Tuan, Wen-JanHatfield, PeggyBhattacharya, AbhikSarto, Gloria EKling, Pamela JWisconsin infant mortality rates are largely driven by neonatal deaths. This shows an urgent need to develop effective public health interventions to prevent early neonatal deaths. To reduce racial/ethnic disparities in NMRs, the design of the interventions should also take into account the variation of the effects of birth weight and gestation age on neonatal mortality among racial/ethnic groups. It is hoped the result of this study will provide a critical understanding: when it comes to racial/ethnic disparities, there is far more to low birth weight or short gestational age than simply not having enough weight or days.DisparitiesPrenatal & Pediatric Healthinterventionsstudiesneonatal mortalityracial/ethnic disparitieslow birth weightshort gestational ageArticle
