AbstractThe association between dietary selenium intake and glaucoma remains unclear. Using data from the 2005 to 2008 National Health and Nutrition Examination Survey (NHANES), this study aimed to investigate the relationship between glaucoma and dietary selenium intake. The study included subjects aged 40 years or older who participated in the NHANES dietary intake interview and vision health questionnaire. Diagnosis of glaucoma based on self-reporting or fundus imaging. To investigate the relationship between daily selenium consumption and glaucoma, logistic regression analyses were employed. The potential linear relationship was found using smooth curve fitting. Subgroup analyses were also used. We found higher dietary selenium intake was associated with an increased risk of glaucoma (odds ratio, 1.39; 95% confidence intervals,1.07-1.81) on multivariable analysis. A linear association was found between dietary selenium intake and the occurrence of glaucoma in this population (Pnon-linearity = 0.951). Subgroup analyses showed a stable correlation between dietary selenium intake and the occurrence of glaucoma (all P for interaction > .05).This is the first study to look at the connection between dietary selenium intake and glaucoma based on the data from the 2005 to 2008 NHANES. Our findings suggested that dietary selenium intake maybe positively correlated with the risk of glaucoma in adults older than 40 years old. To find out the potential relationship between dietary selenium intake and glaucoma, More longitudinal studies are required.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
