Abstract

Aims: The sex ratio at birth approximates 0.515 (male : total, M/T), with 515 boys per 485 girls. Many factors have been shown to influence M/T including acute and chronic stress. Increasing maternal age is associated with a decline in M/T. In Aotearoa New Zealand, circa 15% of the population identify as of Māori heritage. This populationis generally considered to be socioeconomically disadvantaged. This study analysed M/T for Māori and non-Māori M/T births in Aotearoa New Zealand and relates these to mean maternal age at delivery.

Methods: Live births by sex and maternal age at delivery were available from the website of Tatauranga Aotearoa Stats NZ for 1997-2021.

Results: This study analysed 1,474,905 births (28.4% Māori) Pooled data shows that Māori M/T is significantly higher than non-Māori M/T (chi = 6.8, p = 0.009). Mean maternal age at delivery was less for Māori mothers but this was not statistically significant.

Conclusions: Several studies have shown that M/T is decreased in socioeconomically deprived populations, and for this reason Māori M/T is expected to be lower and not higher than non-Māori M/T. A lower mean maternal age at delivery might have explained the M/T differences noted in this analysis but this was not a statistically significant difference.

出生性别比在Māori比在Non-Māori新西兰奥特罗阿的人口。

目的:出生性别比约为0.515(男性:总数，男/女)，每485个女孩对应515个男孩。许多因素已被证明影响M/T，包括急性和慢性压力。产妇年龄的增加与结核感染率的下降有关。在新西兰奥特罗阿，大约15%的人口被认定为Māori遗产。这一人群通常被认为在社会经济上处于不利地位。本研究分析了新西兰奥特罗阿(Aotearoa) Māori和non-Māori产妇的孕产率，并将其与产妇平均分娩年龄联系起来。方法:从1997-2021年新西兰taauranga Aotearoa Stats网站上获取按性别和产妇分娩年龄分列的活产。结果:本研究共分析1474905例新生儿(28.4% Māori)，汇总数据显示Māori M/T显著高于non-Māori M/T (chi = 6.8, p = 0.009)。Māori母亲的平均分娩年龄较低，但这没有统计学意义。结论:多项研究表明，社会经济贫困人群的M/T下降，因此，Māori M/T预计将低于而不高于non-Māori M/T。较低的产妇平均分娩年龄可能解释了本分析中注意到的M/T差异，但这在统计学上并不显着。
