Certified athletic trainers should be aware that female athletes have an increased risk of developing disordered eating, menstrual disorders, and osteoporosis, the three disorders of the Female Athlete Triad. Objective: This study examined differences between high school and college athletes, and athletes with menstrual irregularities and regularities for disordered eating, BMI, and age of menarche. Design and Setting: Cross-sectional descriptive survey of one NCAA Division III College, 2 Southwestern High Schools. Subjects: A convenience sample of 116 athletes (age=18.61 ± 1.92 years, height=66.2 ± 3.25 inches, mass=143.29 ± 22.82 pounds). Measurements: The independent variables were athletes (college and high school) and menstrual regularity versus irregularity. Menstrual irregularity was defined as cycles not occurring every 21-35 days. A MANOVA examined the effect of high school versus college and menstrual regularity versus irregularity on disordered eating scores, age at menarche, and BMI. A single-sample t-test compared the mean age of menarche to the population mean. An independent samples t-test compared the mean scores of the EAT-26 for athletes with menstrual regularity and irregularity. A pearson correlation identified a relationship between age of menarche and BMI. The Eating Attitudes Test (EAT-26) consisted of 26 questions with a score range of 0 to 78. Results: Twelve out of 116 athletes (10.34%) were classified as having disordered eating. Menstrual irregularity was self-reported by 11 (9.5%) of the athletes. No significant differences were found between high school versus college athletes, and athletes with menstrual irregularity versus regularity for disordered eating, BMI and age of menarche. A significant difference was found (t115=-4.81, p<.001) between the mean age at menarche for the sample (12.21±1.212) when compared to the population value of 12.7. A significant difference was found (t114=-2.044, p<.05) between scores of the EAT-26 for athletes with menstrual irregularity and regularity. A significant negative correlation was found (r114=-.314, p<.01) between BMI and age at menarche, athletes with lower values of BMI experienced later age at menarche. Conclusions: This sample size revealed female athletes still have a prevalence of menstrual irregularity and disordered eating. It is recommended that athletic trainers provide preseason physical screening for menstrual irregularity, refer athletes with disordered eating for treatment, and educate athletes, coaches, and administration on proper nutrition for sports performance.Keyword(s): college level issues, gender issues, high school issues
