Exercise program within adult psychiatric inpatient services for those with disordered eating

INTRODUCTION & AIMS Over one million Australians live with an eating disorder, with 40 – 80% reported to undertake dysfunctional exercise practices (e.g., compulsive exercise, exercise dependence). Dysfunctional exercise can be the first symptom to appear and the last symptom to resolved in eating disorder patients, with 41% of eating disorders patients relapsing into dysfunctional exercise patterns 4 to 9 months post inpatient treatment. We evaluated an accredited exercise physiology led program implemented for adult mental health inpatients with disordered eating and exercise behaviours to support patient outcomes and safe exercise participation. METHODS Data was collected as part of service evaluation and included patient characteristics, session data (e.g., mood and enjoyment via Exercise Enjoyment Scale) and patient outcomes (e.g., Compulsive Exercise Test (CET); Exercise Dependence Scale (EDS-21)). Characteristics of the cohort was reported and compared to clinical cut-offs, along with program feasibility measures. RESULTS Between Sep 2022 and Nov 2023, 20 female patients engaged in the program (mean age= 26 years). Of those 15 were diagnosed with Anorexia Nervosa, 16 with a co-occurring Personality Disorder and 9 with a Trauma Related Disorder. EDS-21 results showed 56% were symptomatic, and 33% exercise dependent, with 80% also presenting with suicidal ideation/self-harm. Across 137 service interactions, patients engaged 65% of the time, and 25% of the time deemed inappropriate. Pre-session mood was low (mean= -2.13 ± 1.46) with an average post-session mood improvement of + 4.46 Session enjoyment was high (mean=3.6±1.20) and no adverse events were recorded. CONCLUSIONS & IMPLICATIONS Exercise supported by AEPs is safe for inpatients with disorder eating, with patients valuing engagement in services focused on supporting positive exercise relationships and behaviours. A tailored and evidence-based approach to exercise can improve acute mood of consumers.
