Anonymous self-report surveys of a convenience sample of caregivers accompanying children to the pediatrician for acute or well visits at 4 pediatric practices in the Washington, DC area from July through November 1998 were evaluated. Three hundred seventy-eight (85%) of 443 caregivers approached participated. The 348 surveys completed by parents (92%) were analyzed. As previously reported, in this sample 21% of parents used complementary and alternative medicine (CAM) for their child. Overall, 53% of parents expressed the desire to discuss CAM with their pediatrician, increasing to 75% (p<0.001) among those who used CAM themselves and 81% (p<0.01) among those who used CAM for their child. Among parents who used CAM for their child, 36% had discussed it with their pediatrician. Factors associated with increased disclosure to the pediatrician were CAM use in children younger than 6 years (p<0.05), "bioenergetic" CAM use (p<0.02), and parent CAM non-use (p<0.05). Despite parents' significant interest in discussion about CAM, few factors were associated with adequate parent-pediatrician communication.
