Model 1- Adjusted odd ratios- Controls for sociodemographic characteristics- (Gender, Ethnicity, FAS- Family Affluent Scale, Family-Structure).
Model 2- Adjusted odd ratios- Controls for (sociodemographic characteristics) drink and smoke.
Model 3- Adjusted odd ratios- Controls for (sociodemographic characteristics, drink, smoke) health and previous wave.
Weighted for sampled school clusters, participant weight, Strata.
- Empty cells- no same measure in previous year.
p < 0.05,
p < 0.01,
p < 0.001- for indicate P values for differences between AOR of frequent group to occasional group.
Multinomial logistic regressions for each measure independently both for occasional vs. non-use, and frequent vs. non-use in the same model.
