摘要

背景:对原住民和托雷斯海峡岛民(以下简称原住民)的识别不足会导致对健康结果的估计不准确。目的:比较仅使用西澳大利亚州助产士通知系统(MNS)中的怀孕数据和卫生部制定的土著身份标志(ISF)的三种土著身份确认方法:这项基于人群的回顾性队列研究利用逻辑回归法确定哪些人口特征与识别不足有关,以及确定方法对围产期不良结局的影响:所有方法都确定了 19 017 名(83.0%)土著妇女的核心群体,ISF 确定了 2298 名(10.0%)未使用任何其他方法确定的妇女。如果妇女的原住民身份是通过在 MNS 数据中曾被记录为原住民来确定的,则确定不足的比例最低;如果是根据有关分娩的记录来确定的,则确定不足的比例最高。产妇年龄无关联妊娠数据可用于原住民产科人群的流行病学研究。

Ascertainment of Aboriginal and Torres Strait Islander status for assessment of perinatal health outcomes: Reported versus derived maternal ethnicity in Western Australian pregnancy data.

Background: Under-identification of Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal) people can result in inaccurate estimation of health outcomes. Data linkage has improved identification of Aboriginal people in administrative datasets.

Aim: To compare three methods of ascertainment of Aboriginal status using only pregnancy data from the Western Australian Midwives Notification System (MNS), to the linked Indigenous Status Flag (ISF) derived by the Department of Health.

Materials and methods: This retrospective population-based cohort study utilised logistic regression to determine which demographic characteristics were associated with under-identification, and the effect of ascertainment method on perinatal adverse outcomes.

Results: All methods identified a core group of 19 017 (83.0%) Aboriginal women and the ISF identified 2298 (10.0%) women who were not identified using any other method. Under-ascertainment was lowest when a woman's Aboriginal status was determined by ever being recorded as Aboriginal in the MNS data, and highest when taken as it had been recorded for the birth in question. Maternal age <20 years, smoking during pregnancy, pre-existing diabetes, a history of singleton preterm birth and being in the lowest 20% of Socio-Economic Indexes for Areas score were all associated with a higher chance of being identified by the methods using only the MNS. These methods were less likely to identify nulliparous women, and those with maternal age ≥35 years. The method of ascertainment of Aboriginality did not make a significant difference to the adjusted predicted marginal probabilities of adverse perinatal outcomes.

Conclusion: Unlinked pregnancy data can be used for epidemiological research in Aboriginal obstetric populations.
