Iron Deficiency and Anemia in Male and Female Adolescent Athletes Who Engage in Ball Games.

The aim of this study was to assess the prevalence of iron deficiency (ID) and iron deficiency anemia (IDA) among male adolescent athletes who participate in non-calorie-restricting sports, and to compare the results with female athletes of the same age and sports. Data of the hemoglobin concentration (Hb) and serum ferritin (sFer) levels of male (n = 350) and female (n = 126) basketball and football players, aged 11-18, from two sport medicine centers in Israel were gathered and analyzed. Mild ID was defined as sFer ≤ 30 µg/L, moderate as sFer ≤ 20 µg/L, and severe as sFer ≤ 10 µg/L. IDA was defined as sFer ≤ 20 µg/L and Hb < 13 g/dL for males and sFer ≤ 20 µg/L and Hb < 12 g/dL for females. The prevalence of mild ID was 41.1% and 53.2%, moderate was 17.4% and 27.8%, and severe was 2% and 4.8% in males and females, respectively. The prevalence of IDA was 2.6% in males and 4% in females. Mild and moderate ID was significantly higher among females. In conclusion, non-anemic ID, which is known to be common among female athletes, especially in sports requiring leanness, is also highly prevalent among adolescent males playing ball games. Therefore, screening for hemoglobin and sFer is recommended for young athletes of both genders and in all sports.

[RECOMMENDATIONS FOR CHANGING CARDIOVASCULAR SCREENING OF ATHLETES WHO ARE REQUIRED FOR PRE-PARTICIPATION SCREENING UNDER THE SPORTS LAW - A POSITION PAPER ON BEHALF OF THE ISRAEL HEART SOCIETY].

INTRODUCTION: For many years routine screening of athletes in Israel includes frequently performed ECGs and exercise tests that overload the system with questionable benefits. The purpose of the current document is to reevaluate the need for pre-participation testing and establish new evidence-based guidelines. It should be noted that our proposal for a change of approach relates only to subjects whose health questionnaire is normal, who do not have a family history of sudden and unexpected death at an early age, or a family history of hereditary heart disease and whose physical examination from a cardiovascular point of view is normal.

Medical students as health coaches: Implementation of a student-initiated Lifestyle Medicine curriculum.

BACKGROUND: By 2020, the World Health Organization predicts that two-thirds of all diseases worldwide will be the result of lifestyle choices. Physicians often do not counsel patients about healthy behaviors, and lack of training has been identified as one of the barriers. Between 2010 and 2014, Hebrew University developed and implemented a 58-h Lifestyle Medicine curriculum spanning five of the 6 years of medical school. Content includes nutrition, exercise, smoking cessation, and behavior change, as well as health coaching practice with friends/relatives (preclinical years) and patients (clinical years). This report describes this development and diffusion process, and it also presents findings related to the level of acceptance of this student-initiated Lifestyle Medicine (LM) curriculum. METHODS: Students completed an online semi-structured questionnaire after the first coaching session (coaching questionnaire) and the last coaching session (follow-up questionnaire). RESULTS: Nine hundred and twenty-three students completed the coaching questionnaire (296 practices were with patients, 627 with friends /relatives); and 784 students completed the follow-up questionnaire (208 practices were with patients, 576 with friends /relatives). They reported overall that health coaching domains included smoking cessation (263 students), nutrition (79), and exercise (117); 464 students reported on combined topics. Students consistently described a high acceptance of the curriculum and their active role in coaching. Further, most students reported that they were eager to address their own health behaviors. CONCLUSIONS: We described the development and acceptance of a student-initiated comprehensive LM curriculum. Students perceived LM as an important component of physicians' professional role and were ready to explore it both as coaches and in their personal lives. Thus, medical school deans might consider developing similar initiatives in order to position medical schools as key players within a preventive strategy in healthcare policy.

Changes in fitness are associated with changes in body composition and bone health in children after cancer.

AIM: This study examined the effects of physical activity on the fitness, body composition and mental health of children after cancer or bone marrow transplantation. METHODS: We focused on 22 children aged from seven to 14 years who had received chemotherapy and/or bone marrow transplantation in our medical centre. Ten children took part in a six-month exercise programme, and 12 children who did not exercise formed the control group. At baseline and at the end of the trial, we measured aerobic fitness, body composition, bone density and assessed the child's mood and quality of life. We pooled all participants together post hoc to compare changes in fitness with the various study outcomes. RESULTS: We found no differences between groups in changes in fitness, body composition or mental health indices. Significant correlations were found between changes in aerobic fitness and changes in lean body mass (r = 0.74, p = 0.002), bone mineral content (r = 0.57, p = 0.026) and femoral neck bone mineral density (r = 0.59, p = 0.027) in all participants. CONCLUSION: Group-based exercise training did not improve aerobic fitness in children after cancer or bone marrow transplantation. However, changes in fitness throughout the study period were associated with changes in body composition and bone health in all participants.

[Aerobic fitness and cardiorespiratory function of pediatric cancer survivors].

INTRODUCTION: Overall, more than 80% of children diagnosed with cancer will survive their immediate disease. This growing group of childhood cancer survivors is at an increased risk for several chronic diseases and increased mortality. Physical activity is a well-known and powerful means to reduce such complications, yet many children are not active as recommended. Furthermore, the complex treatments might adversely affect the heart and lungs, possibly limiting physical performance. AIM: To measure aerobic fitness among childhood cancer survivors, while assessing maximal cardiac and respiratory functions. METHODS: Eighteen children (mean age 11.5 +/- 2.1 years, 50% males) who had completed medical treatment for cancer, and 16 healthy children, performed a cardiorespiratory exercise test on a bicycle ergometer until exhaustion. Peak oxygen uptake, O2 pulse and several ventilatory parameters were measured and compared between the groups. RESULTS: The mean maximal load obtained by the cancer survivor group was lower than expected, compared with controls (89% +/- 19 vs. 101/% +/- 18, p = 0.055). Peak oxygen consumption was also lower, with a marginal statistical significance (33.3 +/- 7.5 vs. 38.9 +/- 9.7 ml O2/kg/min, p = 0.075), yet was significantly lower when expressed as a percent of age- and sex- appropriate norms [78% +/- 15 vs. 94% +/- 16, p = 0.0081. Cardiac and respiratory functions were normal in all children, with no between-group differences. CONCLUSIONS: We conclude that aerobic fitness is lower in children who have survived cancer, with no evidence of significant cardiac or lung damage. Given the importance of regular physical activity for this at-risk population, it should be continuously encouraged, while administering a personally tailored exercise prescription.

[Who will take care of the caretaker? Lifestyle recommendations for physicians].

A healthy lifestyle is the mainstay of preventive medicine. HeaLthcare personnel might disregard keeping a healthy diet and exercise habits, perhaps due to feeling protected by their own knowledge. Physicians might under-diagnose their own overweight status, and have been shown in some studies to display lower rates of healthy behaviors compared with the general population. This review presents the availabLe data on physicians' own lifestyle habits, and discusses the importance of these for both their own health, and for the benefit of their patients. We supply several healthy lifestyle recommendations based on national and international guidelines, and adapt them to the clinic and hospital settings. Eating a healthy diet, and performing at least 150 minutes of aerobic exercise a week, with additional resistance exercises 2-3 times a week, will benefit all caretakers--both personally and professionally.

[Childhood obesity--assessment, prevention and treatment].

As in other parts of the western world, the rates of pediatric overweight and obesity are also rising in Israel. This fact warrants immediate action by several government offices and health care providers, and also by the trinity of physician, parent(s) and child. An overweight child is likely to remain undiagnosed if relying on observation alone, unless height and weight are objectively measured by the caring medical staff. This review is based on recommendations on the assessment, prevention, and treatment of children and youth who are overweight and obese, recently published on behalf of the American Medical Association and additional health organizations. In general, preventing and treating pediatric obesity is fairly similar: adhering to a healthy lifestyle which emphasizes healthy food choices and habits, regular physical activity, and limiting screen time. Treating and preventing obesity is a timely, but extremely difficult task. Medical personnel and parents should be continuously educated in this field, while supplied with practical tools for childhood lifestyle modification.

Prevalence of iron depletion and anemia in top-level basketball players.

Iron depletion, with or without anemia, may have a negative effect on physical and mental performance. Even with current recognition of the problem, its incidence among athletes remains high. Most studies describe iron status in endurance athletes. This study examined the prevalence of iron depletion and anemia among male and female top-level basketball players. Adolescents and adults (N = 103) from 8 national basketball teams were screened for anemia and iron stores status, which included a complete blood count and levels of plasma ferritin, transferrin, and serum iron. Iron depletion, defined by a ferritin level below 20 microg/L, was found among 22% of study participants (15% in males vs. 35% in females, p = .019). Anemia was found among 25% of athletes (18% in males vs. 38% in females, p = .028). Iron deficiency anemia, defined by the presence of anemia, ferritin levels below 12 microg/L, and transferrin saturation below 16%, was found among 7% of players (3% in males vs. 14% in females, p = .043). In summary, a high prevalence of iron depletion, anemia, and iron deficiency anemia was found among basketball players of both genders. We recommend screening ballgame players for blood count and iron store status, and providing nutritional counseling and iron supplementation when necessary.
