“…The Korea National Health and Nutrition Examination Survey (KNHANES), the largest nation-wide health and nutritional surveillance system in Korea, suggested that vegetables and fruits are the most common sources of vitamin A and C [ 12 ]. Our earlier analyses confirmed that the sufficient total intake of vegetables and fruits reduced the risk of cataract, regardless of the type of consumption or cooking methods [ 13 ]. However, epidemiological evidences for the association between dietary intake of antioxidant nutrients vitamin A and C and the prevalence of cataract are still lacking in a Korean population.…”

Oxidative stress in eye lens is one of the main causes of the cataract. Dietary antioxidants including vitamin A and C are therefore known to be associated with the risk of the disease. However, evidences are still lacking in Koreans. This study aimed to examine whether dietary vitamin A and C levels are associated with the cataract, using data of Korea National Health and Nutrition Examination Survey 2012. A total of 3,344 individuals (599 cases and 2,745 controls) were analyzed in the study. Dietary data was classified into 3 groups following Dietary Reference Intakes for Koreans 2015: 1) ≤ estimated average requirements (EAR), 2) EAR-recommended nutrient intake (RNI), and 3) ≥ RNI. Findings suggested normal subjects (controls) had better vitamin A and C nutritional status. Vitamin A and C intakes of normal subjects were significantly higher than those of cataract cases (p < 0.001, respectively). Ratio of subjects who consumed vitamin A and C lower than EAR was higher in cataract cases compared to normal subjects (p < 0.001, respectively). These antioxidant intake levels predicted that having lower level of vitamins lower than EAR increased the odd ratios (ORs) for cataract [for vitamin A: OR, 1.89; 95% confidence interval (CI), 1.55–2.31 and for vitamin C: OR, 2.06; 95% CI, 1.69–2.51]. However, such associations were not retained, when the subjects’ demographic and lifestyle factor were adjusted. In conclusion, vitamin A and C showed a protective effect against cataract. However, subjects' life style and demographic factors nullified the association. More studies are required to verify the true association between dietary antioxidants and risk of cataract in Koreans.

“…Although these socioeconomic and life style factors were adjusted for in our analysis models, their effects might not have been controlled sufficiently. Our previous findings have shown that abundant intake of vegetables and fruits can reduce the risk of development of cataract [17]. Higher or more frequent intake of these foods are closely related with socio-economic status surrounding individuals [27,28].…”

“…Data of 3,285 subjects' sex, age, household income, practice of regular exercise, education, tobacco smoking, alcohol drinking, and the presence of diabetes mellitus were extracted from KNHANES 2012. Details for classification and analyses were described previously [17]. Dietary intake was obtained and adjusted with total energy intake prior to analysis using Willet's residual method [19].…”

“…Our recent study has shown that abundant intake of fruits and vegetables is protective against cataract in Korean males [17]. Furthermore, different types of fruits and vegetables (such as total vegetables, fruits, salted vegetables, and non-salted vegetables) possess differential modifying effect on the risk of cataract [17]. This suggests that, although antioxidants and phytochemicals that are rich in these foods could be major modifiers in reducing the risk of cataract, other nutritional intake such as sodium and potassium could be associated with the risk of cataract.…”

Purpose: Sodium intake is known to be a critical dietary factor in several diseases including cataract. Earlier studies have reported that excess intake of sodium may elevate the risk of cataract. However, little is known about this in Koreans. Thus, the purpose of this study was to examine whether dietary intake of sodium and potassium might modify the risk of cataract. Methods: A total of 1,319 males (219 cases) and 1,966 females (369 cases) from Korean National Health and Nutrition Examination Survey 2012 were analyzed. Energy adjusted dietary intakes of sodium and potassium and their ratios were evaluated to ascertain their associations with the risk of cataract. Dietary intake levels were stratified into quartiles and their risk modifying effects were estimated with logistic regression models with or without subjects' socio-economic characteristics and life styles for each sex. Results: Findings suggested that various descriptive factors were associated with the risk of cataract either in males or females. Males' intake levels of sodium and potassium and their ratios did not differ between phenotypes. Higher intakes or higher ratio was not associated with the risk of cataract. In contrast, female controls had higher intakes of sodium and potassium. Higher intake of potassium reduced the risk of cataract in females. However, such association was not retained when subjects' socioeconomic status and life styles were factored into the analysis. Conclusion: Dietary sodium and potassium intakes minimally affected the risk of cataract in Korean males and females. More studies are needed to ascertain the true pathological effect of sodium intake on cataract aetiology.
