Official health statistics are usually reported by M\u0101ori ethnicity but not descent, as health collections such as the New Zealand\nCancer Registry (NZCR) do not record M\u0101ori descent information. We explored the potential of linked administrative data to describe\nhealth outcomes by M\u0101ori descent using gastric (stomach) cancer as an example.\nmethods: The Integrated Data Infrastructure (IDI) was used to source information on M\u0101ori descent from the 2013 and 2018 censuses\nas well as birth and death records linked to the NZCR for gastric cancer registrations for the years 1995\u20132021 (N=10,575).\nresults: M\u0101ori descent information could be sourced for 81.8% of gastric cancer registrations. Descent information was available for\n65.2% of gastric cancer registrations in death records, 39.5% in the 2013 or 2018 census, 6.1% from a child\u2019s birth record and \u22640.3%\nfrom personal birth records. Of the registrations for whom M\u0101ori descent information could be obtained, 18.6% were identified as\nbeing of M\u0101ori descent vs 17.3% identified as M\u0101ori by ethnicity. Missing M\u0101ori descent data was lower (around 5%) in more recent\ngastric cancer registrations (2012 onwards).\nconclusion: Based on our case study, classifying cancer registrations by M\u0101ori descent for health outcome reporting, in addition\nto M\u0101ori ethnicity, may be feasible for recent years of data. Use of death records for M\u0101ori descent information should be carefully\nconsidered, as this may introduce bias to analyses such as survival analysis.<\/jats:p>","DOI":"10.26635\/6965.6844","type":"journal-article","created":{"date-parts":[[2025,4,30]],"date-time":"2025-04-30T02:24:23Z","timestamp":1745979863000},"page":"81-90","source":"Crossref","is-referenced-by-count":0,"title":["Applying Indigenous identity definitions in official health statistics: a case study using linked cancer registry data on stomach cancer"],"prefix":"10.26635","volume":"138","author":[{"given":"Nicole","family":"Satherley","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brandon","family":"de Graaf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabrielle","family":"Davie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheree","family":"Gibb","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Teng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Sporle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"11177","published-online":{"date-parts":[[2025,5,2]]},"container-title":["New Zealand Medical Journal"],"original-title":[],"deposited":{"date-parts":[[2025,4,30]],"date-time":"2025-04-30T02:24:29Z","timestamp":1745979869000},"score":1,"resource":{"primary":{"URL":"https:\/\/nzmj.org.nz\/journal\/vol-138-no-1614\/applying-indigenous-identity-definitions-in-official-health-statistics-a-case-study-using-linked-cancer-registry-data-on-stomach"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,5,2]]},"references-count":0,"journal-issue":{"issue":"1614","published-online":{"date-parts":[[2025,5,2]]}},"URL":"https:\/\/doi.org\/10.26635\/6965.6844","relation":{},"ISSN":["1175-8716"],"issn-type":[{"value":"1175-8716","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,5,2]]}}}
