Meconium stained amniotic fluid commonly occurs postdates ( >40 weeks gestation) indicating fetal maturity. Previous literature indicates that different ethnicities mature at different rates.
To compare the rate of meconium stained amniotic fluid of Australian-born and non-Australian born women.
A retrospective correlation study design was implemented, using data collected in the birth outcomes system at one tertiary hospital. Data was collected from all women who gave birth to a term (>/=37 weeks gestation), singleton, liveborn baby between January 1st to December 31st, 2014. Maternal country of birth was used for comparison. Categorical data was analyzed using Chi-Square test for Independence. Continuous variables were assessed for normality, and differences were compared using an Independent t-test or a Mann-Whitney U test. All tests were two-tailed and p<0.05 was considered statistically significant.
3,041 women were included; 1131 Australian-born and 1910 non-Australian born. Meconium stained amniotic fluid occurred more frequently in non-Australian born women compared to Australian-born women (23.5% vs. 19.8 p=0.02). Their babies were significantly smaller (Mean=3265g, Standard Deviation 463.8 vs Mean=3442g, Standard Deviation 499.2, p<0.001), with no difference in gestational length (Mean=39.4, Standard Deviation 1.28 vs Mean=39.5, Standard Deviation 1.18, p=0.06). Increasing gestational age had the strongest association with meconium stained amniotic fluid; >/=42 weeks gestation occurring 3.52 (95% Confidence Interval: 2.00, 6.22, p=<0.001) more than <40 weeks gestation.
Maternity health services should record ethnicity and region of birth to provide individualised care as women born overseas often have poorer perinatal outcomes when compared to Australian-born women.
胎粪污染羊水通常发生在过期妊娠（>40 周）后，表明胎儿成熟。先前的文献表明，不同种族的成熟速度不同。
比较澳大利亚出生和非澳大利亚出生的妇女胎粪污染羊水的发生率。
采用回顾性相关性研究设计，使用一家三级医院出生结局系统收集的数据。数据收集于 2014 年 1 月 1 日至 12 月 31 日期间在该院分娩足月（>=37 周）、单胎、活产婴儿的所有妇女。比较母亲的出生国。使用卡方检验（Chi-Square test for Independence）分析分类数据。对连续变量进行正态性检验，使用独立 t 检验或曼-惠特尼 U 检验比较差异。所有检验均为双侧检验，p<0.05 为统计学显著差异。
共纳入 3041 名妇女；1131 名澳大利亚出生，1910 名非澳大利亚出生。与澳大利亚出生的妇女相比，非澳大利亚出生的妇女胎粪污染羊水的发生率更高（23.5% vs. 19.8%，p=0.02）。她们的婴儿明显更小（均值=3265g，标准差 463.8 vs 均值=3442g，标准差 499.2，p<0.001），但孕龄无差异（均值=39.4，标准差 1.28 vs 均值=39.5，标准差 1.18，p=0.06）。胎龄增加与胎粪污染羊水的相关性最强；>=42 周妊娠的发生率比<40 周妊娠高 3.52（95%置信区间：2.00，6.22，p<0.001）。
产妇保健服务应记录种族和出生地，为海外出生的妇女提供个性化护理，因为与澳大利亚出生的妇女相比，这些妇女的围产期结局往往较差。
