^aCategorization based on the Cole and Lobstein Classification⁴⁵.

^bCompared to Normal weight.

^cMain effects from multinomial logistic regression. Variables in the model: age, sex, language, sleep duration on school nights, weekly exercise, TV viewing and computer use.

^dCategorization based on the distribution of responses for two questions on recreational TV viewing during school days and weekends/days off.

^eCategorization based on the distribution of responses for two questions on recreational computer use during school days and weekends/days off.

OR, odds ratio; CI, confidence interval.
