Author's abstract

This study investigated the desire and its reasons for weight loss, the prevalence of disordered eating patterns and menstrual status, by using written questionnaires and Eating Attitude Test-26 (EAT-26), in Japanese female athletes (n=1000) and nonathletic controls (n=593). Athletes were divided into the following 6 categories: technical (n=84), endurance I (n=84) and II (n=76), aesthetic (n=120), ball-game (n=447), and power sports (n=189). Endurance I consisted of athletes competing in sports where leanness were considered important, while endurance II consisted of athletes competing in sports where leanness is less important. In each catergory, about four fifths of the athletes wanted to reduce their present weight. As to the reasons for weight loss, the athletes, especially those in the categories of endurance I (79%), power (52%) and aesthetic (34%) sports, reported that they prefer to be thin for improving their athletic performance. The prevalence of disordered eating patterns estimated by EAT-26 was significantly higher in the athletes of endurance I (20%) and aesthetic (12%) groups than in the nonathletic controls (3%). In the athletes of these two sporting event categories, higher rates of amenorrhea (endurance I 20% and aesthetic 7% vs. nonathlets 1%) were found to be accompanied by lower values of obesity index and BMI. These data indicate a significantly higher prevalence of disordered eating patterns and menstrual dysfunction in the athletes involved in sports where leanness is emphasized, and a close relationship among undernutrition, low body weight and menstrual dysfunction.
