The Use of Magnets, Magnetic Fields, and Copper Devices in a Veteran Population.

Background: Complementary and alternative medicine (CAM) use is increasing in the US and throughout the world. The use of magnets, magnetic fields, and copper devices (MMFC) for health care are CAM therapies. Available information suggests significant consumer spending on MMFC therapy, but minimal information exists on usage patterns.

Methods: We created a brief questionnaire and distributed it to veteran patients at the Carl T. Hayden Veterans Affairs Medical Center infusion center in Phoenix, Arizona. The questionnaire categorized respondents by age groups, diagnostic groups by specialty (endocrinology, gastroenterology, hematology/oncology, neurology, rheumatology, and other), and whether MMFCs were being used and for what purpose. The questionnaire also asked whether the respondent would consider participating in a clinical study using MMFCs.

Results: Analyzing the 206 evaluable surveys, we found an overall use rate of about 1 in 4 respondents. The majority used copper devices, and the endocrinology group showed the highest percentage use. Many veterans reported that they would consider participating in MMFC clinical studies. For interest in clinical trial participation, the age groups with the highest response for magnets in clinical trials was 31 to 50 years (64%), and for magnetic fields 51 to 65 years (52%).

Conclusions: About 25% of surveyed veterans reported the use of MMFCs. Veterans reported that they are likely to participate in clinical studies using these CAM therapies.
