Secular Trends in Excess Fetal and Infant Mortality Using Perinatal Periods of Risk Analysis

Prematurity, the most frequent cause of infant mortality in Kansas City during 2001-2005 accounted for 42.5% of the infant deaths. Being a teenage mother; having less than a high-school education; being unmarried; having an unintended pregnancy; being obese preconceptually; being diabetic; using substances such as tobacco or drugs during pregnancy; receiving late, inadequate or intermediate amounts of prenatal care; having a multifetal pregnancy; having a primary elective cesarean section; delivering a preterm infant or having a male infant; and being enrolled in Medicaid all increased the risk of infant death.
