Dietary supplements are regularly used by a majority of the American population, and usage by health professionals is also common. There is considerable interest in usage patterns within the population and in the reasons for using dietary supplements. The "Life...supplemented" Healthcare Professionals 2008 Impact Study (HCP Impact Study) surveyed usage of dietary supplements by physicians in three specialties: cardiology, dermatology, and orthopedics.
The HCP Impact Study was conducted online by Ipsos Public Affairs for the Council for Responsible Nutrition (CRN), a trade association of the dietary supplement industry. Respondents were 900 physicians, including 300 each from three specialties--cardiology, dermatology, and orthopedics.
Fifty-seven percent of cardiologists said they use dietary supplements at least occasionally, as did 75% of dermatologists and 73% of orthopedists. The product most commonly reported to be used was a multivitamin, but over 25% in each specialty said they used omega-3 fatty acids and over 20% said they used some botanical supplements. Regular dietary supplement use was reported by 37% of cardiologists, 59% of dermatologists, and 50% of orthopedists. Seventy-two percent of cardiologists, 66% of dermatologists, and 91% of orthopedists reported recommending dietary supplements to their patients. The primary reason given for recommending dietary supplements to patients was for heart health or lowering cholesterol for the cardiologists; benefits for skin, hair and nails for the dermatologists; and bone and joint health for the orthopedists.
Reported dietary supplement use was relatively common in this sample of physicians, and when they recommended dietary supplements to patients, they tended to do so for reasons related to their specialty.
大多数美国民众经常服用膳食补充剂，健康专业人士也经常服用。人们对人群中的使用模式以及使用膳食补充剂的原因很感兴趣。“Life...supplemented”医疗保健专业人员 2008 年影响研究（HCP 影响研究）调查了心脏病学、皮肤科和骨科三个专业的医生对膳食补充剂的使用情况。
HCP 影响研究由 Ipsos Public Affairs 代表膳食补充剂行业贸易协会——营养责任委员会（CRN）在线进行。受访者为 900 名医生，其中心脏病学、皮肤科和骨科各 300 名。
57%的心脏病学家表示他们至少偶尔会使用膳食补充剂，皮肤科医生和骨科医生的这一比例分别为 75%和 73%。报告中最常使用的产品是多种维生素，但每个专业都有超过 25%的医生表示他们使用欧米伽-3 脂肪酸，超过 20%的医生表示他们使用一些植物性补充剂。37%的心脏病学家、59%的皮肤科医生和 50%的骨科医生定期使用膳食补充剂。72%的心脏病学家、66%的皮肤科医生和 91%的骨科医生报告向患者推荐膳食补充剂。向患者推荐膳食补充剂的主要原因是心脏病学家为了心脏健康或降低胆固醇；皮肤科医生是为了皮肤、头发和指甲的健康；而骨科医生则是为了骨骼和关节健康。
在这个医生样本中，报告的膳食补充剂使用相对常见，当他们向患者推荐膳食补充剂时，他们倾向于根据与自己专业相关的原因推荐。
