2007 Statistics on CAM Use in the United States

National Health Interview Survey

According to a nationwide government survey released in December 2008, approximately 38 percent of U.S. adults aged 18 years and over and approximately 12 percent of children use some form of CAM.

CAM is a group of diverse medical and health care systems, practices, and
products that are not generally considered part of conventional medicine. Complementary medicine is used together with conventional medicine, and alternative medicine is used in place of conventional medicine. Integrative medicine combines conventional and CAM treatments for which there is evidence of safety and effectiveness.
