The Equal-Life project will develop and test combined exposure data using a new approach to multi-modal exposures and their impact on children’s mental health and development. A combination of birth cohort data with new data sources will provide new insights into aspects of physical and social exposures. It will do this for a range of scales and time frames while accounting for the distribution of exposures in social groups based on gender, ethnicity and social vulnerability.
