Marital status and 5-year mortality: A population-based prospective cohort study
1Social Medicine and Health Policy, Department of Clinical Sciences in Malmö, Lund University, S-205 02 Malmö, Sweden.
Objectives:
The aim was to investigate the association between baseline marital status and mortality using survival (Cox-regression) analysis.
Study Design:
This is a prospective cohort study.
Methods:
The public health survey by Scania in 2008 was linked to the Swedish cause of death register. This prospective cohort study includes 12,245 men and 14,969 women aged 18-80 years, and 538 men and 362 women of them died during the 5.3-year follow-up.
Results:
Unmarried, divorced, and widowed men had significantly higher hazard rate ratios (HRRs) of all-cause mortality than married/cohabitating men. For women, the HRRs of these groups did not significantly differ from those of the married/cohabitating reference group.
Conclusions:
The results are in accordance with a previous study that only compared those living alone with those cohabitating.
