This study analyzed the dietary conditions of Korean adolescents using the 2018 data from the Korea National Health and Nutrition Examination Survey (KNHANES), Korea Youth Risk Behavior Survey (KYRBS), and Consumer Behavior Survey for Food (CBSF). Totally, 397 (KNHANES), 60,040 (KYRBS), and 614 (CBSF) subjects were analyzed for this study. Subjects with normal weights were 69.0%, 73.0%, and 90.8%, respectively, and the rate of skipping breakfast was determined to be 31.8%, 33.6%, and 7.4%, respectively. The main reason for skipping meals was ‘not having enough time (78.3%)’, 45.2% of the subjects ate out more than ‘once/week’, 37.8% used the convenience store, and 51.9% ate out to eat delicious food. According to the KNHANES, the average food intake was 1,353.05 g/day, which differed in the amount of cereals, vegetables, seaweeds, oils and fat, and spices intake by gender. The nutrient intakes of energy, vitamin A, niacin, vitamin C, calcium, iron, dietary fiber and potassium were lesser than the recommended levels. Non-physical activity for more than 60 minutes a day per week was observed in 36.3∼82.0% of the subjects. Drinking experience among adolescents was 33.5∼42.3%, and the most popular frequency and amount of drinking were determined to be ‘once/month’ and ‘1∼2 glasses’, with almost no binge drinking reported. The experience of smoking was 14.9% for cigarettes, 7.9% for e-cigarettes, and 2.9% for heated tobacco, with 21.8% daily smokers, smoking an average of ‘2∼5 cigarettes/day (30.9%)’. Subjects receiving nutrition education were 21.2∼47.2%, with 95.8% having an awareness rate of nutrition labeling, but being implemented by a mere 33.2%.
