神經性厭食症研究在西方國家有較高的盛行率，且隨著世代的演進而有與日俱增的趨勢。本研究目的為探討神經性厭食症患者住院資料及流行病學特性。使用全民健保資料庫，取2002~2007 年曾住院的神經性厭食患者為研究對象共171位，探討台灣地區住院之神經性厭食症患者其醫療利用情形及流行病學分析。研究結果顯示，研究對象女性多於男性，男女比約1：4.5，平均年齡為26.33 歲，年齡分層以15~24 歲最多，高共伴疾病，多於醫學中心住院，皆為自願住院，平均住院天數為20.42 天，每次住院平均醫療費用為54,764.44 元，平均住院次數為1.16 次，住院科別以精神科最多，其次為內科及小兒科。在了解神經性厭食症其醫療利用情形後，對此疾病族群的疾病症狀，可早期被辨識出及早期介入治療，以減緩其病程進入慢性化及增加治癒率。

This study explored health resource use in anorexia nervosa (AN) patients in Taiwan. By using the Psychiatric Inpatients Medical Claims Data of the 2002-2007 National Health Insurance Research Database, Registry for Contracted Medical Facilities and Registry for Beneficiaries, a total of 171 hospitalized patients with AN were analyzed in this study. AN occurs in women more often than in men, particularly in women between the ages of 15 and 24. For the patients with An in this study, the average duration of hospitalization was 20.42 days, and the average medical expense associated with each hospitalization was 54,764.44. The average number of hospital visits for patients with An in this study was 1.16, and these patients were mainly hospitalized in the psychiatry division, followed by the internal medicine and pediatrics divisions. Age, number of comorbidities, low-income family status, catastrophic illness card possession, and the contracted category signifi cantly affected the use of hospitalization among patients with An in Taiwan.
