*Sample includes participants with social class at age 33 years (or at 23 years if data at 33 years missing; n = 12 229) and data on alcohol consumption at any one of the three time points.
†Non‐drinkers v drinkers, OR per unit change in occupational class at 33 years, grouped into four categories. Professional and managerial (RG I&II) categories are baseline.
‡Binge drinkers v other drinkers and non‐drinkers, OR per unit change in occupational class at 33 years, grouped into four categories. Professional and managerial (RG I&II) are baseline.
§The change in social gradient for drinking from age 23 to 42 years was tested using the interactions of social class with 33‐year time point and also social class with the 42‐year time point in a repeated‐measures model.
