Prevalence of complementary and alternative medicine (CAM)-use in UK paediatric patients: a systematic review of surveys

Abstract

Aim: This systematic review is aimed at estimating the prevalence of complementary and alternative medicine (CAM)-use by paediatric populations in the United Kingdom (UK).

Method: AMED, CINAHL, COCHRANE, EMBASE and MEDLINE were searched for English language peer-reviewed surveys published between 01 January 2000 and September 2011. Additionally, relevant book chapters and our own departmental files were searched manually.

Results: Eleven surveys were included with a total of 17,631 paediatric patients. The majority were of poor methodological quality. Due to significant heterogeneity of the data, a formal meta-analysis was deemed inappropriate. Ten surveys related to CAM in general, while one was specifically on homeopathy. Across all surveys on CAM in general, the average one-year prevalence rate was 34% and the average lifetime prevalence was 42%. In surveys with a sample size of more than 500, the prevalence rates were considerably lower than in surveys with the sample size of lower than 500. Herbal medicine was the most popular CAM modality, followed by homeopathy and aromatherapy.

Conclusions: Many paediatric patients in the UK seem to use CAM. Paediatricians should therefore have sufficient knowledge about CAM to issue responsible advice.
