| Abstract text | INTRODUCTION: In 2023, the International Olympic Committee (IOC) introduced the Relative Energy Deficiency in Sport (REDs) Clinical Assessment Tool Version 2 (CAT2), including a refined four-level traffic light severity/risk stratification, classifying athletes based on presence of various primary and secondary indicators. To ensure equitable and universally applicable REDs diagnostics, CAT2 must be validated in multiple countries, each with their own healthcare frameworks and guideline approaches. OBJECTIVE: The aim of this retrospective cohort study was to evaluate the utility and applicability of the IOC REDs CAT2 in Aotearoa, New Zealand private healthcare setting by prospectively applying the tool amongst females with confirmed clinical diagnoses of REDs. METHODS: Available relevant medical data from 49 (26.6±6.45 years) female patients, who had previously received a clinical diagnosis of REDs from an experienced medical specialist, were applied to the CAT2 to obtain a severity/risk classification (green, yellow, orange or red) based on medical information present in their files. Differences in CAT2 indicators outcomes (categorical and continuous) and availability of data were examined between severity/risk classifications, using Fishers Exact test, one-way analysis of variance and logistical regressions. RESULTS: Twelve percent of patients previously clinically diagnosed with REDs were classified as green according to CAT2 criteria, while the remaining classifications were 45% yellow, 27% orange and 16% red severity. More participants in yellow, orange and/or red classifications had primary/prolonged secondary amenorrhea, secondary amenorrhea, low bone mineral density (BMD) and any menstrual dysfunction (p<0.05) compared to those assigned as a green. Patients classified as red also demonstrated higher prevalence of reported historical clinical eating disorders, high-risk bone stress injury (BSI)/ =2 low-risk BSI, =1 low-risk BSI and any menstrual dysfunction (p<0.05), compared to orange and/or yellow. Interestingly, patients with more CAT2 indicator information available in their clinical notes had greater odds of being classified as red vs yellow risk (OR 4.339, p=0.0039, 95% CI (1.475-21.31)). CONCLUSION: IOC REDs CAT2 demonstrates utility in a New Zealand female population with a prior clinical diagnosis in determining REDs severity/risk classification based on the number and severity of most CAT2 indicators. However, CAT2 severity/risk classifications often depend on clinical information available, meaning athletes could be at risk of being under-classified when CAT2 is applied in a real-world, clinical setting. |
