Abstract
BACKGROUND: Despite a lack of good scientific evidence for their benefit, Canadians take a lot of natural health products (NHPs). The objectives of this study were to determine patients' perception of the efficacy, safety and quality of NHPs and to characterize NHP use. METHODS: A standardized, 18-question survey was distributed to the general public through a variety of methods. RESULTS: A total of 326 individuals completed the survey. Eighty-five percent of respondents take 1 or more NHPs. Forty-seven percent agreed/strongly agreed that NHPs are safer than prescription medications and 24% disagreed/strongly disagreed that prescription medications are more effective than NHPs. Three-quarters of respondents agreed/strongly agreed that health care providers should recommend NHPs more often, as most stated they preferred to take an NHP for both a minor ailment (82%) and chronic medical condition (60%). Respondents used 124 different NHPs, most commonly vitamin D, vitamin B and magnesium. Respondents purchased NHPs primarily from health/vitamin stores (66%) and accessed the Internet for information about them (64%). Younger, female respondents were more likely to take NHPs. DISCUSSION: Patients appear to be comfortable foregoing education from health care professionals about the benefits and risks of NHPs. Patients' comfort with self-prescribing NHPs seems to stem from a perception of general efficacy and quality with little to no concern about harm and appears to be strongly influenced by lay sources of information. CONCLUSION: Most respondents take 1 or more NHPs, preferring to use NHPs over prescription medications for minor and chronic health concerns seemingly based on a perception of safety and quality.
