Sleep apnea, disability pension and cause-specific mortality: a nationwide register linkage study
Research output: Contribution to journal › Journal article › Research › peer-review
Sleep apnea is a common problem affecting daily functioning and health. We evaluated associations between sleep apnea and receipt of a disability pension and mortality in a prospective study of 74,543 cases of sleep apnea (60,125 outpatient, 14,418 inpatient) from the Swedish Patient Register (2000–2009 inclusive). Cases were matched to 5 noncases (n = 371,592) and followed from diagnosis/inclusion to December 31, 2010, via nationwide registers. During a mean follow-up period of 5.1 (standard deviation, 2.7) years, 13% of men and 21% of women with inpatient sleep apnea received a disability pension. Inpatient sleep apnea was associated with higher total mortality (for men, hazard ratio (HR) = 1.71, 95% confidence interval (CI): 1.59, 1.84; for women, HR = 2.33, 95% CI: 2.04, 2.67), with associations being strongest for deaths due to ischemic heart disease (for men, HR = 2.27, 95% CI: 1.94, 2.65; for women, HR = 5.27, 95% CI: 3.78, 7.34), respiratory disorders (for men, HR = 3.29, 95% CI: 2.45, 4.42; for women, HR= 5.24, 95% CI: 3.52, 7.81), and suicide (for men, HR = 1.76, 95% CI: 1.19, 2.60; for women, HR = 4.33, 95% CI: 1.96, 9.56). There were no associations of inpatient sleep apnea with cancer mortality. Outpatient sleep apnea was associated with a higher risk of receiving a disability pension but not higher total mortality. In conclusion, inpatient sleep apnea is related to a higher risk of disability pension receipt and mortality a decade after diagnosis.
