Summary
Low energy availability (LEA) and Relative Energy Deficiency in Sport (REDs) risk is low in Division II female athletes. Disordered eating, indicated by elevated Eating Disorder Examination Questionnaire (EDE-Q) scores, is a key risk factor for REDs.
Area of Science:
- Sports Medicine
- Exercise Physiology
- Sports Nutrition
Background:
- Low energy availability (LEA) is a risk factor for Relative Energy Deficiency in Sport (REDs) in female athletes.
- Division II collegiate athletes, particularly those in ball sports, may be susceptible to LEA due to energy intake (EI) and exercise energy expenditure (EEE) imbalances.
- Chronic LEA can progress to problematic LEA, increasing the risk of REDs and associated health issues.
Purpose of the Study:
- To assess the prevalence and severity of REDs in Division II female collegiate ball sport athletes.
- To evaluate REDs risk using the REDs Clinical Assessment Tool 2 (CAT2) and the Female Athlete Triad Cumulative Risk Assessment (FAT CRA) tool.
- To identify factors contributing to REDs risk, including disordered eating patterns and physiological markers.
Main Methods:
- Twenty-seven female athletes from volleyball, soccer, basketball, and rugby participated.
- Data collected included demographics, injury history, depression, eating disorders (EDs), Eating Disorder Examination Questionnaire (EDE-Q), Low Energy Availability in Females Questionnaire (LEAF-Q), and dual X-ray absorptiometry (DXA).
- REDs risk was determined using the REDs CAT2 Tool and Triad risk using the FAT CRA.
Main Results:
- 85.2% of athletes presented with no or low risk of REDs, while 15% had mild risk.
- An elevated EDE-Q score was more prevalent in athletes with mild REDs risk (p<0.001).
- Global and shape concerns on the EDE-Q were strongly associated with increased REDs risk (rs(25)=0.61, p<0.001; rs(25)=0.6, p<0.001).
Conclusions:
- REDs risk was generally low in this cohort of Division II female ball sport athletes.
- Elevated EDE-Q global scores, indicating disordered eating, were the most significant indicator of REDs risk.
- Disordered eating risk appears to be as influential as physiological markers in identifying athletes at risk for REDs.
