Long-term care (LTC) use increases with ageing due to an age-related increase in disability. Both the levels of disability and social resources vary among socioeconomic groups. The association of socioeconomic status with LTC use is largely unexplored for the oldest old. This study examined how occupational class is associated with LTC use among nonagenarians in the context of universal care coverage. A population-based prospective cohort study with 2862 participants who answered the Vitality 90 + Study surveys in 2001, 2003, 2007, or 2010 in Tampere, Finland, was combined with national register data on LTC use. LTC use in total and separately for publicly and privately provided LTC facilities was assessed in a cross-sectional setting and during the 34-month follow-up by using logistic regression and competing-risks regression methods. Functional status, multimorbidity, family relations, and help at home were controlled. In total or public LTC use, only a few differences between occupational classes were found at baseline. However, upper non-manuals used more private LTC than lower non-manuals (OR 0.54, 95% CI 0.35-0.85), skilled manuals (OR 0.40, 95% CI 0.26-0.62), or housewives (OR 0.40, 95% CI 0.22-0.74). There were no statistically significant differences in entering any kind of LTC after adjustments for all independent variables. During the study period, the share of privately provided care out of all LTC increased and the upper non-manuals no more used private care more than other groups. This study underlines the importance of following the structural changes in LTC provision to guarantee that the need for LTC is met equally for all socioeconomic groups.
