About us

SoFIE-Primary Care (SoFIE-PC) aims to investigate the associations and causal pathways between sociodemographic characteristics (e.g. ethnicity, socio-economic position, region) and primary care affiliation, access and continuity (PCAAC) using a longitudinal and nationally representative study (SoFIE) and SoFIE-Health.


  • What is the association of sociodemographic characteristics (e.g. ethnicity, socio-economic position, region) variables with access, continuity and coordination of primary health care.
  • What is the association of affiliation to a primary care provider, access, continuity and coordination of primary health care, with ambulatory sensitive hospitalisations and chronic disease states.
  • ∆ PCAAC ↔ ∆ health status: Are changes in PCAAC associated with changes in health status?
  • ∆ Social factors → ∆ PCAAC: What is the association of changing family circumstances (e.g. marital separation), changing labour force status, and changing income with changes in PCAAC?
  • ∆ Residence → ∆ PCAAC: What is the impact of changing residence (including changing rural/urban, changing levels of deprivation) on PCAAC?
  • Illness → ∆ PCAAC: What is the association of cancer diagnosis and hospitalisation for major illness on changes in PCAAC?


SoFIE-Primary Care is primarliy funded by the Health Research Council of New Zealand. Establishment funding was also received from the University of Otago, Accident Compensation Corporation of New Zealand (ACC), and Alcohol Liquor Advisory Council (ALAC).
