title: Consumption of caroltenoid-rich foods and central vision loss:a matched case-controlled study in Kansas.
abstract: The purpose of this study was to explore the association between consumption of carotenoid-rich foods and risk of central vision loss in 168 rural elders. Food consumption was estimated using a food frequency questionnaire. Median servings per week were used as the cut points for consumption levels. Odds ratios (OR) and 95% confidence intervals (CI) were calculated by using discordant pairs. High consumption of corn bread indicated significant association with central vision loss (OR 0.4; 95% CI 0.2, 0.9). Insignificant inverse associations were observed for seven other foods and the summary index of all selected foods. Prospective studies are needed to further evaluate the potential protective influence of carotenoid-rich foods on central vision loss among older adults.
