Whitelaw M, et al. - Researchers conducted retrospective (2005–2010) and prospective (2011–2013) studies to determine the contribution of weight loss to complications experienced in restrictive eating disorders (EDs). For this purpose, they compared total weight loss (from lifetime maximum) and recent weight loss (past 3 months) with admission weight as predictors of physical and psychological complications in 12- to 19-year-old hospitalized adolescents with anorexia nervosa (AN) or AAN, characterized as meeting criteria for AN except underweight (≥85% median body mass index). Greater total weight loss and greater recent weight loss were related to a lower pulse rate nadir but not admission weight. A higher incidence of bradycardia was also associated with greater total weight loss and greater recent weight loss. Total weight loss and recent weight loss in adolescents with restrictive EDs were better predictors than admission weight of many physical complications.
