Background: Frequent fast food consumption by adolescents is a leading cause of obesity. The present study focuses on finding the predictors of fast food consumption of Korean middle- and high-school students. Finding the predictors will ultimately provide evidence based strategies needed to effectively lower obesity prevalence, along with focusing on intervention for breakfast skippers.
Methods: Multiple regression model was applied using data from the National Youth Policy Institute. We used the national representative survey data obtained via multistage stratified area probability sampling design from 2,943 middle- and high-school students consisting of 1,570 males and 1,373 females.
Results: From the entire sample, 16.4% was shown to consume fast food more than once a week, and 54.3% was shown to skip breakfast more than once a week. Multiple regression analysis, after adjusting for control variables, revealed that frequent breakfast skippers used fast food restaurants more frequently (P < .001).
Conclusion: Preventing adolescents from skipping breakfast may reduce their fast food consumption and lead to prevention of obesity.
