... ticipants whose age range ran from 90 to 107 years. Education and former main occupation were used as indicators of socioeconomic status, and health was measured as functional ability, comorbidity, and self-rated health. Data were analyzed in a cross-sectional design using cross tabulation, ordered regression model with marginal effects, and binary logistic regression model. Results. Manual workers had poorer functional ability and health than upper nonmanuals and similarly the loweducated suffered more from health issues than the high-educated. Most analyses showed a graded association between the lower socioeconomic status and a poorer health outcome. On each level of the socioeconomic hierarchy, men had better functional status than women. Discussion. We found socioeconomic differences in functional ability, comorbidity, and self-rated health in nonagenarians. Our findings suggest that social disparity in health and functioning exists in very old age.
