OBJECTIVE
To estimate the prevalence and determinants of use of vitamin and mineral supplements among adult Canadians.
METHODS
Data from adult respondents of the Canadian Community Health Survey Cycle (CCHS) 2.2 were used. Participants were asked about their use of vitamin and mineral supplements in the month prior to being surveyed. The prevalence of vitamin and mineral supplement use was compared across various socio-demographic and lifestyle factors. Logistic regression analysis was used to assess determinants of supplement use.
RESULTS
In the month prior to the interview, 40.1% of adult Canadians took supplements. In the fully adjusted model, females of all ages were more likely to be users than males 19-30 years. Physical activity, fruit/vegetable consumption, and higher levels of household education and income were positively related to supplement use.
CONCLUSIONS
A substantial proportion of adult Canadians take vitamin and mineral supplements. The use was more prevalent among those with healthier lifestyles and of socio-economically advantaged backgrounds. Further investigation is needed to reveal the impact of supplements on nutrient adequacy and health.
目的
估计加拿大成年人使用维生素和矿物质补充剂的流行率及其决定因素。
方法
使用加拿大社区健康调查周期（CCHS）2.2 中成年受访者的数据。受访者被问及在接受调查前一个月是否使用维生素和矿物质补充剂。比较了各种社会人口和生活方式因素之间维生素和矿物质补充剂使用的流行率。使用逻辑回归分析评估了补充剂使用的决定因素。
结果
在接受采访前的一个月，40.1%的加拿大成年人服用了补充剂。在完全调整后的模型中，各年龄段的女性比 19-30 岁的男性更有可能成为使用者。身体活动、水果/蔬菜的摄入以及更高的家庭教育和收入水平与补充剂的使用呈正相关。
结论
相当一部分加拿大成年人服用维生素和矿物质补充剂。在生活方式更健康和社会经济地位较高的人群中，使用更为普遍。需要进一步调查以揭示补充剂对营养充足性和健康的影响。
