To ascertain the component of the excess preterm birth (< 37 weeks, PTB) rate among US-born (compared to foreign-born) Black women attributable to differences in acknowledged father's education attainment.
Stratified analyses and Oaxaca-Blinder decomposition methods were performed on the 2013 National Center for Health Statistics birth certificate files of singleton infants with acknowledged fathers.
US-born Black women (N = 196,472) had a PTB rate of 13.3%, compared to 10.8% for foreign-born Black women (N = 51,334; Risk Difference (95% confidence interval) = 2.5 (2.3, 2.8). Infants of US-born black women had a greater a percentage of fathers with a high school diploma or less and a lower percentage of fathers with bachelor's degrees or higher than their counterparts of foreign-born women. In both subgroups, PTB rates tended to decline as the level of paternal education attainment rose. In an Oaxaca model (controlling for maternal age, education, marital status, parity, adequacy of prenatal care utilization, and chronic medical conditions), differences in paternal education attainment explained 15% of the maternal nativity disparity in PTB rates. In contrast, maternal education attainment accounted for approximately 4% of the disparity in PTB rates.
Acknowledged father's low level of education attainment, or something closely related to it, explains a notable proportion of the disparity in PTB rates between US-born and foreign-born Black women.
确定美国出生（与外国出生相比）黑人女性中早产率（<37 周，PTB）过高的原因，这归因于公认父亲受教育程度的差异。
对有公认父亲的单胎婴儿 2013 年国家卫生统计中心出生证明文件进行分层分析和 Oaxaca-Blinder 分解方法。
美国出生的黑人女性（N=196472）的 PTB 率为 13.3%，而外国出生的黑人女性（N=51334）为 10.8%（风险差异（95%置信区间）=2.5（2.3，2.8）。与外国出生的女性相比，美国出生的黑人女性的婴儿有更高比例的父亲只有高中学历或更低学历，而有更高学历（如学士学位或更高学历）的父亲比例较低。在这两个亚组中，随着父亲受教育程度的提高，PTB 率往往呈下降趋势。在 Oaxaca 模型中（控制母亲年龄、教育、婚姻状况、生育次数、产前保健利用充分性和慢性疾病状况），父亲教育程度的差异解释了 PTB 率母源性差异的 15%。相比之下，母亲的教育程度仅占 PTB 率差异的 4%左右。
承认父亲受教育程度低，或与之密切相关的因素，解释了美国出生和外国出生的黑人女性之间 PTB 率差异的相当大比例。
