Study goals were to distinguish between maternal risk factors for fetal versus infant mortality, and to identify which maternal characteristics contributed the greatest risk of mortality overall. This case-control retrospective study abstracted data on more than forty maternal characteristics from 261 prenatal and delivery records: all 26 fetal deaths, all 40 infant deaths and 195 randomly selected surviving births in a high-mortality Healthy Start community. Bivariate and multivariate analyses were conducted. The fetal-mortality population was significantly more likely than the infant-mortality population to have no insurance (P = .047), inadequate prenatal care (P = .039) and previous fetal death (P = .021). Comparing the combined mortality population with the surviving sample, two tiers of risk emerged: Rare-but-lethal risks, including no prenatal care (P < .001) and Child-Protective-Service involvement (P = .001), and common-and-dangerous risks, including inadequate maternal weight gain (OR = 13.55), drug or alcohol abuse (OR = 8.67), obesity (OR = 2.77) and anemia (OR = 3.61). Both fetal and infant mortality groups must be considered when identifying maternal risks. Inadequate prenatal weight gain, obesity and anemia contribute as much to feto-infant mortality as substance abuse. Public health efforts to improve maternal nutrition and healthy weight should be redoubled.
