Sex- and age-specific incidence of healthcare-register-recorded eating disorders in the complete swedish 1979-2001 birth cohort.

ABSTRACT:

Objective

To investigate the sex- and age-specific incidence of healthcare-register-recorded anorexia nervosa (AN) and other eating disorders (OED) in a complete birth cohort, and assess whether incidence varies by diagnostic period and (sub-) birth cohort.

Method

We used the actuarial method and Poisson models to examine the incidence of AN and OED from 1987 to 2009 (when individuals were 8-30 years old) for a cohort of 2.3 million individuals (48.7% female) born from 1979 to 2001 in Sweden, identified using Swedish registers.

Results

For both sexes, incidences of AN and OED increased considerably for diagnostic periods after 2000, but differed little by birth cohort. In 2009, AN incidence in the peak age category was 205.9 cases/100,000 persons (95% CI: 178.2, 233.5
