Low Energy Availability (Lea) And Its Relationship To Nutritional Status And Bone Health In Collegiate Athletes, Anthony Dempsey
Low Energy Availability (Lea) And Its Relationship To Nutritional Status And Bone Health In Collegiate Athletes, Anthony Dempsey
UNH URC Open (2026 and after)
This project aims to identify low energy availability in a sample of collegiate athletes and explore the relationship with bone mineral density and nutrient deficiencies. Participants (n=3,407) were recruited from a northeast university and self-reported athlete status and physical activity via online questionnaire. Food records were used to calculate energy and nutrient intake. Anthropometrics including height, weight, body composition and bone mineral status were measured in duplicate. Energy availability (EA) was calculated as (Energy Intake (EI) -Exercising Energy Expenditure) (EEE)) /Fat Free Mass (FFM) (kg) and categorized as optimal (>45 kcal/kg FFM), subclinical, or clinically low (< 30 kcal/kg FFM). Fifteen percent of participants were characterized as athletes (club or division I varsity); mean EA was lower among athletes vs. nonathletes (17.90.7vs.21.90.3, p< .001). Males were more likely to have optimal EA status vs. females (8.8vs4.7%, p< .001). Most females (75.1%) were categorized as clinically LEA; 20.3% had subclinical LEA. Among men, athletes’ EA was similar to nonathletes (21.11.2vs22.20.5, p=.4); among females, athletes had lower EA vs. nonathletes (16.220.9vs21.70.3, p< .001). Males with clinically low EA were most likely to consume inadequate intakes of potassium, fiber, iron, and vitamin D (77.1,94.0,10.4 and 97.3%, respectively); similarly, females with clinically low EA, were most likely to consume inadequate intakes (81.9,87.6,88.3, and 99.5%, respectively). Bone z-scores were higher among athletes vs. non athletes (-.27±.06vs-.67±.02, p< .001) but were not different by EA status. Given the prevalence of LEA within the college athlete and nonathlete populations, further research and tailored nutritional education is needed for this at-risk population.
