Health is today viewed as a multi-dimensional concept partly conceptualized independent from not being ill. The aim of this study was to gain knowledge of how young children perceive health. Interviews were conducted with 68 children (4–5 years), within their pre-school setting, with the help of a semi-structured interview guide. A multi-dimensional perspective represented by the health dimensions of the International Classification of Functioning, Disability and Health (ICF) was used in a manifest deductive content analysis. The children's statements were categorized and placed under one of the four health dimensions, body, activity, participation and environment. A latent content analysis was applied to identify underlying themes in the manifest categories. The results revealed that young children perceive health as a multi-dimensional construct, largely related to being engaged, i.e. to be able to perform wanted activities and participate in a supportive every-day context. This implies that improvements of child engagement should be emphasized in health promotion and to a greater extent be the central focus of health interventions for young children.
