We aim to quantify differences in clinical outcomes from COVID-19 infection in Aotearoa New Zealand by ethnicity and with a focus on risk of hospitalisation.
We used data on age, ethnicity, deprivation index, pre-existing health conditions and clinical outcomes on 1,829 COVID-19 cases reported in New Zealand. We used a logistic regression model to calculate odds ratios for the risk of hospitalisation by ethnicity. We also considered length of hospital stay and risk of fatality.
After controlling for age and pre-existing conditions, we found that Māori have 2.50 times greater odds of hospitalisation (95% CI 1.39-4.51) than non-Māori non-Pacific people. Pacific people have three times greater odds (95% CI 1.75-5.33).
Structural inequities and systemic racism in the healthcare system mean that Māori and Pacific communities face a much greater health burden from COVID-19. Older people and those with pre-existing health conditions are also at greater risk. This should inform future policy decisions including prioritising groups for vaccination.
我们旨在通过族裔群体来量化新西兰 COVID-19 感染的临床结果差异，并重点关注住院风险。
我们使用了新西兰报告的 1829 例 COVID-19 病例的年龄、族裔、贫困指数、既往健康状况和临床结果数据。我们使用逻辑回归模型计算了族裔群体住院风险的优势比。我们还考虑了住院时间和死亡风险。
在控制年龄和既往疾病后，我们发现毛利人住院的可能性是非毛利人和非太平洋岛民的 2.50 倍（95%CI 1.39-4.51）。太平洋岛民的可能性则是其三倍（95%CI 1.75-5.33）。
医疗保健系统中的结构性不平等和系统性种族主义意味着毛利人和太平洋岛民社区面临着更大的 COVID-19 健康负担。老年人和有既往健康状况的人也面临更大的风险。这应该为未来的政策决策提供信息，包括为接种疫苗的群体确定优先级。
