately sized controlled-cohort studies, or population studies). Data pertaining to risk factors for eating disorders were synthesised and outlined in the current paper.

RESULTS

A total of 284 studies were included. The findings were divided into nine main categories: (1) genetics, (2) gastrointestinal microbiota and autoimmune reactions, (3) childhood and early adolescent exposures, (4) personality traits and comorbid mental health conditions, (5) gender, (6) socio-economic status, (7) ethnic minority, (8) body image and social influence, and (9) elite sports. A substantial amount of research exists supporting the role of inherited genetic risk in the development of eating disorders, with biological risk factors, such as the role of gut microbiota in dysregulation of appetite, an area of emerging evidence. Abuse, trauma and childhood obesity are strongly linked to eating disorders, however less conclusive evidence exists regarding developmental factors such as role of in-utero exposure to hormones. Comorbidities between eating disorders and mental health disorders, including personality and mood disorders, have been found to increase the severity of eating disorder symptomatology. Higher education attainment, body image-related factors, and use of appearance-focused social media are also associated with increased risk of eating disorder symptoms.

CONCLUSION

Eating disorders are associated with multiple risk factors. An extensive amount of research has been conducted in the field; however, further studies are required to assess the causal nature of the risk factors identified in the current review. This will assist in understanding the sequelae of eating disorder development and in turn allow for enhancement of existing interventions and ultimately improved outcomes for individuals.

Intermittent fasting implementation and association with eating disorder symptomatology

Intermittent fasting (IF) is an emerging dietary trend that remains understudied. This study aimed to describe the implementation and eating disorder (ED) symptomatology, relevant to engagement in IF among both men and women. Intermittent fasters (N = 44 women, N = 20 men) recruited from Amazon Mechanical Turk, Reddit, and a Midwestern University were administered a demographic questionnaire, an assessment of ED symptomatology (Eating Disorder Examination Questionnaire; EDE-Q), and asked about their IF use. To assess the level of ED symptomatology among individuals using IF community and clinical norms were used for comparison. We hypothesized a) men and women engaging IF would score higher on the EDE-Q and b) more individuals engaging in IF would endorse ED behaviors (e.g., self-induced vomiting) than community norms. Intermittent fasters reported fasting for approximately 16 hours daily and for weight loss purposes. Men and women engaging in IF scored significantly higher than community norms on all subscales of the EDE-Q, with 31.25% of participants' EDE-Q scores being at or above the clinical EDE-Q cut-off. Men and women engaging in IF reported engaging in ED behaviors. Results suggest that IF is associated with ED symptomatology. Further research on psychological characteristics and temporal order of the association between IF and ED symptomatology is warranted.

Health outcomes among former female collegiate gymnasts: the influence of sport specialization, concussion, and disordered eating

Objective: Gymnastics is a popular sport with high injury rates, especially at the collegiate level. There is limited evidence, however, regarding the risks of early specialization in this sport, the rate of concussions in gymnasts, and the long-term effects of disordered eating in gymnasts. We sought to describe health-related outcomes of former collegiate gymnasts and the association with early sport specialization, concussion history, and disordered eating.Methods: We distributed an online survey through social media outlets. A total of 473 former female collegiate gymnasts completed the survey and were grouped according to early (<14 years) specialization, presence or absence of concussion history, and history of disordered eating. We determined the number of participants who had time-loss injuries, injuries requiring surgery, and injuries resulting in retirement. We also evaluated menstrual history, reasons for sport retirement, functional outcome measures, and mental health.Results: The median age of gymnastics specialization was 8 years [interquartile range = 6-11 years]. The proportion of injuries sustained during college did not significantly differ by specialization age. A significantly greater proportion of early specializers required surgery for college sports-related injuries (60% vs. 44%; p = 0.02). Forty-two percent of the respondents reported concussion history, and a greater proportion of those with concussion history reported seeking mental health treatment during college (32% vs. 23%; p = 0.03), and anxiety disorder diagnosis (16% vs. 9%; p = 0.01). Disordered eating history was reported by 34% of the respondents, and this group had a higher proportion of time-loss injury (78% vs 65%; p = 0.004), and osteoporosis (4% vs 0%; p = 0.003) during college, and worse current pain (11.5 vs 10.2; p = 0.007) and physical function (12.2 vs 11.0; p = 0.01) than those without disordered eating.Conclusion: Athletes and clinicians should be aware of the long-term effects of early specialization, concussions, and disordered eating in gymnastics as these issues are common in female collegiate gymnasts.

Body Composition, Dietary Intake and the Risk of Low Energy Availability in Elite-Level Competitive Rhythmic Gymnasts

The aim of this study was to analyze dietary intake and body composition in a group of elite-level competitive rhythmic gymnasts from Spain. We undertook body composition and nutritional analysis of 30 elite gymnasts, divided into two groups by age: pre-teen (9-12 years) (n = 17) and teen (13-18 years) (n = 13). Measures of height, weight, and bioimpedance were used to calculate body mass index and percent body fat. Energy and nutrient intakes were assessed based on 7-day food records. The two groups had similar percentages of total body fat (pre-teen: 13.99 ± 3.83% vs. teen: 14.33 ± 5.57%; p > 0.05). The energy availability values for pre-teens were above the recommended values (>40 kcal/FFM/day) 69.38 ± 14.47 kcal/FFM/day, while those for the teens were much lower (34.7 ± 7.5 kcal/FFM/day). The distribution of the daily energy intake across the macronutrients indicates that both groups ingested less than the recommended level of carbohydrates and more than the recommended level of fat. Very low intakes of calcium and vitamin D among other micronutrients were also noted. The main finding is that teenage gymnasts do not consume as much energy as they need each day, which explains their weight and development. Moreover, they are at a high risk of developing low energy availability that could negatively impact their performance and future health.

Nutritional Status and Implementation of a Nutritional Education Program in Young Female Artistic Gymnasts

Adolescent high-performance gymnasts are considered to be at risk for low energy intake. The aim of the present study was to determine the effects of implementing a nutritional education program during the sports season on the nutritional status and nutrition knowledge of the female artistic gymnasts from the Technification Center of the Balearic Islands (n = 24; age, 14.1 ± 2.3 years). A quasi-experimental intervention design was applied, which consisted of implementing a nutritional education program of seven sessions given during eight months. Measurements of nutritional intake, nutrition knowledge, and anthropometric parameters, as well as hematological and biochemical blood parameters, were performed. Gymnasts reported low energy and carbohydrate intakes, with significant increases during the study (energy, 28.3 ± 1.4 vs. 32.8 ± 1.4 kcal kg⁻¹, p = 0.015, carbohydrate 3.2 ± 0.2 vs. 3.9 ± 0.2 g kg⁻¹, p = 0.004). The average values for parameters such as hemoglobin, ferritin, lipoprotein, and vitamin C and E levels in the plasma were within normal ranges. Low intakes of most of the food groups were observed during the study, with similar initial and final values. Nutrition knowledge did not change as a result of the study (28.0 ± 1.7 vs. 31.1 ± 1.3, p = 0.185). In conclusion, gymnasts reported low energy intakes. However, blood markers and most of the anthropometrical parameters measured were within normal ranges. The nutrition education program implemented did not produce significant improvements in the dietary habits or nutritional knowledge of gymnasts.

Eating disorder diagnosis and the female athlete: A longitudinal analysis from college sport to retirement

OBJECTIVES

Female athletes experience eating disorders (EDs) at clinical, and subclinical, levels; most studies have determined point-prevalence rates through cross-sectional methodologies. To date, few studies have examined the long-term stability of EDs in female athletes; none extend into retirement.

DESIGN

A longitudinal investigation of ED classification (i.e., Clinical ED, Subclinical ED, Healthy) and weight control behaviors (e.g., vomiting, laxative use) from when athletes actively competed (T1) into their retirement (T2).

METHODS

Participants included U.S. female athletes (N=193) who were collegiate competitors (T1) and eventually were retired from their collegiate sports six years later (T2).

RESULTS

At T2, athletes were classified as Healthy (69.9%), Subclinical ED (26.9%), and Clinical ED (3.1%). Overall percentage of Subclinical EDs increased from 18.7% (T1) to 26.9% (T2); 52.8% of T1 Subclinical ED athletes continued to meet criteria for either Subclinical or Clinical ED at T2. Of the 13 Clinical ED athletes at T1, six (46.2%) continued to meet criteria for either a subclinical or clinical ED at T2. Though exercising (2+ hours/day; n=8, 4.1%) and dieting/fasting (4+ times/year; n=14, 7.3%) were the most frequently used weight control behaviors at T2, rates were substantially lower than at T1.

CONCLUSIONS

Retirement does not result in immediate remittance of eating concerns among female athletes; many continue or develop Subclinical and Clinical ED symptoms. Thus, addressing healthy body image and nutrition when athletes are competing is imperative to assist prevention and intervention efforts that may alleviate ED symptoms as athletes transition from sport.

Group and longitudinal intra-individual networks of eating disorder symptoms in adolescents and young adults at-risk for an eating disorder

Several studies have identified risk factors that predict future onset of eating disorders (ED) in adolescence, however, it is currently unknown how specific ED symptom dynamics operate both across time and within individuals. Advances in network methodologies allow for the study of how dynamic symptoms interrelate and predict each other within-persons and across time. In the current study, we used longitudinal group-level (N = 1272) (addressing symptom interrelations across people and across time; between-subjects, contemporaneous, and temporal networks) and intra-individual (symptom interrelations within each person and across time; contemporaneous and temporal networks) network analyses (subset n = 50) in prospective 48-month interview data in at-risk adolescents and young adults. We computed between-subject networks (how symptoms are associated on average, for group sample only), contemporaneous networks (how symptoms are associated at one time point, accounting for previous time points), and temporal networks (examining how symptoms predict each other across time). We replicated prior network results which suggest that overvaluation of weight and shape are central in at-risk adolescents and young adults. We found that individual networks (n = 1 networks) were highly variable across individuals. Overall, our results show how both group-level and longitudinal intra-individual network analysis can inform our understanding of how EDs develop in adolescence and point to the importance of conceptualizing development on an individual level of analysis.

Help-Seeking for Eating Pathology Among Collegiate Athletes: Examining Stigma and Perfectionism as Moderating and Mediating Mechanisms

Despite elevated risk of eating pathology (EP) among athletes, utilization of EP-treatment among athletes is low. Factors that may inhibit EP-help-seeking among athletes include perceived social stigma, self-stigma, and perfectionism. Heightened stigma associated with EP and sport climates may be exacerbated by negative perfectionism characteristic of athletes and decrease intentions to seek help for EP. We tested the following moderated-mediation model among a sample of collegiate athletes (N = 201) via online questionnaires: EP indirectly relates to EP help-seeking intentions through perceived and self-stigma and these relations are conditional on negative perfectionism. EP help-seeking intentions were negatively associated with EP severity, stigma, and negative perfectionism. EP was related to eating-specific help-seeking intentions through perceived social stigma, influencing self-stigma, but this was not moderated by negative perfectionism. Targeting mental-health treatment stigma among athletes may reduce risk of untreated EP among collegiate athletes.

Body Image Concern and Eating Disorder Symptoms Among Elite Icelandic Athletes

The aim of this study was to analyse body image concerns and symptoms of eating disorders in elite Icelandic athletes according to their sex, and sport practiced. The participants were 755 athletes (24.8 ± 3.5 years in age) who compete at the highest possible level in Iceland. Representing 20 different sports, they were divided into five sports groups. Three questionnaires were used: the Body Shape Questionnaire to assess body image concerns; the Bulimia Test-Revised to assess the main symptoms of bulimia; and the Eating Disorder Examination Questionnaire to identify disordered eating attitudes and behaviours. A chi-squared test was used to analyse differences in prevalence of body image concern and eating disorders, a t-test for the differences between men and women, and a one-way ANOVA to compare the different sports. The main findings were that 17.9% of the athletes presented severe or moderate body image dissatisfaction, and 18.2% (25.3% of the women) were above the clinical cutoff for body image concern. Women’s scores were higher than men’s (whole sample and ball games) in all variables except restraint. These results seem to point to the existence of a real problem that athlete, coaches, doctors, and institutions need to take into account.

Mental health in elite athletes: International Olympic Committee consensus statement (2019)

Mental health symptoms and disorders are common among elite athletes, may have sport related manifestations within this population and impair performance. Mental health cannot be separated from physical health, as evidenced by mental health symptoms and disorders increasing the risk of physical injury and delaying subsequent recovery. There are no evidence or consensus based guidelines for diagnosis and management of mental health symptoms and disorders in elite athletes. Diagnosis must differentiate character traits particular to elite athletes from psychosocial maladaptations.

Management strategies should address all contributors to mental health symptoms and consider biopsychosocial factors relevant to athletes to maximise benefit and minimise harm. Management must involve both treatment of affected individual athletes and optimising environments in which all elite athletes train and compete. To advance a more standardised, evidence based approach to mental health symptoms and disorders in elite athletes, an International Olympic Committee Consensus Work Group critically evaluated the current state of science and provided recommendations.

Essentials for Best Practice: Treatment Approaches for Athletes With Eating Disorders

Eating disorders (EDs) and disordered-eating behaviors (DEBs), pose a high risk of morbidity and mortality, threatening physical health, emotional health, and overall quality of life. Unfortunately, among athletes, prevalence rates continue to increase. This document summarizes the challenges of establishing and navigating the multidisciplinary care needed to effectively treat EDs and DEBs among athletes. The benefits of timely and frequent communication within the multidisciplinary treatment team (MDTT) are emphasized and discussed. Authors advise who should be selected as members of the MDTT and suggest that all personnel, including athletic coaches, athletic trainers, physical therapists, and certified fitness professionals be ED-informed and ED-sensitive. Vital components of care are noted including use of a variety of evidence-based psychotherapeutic modalities, interventions which target emotional regulation, and prioritize values based compassionate care. Authors caution that performance decrements and medical/physiological changes are not always easily observable in individuals with EDs and DEBs and therefore, attuned, consistent, and ongoing monitoring is needed. Consensus regarding previously established parameters for return to play and careful titration of physical activity throughout the ED recovery process are suggested as important for preserving health, preventing re-injury, or relapse and facilitating successful return to sport participation.
