| *Sample includes participants with qualifications at age 33 years (n = 11141) and data on alcohol at any one of the three time points. Sample is largest at age 33 years, when data on qualifications were recorded. | |||||
| †Non-drinkers v drinkers, OR per unit change in qualifications at 33 years, grouped into five categories. Higher qualifications (>A level) are baseline. | |||||
| ‡Binge drinkers v other drinkers and non-drinkers, OR per unit change in qualifications at 33 years, grouped into five categories. Higher qualifications (>A level) is baseline. | |||||
| §The change in educational gradient for binge drinking from 23 to 42 years was tested using the interactions of qualifications with the 33-year time point and also qualifications with the 42-year time point in a repeated-measures model. | |||||
