Abstract
Aims: To investigate the prevalence and psychosocial correlates of eating disorders (EDs) among Taiwanese population, and to evaluate relative performance of the EAT and the BITE as a screening tool for EDs. Methods: The study subjects consisted of all female high school students who were enrolled in the gifted dance class in the whole nation and non-dance female students randomly chosen from the same school. Students were asked to complete self-report questionnaires, including two screening instruments (EAT-26 and BITE), and two other questionnaires (BSQ and BSRS), as well as demographic details at phase-one survey. Phase-two participants consisted of all the screen positives for either one criteria or an approximate 10 % random sample from the screen negatives for both criteria. Every phase-two participant was interviewed with SCID to establish ED diagnoses in the past one year, and was asked to complete the Family APGAR scale. Results: The prevalence of individual ED was higher in the dance class students than that in the non-dance class students. The prevalence of bulimia nervosa was comparable to that of Western countries, in contrast to the low prevalence of anorexia nervosa among Taiwanese young girls. Under such context, the BITE had better accuracy than the EAT in detecting cases with EDs. Higher concern in body shape and lower family support were common psychosocial correlates of EDs for both groups of students. While lower parental education was associated with a higher risk of developing EDs for the non-dance class students, distinctive features were associated with EDs for the dance students, i.e., those who are overweight, have emotional disturbance, and have relatives with weight reduction practices. Conclusion: The EDs were more prevalent in weight-concern subpopulation. Bulimia nervosa was more prevalent than anorexia nervosa, and was in a similar rate to that of Western countries. The BITE was a valid screening tool for detecting cases of EDs in the community samples.
