INTRODUCTION This study quantifies the differences in infant outcomes by mother's self-identified race among Arab Americans and by self-identified race and ethnicity for Arabs and non-Arabs. METHODS This study used data from the Standard Certificate of Live Birth on 8,204 infants born to Arab and 325,354 infants born to non-Arab mothers between 2012 and 2016 in Massachusetts; data were analyzed between 2019 and 2020. Mothers' race was categorized as White, Black, or Other. Mothers' ethnicity was categorized as Arab or non-Arab. Outcomes included birth weight, preterm birth, low-birth weight, small for gestational age, and large for gestational age. Linear and logistic regression models assessed the association between race and infant health outcomes. RESULTS Black Arab mothers had higher odds of preterm birth (AOR=1.37, 95% CI=1.07, 1.76) and low-birth weight (AOR=1.35, 95% CI=0.99, 1.84) than White Arab mothers. Arab mothers who self-identified as Other had babies that were 51.4 grams lighter than babies born to White Arab mothers. White Arab mothers had higher odds of low birth weight (AOR=1.19, 95% CI=1.06, 1.34) and small-for-gestational-age babies (AOR=1.22, 95% CI=1.11, 1.36) but lower odds of large-for-gestational-age babies (AOR=0.77, 95% CI=0.70, 0.86) than White non-Arab mothers. CONCLUSIONS Both ethnicity and race are important determinants of the health of Arab American infants. Arab ethnicity may play a negative role in the infant health of Arab Americans who identify as White. A better understanding of the lived experiences of Arab American mothers, with regard to their racial and ethnic identity, may help better inform clinical practice.
