This cross-sectional study of Korean women found that higher intakes of certain nutrients like fiber, omega-3 fatty acids, and vitamins A, C, and E were associated with a lower prevalence of dry eye syndrome, while higher intakes of carbohydrates, sugar, and fat were associated with a higher prevalence.
This cross-sectional study analyzed data from the Korea National Health and Nutrition Examination Survey (KNHANES 2019) involving 92,888 Korean women aged 40 and above to examine associations between dietary nutrient intake and the prevalence of dry eye syndrome. Using multivariate logistic regression, the researchers found a 7.7% prevalence of dry eye syndrome in the study population. Intakes of dietary fiber, protein, omega-3 fatty acids, water, calcium, phosphate, potassium, magnesium, and vitamins A, C, and E were inversely associated with the syndrome's prevalence. Conversely, higher intakes of carbohydrates, sugar, fat, cholesterol, sodium, iron, and zinc were associated with an increased risk. No significant associations were found for omega-6 fatty acids or vitamin D. The findings suggest that specific dietary patterns may influence dry eye syndrome risk in this population, but further research is needed to confirm these relationships.
