大學生的健康信念、飲食相關自我效能與飲食行為研究

Health Beliefs, Diet-related Self-efficacy, and Diet Behavior of the College Students

本研究的主要目的係探討個人自覺罹患疾病的可能性和嚴重性與實行良好飲食行為可能得到的利益和障礙及實行的自信心與個人飲食行為的相關。母群體係某國立大學日間部八十二學年度註冊之全體學生共5241人，以分層系統抽樣方式抽取505位樣本從事問卷調查。結果發現：（一）、大學生飲食行為未臻理想：「吃宵夜」與「吃零食」的情形甚為普遍，「吃糙米飯、全麥食品」頻率較低，「喝含糖飲料」、「吃口味較鹹食物」、「添加調味料」及「吃油炸食品」等頻率較高。（二）、性別因素與攝取良好飲食行為有顯著相關。（三）、自覺可能罹患疾病和自覺實行良好飲食行為可得到的好處及可能阻礙以及實行良好飲食行為的自信心均與攝取飲食行為有顯著相關。研究者並對培養大學生飲食行為之教育介入及未來研究方向提出建議。
