    Abstract:
    OBJECTIVE: To determine sex differences in refeeding (i.e., short-term nutritional rehabilitation) outcomes among hospitalized adolescents and young adults with eating disorders. METHODS: We retrospectively reviewed electronic medical records of 601 patients aged 9-25 years admitted to the University of California, San Francisco Eating Disorders Program for medical and nutritional management between May 2012 and August 2020. Descriptive statistics, crude, and adjusted linear regression models were used to assess the association between sex and nutritional outcomes and predictors of length of stay. RESULTS: A total of 588 adolescents and young adults met eligibility criteria (16% male, mean [SD] age 15.96  [2.75], 71.6% anorexia nervosa, admission percent median body mass index [%mBMI] 87.1 ± 14.1). In unadjusted comparisons, there were no significant sex differences in prescribed kilocalories (kcal) per day at admission (2013 vs. 1980, p = .188); however, males had higher estimated energy requirements (EER, kcal) (3,694 vs. 2,925, p < .001). In linear regression models adjusting for potential confounders, male sex was associated with higher prescribed kcals at discharge (B = 835 kcal, p < .001), greater weight change (B = 0.47 kg, p = .021), and longer length of stay (B = 1.94 days, p = .001) than females. Older age, lower admission weight, lower prescribed kcal at admission, higher EER, and lower heart rate at admission were factors associated with longer length of stay in a linear regression model. DISCUSSION: These findings support the development of individualized approaches for males with eating disorders to improve quality of care and health care efficiency among an underserved population.
