INTRODUCTION: Socioeconomic position and working situation are two factors associated to health inequalities and to each other. AIM: To study how socioeconomic position and working conditions 20+ years earlier associates to physical functioning after retirement age. DATA: Swedish nationally representative samples, from 1968, 1981, and 1991 were re-interviewed 1992, 2002, and 2011 (76+) with 20-24 years follow-up time (women, n=431; men, n=450). METHOD: Ordered logistic regressions, censored normal regression, and ordinary OLS regressions will be used. VARIABLES: Physical function: Self-reported mobility, objective tests of lung function and general physical function. Socioeconomic position: Education, income, cash margin, social class based on occupation, and an index based on all measures. Psychosocial working conditions: job control, psychological demands, high strain (low control+high demands) and work complexity regarding data (information), people, and substantive (general) complexity. Controls: age, sex, follow-up year, mobility at baseline, and hours worked. RESULTS Job control, work complexity with data and people and all measures of SEP, were significantly associated to the three measures of physical function. Controlling for working conditions, the only significant associations was between general physical function and cash margin and the socioeconomic index respectively. When controlling for socioeconomic position, job control was significantly associated to less limitations in mobility and general physical functioning, substantive complexity and complexity with data were associated to less mobility limitations. CONCLUSIONS Both socioeconomic position, work related stress, and work complexity were associated to physical function in old age, but only partly independent of each other. The strongest single factor is job control.
