Most studies of older persons only include measures of current socioeconomic status (SES) and do not take into account data from earlier stages of life. In addition, only classic SES measures are used, while alternative measures, such as car ownership and house ownership, might equally well predict health. The present study aims to examine the effect of midlife socioeconomic factors on mobility limitation and depressed mood three decades later. Methods: Data were from 4,809 men and women aged 33–65 years who participated in the Reykjavik Study (1967– 1992) and who were re-examined in old age in the Age, Gene/Environment Susceptibility (AGES) -Reykjavik Study (2002–2006). Results: Education and occupation predicted mobility limitation and depressed mood. Independently, home and car ownership and the availability
