OBJECTIVE
To survey Canadian university students' vitamin D-related knowledge.
METHODS
Undergraduate university students (n = 1,088) were surveyed as to their vitamin D-related knowledge, including its sources, health benefits, and recommended intake.
RESULTS
Overall, students answered 29% of questions correctly on the knowledge test. In addition, the overall test was subdivided into 3 subtests, and students scored 26% on vitamin D source knowledge, 23% on factors affecting vitamin D levels, and 37% on health effects of vitamin D. Only 8% of participants correctly identified the recommended vitamin D intake; 14% correctly identified the amount of time in the sun required to produce adequate vitamin D.
CONCLUSIONS AND IMPLICATIONS
These results suggest that Canadian university students have poor knowledge concerning vitamin D. Program planners should consider improving vitamin D knowledge as a component of future health promotion programs for university students.
目的
调查加拿大大学生与维生素D相关的知识。
方法
对本科大学生（n = 1088）进行了关于其维生素D相关知识的调查，包括维生素D的来源、健康益处及推荐摄入量。
结果
总体而言，学生在知识测试中正确回答了29%的问题。此外，总体测试被细分为3个分测试，学生在维生素D来源知识方面得分为26%，在影响维生素D水平的因素方面得分为23%，在维生素D对健康的影响方面得分为37%。只有8%的参与者正确识别了维生素D的推荐摄入量；14%的参与者正确识别了产生足够维生素D所需的日照时间。
结论与启示
这些结果表明加拿大大学生对维生素D的知识了解不足。项目规划者应考虑将提高维生素D知识作为未来大学生健康促进项目的一个组成部分。
