Dietary Patterns and Age-Related Macular Degeneration in Korea: The Korea National Health and Nutrition Examination Survey 2010–2011

Abstract

This study was performed to reveal dietary patterns and age-related macular degeneration risk association in general Korean population. A retrospective cross-sectional database analysis using the data collected from January 2010 to December 2011 at a Korea nationwide survey was conducted. The present analysis was performed from December 2016 to November 2017. Detailed grading with fundus photographs was performed by observers blinded to the patient characteristics. The current study focused on subjects forty year and older who had fundus photographs that is assessable from at least one eye (7,899 participants). Participants were excluded if they reported extreme energy intake (142 participants) or if they were likely to have changed dietary behavior (1,171 participants), or with missing data (n = 764). After exclusion, 5,843 participants data were analyzed in the current study. As the result, 6.8% of the participants exhibited early stages of age-related macular degeneration and 0.6% exhibited late stages. Furthermore, relatively more frequent fish consumption was associated reduced odds of early age-related macular degeneration when comparing the third quartile with the first quartile groups, however, relatively more frequent legume consumption was associated with reduced odds of late age-related macular degeneration when comparing the third quartile with the first quartile groups. In conclusion, the current study insists that the diet pattern rich in fish and legume might have protective effect against age-related macular degeneration in Korean population.
