Findings From a Comparative Study in SingaporeTAN, SHIAN MING, MD; KWOK, KAH FOO VICTOR, MD; ZAINAL, KELLY A.; LEE, HUEI YEN, MDJournal of Psychiatric Practice®: March 2018 - Volume 24 - Issue 2 - p 97–103 doi: 10.1097/PRA.0000000000000296 ARTICLES Buy Abstract Author InformationAuthors Article MetricsMetrics Objective: The incidence of cases of older onset anorexia nervosa (AN) has increased in recent years. However, the literature on late-onset AN has been inconclusive. The goal of this study was to compare late-onset with early-onset cases of AN. Methods: Cases of AN presenting to an eating disorders treatment service were identified and the associated medical records were studied retrospectively. Results: Of the 577 cases of AN that were studied, 7.1% were late-onset. Unlike the early-onset cases of AN, the late-onset cases reported less teasing and more relationship problems as a trigger for the illness. They were also less likely to join the eating disorders treatment program. Otherwise, the late-onset AN cases were largely similar to the early-onset cases. Conclusions: Although differences exist between early-onset and late-onset cases of AN, these are few. Until stronger evidence emerges over time, there currently seems to be minimal justification to accord late-onset AN a unique position in psychiatric nosology.
