['To determine whether spiritual and religious identities predict complementary and alternative medicine (CAM) use above and beyond other known influences such as gender, region of residence, social status, personality, health, and access to conventional medicine.', 'Analyzing data from the 1995-1996 National Survey of Midlife Development in the United States (n=3032), this study examines the correlations between four aspects of spirituality/religiousness-i.e., spiritual only, religious only, both spiritual and religious, and neither spiritual nor religious-and six measures of CAM.', 'Compared with spiritual only persons, the odds of using energy therapies are 86% lower for spiritual and religious persons, 65% lower for religious only persons, and 52% lower for neither spiritual nor religious persons. Compared to spiritual only persons, spiritual and religious individuals are 43% more likely to use body-mind therapies in general; however, when this category does not contain prayer, meditation, or spiritual healing, they are 44% less likely. Religious only individuals are disinclined toward CAM use.'] Do spiritual and religious identities predict the use of complementary and alternative medicine among US adults?
