Socioeconomic inequalities in all-cause and cause-specific mortality among patients with osteoarthritis in the Skåne region, Sweden [link]Paper  doi  abstract   bibtex   
Objective To assess the association between education and all-cause and cause-specific mortality among patients with osteoarthritis (OA) in comparison to an OA-free reference cohort. Methods Using data from the Skåne healthcare register, we identified all residents aged ≥45 years in the region of Skåne, with doctor-diagnosed OA of peripheral joints between 1998 and 2013 (n=123,993). We created an age and sex-matched reference cohort without OA diagnosis (n=121,318). Subjects were followed until death, relocation outside Skåne, or the end of 2014. The relative index of inequality (RII) and the slope index of inequality (SII) were estimated by the Cox model and Aalen´s additive hazard model, respectively. Results We found an inverse association between education and mortality. The magnitude of relative inequalities in all-cause mortality were comparable in the OA (RII 1.53, 95% CI:1.46, 1.61) and reference cohorts (RII:1.54, 95% CI:1.47, 1.62). The absolute inequalities were smaller in the OA (SII 937 all-cause deaths per 100,000 person-years, 95% CI:811, 1063) compared with the reference cohort (SII 1265, 95% CI:1109, 1421). Cardiovascular mortality contributed more to the absolute inequalities in the OA than in the reference cohort (60.1% vs. 48.1%) while the opposite was observed for cancer mortality (8.5% vs. 22.3%). Conclusion We found higher all-cause and cause-specific mortality in OA patients with lower education. The observed inequalities in the OA cohort reflect the inequalities in the population at large. The greater burden of cardiovascular diseases in OA patients suggests that proper management of cardiovascular risk factors in OA patients is important.
