  1. Note. Adjusted for sex, age group, TV-viewing, urban/rural and ethnicity. OR odds ratio, CI confidence interval. Q, quintile. Both quintiles of income and educational level are based on the distribution of the sample into quintiles. As it was not possible to estimate the number of education years, the closest categorization of quintiles was: Q1- No education; Q2- Primary incomplete; Q3- Primary complete or incomplete high school; Q4- High school; Q5- More than high school
