Analyses are stratified for year of birth and adjusted for age and year at testing.
Model 1: adjusted for year and age at testing.
Model 2: adjusted as for model 1 plus childhood socioeconomic status and height and body mass index at start of military service.
Model 3: adjusted as for model 2 plus adult education.
