OR: odds ratio, CI: confidence interval. To reflect the stratified cluster sampling design of the 2007 Korea Youth Risk Behavior Web-based Survey, ORs and 95% CIs were constructed using the “survey logistic procedure” of SAS version 9.1.

^aIncluding the following variables: grade level of student, vigorous physical activity, moderate physical activity, sedentariness, fruit consumption, milk consumption, fast-food consumption, soft drink consumption, routine consumption of breakfast, weight control behavior, inadequate weight control behavior, smoking, perceived stress and depressed mood, paternal and maternal education.

^bIncluding the variables in model 1 plus family affluence scale instead of parental education.

^cIncluding the variables in model 1 plus subjective family economic status and subjective school achievement instead of parental education.

^dIncluding the variables in model 1 plus family affluence scale, subjective family economic status, and subjective school achievement.
