“…The distinction between prevalence when spiritual and nonspiritual CAMs are included is important, as opinions and practices differ regarding whether spiritual practices should be considered as CAMs. For this reason, some studies exclude spiritual-based practices (American Association of Retired Persons, National Center for Complementary and Alternative Medicine, 2007;Matthews et al, 2007) whereas others report the results with and without spiritual-based practices (Barnes et al, 2002;Grzywacz et al, 2006). The analysis of the 2002 NHIS data for CAM use by US adults found that the most commonly used therapies were prayer for one's own health (43.0%), prayer by others for one's own health (24.4%), natural products (18.9%), deep breathing exercises (11.6%), participation in prayer group for one's own health (9.6%), meditation (7.6%), and chiropractic care (7.5%) (Barnes et al, 2004).…”
