What Causes Racial Disparities in Very Preterm Birth? A Biosocial Perspective

Open access
Kramer, M. R., Hogue, C. R.·2009·Epidemiologic Reviews

Abstract

Very preterm birth (<32 weeks' gestation) occurs in approximately 2% of livebirths but is a leading cause of infant mortality and morbidity in the United States. African-American women have a 2-fold to 3-fold elevated risk compared with non-Hispanic white women for reasons that are incompletely understood. This paper reviews the evidence for the biologic and social patterning of very preterm birth, with attention to leading hypotheses regarding the etiology of the racial disparity. A systematic review of the literature in the MEDLINE, CINAHL, PsycInfo, and EMBASE indices was conducted. The literature to date suggests a complex, multifactorial causal framework for understanding racial disparities in very preterm birth, with maternal inflammatory, vascular, or neuroendocrine dysfunction as proximal pathways and maternal exposure to stress, racial differences in preconceptional health, and genetic, epigenetic, and gene-environment interactions as more distal mediators. Interpersonal and institutionalized racism are mechanisms that may drive racially patterned differences. Current literature is limited in that research on social determinants and biologic processes of prematurity has been generally disconnected. Improved etiologic understanding and the potential for effective intervention may come with better integration of these research approaches.

  • Many studies demonstrate an association between stress or depression and preterm birth, while others suggest racial disparity is an underlying factor.

    “Although many studies demonstrate an association [10-15] others suggest that racial disparity [14,16,17] is an underlying factor.”

    From The association between parity, infant gender, higher level of paternal education and preterm birth in Pakistan: a cohort study (2011) · cites this paper as [17]

    The ‘Epidemiology of stress and prematurity’ passages report associations between stress and preterm birth and describe black–white differences in risk. They also report that accounting for experiences of discrimination reduced the black–white disparity. The paper treats racial disparity as an outcome to explain, however, rather than establishing the disparity itself as an underlying cause of preterm birth. (LLM, conf=0.78)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
