比较了美国出生和外国出生的非西班牙裔黑人女性的早产率 (PTB) 和小于胎龄 (SGA)。还对撒哈拉以南非洲出生的黑人妇女和加勒比出生的黑人妇女以及这两个地区的出生国进行了比较。根据出生记录上的社会人口统计、健康行为和医疗风险因素对比较进行了调整。使用了记录了母亲出生国的所有州 (n = 27) 的出生记录数据 (2008)。这些数据占当年非西班牙裔黑人女性所有单胎出生的 58%。 Pearson 卡方和逻辑回归用于研究产妇分娩后 PTB 和 SGA 发生率的变化。在完全调整的模型中，与美国出生的非西班牙裔黑人女性相比，外国出生的非西班牙裔黑人女性的 PTB（OR 0.727；CI 0. 726，0.727）和 SGA（OR 0.742；CI 0.739-0.745）发生率显着较低。与加勒比地区出生的黑人女性相比，撒哈拉以南非洲出生的黑人女性的 PTB 和 SGA 发生率明显较低。在每个地区，PTB 和 SGA 的发生率因母亲的出生国而异。这些差异无法通过对从重要记录中获得的已知风险因素进行调整来解释。据记录，美国非西班牙裔黑人女性中产妇的 PTB 和 SGA 发生率存在相当大的异质性，但在调整已知风险因素后仍无法解释。
Rates of prematurity (PTB) and small-for-gestational age (SGA) were compared between US-born and foreign-born non-Hispanic black women. Comparisons were also made between Sub-Saharan African-born and Caribbean-born black women and by maternal country of birth within the two regions. Comparisons were adjusted for sociodemographic, health behavioral and medical risk factors available on the birth record. Birth record data (2008) from all states (n = 27) where mother's country of birth was recorded were used. These data comprised 58 % of all singleton births to non-Hispanic black women in that year. Pearson Chi square and logistic regression were used to investigate variation in the rates of PTB and SGA by maternal nativity. Foreign-born non-Hispanic black women had significantly lower rates of PTB (OR 0.727; CI 0. 726, 0.727) and SGA (OR 0.742; CI 0.739-0.745) compared to US-born non-Hispanic black women in a fully adjusted model. Sub-Saharan African-born black women compared to Caribbean-born black women had significantly lower rates of PTB and SGA. Within each region, the rates of PTB and SGA varied by mother's country of birth. These differences could not be explained by adjustment for known risk factors obtained from vital records. Considerable heterogeneity in rates of PTB and SGA among non-Hispanic black women in the US by maternal nativity was documented and remained unexplained after adjustment for known risk factors.
