Note. Cognitive impairment classifies those with 10 % lowest scores on the sum score of cognitive function as relatively cognitively impaired. OR, odds ratio; CI, confidence interval.
Models stratified by ISCO information on last job (professional and managers, intermediate or lower supervisors, clerks, lower sales and services, lower technical and routine workers). Model 1 covariates: country indicators, age, gender; Model 2 additional covariates: reported number of books in the household at age 10 in quintiles, availability of less than two items of household equipment at age 10 (fixed bath, cold running water supply, hot running water supply, inside toilet, central heating), ISCO information of main breadwinner’s occupation at age 10 in five categories (professional and managers, intermediate or lower supervisors, clerks, lower sales and services, lower technical and routine workers, and missing information), self-rated mathematical skills and language skills at age 10 relative to others, ISCED information on educational attainment in four categories (up to lower secondary, upper secondary, tertiary education, and missing information).
Model 3 additional covariates: household income, household wealth, self-rated health, one or more limitation on any of Instrumental Activities of Daily Living (IADL), indicator variables indicating having been diagnosed with a medical condition (heart attack, high blood pressure or hypertension, high blood cholesterol, stroke, and diabetes or high blood sugar).
