Since its inception, the chiropractic care of children has been an integral part of the practice of chiropractic. Today, the chiropractic care of children remains an important aspect in chiropractic practice. In 2007, Barnes and colleagues estimated the complementary and alternative medicine use among U.S. adults and children from the 2007 National health interview survey, conducted by the centers for disease control and prevention's (CDC) National Center for Health Statistics (NCHS). Barnes and colleagues found that approximately one in nine children use some type of CAM therapy with children having a greater likelihood of using biologically based therapies, mind body therapies or manipulative and body-based therapies than other alternative healthcare approaches. Of the practitioner-based CAM therapies, the investigators found that chiropractic was the most popular form of non-allopathic healthcare for children.
