Incidence rates (IRs) per 100,000 were stratified by age, sex, and diagnosis: anorexia nervosa (AN; F50.0\u2009+\u200950.1), bulimia nervosa (BN; F50.2\u2009+\u200950.3), and other EDs (F50.4\u201350.9).

The highest IRs were observed in females aged 15\u201319, followed by females aged 10\u201314 and 20\u201324\u2009years. In 2021, the IR for females aged 15\u201319 was 64.7% higher than expected before declining sharply to 10.9% in 2023, whereas IRs for ages 10\u201314 and 20\u201324 remained approximately 30% higher than expected.
