北部某醫學中心員工之營養知識、營養態度與飲食行為相關因素研究

本研究為探討醫學中心員工之營養知識、營養態度與飲食行為現況，及個人背景因素對營養知識、營養態度與飲食行為之差異，並了解營養知識、營養態度與飲食行為三者相關性。以北部某醫學中心員工為本研究的母群體，並採用分層集束抽樣法進行抽樣，以自編式問卷調查法進行資料收集，共取得359份有效問卷。研究資料採用描敘性統計、獨立樣本T檢定、單因子變異數分析、皮爾遜積差相關及複迴歸分析等統計方法進行分析，研究結果如下：一、研究對象營養知識在食物之營養素答對率較高，而均衡飲食知識答對率則較低；營養態度在均衡營養部分較佳，而情緒性進食態度則較差；飲食行為在食物攝取頻率及份量較佳，而均衡飲食與進食技巧則較差。二、個人背景因素以年齡、教育程度與職稱等變項對於營養態度與飲食行為具有顯著性差異。三、關於營養知識、營養態度與飲食行為三者相關性，營養知識與飲食行為無顯著相關，營養知識與營養態度為正相關（p< 0.001），營養態度與飲食行為顯示正相關（p< 0.001）。四、個人背景變項與營養知識對飲食行為無法預測，而營養態度可有效預測飲食行為，並可達19.6%的預測力。最後根據上述研究結果，提出建議供未來相關研究的參考。
