Rates and trends in healthcare-detected incidence of anorexia nervosa and bulimia nervosa: A national health insurance claim data study in Taiwan, 2002-2013.

Compared with Western countries, the AN incidence in Taiwan is very low, whereas the BN incidence is in the lower end of the range. The findings that the age of the first-time detected AN and BN is older in Taiwan and that the significant increases in age-specific incidence are mainly among adults suggest that more effort is needed to detect individuals with AN and BN at a younger age in Taiwan.
