Little is known about pregnancy outcomes of black immigrant women to the US. We surveyed 447 black women post-partum in two hospitals in Newark, NJ. Length of gestation was obtained from medical records. Covariates and information on immigration were collected by in-person interview. Risks ratios for preterm birth (< 37 weeks) comparing immigrant to US-born women were calculated using log-binomial regression. Associations with gestational age at delivery were estimated using linear regression. Multivariable models adjusted for socioeconomic and social/behavioral variables. Immigrant women relative to US-born women had a 60% lower risk of preterm birth (adjusted risk ratio = 0.4; 95% confidence interval (CI) 0.2, 0.8) and longer gestation (adjusted difference = 1.4 weeks, 95%CI 0.6, 2.1). Gestation was 1.9 weeks longer for recent immigrants compared to US-born women (95%CI 0.2, 3.6), whereas for those who lived in the US for at least 10 years there was no difference. The healthy immigrant effect found among black immigrants may erode with time in the US.
关于美国黑人移民女性的妊娠结局知之甚少。我们调查了新泽西州纽瓦克市两家医院的 447 名产后黑人女性。妊娠期长度从病历中获得。通过面对面访谈收集协变量和移民信息。使用对数二项式回归计算比较移民和美国出生女性的早产（<37 周）风险比。使用线性回归估计与分娩时胎龄的关联。多变量模型调整了社会经济和社会/行为变量。与美国出生的女性相比，移民女性早产的风险降低了 60%（调整后的风险比=0.4；95%置信区间 0.2，0.8），妊娠期延长了 1.4 周（95%置信区间 0.6，2.1）。与美国出生的女性相比，最近移民的女性的妊娠期长 1.9 周（95%置信区间 0.2，3.6），而在美国生活至少 10 年的移民则没有差异。在黑人移民中发现的健康移民效应可能会随着在美国的时间而逐渐减弱。
