Abstract [en]

Background: The association of living alone with hospitalization among the general elderly population has been rarely investigated, and the influence of common disorders on this association remains unknown. Methods: We used data on participants in the Swedish National study on Aging and Care in Kungsholmen (n = 3130). Risk and number of unplanned hospitalizations and length of hospital stays were studied over a period of 2 years. We used Cox proportional hazard models to estimate hazard ratios (HRs) of incident hospitalization and zero-inflated negative binomial regression models adjusted for potential confounders to estimate incident rate ratios (IRR) of the number of hospitalizations and total length of stay associated with living alone. Results: A total of 1768 participants (56.5%) lived alone. Five hundred and sixty-one (31.7%) of those who lived alone had at least one unplanned hospitalization. In the multivariate analyses, living alone was significantly associated with the risk of unplanned hospitalization (HR = 1.21, 95% confidence interval [CI] 1.01-1.45) and the number of hospitalizations (IRR = 1.35, 95% CI 1.04-1.76) but not with the length of hospital stays. In stratified analyses, the association between living alone and unplanned hospitalizations remained statistically significant only among men (HR = 1.52, 95% CI 1.17-1.99). Conclusions: Living alone is associated with higher risks of unplanned hospitalization in elderly, especially for men.
