  2. *p < .05; **p < .01, ***p < .001.
  3. Reference category = 0; a0 = low and medium SES, 1 = high SES; b0 = boy, 1 = girl; c0 = no participation in extracurricular school-based sports in the current school year, 1 = participation in extracurricular school-based sports in the current school year; d0 = no participation in community sports in the current school year, 1 = participation in community sports in the current school year.
  4. Model 1b and 1c were both compared to model 1a to calculate χ2.
