NEW ORLEANS – More than 1 in 10 children (12%) have received complementary or alternative medicine (CAM), according to the 2012 National Health Interview Survey. It’s therefore vital that you are familiar with the options and evidence on these treatments, according to Cora Breuner, MD, a professor of pediatrics at the University of Washington, Seattle, and attending physician at Seattle Children’s Hospital.
“Use of CAM by a parent was strongly associated with the child’s use of CAM,” Dr. Breuner told attendees at the annual meeting of the American Academy of Pediatrics. Parents of children using CAM were more likely to have a college education and to use prescription medication, the National Health Interview Survey found, and teens were more frequent users of CAM than infants.
The most common conditions treated in children with CAM were back and neck pain, colds, anxiety, stress, ADHD, insomnia, and general musculoskeletal conditions or complaints. Fish oil, melatonin, probiotics, and chiropractic and osteopathic manipulation were used more frequently than any other CAM treatments, but Dr. Breuner’s presentation focused specifically on supplements, including vitamins and herbs.
of how lax the law is when it comes to the safety and effectiveness of vitamins, minerals, herbs, and other dietary supplements.
“Products can go on the market with no testing of efficacy, and companies do not have to prove that their products are safe – only offer reasonable assurance of safety,” Dr. Breuner explained. “Supplements do not have to be manufactured to any standards, and FDA [Food and Drug Administration] approval is not needed for package or marketing claims,” although the reputable manufacturers favor standards.
She cited a 2011 study of popular supplement products on the market that found 75% of them did not include key safety messages (BMC Med. 2011 Aug 9;9:94). The study focused on St. John’s wort, ginkgo, ginseng, garlic, and echinacea products, and it’s likely other products lack such safety information as well. Yet researchers have identified a wide range of potential adverse effects from herbal medicines (Clin Med [Lond]. 2013 Feb;13[1]:7-12).
Physicians and consumers can rely on a handful of voluntary standards and online databases to guide therapeutic decisions and learn more about the evidence on specific products. The U.S. Pharmacopeia Dietary Supplement Verification Program is a seal consumers can look for on supplement products that indicates the product meets stricter standards than what the FDA allows.
Other resources include ConsumerLab.com, the Natural Medicines Research Collaboration, and the Pubmed Dietary Supplement Subset database from the National Institute of Medicine. The latter contains more than 676,000 unique scientific citations on published studies about vitamins, minerals, and botanicals, Dr. Breuner said.
Dr. Breuner presented an overview of more than a dozen popular supplements that included their uses and the evidence related to their use. Although not exhaustive, her list included the most common supplements for which some research has been done: butterbur, caffeine, cannabidiol, coenzyme Q10, echinacea, magnesium, melatonin, N-acetylcysteine, omega 3 fatty acids, St. John’s wort, turmeric (curcumin), and zinc.
The findings from these studies, however, vary greatly, and the studies themselves are often small and limited to adults. Shared decision making is key in working with families interested in using CAM, and families should be aware that supplements can have side effects just as FDA-approved drugs do.
Dr. Breuner reported that she had no relevant financial disclosures.
