Although many health care professionals (HCPs) in the United States have been educated about and recommend dietary supplements, little is known about their personal use of dietary supplements and factors associated with their use.
We surveyed HCPs at the point of their enrollment in an on-line course about dietary supplements between September, 2004 and May, 2005. We used multivariable logistic regression to analyze demographic and practice factors associated with use of dietary supplements.
Of the 1249 health care professionals surveyed, 81 % reported having used a vitamin, mineral, or other non-herbal dietary supplements in the last week. Use varied by profession with highest rates among nurses (88%), physician assistants or nurse practitioners (84 %) and the lowest rates among pharmacists (66%) and trainees (72%). The most frequently used supplements were multivitamins (60%), calcium (40%), vitamin B (31%), vitamin C (30%), and fish oil (24%). Factors associated with higher supplement use were older age, female, high knowledge of dietary supplements, and discussing dietary supplements with patients. In our adjusted model, nurses were more likely than other professionals to use a multivitamin and students were more likely to use calcium.
Among HCPs enrolled in an on-line course about dietary supplements, women, older clinicians, those with higher knowledge and those who talk with patients about dietary supplements had higher use of dietary supplements. Additional research is necessary to understand the impact of professionals' personal use of dietary supplements on communication with patients about them.
尽管美国许多医疗保健专业人员（HCPs）已接受过关于膳食补充剂的教育并推荐使用膳食补充剂，但对于他们个人使用膳食补充剂的情况以及与其使用相关的因素却知之甚少。
我们在2004年9月至2005年5月期间，对参加关于膳食补充剂在线课程的HCPs进行了调查。我们使用多变量逻辑回归分析与膳食补充剂使用相关的人口统计学和实践因素。
在接受调查的1249名医疗保健专业人员中，81%报告在过去一周内使用过维生素、矿物质或其他非草药类膳食补充剂。使用情况因职业而异，护士中使用率最高（88%），医师助理或执业护士中使用率为84%，药剂师（66%）和实习生（72%）中使用率最低。最常使用的补充剂是多种维生素（60%）、钙（40%）、维生素B（31%）、维生素C（30%）和鱼油（24%）。与较高补充剂使用率相关的因素包括年龄较大、女性、对膳食补充剂了解程度高以及与患者讨论膳食补充剂。在我们的校正模型中，护士比其他专业人员更有可能使用多种维生素，学生更有可能使用钙。
在参加关于膳食补充剂在线课程的HCPs中，女性、年长的临床医生、知识水平较高的人员以及与患者谈论膳食补充剂的人员膳食补充剂使用率较高。有必要进行更多研究以了解专业人员个人使用膳食补充剂对与患者就这些补充剂进行沟通的影响。
