Many people utilize mainstream medicine for diagnosis and basic information, while turning to alternatives for what they believe to be health-enhancing measures. However, studies indicate that a majority of people use alternative approaches in conjunction with conventional medicine.
Edzard Ernst wrote in the Medical Journal of Australia that "about half the general population in developed countries use complementary and alternative medicine (CAM)." A survey released in May 2004 by the National Center for Complementary and Alternative Medicine, part of the National Institutes of Health in the United States, found that in 2002, 36% of Americans used some form of alternative therapy in the past 12 months, 50% in a lifetime — a category that included yoga, meditation, herbal treatments and the Atkins diet. If prayer was counted as an alternative therapy, the figure rose to 62.1%. 25% of people who use CAM do so because a medical professional suggested it. Another study suggests a similar figure of 40%. A British telephone survey by the BBC of 1209 adults in 1998 shows that around 20% of adults in Britain had used alternative medicine in the past 12 months.
The use of alternative medicine appears to be increasing. A 1998 study showed that the use of alternative medicine had risen from 33.8% in 1990 to 42.1% in 1997. In the United Kingdom, a 2000 report ordered by the House of Lords suggested that "...limited data seem to support the idea that CAM use in the United Kingdom is high and is increasing."
