Pediatric data on the use of natural health products (NHP) is scarce and there are underlying methodological issues with much of the body of research that has been conducted. The variety of data collection methodologies employed, dissimilarity in populations studied and lack of a consistent definition of complementary or alternative medicine (CAM) across studies means that making comparisons or making meaningful sense of results can be difficult. The objectives of this study are to a) determine the proportion of children using NHP; why parents give them to the children and whether the family doctor is aware of this NHP use, and b) to determine family physicians' general awareness, attitudes and knowledge about the use of NHPs in children. This will be carried out through physician and parent surveys, a chart audit, as well as semi-structured interviews with parents and physicians. All physician and patient questionnaires, and chart audits have been completed. Interviews are ongoing and will continue over the coming months.
