Public use in the US

A 2002 survey of US adults 18 years and older conducted by the National Center for Health Statistics (CDC) and the National Center for Complementary and Alternative Medicine indicated:

• 74.6% had used some form of complementary and alternative medicine (CAM).
• 62.1% had done so within the preceding twelve months.
• When prayer specifically for health reasons is excluded, these figures fall to 49.8% and 36.0%, respectively.
• 45.2% had in the last twelve months used prayer for health reasons, either through praying for their own health or through others praying for them.
• 54.9% used CAM in conjunction with conventional medicine.
• 14.8% "sought care from a licensed or certified" practitioner, suggesting that "most individuals who use CAM prefer to treat themselves."
• Most people used CAM to treat and/or prevent musculoskeletal conditions or other conditions associated with chronic or recurring pain.
• "Women were more likely than men to use CAM. The largest sex differential is seen in the use of mind-body therapies including prayer specifically for health reasons".
• "Except for the groups of therapies that included prayer specifically for health reasons, use of CAM increased as education levels increased".
• The most common CAM therapies used in the US in 2002 were prayer (45.2%), herbalism (18.9%), breathing meditation (11.6%), meditation (7.6%), chiropractic medicine (7.5%), yoga (5.1%), body work (5.0%), diet-based therapy (3.5%), progressive relaxation (3.0%), mega-vitamin therapy (2.8%) and Visualization (2.1%)

In the state of Texas, physicians may be partially protected from charges of unprofessional conduct or failure to practice medicine in an acceptable manner, and thus from disciplinary action, when they prescribe alternative medicine in a complementary manner, if board specific practice requirements are satisfied and the therapies utilized do not present "a safety risk for the patient that is unreasonably greater that the conventional treatment for the patient's medical condition."
