Multiple logistic regression analysis employed to calculate odds ratios (ORs) for adjust possible confounders. total 2054 individuals participated checkups. In 1156 (response rate: 56.28%) analyzed study, mean (SD) age 63.0 (8.7) years, percentage women higher (57.87%), 26.38% (95% CI 23.86%–29.03%). Multivariate revealed that were older (adjusted OR: 1.054 [95% CI: 1.034–1.075]), female sex 1.388 1.006–1.915]), distance-presenting vision impairment 2.651 1.697–4.143]).
