Abstract

Aim: To examine low birth weight (LBW) in First Nations babies born in a large metropolitan health service in Queensland, Australia.

Materials and methods: A retrospective population-based study using routinely collected data from administrative data sources. All singleton births in metropolitan health services, Queensland, Australia of ≥20 weeks gestation or at least 400 g birthweight and had information on First Nations status and born between 2019 and 2021 were included. The study measured birthweight and birthweight z-score, and also identified the predictors of LBW. Multivariate regression models were adjusted by demographic, socioeconomic and perinatal factors.

Results: First Nations babies had higher rates of LBW (11.4% vs 6.9%, P < 0.001), with higher rates of preterm birth (13.9% vs 8.8%, P < 0.001). In all babies, the most important factors contributing to LBW were: maternal smoking after 20 weeks of gestation; maternal pre-pregnancy underweight (body mass index <18.5 kg/m2); nulliparity; socioeconomic disadvantage; geographical remoteness; less frequent antenatal care; history of cannabis use; pre-existing cardiovascular disease; pre-eclampsia; antepartum haemorrhage; and birth outcomes including prematurity and female baby. After adjusting for all contributing factors, no difference in odds of LBW was observed between First Nations and non-First Nation babies.

Conclusions: First Nations status was not an independent factor influencing LBW in this cohort, after adjustment for identifiable factors. The disparity in LBW relates to modifiable risk factors, socioeconomic disadvantage, and prematurity. Upscaling culturally safe maternity care, focusing on modifiable risk factors is required to address LBW in Australian women.

在一个大都市的医疗服务机构中,原住民婴儿与出生体重过轻没有独立联系。
目的:研究在澳大利亚昆士兰州一个大都市医疗服务机构出生的原住民婴儿的低出生体重(LBW)情况:这是一项基于人口的回顾性研究,使用了从行政数据源中定期收集的数据。研究纳入了澳大利亚昆士兰州大都市医疗服务机构中所有妊娠期≥20周或出生体重至少为400克、有原住民身份信息且在2019年至2021年间出生的单胎新生儿。该研究测量了出生体重和出生体重 Z 值,并确定了低出生体重儿的预测因素。多变量回归模型根据人口、社会经济和围产期因素进行了调整:结果显示:原住民婴儿的畸形婴儿率较高(11.4% vs 6.9%,P 2);无胎儿;社会经济状况不佳;地理位置偏远;产前护理次数较少;有吸食大麻史;原有心血管疾病;先兆子痫;产前出血;以及包括早产和女婴在内的分娩结局。在对所有诱因进行调整后,观察到原住民婴儿和非原住民婴儿发生低体重儿的几率没有差异:结论:在对可识别因素进行调整后,原住民身份并不是影响该队列中低产婴儿的独立因素。低体重儿的差异与可改变的风险因素、社会经济劣势和早产有关。要解决澳大利亚妇女的低体重问题,就必须扩大文化安全孕产护理,重点关注可改变的风险因素。
