| 摘要: | 本研究旨在分析個人屬性對健康飲食認知之影響，瞭解成人不健康食物攝取行為之現況，並進一步探討健康飲食認知對不健康食物攝取行為之影響與相關性、不健康食物攝取行為與自覺健康狀況之相關性。以大臺北地區20歲至65歲以下成人為研究對象，採取問卷調查法，並以網際網路作為發放之平台，依性別與年齡比例分層抽樣，總共回覆555份，有效問卷542份，有效問卷回覆率為97.7%。以描述性統計、獨立樣本ｔ檢定、單因子變異數、卡方及皮爾遜積差相關進行統計分析。其研究結果為：
一、健康飲食認知各構面會因性別、年齡、職業、婚姻狀況、是否參與食品營養課程講座、早餐外食（外帶）頻率之不同均有顯著差異；而部分構面會因居住地、體型、腰圍、教育程度、運動頻率、午餐外食（外帶）頻率、晚餐外食（外帶）頻率之不同會有顯著差異。
二、不健康食物攝取行為之攝取頻率、購買考量兩構面會因個人屬性之不同而部分有顯著差異；不健康食物購買狀況與個人屬性部分有顯著關聯。
三、健康飲食認知與不健康食物攝取行為之攝取頻率構面有顯著相關；健康飲食認知與不健康食物攝取行為之購買考量構面有部分顯著相關。
The study aimed to analyze the influence of personal attributes on healthy diet cognition, to understand contemporary adults’ unhealthy diet taking status, and to discuss the impact of healthy dietary cognition on unhealthy diets taking behavior. Additionally, the correlations between healthy dietary cognition,
unhealthy dietary taking behaviors, and self-conscious health conditions were also evaluated. Participants were adults in Taipei area, ranging from twenty to sixty-five years old. Computerized questionnaires were collected from internet, which were sampled proportionly according to genders and ages in Taipei and New Taipei cities. Totally, 555 questionnaires were replied. Among them, 542 responses were valid. The valid response rate was 97.7%. Data were analyzed using the following statistical analyses: descriptive statistics,independent-samples t-test, one-way ANOVA, chi-square, and pearson product-moment correlation coefficient. Results showed that:
1.All constructs of healthy diet cognition were significantly different between/among gender, age, occupation, marital status, whether to participate in food and nutrition seminar, and frequency of dining out for breakfast; while some constructs were significantly different among place of residence, body built,waist circumference, educational background, exercise frequency, and dining out frequencies for lunch and dinner.
2.The frequency of purchasing unhealthy foods and purchase consideration were significantly different among participants’ personal attributes. Purchase condition of unhealthy foods was significantly associated with participants’ personal attributes.
