夜間進修是現代人獲取知識的重要途徑之ㄧ，但匆促的生活對飲食習慣影響則不得而知。因此，本研究目的即在於探究夜間進修學生之飲食習慣。研究對象為中部某一科技大學夜間進修學生，18-40歲獨立樣本323人，男性46人，女性277人。以結構型限制式問卷進行調查，問卷內容包括個人的基本資料、飲食習慣及食物攝取頻率等項目。結果顯示，因夜間進修使半數學生不吃早餐，1/3晚餐進食量會減少，2/3會吃宵夜，三餐皆外購外食者超過50%；西式速食品以選擇油炸食品居多；保健食品以選擇維生素、礦物質補充劑者居多 (42%)，但只有9.7％持續服用。每天飲用奶類只有20%；每天選食蔬菜、柑橘類水果者為43%與16.8%；每天選食主食類1-2次者76.9%；每天會選食優質蛋白質1-2次為70.5%；食物烹調方式以煎、炒、炸居多。因此，夜間進修學生因用餐時間倉促，選擇食物多未考慮到營養均衡問題，故提升夜間進修學生均衡飲食習慣與培養正確的食物選擇知識，將是下一個階段的重要課題。

Evening school is a convenient way for extensive and advance education for people with a full time job at daytime. Life might turn into a rush after going to evening school and also distort diet habit and quality. The purpose of this study is to explore the eating habits and dieting quality among evening school students. Subjects were recruited from an evening school of a university in central Taiwan and aged between 18-40 years old. Over all 323 subjects which included 46 males and 277 females completed a structured questionnaire. The questionnaire included personal data, eating habits and food intake frequency. The results showed that half of the subjects do not eat breakfast, one third reduced food intake for supper, and two thirds eat late night snack. More than 50% of subjects eat out; most subjects often choose fried food; 42% of subjects take vitamins and mineral supplements, but only 9.7% of subjects use continually. Only 20% of subjects drink milk daily, 43% of subjects eat fresh vegetables, and 17.5% of subjects take fruits daily. 76.9% of subjects eat staple food 1 or 2 times daily; 70.5% of subjects have high quality protein 1 or 2 times per day. Most cooking methods are fried, stir-fried or deep-fried. The results show that most evening school students have poor diet habit and nutrition quality, improvement is thus required.
