Abstract
The period 1980–2000 was important for infant health in the United States. During this time, dramatic social change and substantial improvements in medical perinatal care produced striking improvements in infant health and survival. Despite overall declines in infant mortality from all causes some evidence has suggested that relative racial disparities have persisted and even widened during this period. While the maternal socio-demographic factors associated with these racial disparities are well-established, several points remain unclear. First, there is some uncertainty regarding which causes have contributed to the widening racial disparities in infant mortality. Second, it is uncertain how the changing social context may have affected these patterns. Finally, it is unknown which has been more influential, changes in the social context or changes in maternal socio-demographic characteristics.

Notes
- 1.
Without knowing specific cause of death, it is difficult to theorize about the individual contribution of factors associated with infant mortality. For example, area-level poverty isn’t likely to have a strong influence on deaths due to congenital anomalies. Since infants with congenital anomalies tend to die within minutes of birth, factors that influence the home environment of infants don’t usually have much effect on the infant when the infant doesn’t even come home from the hospital. Conversely, community-level variables that measure “rurality” or distance to medical facilities are likely to have a strong impact on deaths due to birth asphyxia (which occur when a woman experiences problems during delivery that delay the birth of the infant). If it takes a pregnant woman a significant amount of time from when her water breaks to when she gets care at a hospital, she faces increased risk of losing her infant due to birth asphyxia. Distance to a hospital is not likely to affect the health of an infant born with a congenital anomaly.

Birth weight is often considered a proxy for prematurity, where the lightest infants are gestationally the most immature. While some (Frisbie et al. 1997) have made the distinction between the etiologies leading to low birthweight as a result of prematurity versus low birthweight as the result of intrauterine growth restriction (IUGR), the majority of research on infant health and survival equates low birthweight with prematurity.

While we present regression coefficients in Table 7.3, we discuss them in terms of odds ratios in the narrative. We calculated odds ratios by hand, by exponentiating them, using the formula e x.
