The purpose of study was to examine the factors influencing fast food consumption in Korean adolescents. The analysis was conducted using cross sectional study data from the 16th Korea Youth Risk Behavior Web-based Survey in 2020. A total 54,948 middle and high school students participated in this study. The subjects in the analysis were 28,353 males and 26,595 females, 28,961 middle school and 25,987 high school students. In total, 56.6% Korean adolescents consumed fast food once or twice weekly and 25.4% consumed fast food more than three times weekly. Logistic regression analysis revealed that fast food consumption was significantly associated with dietary behavior such as lower breakfast intake (OR: 0.930, 95%CI: 0.891~0.970, p<0.001), higher soda drinks consumption (OR: 2.563, 95%CI: 2.452~2.678, p<0.001), and higher sweet drinks consumption (OR: 1.898, 95%CI: 1.818~1.982, p<0.001). For psychological and health behavior factors, fast food consumption was also significantly associated with higher perceived stress (OR: 1.239, 95%CI: 1.163-1.321, p<0.001), higher smoking (OR: 1.300, 95%CI: 1.164~1.453, p<0.001), higher drinking (OR: 1.193, 95%CI: 1.112~1.280, p<0.001), higher depression experience, higher loneliness experience, and lower subjective health, In conclusion, fast food consumption in Korean adolescents was associated with undesirable dietary habits and psychological and health behavior, suggesting that appropriate education programs are necessary to reduce such behavior.

There were significant differences in the influence factor for the selection of fast food according to taste seeking and, popularity seeking types (p<0.05). Also, the easy seeking and safety seeking lifestyle types showed a significant differences for the reason the choosing criteria of fast food (p<0.05). Especially, the nutrition problem was of the highest importance for the health and safety seeking but an advertisement effect trend appealed more to the taste seeking, easy seeking and popularity seeking lifestyles.

A significant positive result of the internal characteristics of fast food consumption (p<0.05) was shown for the health seeking and safety seeking types. A significant positive result of the external characteristics of fast food consumption (p<0.05) was shown for the popularity seeking and safety seeking types.

This study was designed to provide fundamental data on the consumption of fast food for a balanced diet of university students. The effects of personal characteristics and preferences such as gender, major, residing region, living expense, school grade, dieting, physical activity, smoking and alcohol consumption on fast food consumption patterns were analyzed by surveying university students. The analysis showed significant differences (p<0.05) in the consumption of different types of fast food depending on different personal characteristics and preferences as follows : hamburger by major, physical activity and alcohol consumption; chicken by school grade, physical activity and alcohol consumption; spaghetti by gender and smoking. Groups of different majors and school grades showed significant differences (p<0.05) in response to a question “Have you ever eaten fast food for regular meals?”. The choice of fast food types based on taste and price appeared to be significantly influenced by majors and gender. Different groups with different majors and dieting experience appeared to think significantly differently about fast food. In response to a question “Has the consumption of fast food changed your diet style” different groups of different majors and physical activities showed significant differences. The analysis of factors affecting fast food choices revealed that fast food is chosen significantly differently depending on gender and majors (p<0.05). The purchase of fast food appeared to be significantly affected by gender, diet, physical activity, experience of fast food and consumption of fast food for regular meals (p<0.05).

부산지역 대학생 340명을 대상으로 패스트푸드점 이용실태를 조사한 결과 다음과 같다. 1. 조사 대상자는 남학생 56.2%, 여학생이 43.8%이었고, 20-24세가 66.8%를 차지하였고, 자기집에 거주하는 학생이 73.6%이었으며. 평균용돈은 16-20만원이 31.8%로 가장 많은 비율을 차지하였다. 2. 대상자 중 패스트푸드점을 이용하는 대학생이 83.3%로 남학생이 77.6%, 여학생이 90.3%, 19세이하가 88.1%를 차지하였으며, 자기집에 거주하는 학생이 87.7%, 월평균용돈의 액수에 상관없이 높은 비율의 학생이 이용하고 있었다. 3. 패스트푸드점을 이용하는 시간대는 아무 때나가 44.7%로 가장 많았으며, 저녁시간, 점심시간 순으로 남학생은 아무 때나, 저녁시간대가 많았고, 여학생은 모든 시간대에 비슷한 비율로 높았다. 또한 자기집에 거주하는 학생이 아무 때나, 저녁시간대 이용하는 비율이 높았다. 4. 1회 이용시 평균비용은 삼천원대가 가장 많았는데 남학생은 삼천원이상 비용대의 비율이 높았고 여학생은 삼천원 비용대에서 두드러지게 그 비율이 높았다. 또 연령이 높을수록 비용이 많이 들었고, 자취와 하숙생이 삼천원 이상의 비용을 이용하는 비율이 높았으며, 평균용돈이 많을수록 삼천원 이상의 비용대의 비율이 상대적으로 높았다. 5. 패스트푸드점 이용시 메뉴선택은 기호에 따라 선택하는 비율이 64.5%로 가장 높았고, 남학생에 비해 여학생이 기호에 따라 선택한다는 비율이 80.1%로 높았다. 6. 대학생들이 이용하는 패스트푸드점은 맥도널드이었으며 특히 남학생보다 여학생이 상대적으로 월등히 높게 나타났다. 연령이 낮을수록 맥도널드, 롯데리아 등을 많이 이용하였고, 나이가 많을수록 다른 패스트푸드점도 이용하는 것으로 나타났다. 이와같은 결과로 볼때 대학생들의 패스트푸드점 이용은 점점 증가하고 있고, 소비하는 비용도 많아져 가고 있어 젊은이들의 식습관에 문제가 되리라 사료된다. 그러므로 패스트푸드의 영양성을 고려한 메뉴개발 등의 노력이 필요하며 미래의 주역이 될 대학생들의 식습관에 대한 보다 심도있는 연구가 함께 병행되어야 할 것으로 생각된다.
