Growing up healthy in families across the globe: cross-cultural harmonization of childhood riskfactors using longitudinal studies from Ireland, Scotland and New Zealand

The Growing Up Healthy in Families Across the Globe project is an international collaboration examining the potential for harmonised analysis using five longitudinal studies (from New Zealand, Ireland and Scotland). All five studies follow the lives of children, are interested in the dynamics of family change and work to inform policy to potentially improve population well-being across the lifecourse. Comparative analysis from harmonised longitudinal studies, where change over time is emphasised, provides a unique view to determine how and why environments change, which environments are supportive and which are not. This paper discusses the challenges and tasks involved when preparing and conducting harmonised analysis, and initial findings from the Growing Up Healthy project are discussed.
