Use of complementary and alternative medicine by children in Europe: Published data and expert perspectives
Introduction
Complementary and alternative medicine (CAM) includes practices that are not an integral part of the conventional healthcare system, but are used by many patients to supplement their care.1 Particularly patients in western industrial nations show an increasing interest in using CAM to treat acute and chronic diseases.2, 3, 4 This rising interest includes both adults and children.1, 5, 6, 7 Professional organisations, such as American Academy of Pediatrics and the WHO, have begun to collect and publish information about which types of traditional and complementary medicine are used by certain patient groups.8, 9 Efforts to include education and training for CAM therapies in medical school programs and in healthcare institutions have also become popular in some European countries.10, 11
Europe covers approximately 10,180,000 km2 (3,930,000 sq. mi), consists of approximately 50 states and hosts a population of 731 million people. Europe is distinguished by its wide variety of languages, cultures and religions. This heterogeneity makes assessing CAM use and CAM training across Europe as a whole difficult. Exact numbers for the prevalence of CAM use in Europe are not available. Europe-wide surveys of CAM use by the public in general and not focussed on patients with a specific disease currently do not exist. The survey conducted by Molassiotis et al. gathered data for CAM use by cancer patients in 16 European countries using a descriptive investigation, and found that 36% of the cancer patients surveyed have used some form of CAM (range among countries: 15–73%).12 They identified a heterogeneous group of 58 therapies being used by cancer patients. Recent studies conducted in Europe report that CAM use by children is less common than by adult patients, but appears to be increasing in some European countries.9, 13, 14 Although there have been some recent efforts in singular European countries to investigate paediatric CAM usage and characterise the CAM user, an international comparative survey has not yet been done.15, 16, 17, 18 The aim of this survey was to present an overview about characteristics of CAM use in children in different European countries and to estimate the prevalence of CAM use by the population in general, and more specifically by children, in Europe despite the scarcity of peer-reviewed published surveys.

Methods
A narrative, non-systematic review was assembled by combining expert opinions with a thorough and balanced review of available evidence from the literature.19 An unrestricted literature search using the keywords, “alternative”, “complementary”, “integrative”, “prevalence” and “paediatric” or “children” was performed by internet search using PubMed and open accessible search engines. All European countries with a minimum of 5 million habitants were initially included for which any data about CAM
Results
We obtained data from 20 (72%) of the 29 European countries to which we made requests, and data were provided by at least one expert in each of these 20 countries. Thus, expertise was available concerning CAM use from countries with altogether more than 534 million inhabitants (69% of the total European population) and covering an area of 5,590,000 km2 (43% of Europe). Some data about CAM use by the general population was available from surveys for 18 of the 20 (90%) countries, but usually only
Discussion
Little is known about CAM use by children. This is especially true for Europe, since the bulk of the literature is derived from children living in the USA. Comprehensive European analyses of CAM use in paediatrics are scare, which may partly be due to the diversity of languages, alphabets, religions, biodiversity and the historical background of Europe. Here we present a pan-European review about CAM in paediatrics, realised by combining data published in international journals, data from local
