Life checks have been proposed by the English Department of Health as a personalised service providing support and advice at key stages throughout the lifespan to help people to maintain and improve their health. For young people, the proposed key stage for a life check is the transition between primary and secondary school sat ages 11 to 12 years. This review was a scoping exercise to identify the size and scope of the available research evidence relevant to the life check proposal for young people. This systematic review was published by EPPI-Centre in 2007. Systematic reviews aim to find as much as possible of the research relevant to the particular research questions, and use explicit methods to identify what can reliably be said on the basis of these studies.
