|The female athlete triad syndrome has been investigated in high school athletes. The syndrome was first described over 25 years ago and consists of low BMI and low body composition as a result of energy imbalance, menstrual irregularities and bone density abnormalities. The disordered eating and associated stress fractures bring this population of athletes to the attention of sports medicine physicians, orthopaedists and psychiatrists.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
