Anorexia nervosa (AN) is reported to have the highest premature mortality of any psychiatric disorder, but recent meta-analyses may have inflated estimates. We sought to re-estimate mortality after methodological corrections and to identify predictors of mortality. We included 41 cohorts from 40 peer-reviewed studies published between 1966 and 2010. Methods included double data extraction, log-linear regression with an over-dispersed Poisson model, and all-cause and suicide-specific standardized mortality ratios (SMRs), with 95% Poisson confidence intervals. Participants with AN were 5.2 [3.7-7.5] times more likely to die prematurely from any cause, and 18.1 [11.5-28.7] times more likely to die by suicide than 15-34 year old females in the general population. Our estimates were 10% and 49% lower, respectively, than previously reported SMRs. Risk of premature mortality was highest in studies with older participants, although confounding by treatment was present. Gender, ascertainment, and diagnostic criteria also impacted risk.
