Knowledge of the Female Athlete Triad and Relative Energy Deficiency in Sport Among Female Cross-Country Athletes and Support Staff.

CONTEXT: Female endurance athletes exhibit an increased risk of the female athlete triad (Triad) and relative energy deficiency in sport (RED-S). The triad and RED-S are conditions that involve the health and performance consequences of low energy availability. Few authors of studies to date have assessed the knowledge that athletes, coaches, and athletic trainers (ATs) have regarding the Triad or RED-S. Proper education has been shown to be effective in increasing knowledge of sports medicine concerns for athletes, yet no known continuing education programs for the Triad or RED-S exist at collegiate institutions. OBJECTIVE: To assess the knowledge, confidence, and educational impact of identifying, screening, treating, and preventing the Triad or RED-S. DESIGN: Cross-sectional study. SETTING: An evidence-based online survey was developed and administered via Qualtrics. PATIENTS OR OTHER PARTICIPANTS: Female collegiate cross-country athletes (n = 275, age = 20 ± 1 years), collegiate cross-country coaches (n = 55, age = 34 ± 9 years), and ATs working with cross-country teams (n = 30, age = 36 ± 11 years). MAIN OUTCOME MEASURE(S): Knowledge, confidence, and educational impact scores were assessed among groups using analysis of variance. Independent t tests were calculated to determine differences in impact scores between people who had or had not received education on the topic. RESULTS: Female cross-country athletes' total knowledge, confidence, and educational impact scores (mean scores = 25.00 ± 5.27, 95.42 ± 28.83, and 18.81 ± 7.05, respectively) were different from those of coaches (mean scores = 26.92 ± 5.02, 111.35 ± 24.14, and 22.41 ± 6.33, respectively) and ATs (mean scores = 28.66 ± 4.02, 117.67 ± 22.53, and 23.93 ± 5.69, respectively; P < .05). CONCLUSIONS: Knowledge, confidence, and educational impact scores regarding Triad or RED-S were lowest in female cross-country athletes and highest in ATs. These findings support the call for education, which should be regarded as the primary tool for increasing knowledge, to improve the prevention and treatment of the Triad or RED-S.

Disordered Eating, Development of Menstrual Irregularity, and Reduced Bone Mass Change After a 3-Year Follow-Up In Female Adolescent Endurance Runners.

This prospective study evaluated the 3-year change in menstrual function and bone mass among 40 female adolescent endurance runners (age 15.9 ± 1.0 years) according to baseline disordered eating status. Three years after initial data collection, runners underwent follow-up measures including the Eating Disorder Examination Questionnaire and a survey evaluating menstrual function, running training, injury history, and prior sports participation. Dual-energy X-ray absorptiometry was used to measure bone mineral density and body composition. Runners with a weight concern, shape concern, or global score ≥4.0 or reporting >1 pathologic behavior in the past 28 days were classified with disordered eating. Compared with runners with normal Eating Disorder Examination Questionnaire scores at baseline, runners with disordered eating at baseline reported fewer menstrual cycles/year (6.4 ± 4.5 vs. 10.5 ± 2.8, p = .005), more years of amenorrhea (1.6 ± 1.4 vs. 0.3 ± 0.5, p = .03), and a higher proportion of menstrual irregularity (75.0% vs. 31.3%, p = .02) and failed to increase lumbar spine or total hip bone mineral density at the 3-year follow-up. In a multivariate model including body mass index and menstrual cycles in the past year at baseline, baseline shape concern score (B = -0.57, p value = .001) was inversely related to the annual number of menstrual cycles between assessments. Weight concern score (B = -0.40, p value = .005) was inversely associated with lumbar spine bone mineral density Z-score change between assessments according to a multivariate model adjusting for age and body mass index. These finding support associations between disordered eating at baseline and future menstrual irregularities or reduced accrual of lumbar spine bone mass in female adolescent endurance runners.

Performance and Health Decrements Associated With Relative Energy Deficiency in Sport for Division I Women Athletes During a Collegiate Cross-Country Season: A Case Series.

The purpose of this case series was to evaluate the presence of low Energy Availability (EA) and its impact on components of Relative Energy Deficiency in Sport (RED-S) in a population of female collegiate runners. Seven female NCAA Division I athletes (age: 22.3 ± 1.5 yrs; height: 169.7 ± 5.7 cm; weight: 58.3 ± 4.1 kg) were tracked from August until February, covering the beginning (Pre XC), end (Post XC) of their competitive cross country season, and beginning of the following track season (Pre Track). The athletes were assessed for female athlete triad (Triad) risk, energy availability, body composition, resting metabolic rate (RMR), nutritional intake, and blood markers (including vitamin D, ferritin, and triiodothyronine (T3)). From Pre XC to Post XC there were no significant differences in body mass, fat free mass or body fat percentage. At Pre XC, mean EA was 31.6 ± 13.3 kcal/kg FFM∙d-1. From Post XC to Pre Track, there was a significant increase in body mass (59.1 ± 5.1 to 60.6 ± 5.7 kg, p<0.001,d=0.27). From Post XC to Pre Track, there was a significant increase in RMR (1466 ± 123.6 to 1614.6 ± 89.1 kcal·d-1, p<0.001,d=2.6). For 25(OH) vitamin D, there was a significant reduction from Pre XC to Post XC (44.1 ± 10.6 vs 39.5 ± 12.2 ng·mL-1, p=0.047,d=-0.4), and a significant increase from Post XC to Pre Track (39.5 ± 12.2 vs. 48.1 ± 10.4 ng·mL-1, p=0.014,d=0.75). For ferritin, there was a trend towards a decrease from Pre XC to Post XC (24.2 ± 13.2 vs. 15.7 ± 8.8 ng·mL-1, p=0.07, d=-0.75), as well as a trend toward an increase from Post XC to Pre Track (15.7 ± 8.8 vs. 34.1 ± 18.0 ng·mL-1, p=0.08, d=1.3). No differences in T3 were observed across time points. Average Triad risk score was 2.3 ± 1.4. Notably, 5 of 7 athletes met criteria for moderate risk. Despite many athletes meeting criteria for low EA and having elevated Triad risk assessment scores, most were able to maintain body mass and RMR. One athlete suffered severe performance decline and a reduced RMR. Surprisingly, she was the only athlete above the recommended value for ferritin. Following increased nutritional intake and reduced training volume, her performance and RMR recovered. Changes in body mass and body composition were not indicative of the presence of other concerns associated with RED-S. This exploratory work serves as a guide for future, larger studies for tracking athletes, using RMR and nutritional biomarkers to assess RED-S.

Sports and Metabolic Bone Disease.

Physical activity (PA) increases bone mass and bone strength through different mechanisms and also reduces the risk of falls in the elderly, through proprioception and balance training. The benefits seen in adolescence continue into adulthood. Exercise delays and attenuates the effects of osteoporosis, and particular sports activities may be recommended to improve bone mineral density (BMD) of the spine or regional BMD, improve balance, and prevent falls. Stress injuries related to exercise are more common in osteopenic and osteoporotic individuals.Sports activity may in some cases be detrimental for bone health, with nutrition restriction a frequent cause for negative effects of the practice of PA on bone. The examples are the so-called female athlete triad of menstrual dysfunction resulting in reduced estrogen levels, low energy due to malnutrition, and decreased BMD. A similar triad is described in male athletes. This review analyzes the effects of sport on bone metabolism and in particular its relationship with metabolic bone disease.

Exploring Health Demographics of Female Collegiate Rowers.

CONTEXT: Limited information exists about health patterns among female rowers at the collegiate level. Furthermore, the element of weight class (lightweights classified as <130 lb [59 kg]) as a factor in the physical and mental health of female collegiate athletes has not been investigated, despite weight requirements in sport being a risk factor for the female athlete triad. OBJECTIVE: To test the hypotheses that (1) components of the female athlete triad were more prevalent in lightweight than in openweight rowers; (2) perceived stress levels were greater in lightweight than in openweight rowers; and (3) rowers who were unable to row due to injury had greater perceived stress levels than uninjured athletes. DESIGN: Cross-sectional study. SETTING: Twelve collegiate women's rowing programs consisting of 6 National Collegiate Athletic Association Division I openweight and 6 Intercollegiate Rowing Association-level lightweight teams. PATIENTS OR OTHER PARTICIPANTS: A total of 158 female collegiate rowers (78 lightweight, 80 openweight). MAIN OUTCOME MEASURE(S): An electronic survey addressing injury history, diet and eating habits and body image (according to the triad screening questionnaire), stress levels (Perceived Stress Scale), and athlete identity (Athlete Identity Measurement Scale) was administered. RESULTS: Lightweight rowers reported limiting or carefully controlling foods more frequently than openweight rowers (41.9% to 29.9%, P = .013). A history of an eating disorder was more prevalent among lightweight than openweight rowers (25.7% to 13.0%, P = .048). Prevalences of stress fractures and menstrual irregularities did not differ between weight classes. Lightweight and openweight rowers' scores on the Perceived Stress Scale (16.0 ± 9.9 and 17.3 ± 6.4, respectively) were not different. Injured rowers scored higher on the Perceived Stress Scale (19.4 ± 7.2) than did uninjured rowers (16.6 ± 5.72). CONCLUSIONS: Weight class did not contribute to differences in the prevalence of female athlete triad components or perceived stress, although lightweight rowers were more likely to have a history of eating disorder. Injury may be a risk factor for increased stress in this population.

Hypogonadism in Exercising Males: Dysfunction or Adaptive-Regulatory Adjustment?

For decades researchers have reported men who engaged in intensive exercise training can develop low resting testosterone levels, alterations in their hypothalamic-pituitary-gonadal (HPG) axis, and display hypogonadism. Recently there is renewed interest in this topic since the International Olympic Committee (IOC) Medical Commission coined the term "Relative Energy Deficiency in Sports" (RED-S) as clinical terminology to address both the female-male occurrences of reproductive system health disruptions associated with exercise. This IOC Commission action attempted to move beyond the sex-specific terminology of the "Female Athlete Triad" (Triad) and heighten awareness/realization that some athletic men do have reproductive related physiologic disturbances such as lowered sex hormone levels, HPG regulatory axis alterations, and low bone mineral density similar to Triad women. There are elements in the development and symptomology of exercise-related male hypogonadism that mirror closely that of women experiencing the Triad/RED-S, but evidence also exists that dissimilarities exist between the sexes on this issue. Our research group postulates that the inconsistency and differences in the male findings in relation to women with Triad/RED-S are not just due to sex dimorphism, but that there are varying forms of exercise-related reproductive disruptions existing in athletic men resulting in them displaying a relative hypogonadism condition. Specifically, such conditions in men may derive acutely and be associated with low energy availability (Triad/RED-S) or excessive training load (overtraining) and appear transient in nature, and resolve with appropriate clinical interventions. However, manifestations of a more chronic based hypogonadism that persists on a more permanent basis (years) exist and is termed the "Exercise Hypogonadal Male Condition." This article presents an up-to-date overview of the various types of acute and chronic relative hypogonadism found in athletic, exercising men and proposes mechanistic models of how these various forms of exercise relative hypogonadism develop.

Female Athlete Triad and Relative Energy Deficiency in Sport: A Focus on Scientific Rigor.

We examine the scientific evidence supporting The Female Athlete Triad and Relative Energy Deficiency in Sport (RED-S) syndromes. More research is necessary to advance the understanding of both syndromes; however, it is premature to consider RED-S as an evidence-based syndrome. Future research should specifically define RED-S components, determine its clinical relevance, and establish the causality of relative energy deficiency on RED-S outcomes.

The Female Athlete Triad: A Comparison of Knowledge and Risk in Adolescent and Young Adult Figure Skaters, Dancers, and Runners.

STUDY OBJECTIVE: The female athlete triad is often found in sports that value leanness and aesthetics and can lead to adverse health effects. We aimed to compare knowledge and risk of the triad among adolescent figure skaters, dancers, and runners. DESIGN, SETTING, PARTICIPANTS, AND MAIN OUTCOME MEASURES: We advertised our survey on social media platforms: sports-specific forums; Facebook; and Instagram. We received 928 responses. We included female figure skaters, dancers, and runners aged 25 years or younger (N = 712). We asked participants to name the triad components and dichotomized knowledge scores as high or low. We developed a 6-question triad risk scale and defined "at risk" if participants endorsed 3 or more questions. RESULTS: Of 712 participants: 60% were figure skaters; 28% dancers; 12% runners; 78% were adolescents (≤17 years of age); 22% young adults (18-25 years); 12% had heard of the triad. A higher proportion of runners than figure skaters and dancers had high knowledge of the triad (16% vs 6% vs 5%, P < .01). Overall 60% of athletes were "at risk" of the triad, 25% skipped a period for 3 or more months, and 34% had a history of stress fractures or shin splints. Young adults vs adolescents and dancers vs figure skaters and runners had nearly twice the odds of triad risk. CONCLUSION: Most athletes were at risk of the triad but few knew about it. Dancers were at higher risk compared with figure skaters and runners. Efforts should be made to raise awareness of the triad among athletes, parents, and coaches, with special attention paid to the dance community.

Sleep duration, body composition, dietary profile and eating behaviours among children and adolescents: a comparison between Portuguese acrobatic gymnasts.

Sleep, body composition and dietary intake are crucial for athletes' health and performance but have never been investigated in acrobatic gymnasts. Thus, this study aimed to evaluate sleep, body composition, dietary intake and eating behaviours of acrobatic gymnasts. Using a cross-sectional study, 82 Portuguese acrobatic gymnasts (12.8 ± 3.1 years, 61 females and 21 males) were evaluated during the competitive period to collect training data, sleep duration, body composition, dietary intake and eating behaviours before, during and after practices. Most of the gymnasts (91.5%) slept less than 8 h/night. Female adolescents slept significantly less on weekdays than female children (P = 0.024). Female adolescents' mean body mass was below the normal and 60.0% showed menstrual irregularities; 4.9% of females bases were overweight and 2.4% obese. Male adolescents slept significantly less on weekdays than male children (P = 0.001); significant differences were shown for fat-free mass (P = 0.014); however, 3.7% were overweight. All daily energy and macronutrient intakes were significantly different according to age and gender, with exception for fibre and energy intake in females (P = 0.057 and P = 0.052, respectively), and for protein in males (P = 0.068). Female and male adolescents demonstrated significant lower energy availability (32.8 ± 9.4 kcal/kg FFM/day and 45.1 ± 14.7 kcal/kg FFM/day) than children (45.8 ± 8.7 kcal/kg FFM/day and 53.8 ± 9.1 kcal/kg FFM/day), respectively. Significant low intakes of important vitamins and minerals were reported. Most of the participants did not eat or drink during or immediately after training sessions. CONCLUSION: Acrobatic gymnasts revealed low BF, short sleep duration and macro- and micronutrients inadequate intakes. The Female Athlete Triad was demonstrated by female adolescent gymnasts. What is Known: • Adequate dietary intake is an important resource for athletes' short and long-term health and performance. • There are no published studies in acrobatic gymnasts' sleep, body composition or dietary intake. What is New: • This study provides the first data on significant differences in energy intake and availability between acrobatic gymnasts; overweight and obesity were present in females. • Macro and micronutrients were inappropriate. Female Athlete Triad was observed in female adolescent acrobatic gymnasts.

Reduced energy availability: implications for bone health in physically active populations.

PURPOSE: The present review critically evaluates existing literature on the effects of short- and long-term low energy availability (EA) on bone metabolism and health in physically active individuals. METHODS: We reviewed the literature on the short-term effects of low EA on markers of bone metabolism and the long-term effects of low EA on outcomes relating to bone health (bone mass, microarchitecture and strength, bone metabolic markers and stress fracture injury risk) in physically active individuals. RESULTS: Available evidence indicates that short-term low EA may increase markers of bone resorption and decrease markers of bone formation in physically active women. Bone metabolic marker responses to low EA are less well known in physically active men. Cross-sectional studies investigating the effects of long-term low EA suggest that physically active individuals who have low EA present with lower bone mass, altered bone metabolism (favouring bone resorption), reduced bone strength and increased risk for stress fracture injuries. CONCLUSIONS: Reduced EA has a negative influence on bone in both the short- and long-term, and every effort should be made to reduce its occurrence in physically active individuals. Future interventions are needed to explore the effects of long-term reduced EA on bone health outcomes, while short-term low EA studies are also required to give insight into the pathophysiology of bone alterations.

A tríade da atleta / The female athlete triad

A Tríade da Atleta (TA) é uma síndrome que se manifesta na mulher por meio da baixa disponibilidade de energia (com ou sem distúrbios alimentares), disfunção menstrual e baixa densidade mineral óssea (DMO). Geralmente, acomete pessoas envolvidas com a prática de atividades físicas que enfatizam o emagrecimento.(1,2,3) O diagnóstico pode ser feito por meio da análise do Índice de Massa Corporal (IMC) da paciente; pelo cálculo da disponibilidade de energia; exames de densitometria óssea e radiografia da coluna vertebral, associados à presença de menstruações infrequentes ou amenorreia no ciclo menstrual da paciente. A incidência da TA vem aumentando na atualidade devido à maior divulgação dos benefícios da prática esportiva e à preocupação excessiva com a estética corporal imposta pela sociedade em que vivemos. Os profissionais da saúde devem estar aptos a detectar precocemente os sinais da TA para dar início ao tratamento, uma vez que este é o fator mais importante para diminuir as severas consequências ao organismo.(3) O presente artigo tem como objetivo informar sobre a existência dessa síndrome, com destaque para os métodos diagnósticos e o tratamento.(AU)

The Athlete Triad (AT) is a syndrome that is manifested in women through low energy availability with or without eating disorders, menstrual dysfunction and low bone mineral density (BMD). Usually affects people involved in physical activities that emphasize weight loss. (1,2,3) The diagnosis can be made through the patient's Body Mass Index (BMI) analysis; by calculating the availability of energy; examination of bone densitometry and radiography of the spine associated with infrequent periods or amenorrhea in the patient's menstrual cycle. The incidence of AT is increasing today because the dissemination of sports benefits and excessive concern with body imposed by society. Health professionals must be able to detect early signs of AT to start the treatment, because is the most important factor to reduce the severe consequences on the body.(3) This article has the objective to inform health professionals about the existence of this syndrome with emphasis on diagnostic methods and treatment tools.(AU)

Association of the Female Athlete Triad Risk Assessment Stratification to the Development of Bone Stress Injuries in Collegiate Athletes.

BACKGROUND: The female athlete triad (referred to as the triad) contributes to adverse health outcomes, including bone stress injuries (BSIs), in female athletes. Guidelines were published in 2014 for clinical management of athletes affected by the triad. PURPOSE: This study aimed to (1) classify athletes from a collegiate population of 16 sports into low-, moderate-, and high-risk categories using the Female Athlete Triad Cumulative Risk Assessment score and (2) evaluate the predictive value of the risk categories for subsequent BSIs. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A total of 323 athletes completed both electronic preparticipation physical examination and dual-energy x-ray absorptiometry scans. Of these, 239 athletes with known oligomenorrhea/amenorrhea status were assigned to a low-, moderate-, or high-risk category. Chart review was used to identify athletes who sustained a subsequent BSI during collegiate sports participation; the injury required a physician diagnosis and imaging confirmation. RESULTS: Of 239 athletes, 61 (25.5%) were classified into moderate-risk and 9 (3.8%) into high-risk categories. Sports with the highest proportion of athletes assigned to the moderate- and high-risk categories included gymnastics (56.3%), lacrosse (50%), cross-country (48.9%), swimming/diving (42.9%), sailing (33%), and volleyball (33%). Twenty-five athletes (10.5%) assigned to risk categories sustained ≥1 BSI. Cross-country runners contributed the majority of BSIs (16; 64%). After adjusting for age and participation in cross-country, we found that moderate-risk athletes were twice as likely as low-risk athletes to sustain a BSI (risk ratio [RR], 2.6; 95% confidence interval [95% CI], 1.3-5.5) and high-risk athletes were nearly 4 times as likely (RR, 3.8; 95% CI, 1.8-8.0). When examining the 6 individual components of the triad risk assessment score, both the oligomenorrhea/amenorrhea score ( P = .0069) and the prior stress fracture/reaction score ( P = .0315) were identified as independent predictors for subsequent BSIs (after adjusting for cross-country participation and age). CONCLUSION: Using published guidelines, 29% of female collegiate athletes in this study were classified into moderate- or high-risk categories using the Female Athlete Triad Cumulative Risk Assessment Score. Moderate- and high-risk athletes were more likely to subsequently sustain a BSI; most BSIs were sustained by cross-country runners.

Increasing training load without risking the female athlete triad: menstrual cycle based periodized training may be an answer?

BACKGROUND: An improved muscle strength are of great importance in many sports, hence an increased understanding on how to generate optimal strength training programs in women without negative side effects that may lead to the female athlete triad are essential. The purpose of this study was to investigate potential negative effects of high frequency periodized menstrual/oral contraceptives (OC) cycle based leg resistance training on components in the female athlete triad. METHODS: Fifty-nine women, with experience of resistance training and with regular menstrual/OC cycles were included in the analyses. The participants were randomly assigned a training program consisted of high frequency leg resistance training, periodized to the first two weeks (group 1) or the last two weeks (group 2) of each cycle, or to a control group performing regular training, during four consecutive menstrual/OC cycles. The main analysis was the pre-to-post change of sex and growth hormones, cortisol, total body fat mass, bone mineral density in the spine. We further examined the participants' own experience of the training programs. RESULTS: No significant negative impact on sex and growth hormones, cortisol, total body fat mass and bone mineral density in the spine, was detected in any of the groups. Moreover, the women in group 1 experienced their training program as positive. CONCLUSIONS: The high frequency periodized leg resistance training was not associated with exercise-related negative consequences on components in the female athlete triad. Moreover, the training was well accepted when performed during the first two weeks of each cycle.

Amenorrhea in the Female Athlete: What to Do and When to Worry.

Functional hypothalamic amenorrhea is a diagnosis of exclusion that is common in female athletes, particularly those participating in aesthetic sports (ballet, other dance genres, figure skating, and gymnastics) and endurance sports (cross-country running). Although common, it should be considered abnormal even in the high-level elite athlete. Amenorrhea in combination with low energy availability and low bone density is labeled "the Female Athlete Triad." Studies have demonstrated numerous long-term consequences of athletes suffering from all or a portion of this triad, including increased rate of musculoskeletal injuries, stress fractures, abnormal lipid profiles, endothelial dysfunction, potential irreversible bone loss, depression, anxiety, low self- esteem, and increased mortality. This article provides the clinician with the tools to evaluate an athlete with secondary amenorrhea, reviews the recommended treatment options for affected athletes, and discusses when to return to the activity in an effort to facilitate "healthy" participation.

Knowledge of the female athlete triad, and prevalence of triad risk factors among female high school athletes and their coaches.

STUDY OBJECTIVE: This study aimed to determine awareness/knowledge of the Triad and its health implications among female high school athletes and their coaches, and to evaluate coaches' Triad screening/intervention practices. DESIGN: Cross-sectional survey. SETTING: Two high schools in the western United States. PARTICIPANTS: Female athletes from a variety of sports (N = 240) ages 14-18 years and their coaches (N = 10). INTERVENTION: Participants completed surveys that assessed Triad knowledge and athlete Triad risk factors. MAIN OUTCOME MEASURES: Frequency of responses to Triad knowledge, Triad risk factor, and Triad education/screening procedures questions; athlete summative knowledge score. RESULTS: Half (N = 120) of participants reported menstrual irregularity, and 42% (N = 101) had 2 or more Triad risk factors: past amenorrhea (N = 39), past stress fracture (N = 41), self-reported not eating enough (N = 53), underweight (BMI-for-age < 5(th) percentile) (N = 10), pressure to be a certain weight (N = 143), and wanting to lose >10 pounds when self-reported weight was in a healthy range (N = 34). Average athlete Triad knowledge score was 2.97 ± 1.61 out of 8. Coach Triad knowledge was limited; however, most (9/10) were comfortable discussing menstruation with their athletes. Barriers to Triad screening/education were coaches' insufficient time, knowledge, and educational resources. CONCLUSION: Triad risk factors were prevalent among athletes and coach and athlete Triad knowledge was low. Providing coaches with Triad screening/education training may increase Triad knowledge and decrease Triad risk among high school athletes.

Disordered eating among adolescent female swimmers: dietary, biochemical, and body composition factors.

OBJECTIVE: To verify associations among body composition, biochemical parameters, and food intake in adolescent female swimmers with and without disordered eating (DE). METHODS: Seventy-seven athletes 11 to 19 y old from clubs in Rio de Janeiro, Brazil were studied. DE was assessed through three questionnaires (Eating Attitudes Test-26; Bulimic Investigatory Test, Edinburgh; and Body Shape Questionnaire), body composition by dual-energy x-ray absorptiometry, and food intake by a 3-d diet record. Biochemical parameters related to iron, folic acid, and vitamin B12 were analyzed. The Fisher exact test, Mann-Whitney test, and the Spearman coefficient were calculated. RESULTS: DE was found in 44.2% of the sample. DE-positive compared with DE-negative athletes presented greater body fat percentage (11-14 y: 27.5% versus 23.4%, P = 0.023; 15-19 y: 30.2% versus 24.1%, P = 0.006) and fat mass (11-14 y: 13.8 versus 10.3 kg, P = 0.010; 15-19 y: 17.0 versus 13.2 kg, P = 0.027). In relation to food intake, DE-positive athletes presented lower protein consumption in the 11- to 14-y-old group and lower calcium intake adequacy in the 15- to 19-y-old group. Most other dietary parameters showed a low adequacy of consumption, with no difference between athletes with and without DE. Four DE-positive athletes presented anemia or iron deficiency. CONCLUSION: DE-positive compared with DE-negative athletes presented a higher percentage of body fat and fat mass, lower protein consumption in the 11- to 14-y-old group, and lower calcium intake adequacy in the 15- to 19-y-old group. Greater attention should be given to the nutritional state of these athletes, considering the number of adolescents with anemia and an inadequate dietary intake.

The female athlete triad.

The Female Athlete Triad poses serious health risks, both short and long term, to the overall well-being of affected individuals. Sustained low energy availability can impair health, causing many medical complications within the skeletal, endocrine, cardiovascular, reproductive, and central nervous systems. With the surge of females participating in athletics within the past 10 to 15 years, it is both conceivable and likely that the prevalence of this syndrome will continue to grow. Therefore, it is imperative that appropriate screening and diagnostic measures are enacted by a multidisciplinary team of health care providers, counselors, teachers, and dieticians in order to provide the proper care to affected athletes. Initial awareness should take place within the educational confines of elementary and high schools. Screening for female athletes exhibiting risk factors for the triad should also take place at the time of sports physicals. If one component of the triad is identified, the clinician should take the time to effectively workup the other 2. Treatment for each component of the triad includes both pharmacological and nonpharmacological measures, with emphasis placed upon increased energy availability and overall improved nutritional health. Using this all-encompassing type of approach, sports medicine practitioners should feel empowered to continue to promote the lifelong well-being of female athletes in the years to come.

[Increased morbidity risk in female athletes]. / Risiko for øget sygelighed hos kvindelige idraetsudøvere.

The female athlete triad refers to the interrelationships among energy availability, menstrual function and bone mineral density which may have clinical manifestations including eating disorders, functional hypothalamic amenorrhea and osteoporosis. The potentially irreversible consequences of these clinical conditions emphasize the critical need for prevention, early diagnosis and treatment. Nutritionally correct food ensuring optimal energy balance is a premise to improve these conditions. Alternative treatment is oestrogen replacement therapy which can prevent progressive bone loss.
