虽然各种族/族裔群体低出生体重发生率的差异是众所周知的，但种族/民族群体内产妇出生地的低出生体重发生率的差异，特别是经怀孕并发症调整后的差异就不那么明显了。我们对LBW进行了一项基于人口的研究，使用了华盛顿州金县(2008-2012)的113,760个独生子女的活出生记录，该地区位于太平洋西北部，拥有大量移民人口。研究参与者是亚洲人、非西班牙裔黑人、西班牙裔、夏威夷原住民/其他太平洋岛民(诺皮)和非西班牙裔白人女性。使用多变量Logistic回归模型，我们计算优势比(OR)和95%可信区间(CI)，以估计与母亲种族/民族和出生地(由千年发展目标区域分组定义)有关的LBW(<；2500g)的相对风险。与非西班牙裔白人妇女相比，非西班牙裔黑人、亚裔印度人、菲律宾人、日本人和越南妇女生下LBW婴儿的风险是1.57-2.23倍，具有统计学意义，而诺皮人和墨西哥妇女的风险是1.30-1.33倍，具有统计学意义。与出生在美国的种族/民族女性相比，来自东亚的亚洲女性(OR 0.68，95%CI 0.55-0.85)、撒哈拉以南非洲的非西班牙裔黑人女性(OR 0.58，95%CI 0.47-0.73)和其他发达国家的非西班牙裔白人女性(OR 0.83，95%CI 0.69-1.00)的LBW风险较低。总的来说，在对妊娠并发症进行调整后，结果是相似的。与大多数其他种族/民族相比，非西班牙裔白人患LBW的风险较低。在大多数种族/民族中，与在美国出生的女性相比，外国出生的女性患LBW的风险较低。妊娠并发症对这种联系的影响微乎其微。
While disparities in low birth weight (LBW) incidence by racial/ethnic group are well known, differences in LBW incidence by maternal birthplace within racial/ethnic groups, and particularly, differences after adjustment for pregnancy complications, are less clear. We conducted a population-based study of LBW using 113,760 singleton, live birth records from King County, Washington (2008–2012), a region in the Pacific Northwest with a large immigrant population. Study participants were Asian, non-Hispanic black, Hispanic, Native Hawaiian/Other Pacific Islander (NHOPI), and non-Hispanic white women. Using multivariable logistic regression models, we calculated odds ratios (ORs) and 95% confidence intervals (CIs) to estimate relative risk of LBW (<2,500 g) related to maternal race/ethnicity and birthplace (defined by the Millennium Development Goals Regional Groupings). Compared with non-Hispanic white women, non-Hispanic black, Asian Indian, Filipino, Japanese, and Vietnamese women had 1.57–2.23-fold higher, statistically significant, risk of having a LBW infant, and NHOPI and Mexican women had 1.30–1.33-fold, statistically significant, higher risk. LBW risk was lower for Asian women from Eastern Asia (OR 0.68, 95% CI 0.55–0.85), non-Hispanic black women from Sub-Saharan Africa (OR 0.58, 95% CI 0.47–0.73), and non-Hispanic white women from other developed countries (OR 0.83, 95% CI 0.69–1.00), as compared with their US-born racial/ethnic counterparts. Results were, in general, similar after adjustment for pregnancy complications. Compared with most other racial/ethnic groups, non-Hispanic whites had lower risk of LBW. Foreign-born women had lower risk of LBW compared with their US-born counterparts in the majority of racial/ethnic groups. Pregnancy complications had minimal effect on the associations.
