Abstract
OBJECTIVES
Studies have suggested that the dietary intake of antioxidant vitamins, such as vitamin C and vitamin E, has a potential role in inhibiting gastric carcinogenesis. The present study investigated the effect of antioxidant vitamins on the incidence of gastric intestinal metaplasia (GIM).
METHODS
This study included 67,657 Koreans free of GIM who periodically underwent health check-ups. Dietary intake was assessed by a semiquantitative food frequency questionnaire based on the Korean National Health and Nutrition Examination Survey. Participants were categorized into 4 groups by quartiles of dietary vitamin C and vitamin E intake. The Cox proportional hazard assumption was used to determine the multivariable hazard ratio (HR) and 95% confidence interval (95% CI) for GIM.
RESULTS
The third and fourth quartiles of vitamin C intake had a lower risk of GIM than the first quartile (multivariable-adjusted HR, 0.95; 95% CI, 0.88 to 1.03 in the second quartile, HR, 0.88; 95% CI, 0.81 to 0.97 in the third quartile, and HR, 0.85; 95% CI, 0.76 to 0.95 in the fourth quartile). Vitamin E intake greater than the second quartile level was significantly associated with a lower risk of GIM than the first quartile (multivariable-adjusted HR, 0.90; 95% CI, 0.82 to 0.97 in the second quartile, HR, 0.90; 95% CI, 0.82 to 0.99 in the third quartile, and HR, 0.83; 95% CI, 0.74 to 0.94 in the fourth quartile). This association was observed only in the subgroup analysis for men.
CONCLUSIONS
Higher dietary intake of vitamin C and vitamin E was associated with a lower risk of GIM.
Summary
Korean summary
본 연구에서는 6만명 이상의 한국인을 대상으로 비타민 C와 비타민 E의 섭취량과 장기적인 위 장상피화생 (GIM) 발생 위험도의 상관 관계를 연구했다. 우리는 비타민 C와 E 섭취량이 많은 근로 연령대의 한국인에서 낮은 위 장상피화생 발생 위험을 확인했다. 이 연관성은 여성보다 남성에서 더 분명하게 나타났다.
Key Message
1. This study investigated the long-term effect of vitamin C and vitamin E intake on the longitudinal risk of GIM in more than 60,000 Koreans 2. We found increased intake of Vitamin C/E is associated with lower incidental risk of GIM in working aged Korean. 3. This association was more prominent in men than women.
