Logistic regression analyses for associations between home environment characteristics and using computers or game consoles by the child (n = 3067.

For details on the measures used, see Appendix S1.The frequencies (n (%)) and means presented are frequencies and means of the original dataset. Missing values were 116 (3.8%) for family rules about using computers or game consoles, 145 (4.7%) for parental monitoring, 146 (4.8%) for parental urging to turn off the computer or game console, 158 (5.2%) for child autonomy concerning using computers or game consoles, 19 (0.6%) for number of computers or game consoles in the household, and 10 (0.3%) for whether the child has a computer or game console in the bedroom.The ORs are the pooled results of analysis of the five imputed datasets.The ORs are adjusted for sociodemographic characteristics (sex and age of the child, ethnic background of the child, educational level of the parent, employment status and family structure).aThe reference category (OR = 1.00) is ‘no rules’.bThe reference category (OR = 1.00) is ‘never, seldom, or sometimes’.cAn increase on child autonomy indicates higher autonomy of the child concerning screen time.dHouseholds without a computer or game console (n = 390, 2.7%) were excluded from analysis.eThe reference category (OR = 1.00) is ‘no’.
