Results of crude and adjusted multilevel logistic regression analyses.

Analyses were restricted to students who had complete data on all model variables.

^*p<0.05,

^**p<0.01,

^***p<0.001.

^†ORs adjusted for age, gender, family affluence, school performance, television screen time, number of movies seen, sensation seeking and rebelliousness and smoking within the social environment (peers, parents and siblings).
