Life-course predictors of mortality inequalities across ethnic groups in Aotearoa New Zealand.

Socio-economic position and changes in this across the life-course have been established internationally to influence mortality, but this research has not occurred in the New Zealand context. Using mortality records linked with the New Zealand longitudinal census dataset, my thesis will investigate existing validated life-course hypotheses to understand which model best explains the socio-economic status and mortality relationship in Aotearoa. The four models are: accumulation (i.e. that the socio-economic influence on mortality accumulates across the life-course), sensitive period (i.e. that the effect of socio-economic experiences on mortality are stronger at some life stages than others), social mobility (i.e. that directional change in socio-economic circumstances impact mortality) and instability (i.e. that unstable socio-economic conditions over the life-course will be associated with mortality). Differences across ethnicities in terms of unstable environments or long-term exposure to harsh conditions will then be investigated to consider their relationship to ethnic disparities in mortality (i.e. higher mortality for Māori and Pacific peoples than for NZ Europeans). This project will take place within the wider context of a project being run in The University of Auckland’s COMPASS Centre, which is being funded by the Health Research Council.
