This study aimed to evaluate nutrient intake, eating patterns, and bone mass in male collegiate runners with and without disordered eating (DE). Ninety-two male collegiate endurance runners from two NCAA Division I cross-country and track and field programs completed a baseline survey evaluating demographic characteristics, dietary restraint and pathologic behaviors, exercise training, and related health behaviors. Runners also underwent a pre-participation physical exam, one-on-one dietitian meeting including a 24-hour dietary recall, and completed an online survey evaluating food intake and eating patterns. DE was evaluated during the annual preparticipation exam and dietary restraint and pathologic behavior questions from the Eating Disorder Examination Questionnaire were utilized. The Mann-Whitney U and Chi-square tests evaluated between-group differences. Of 92 athletes (age= 19.8 ± 1.4y; BMI= 21.2 ± 1.5 kg/m2), running on average 60.8 ± 17.2 miles/week, 13% (n=12) met criteria for disordered eating. No differences were identified between runners based on DE status for age, BMI, weekly running volume, and running pace. A subset of runners (n=20) had complete data for energy availability (EA); 35% (n=7) had an EA <30.0 kcal/kgFFM/day. The one runner with DE and EA assessment exhibited an EA of 27.9 kcal/kgFFM/day, compared to 42.2 ± 23.1 kcal/kgFFM/day in the non-DE group. A higher proportion of runners meeting the criteria for DE failed to meet carbohydrate intake recommendations (6-10 g/kg/day) and trended towards lower intake of carbohydrates compared to runners not classified with DE (4.5 ± 0.7 vs. 6.2 ± 2.0, p= 0.065). Dietary fat and protein intake did not significantly differ between groups. More runners with, compared to without, DE met criteria for low bone mineral density (BMD) (BMD Z-score < -1.0) (66.7% vs. 11.8%, p= 0.01) and exhibited lower lumbar spine BMD Z-scores (-1.17 ± 0.45 vs. -0.25 ± 0.81, p= 0.03). Male runners with DE are at an increased risk of inadequate carbohydrate intake and low BMD. Findings from this study suggest that a subset of males, like females, are susceptible to DE and subsequent health outcomes. Future research should aim to clarify patterns of disordered eating in male runners, relationships with energy availability, and risk of low BMD.
