After multiple adjustments, self-reported cataract surgery predicted 36 percent elevated risk for vascular-related mortality
THURSDAY, Oct. 28, 2021 (HealthDay News) — Self-reported cataract surgery is associated with all-cause mortality and vascular-related mortality, according to a study published online Oct. 25 in the British Journal of Ophthalmology.
Yifan Chen, M.D., Ph.D., from the Guangdong Provincial People’s Hospital in Guangzhou, China, and colleagues used data from the 1999 to 2008 cycles of the National Health and Nutrition Examination Survey to examine the association between self-reported cataract surgery and all-cause and cause-specific mortality. Mortality data were obtained from National Death Index records.
Data were included for 14,918 participants. The researchers found that 3,966 participants (19.1 percent) died during a median follow-up of 10.8 years. Compared with those without, participants with self-reported cataract surgery had an elevated likelihood of dying from all causes and specific causes (vascular disease, cancer, accident, Alzheimer disease, respiratory disease, renal disease, and others). After multiple adjustments, the association between self-reported cataract surgery and all-cause mortality remained significant (hazard ratio, 1.13). Self-reported cataract surgery predicted an elevated risk for vascular-related mortality in multivariable models (hazard ratio, 1.36); for other specific causes of mortality, the association did not reach statistical significance after multiple adjustments.
“More studies are needed to confirm these associations and to further investigate the mechanisms behind these associations,” the authors write.
