The aim of the present study was to evaluate the associations between dietary patterns and blood levels of lead and mercury in Korean adults. A total of 858 Korean adults (≥20 years) who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) V-1 2010 were included in this study. Data of biochemical measurements including blood lead and mercury levels, nutrients intakes and anthropometric measurements were acquired. 'Balanced diet', 'Grain and kimchi', and 'Alcohol and noodle' dietary patterns were derived from a factor analysis, and the subjects were divided into tertiles by each dietary pattern score. A logistic multiple regression analysis showed that the balanced diet pattern was negatively associated with blood levels of lead before and after adjustment. On the other hand, the alcohol and noodle pattern was positively associated with blood lead and mercury levels. These results indicate that the alcohol and noodle dietary pattern characterized by high alcohol consumption and lack of various foods, and the balanced dietary pattern, including vegetable, fish, meat and milk intake, was associated with the blood concentrations of heavy metals in Korean adults.
本研究旨在评估韩国成年人的饮食模式与血铅和血汞水平之间的关系。本研究共纳入了 858 名参加韩国国家健康和营养调查（KNHANES）V-1 2010 年的韩国成年人（≥20 岁）。本研究获得了包括血铅和血汞水平、营养素摄入和人体测量学指标在内的生化测量数据。采用因子分析得出“均衡饮食”、“谷物和泡菜”和“酒精和面条”三种饮食模式，根据每种饮食模式评分将研究对象分为三分位组。逻辑多元回归分析显示，均衡饮食模式与调整前后的血铅水平呈负相关。另一方面，酒精和面条模式与血铅和血汞水平呈正相关。这些结果表明，以高酒精摄入和缺乏各种食物为特征的酒精和面条饮食模式，以及包括蔬菜、鱼类、肉类和牛奶摄入的均衡饮食模式，与韩国成年人血液中重金属浓度有关。
