Racial and Ethnic Disparities in Preterm Birth Among American Indian and Alaska Native Women.

Objectives: Preterm birth disproportionately affects American Indian/Alaska Native (AI/AN) women. This disparity in birth outcomes may stem from higher levels of exposure to psychosocial, sociodemographic, and medical risk factors. Methods: This paper reviews relevant research related to preterm birth in American Indian and Alaska Native women. Conclusions: This narrative review examines disparities in preterm birth rates between AI/AN and other American women, and addresses several maternal risk factors and barriers that contribute to elevated preterm birth rates among this racial minority group. Additionally, this paper focuses on recent evidence that geographical location can significantly impact preterm birth rates among AI/AN women. In particular, access to care among AI/AN women and differences between rural and urban areas are discussed. [ABSTRACT FROM AUTHOR]
