PURPOSE: Childhood-onset anorexia nervosa (AN) may be under-recognised and under-treated due to atypical presentations. The aims of this study are: (1) describe features of AN in patients ≤ 18 years in an Asian population; and (2) compare childhood-onset and adolescent-onset AN.
METHODS: This study involved a retrospective chart review of patients ≤ 18 years in a Asian population who were treated for anorexia nervosa at the Eating Disorders Service at Singapore General Hospital between Jan 2003 and Dec 2014 (n = 435). Childhood-onset AN was defined as onset < 13 years, while adolescent-onset AN was defined as onset between 13 and 18 years.
RESULTS: Patients were predominantly female (95.4%) and Chinese (83%). The childhood-onset group (8.3%) had mean age of onset 11.5 ± 1.0 years, compared to 15.2 ± 1.6 years for the adolescent-onset group. The childhood and adolescent-onset groups were similar in socio-demographic variables, as well as gender distribution, AN subtype, number of psychiatric comorbidities, family history of psychiatric illness, body image issues and excessive exercise. The childhood-onset group had significantly longer duration of illness prior to presentation (4.75 vs 2.62 years), greater frequency of comorbid obsessive-compulsive disorder (19.4% vs 5.3%) and were more likely to report teasing as a trigger for AN (58.3% vs 31.6%). The childhood-onset group had significantly longer duration of inpatient stay (5.97 vs 3.22 weeks), as well as a greater number of total admissions (2.78 vs 1.37).
CONCLUSION: Our results suggest that cultural factors may impact the development or identification of AN in an Asian context. Possible delay in diagnosis of childhood-onset AN may lead to a more unfavorable clinical course.
LEVEL OF EVIDENCE: Level V, descriptive study.
