Relative Energy Deficiency in Sport-Multidisciplinary Treatment in Clinical Practice.

BACKGROUND/OBJECTIVES: The primary aim of this study was to characterize athletes approaching an outpatient interdisciplinary and multidisciplinary consultation structure for athletes with a suspected relative energy deficiency in sport (REDs) cross-sectionally and longitudinally to prove treatment efficacy.

METHODS

Data of 58 athletes suspected of REDs were collected at the onset (t) and completion (t) of interdisciplinary and multidisciplinary REDs treatment (clinical practice) between January 2019 and December 2022. The data included extracted information from medical records, anthropometric characteristics, physical performance diagnostics, laboratory values, dietary records, and partially gynecological and psychosomatic diagnostics.

RESULTS

The sample primarily consisted of female athletes (97%) under 18 years of age (66%) who were underweight with a body mass index (BMI) < 18.5 kg/m and BMI percentile below the 10th percentile for their age and gender-specific norms (59%), and experienced menstrual disorders (93%). The dietary behavior is characterized by plant-based and low-energy-dense foods. Eating disorders (anorexia nervosa and bulimia nervosa) were diagnosed in 40% of the athletes according to the International Statistical Classification of Diseases and Related Health Problems 11th revision criteria. During the program, 64% of the athletes exhibited a mean weight gain of 7 (±6) kg ( < 0.001), excluding those still undergoing treatment (36%).

CONCLUSIONS

The proposed interdisciplinary and multidisciplinary treatment approach proved effective and holds promise for future evidence-based developments in REDs treatment.
