  1. Ref reference category SES socioeconomic status, TV television
  2. Model 1: Simple associations between each independent variable and weekend outdoor time, adjusting for covariates (age, sex and SES). Odds ratios for demographic variables (age, sex and SES) are therefore taken from a model in which all three were included simultaneously. Schools were treated as random effects in all models
  3. Model 2: Mutually adjusted model with all independent variables entered simultaneously, with schools treated as random effects
  4. Effects of continuous variables are assessed as one unit offsets from the mean
  5. *p < 0.05
  6. aA significant interaction for age*sex (p = 0.009) and for age*SES (p = 0.027) was found; see text for details
  7. P values taken from Type 3 Tests of Fixed Effects; italic font indicates significant result
