目的：探討暴食症在臺北市某二所高中與高職學生之盛行率。另外，透過性格量表與家庭關懷度量表的同時施測，以進一步探討暴食症的人格與社會等相關因素。方法：採問卷調查法，對象為台北市某高中與某高職之非畢業班之學生，問卷包括暴食問卷（BITE）、簡式性格量表與家庭關懷度量表。共有160名高職男生、1153名高職女生、603名高中男生與584名高中女生完成問卷。另有27名參加暴食症團體治療之飲食疾患病人也全部或局部完成問卷，做為對照。結果：以暴食問卷得分26以上為暴食症之定義，則暴食症總盛行率為1.8％，但是在不同的學校，盛行率有不同，高職女生高達3.3％，高職男生0％；高中女生0.9％。高中女生0.9％。高中男生0.5％。採用更嚴格的效標，盛行率可以低到1.1％。可能有暴食症的個案身體質量指數較重、月經較不規則，並且較常有激烈減肥的嘗試，簡式性格量表的神經質得分與家庭關懷度量表的得分均高於非個案，而趨近臨床個案的得分。結論：暴食症在臺北市的一所高中與一所高職學生的盛行率可能介於1.1％與1.8％之間，與西方國家相當。對於兩所被調查學校間盛行率的差異，值得更進一步研究。

　　　　　Objective: The aim of this study was to investigate the prevalence of bulimia nervosa in high schools in Taipei, Taiwan. Methods: 160 male and 1153 female students from an occupational high school, and 603 male and 584 female stuednts from a senior high school were investigated using the Chinese version of the Bulimic Investigatory Test, Edingburgh (BITE).Using concurrent applications of the Maudsley Personality Inventory (MPI) and the Family APGAR score, psychosocial aspects of the recruited subjects were measured. For comparison, the questionnaires were also administered to 27 patients attending group therapy for patients with bulimia nervosa. Results: Using the BITE score equal to or more than 26 as the criterion, the overall prevalence rate was 1.8%. The prevalence rates varied from group to group including, 3.3% for the female and 0% for the male students in the occupational school; 0.9% for the female and 0.5% for the male students in the senior high school. Using a stricter criterion, the total prevalence rate was as low as 1.1%. The subjects with bulimia defined using the BITE tended to be heavier, to have less regular periods, and to have tried more severe weight-reducing methods. The scores on the neuroticism subscale of the MPI and that of the family APGAR scores were higher in the bulimic students than in other students and resembled those of the clinical cases. Conclusion: The prevalence of bulimia nervosa in the two surveyed high schools was estimated to be between 1.1% to 1.8%, which is comparable to the results of students in Western countries. Further study to discern reasons for the different prevalence rates between the two schools is warranted.
