A brief examination of treatment outcomes in higher levels of care for individuals with eating disorders across age groups

Objective: Although eating disorders (EDs) occur throughout the lifespan, little research has been conducted with midlife/older adults, particularly those in higher levels of care (HLOC). The current study examined outcomes among 2009 patients with EDs receiving HLOC treatment at a large multisite facility between January 2020 and June 2022, across different age groups (ages <18, 18-25, 26-39 and >= 40). It was hypothesised that patients aged 40+ would exhibit less improvement on measures of ED psychopathology and depression than other age groups.Method: Participants completed the eating disorder examination-questionnaire (EDE-Q) and the patient health questionnaire-9 (PHQ-9) at admission and discharge.Results: Changes for all outcomes from admission to discharge were statistically significant at p < 0.001 across all age groups. Changes in the EDE-Q Restraint subscale were significantly less in patients ages 26-39 than in patients ages 18-25 (p < 0.01). Changes in PHQ-9 were significantly greater in patients ages 40+ than patients ages 18-25 (p = 0.03).Conclusions: Contrary to hypotheses, patients ages 40+ did not show worse outcomes than younger patients, and showed greater improvements in depression than young adults. The therapeutic needs of midlife/older adults with EDs may be favourably met by a HLOC regimen as described in this study.
