Aim: To explore if the longer-term outcome and mortality is different in males and females treated for anorexia nervosa (AN) or bulimia nervosa (BN). Methods: Using the questionnaires SIAB-S, EDI, BSI 119 males and 119 matched females with AN, and 60 males and 60 matched females with BN were assessed at follow-up 6 to 8 years later. Crude mortality rates (CMR) and standardized mortality ratios (SMR) were computed for 147 (AN) and 81 (BN) males. Preliminary results: AN: 22% of the males and 31% of the females still had AN at FU (n.s.). 3% of the AN males and 8% of the AN females crossed over to BN (n.s.), and 34 % of the AN males and 19 % of the AN females had EDNOS (χ2 (1)=6.6; p<.01). Remission rate for AN was 40 % for males and 41 % for females (n.s.). BN: 17 % of the BN males and 22 % of the BN females still had BN at follow-up. 3% of the BN males and 2 % of the BN females crossed to AN and 34 % of the BN males and 27 % of the BN females had EDNOS. Remission rate for BN was 44 % in males and 50 % in females (n.s.). In the EDI and BSI subscales males tended to have lower scores than females. SMR was 4.93 (95% CI 2.36-9.07) for AN males and 5.29 (4.32-6.40) for AN females; it was 1.42 (0.39-3.63) for BN males and 1.57 (1.15-2.09) for BN females. Conclusions: Although at follow-up, males and females differed in some subscales of the EDI and BSI longer-term outcome for AN and BN males and females is surprisingly similar with slight tendencies for better outcome in males.
