Lay summary
There is extensive acknowledgement and evidence that ethnic gaps (particularly for Maori and Pacific Peoples) exist in the rates of GP registration, immunisation and dental checks. Underutilisation of these healthcare services may result in a number of adverse health outcomes in the long term. While there is some descriptive evidence available on the household and individual characteristics associated with the uptake of these services (particularly with respect to immunisation rates), there is currently no empirical research focused at understanding the relative contribution of potential drivers to the ethnic differences. This project will quantify the contribution of different factors (accessibility, mobility, socio-economic, parental and child characteristics) to ethnic differences at three longitudinal time points with a view to providing potential policy drivers to assist in closing these gaps.
