^aModel 1 also adjusted for immigrant status. Model 2 also adjusted for time-varying measures of current retirement status, current marital status, and current total household wealth. Model 3 also adjusted for time-varying measures of current smoking, current drinking, current self-rated health, and current number of health conditions, as well as unit nonresponse and mortality. All covariates, except for immigrant status, mortality, and unit nonresponse, were centered at their grand means. All covariates were interacted with age.

^b≥ 12 years and < 12 years refers to years of schooling completed.

^cReference group: 1931–1936 cohort.

^dAge is modeled as [(age − 62) / 10] for main effects and interactions.
