本研究以台中縣市的高中女生為研究對象，除了探討其罹患病態飲食的相關危險因子外，包括體位認知、體型滿意度及各種減重經驗，更進一步以EAT-26問卷篩選出具病態飲食傾向的高危險群，深入了解其血液生化值及營養攝取狀。以不記名自填式問卷為研究工具，共分為三個部分：（A）基本資料、用餐情形及體重關注（B）EAT-26（C）24小時飲食回憶。結果發現有81.6﹪的受試者希望自己再瘦一點,全體受試者中有43.8﹪的人有減重經驗，而有19.5﹪人目前正在減重。有17.11﹪的受試者EAT-26積分大於可界定為高危險群傾向的標準（EAT≧20）。EAT（＋）的受試者其熱量、蛋白質、醣類、維生素B6及鋅的攝取明顯低於EAT（－），但在粗纖維及膳食纖維的攝取顯著較高。（5）EAT（＋）的受試者其TIBC及serumiron的值屬於不正常的人數比例明顯高於EAT（－）。本研究發現EAT-26篩選出具病態飲食傾向的高危險群，除了有異常的飲食行為外，更可預測其實際營養攝取狀況可能較一般人差，甚至有影響到血液生化值的危險。
The purpose of this study is to investigate the eating disorder related thoughts, behaviors and their relationship with food intakes and nutritional status in high school students. Written questionnaire including of demographics and weight concern, EAT-26 and 24hrs dietary recall were distributed for data collection. Result indicated that among of all subjects, there were 81.6% desired to be thinner, 43.8﹪had experiences of intentionally weight loss and 19.5﹪ currently try to weight loss. More than 17% of subjects had EAT-26 score above the cutoff point(≧20). The EAT(+)subjects had significantly less energy , protein, carbohydrate, vitamin B6 and Zinc intake than EAT(-)s, on the contrary, they had higher intakes of fibers. EAT(+)s had higher percentage of subjects with the abnormal values of TIBC and serum iron than EAT(-)s. This study suggests that EAT-26 may also used to predict subjects’ nutrition intake and nutrition status. This needs further investigation.
