New Statistics on Complementary and Alternative Medicine Use in the United States

Approximately 38 percent of adults in the United States aged 18 years and over and nearly 12 percent of U.S. children aged 17 years and under use some form of complementary and alternative medicine (CAM), according to a new nationwide government survey. This survey marks the first time questions were included on children's use of CAM, which is a group of diverse medical and health care systems, practices, and products such as herbal supplements, meditation, chiropractic, and acupuncture that are not generally considered to be part of conventional medicine.

The survey, conducted as part of the 2007 National Health Interview Survey (NHIS), an annual study in which tens of thousands of Americans are interviewed about their health- and illness-related experiences, was developed by the National Center for Complementary and Alternative Medicine (NCCAM), a part of the National Institutes of Health (NIH) and the National Center for Health Statistics (NCHS), a part of the Centers for Disease Control and Prevention (CDC). The survey included questions on 36 types of CAM therapies commonly used in the United States—10 types of provider-based therapies, such as acupuncture and chiropractic, and 26 other therapies that do not require a provider, such as herbal supplements and meditation.

"The 2007 NHIS provides the most current, comprehensive, and reliable source of information on Americans' use of CAM," said Josephine P. Briggs, M.D., director of NCCAM. "These statistics confirm that CAM practices are a frequently used component of Americans' health care regimens, and reinforce the need for rigorous research to study the safety and effectiveness of these therapies. The data also point out the need for patients and health care providers to openly discuss CAM use to ensure safe and coordinated care.
