Personal behaviors including food consumption and mineral supplement use among Japanese adults: a secondary analysis from the National Health and Nutrition Survey, 2003-2010

背景与目的：每天补充矿物质对有缺乏风险的人是有用的。一些西方的报告表明：矿物质补充剂使用者拥有健康的行为，并且没有矿物质缺乏。但在有不同饮食文化的日本，是否也存在同样的现象还不知道。本研究的目的是探讨2003-2010年全国健康与营养调查中矿物质补充者食物消费的个人行为特点。方法与研究设计：从16275名年龄为20-59岁完成社会人口学、健康状况和一天家庭膳食评估的成人中获得资料。补充剂使用者与未使用者进行比较。采用logistic回归模型确定食物消费、钙和铁补充剂使用的特点，以中等摄入量组作为参考。结果：总体而言，分别有2.1%和1.4%的成人使用钙和铁补充剂。钙补充剂的使用者比不用者更倾向于锻炼身体、不抽烟和少吃脂肪。此外，他们比不补充者更可能从茶叶、蔬菜、海藻和水果等食物中摄入更多的钙。铁补充者比不补充者更可能不吸烟，这些人往往摄入大量的海藻和水果。结论：日本有健康行为的成人更可能使用矿物质补充剂，尤其是钙。不论矿物质补充剂使用者总矿物质的消费量是多少，他们更倾向于选择海藻和水果等健康的食物。

Background and Objectives: A daily mineral supplement is useful for those who are at risk of a deficiency. Some Western reports suggest that mineral supplement users have healthy behaviors and are not mineral-deficient. It is unknown whether the same phenomenon is observed in Japan where there is a different dietary culture. The aim of this study was to examine the characteristics of personal behaviors including food consumption nationwide among mineral supplement users from the National Health and Nutrition Survey in Japan 2003-2010. Methods and Study Design: Data were obtained from 16,275 adults aged 20-59 years who completed sociodemographic, health status, and 1-day household dietary assessments. Supplement users were compared with non-users. Logistic regression models were utilized to identify the characteristics of food consumption and calcium and iron supplement use, using the medium intake group as a reference. Results: Overall, 2.1% and 1.4% of adults reported using calcium supplements and iron supplements, respectively. Calcium supplement users were more likely to be physically active, non-smokers, and eat less fat compared with non-users. Furthermore, they were more likely than non-users to consume a higher intake of calcium from foods such as tea, vegetables, seaweeds, and fruits. Iron supplement users were more likely than non-users to be non-smokers. These individuals tended to have a high intake of seaweeds and fruits. Conclusions: Japanese adults who had healthier behaviors were more likely to use mineral supplements, especially calcium. Mineral supplement users tended to choose healthy foods such as seaweeds and fruits, without considering their overall mineral consumption.
