          Abstract

          Background

          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.

          Methods

          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.

          Results

          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.

          Conclusions

          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.

          Factors associated with dietary supplement use among healthy adults of five ethnicities: the Multiethnic Cohort Study.

          Participants of the Multiethnic Cohort Study in Hawaii and Los Angeles, California, a representative sample of African-American, Native Hawaiian, Latino, Japanese-American, and White adults, completed a baseline questionnaire in 1993-1996 assessing dietary supplement use during the past year as well as demographic, dietary, and other lifestyle factors. Factors associated with supplement use were examined among those who reported an absence of chronic disease (n = 100,196). Use of any of eight supplements at least once per week during the past year ranged from 44% among Hawaiian men to 75% among Japanese-American and White women. Multivitamins were the most frequently reported supplement; 48% of the men and 56% of the women reported regular use. Dietary supplement use was high across all ethnic groups, although levels and length of regular use varied. In all gender-specific ethnic groups, supplement use tended to increase with age, education, physical activity, fruit intake, and dietary fiber intake and to decrease with obesity, smoking, and dietary fat intake. Participants whose lifestyles were healthier were more likely to use dietary supplements. Therefore, it may be difficult to separate the effects of supplement use from other lifestyle factors when studying disease etiology.

            Use of vitamin, mineral, nonvitamin, and nonmineral supplements in the United States: The 1987, 1992, and 2000 National Health Interview Survey results.

            To describe trends in use of specific vitamin and mineral (VM) supplements. The nationally representative National Health Interview Survey queried adult respondents about their use of VM supplements in 1987, 1992, and 2000. Statistical analysis Trends in use of VM supplements from 1987 to 2000 were determined using linear contrasts. The percentage of adults using any VM supplement daily increased from 23.2% (1987) to 23.7% (1992) to 33.9% (2000). This pattern was consistent for both sexes, all race/ethnic groups, and adults aged >or=25 years. The increase in the percentage of daily users of multivitamins, vitamin A, and vitamin E was 10.5, 1.2, and 7.3 percentage points, respectively, from 1987 to 2000. Increases in daily use of vitamin C (3.3 percentage points) and calcium (6.1 percentage points) occurred between 1992 and 2000. All trend analyses were significant at P<.001. In the 2000 National Health Interview Survey personnel queried the use of nonvitamin/nonmineral supplements for the first time. At that time, 6.0% of respondents reported using them daily. The increasing trend in supplement use over time and the notable use of nonvitamin/nonmineral supplements in 2000 indicates the continued need to monitor the use of all types of dietary supplements for purposes of dietary surveillance and nutrition-related research.
