Multinomial odds ratios shown are with reference to the low-alcohol frequency outcome category.

Percentages describing class distributions correspond to the sample of 5659 used for the unadjusted analysis.

Unadjusted model (n = 5659) –main effect of conduct problems trajectory on alcohol frequency pattern.

Adjusted model 1 (n = 5340) –adjusted for gender, housing tenure, over-crowding, parity and maternal education.

Adjusted model 2 (n = 4788) –additionally adjusted for pre-4y maternal alcohol use.
