title: A high exercise load is linked to pathological weight control behavior and eating disorders in female fitness instructors.
abstract: Demographic data, exercise habits, weight control behavior, attitudes towards body shape, eating disorder (ED) experience, and menstrual regularity among female fitness instructors were descriptively assessed. A 60-item questionnaire was sent to 295 female fitness instructors at eight fitness centers. Responders (57%) reported a mean weekly exercise load of 5.5 h week(-1) (SD 2.6), which indicates frequent training, however, less than that of athletes. Overall, 35% reported ED experience (DSM-IV criteria), with an onset at 15-17 years of age. The problems had lasted 5-7 years, and 20% of the entire group reported recovery, however, 11% still had EDs. For the entire group, it was found that a high weekly exercise load was linked to a pathological weight control behavior. Fitness instructors with an active ED exercised more than instructors who never had an ED or who had a past ED. Menstrual irregularity was more common among instructors who did not use contraceptives (14%), compared to those who did (5%). As ED experience and pathological weight control behavior were common in the studied group, the importance of guidelines regarding communication from female fitness instructors about healthy training habits to regular exercisers is discussed in the article.
