“…Studies using vital statistics have tried to assess the independent risk of mortality for an infant born at 37 and 38 weeks compared to 40 weeks age after adjusting for maternal medical and pregnancy conditions, obstetric complications and history of prior preterm birth (3,11). There appears to be no change in the increased risk after adjustment.…”

Objective Term pregnancy (37–41 weeks of gestation) is generally regarded as a uniform period for pregnancy outcome. The purpose of this study was to estimate the trend of maternal racial/ethnic differences in mortality for early term (37 0/7 – 38 6/7 weeks of gestation) compared to full term births (39 0/7 – 41 6/7 weeks of gestation). Methods We analyzed 46,329,018 singleton live births using the National Center for Health Statistics (NCHS) U.S. period-linked birth/infant death data from 1995 to 2006. Infant mortality rates (IMR), neonatal mortality rates (NMR), and postneonatal mortality rates (PNMR) were calculated according to gestational age, race/ethnicity, and cause of death. Results Overall, IMR has decreased for early term and full term births between 1995 and 2006. At 37 weeks of gestation, Hispanics had the greatest decline in IMR, 35.4% (4.8/1000 to 3.1/1000), followed by 22.4% for whites (4.9/1000 to 3.8/1000),whereas blacks had the smallest decline, 6.8% (5.9/1000 to 5.5/1000), due to a stagnant NMR. When 37 weeks is compared to 40 weeks of gestation, NMR is increased : Hispanics: RR= 2.6 (95% CI 2.0–3.3); whites: RR= 2.6 (95% CI 2.2–3.1); and blacks: RR= 2.9 (2.2–3.8). There is still excess NMR at 38 weeks of gestation. At both early and full term gestations, NMR is 40% higher and PNMR is 80% higher for blacks whereas Hispanics have a reduced PNMR when compared to whites. Conclusion Early term births are associated with higher NMR, PNMR, and IMR compared to full term births, with concerning racial/ethnic disparity in rates and trends.

“…Low birth weight is mainly caused by preterm birth, defined as delivery < 37 weeks of pregnancy, and fetal growth retardation (Xu et al 2011). Many studies showed that crucial factors of infant mortality, such as low birth weight and gestational age, are associated with increased infant mortality (Callaghan et al 2006; Donovan et al 2010; Were and Bwibo 2009). In a study in Korea, exposure to air pollution during pregnancy was significantly associated with preterm birth (Ha et al 2004) and low birth weight (Ha et al 2001; Lee et al 2003).…”

BackgroundSeveral studies suggest that airborne particulate matter (PM) is associated with infant mortality; however, most focused on short-term exposure to larger particles.ObjectivesWe evaluated associations between long-term exposure to different sizes of particles [total suspended particles (TSP), PM ≤ 10 μm in aerodynamic diameter (PM10), ≤ 10–2.5 μm (PM10–2.5), and ≤ 2.5 μm (PM2.5)] and infant mortality in a cohort in Seoul, Korea, 2004–2007.MethodsThe study includes 359,459 births with 225 deaths. We applied extended Cox proportional hazards modeling with time-dependent covariates to three mortality categories: all causes, respiratory, and sudden infant death syndrome (SIDS). We calculated exposures from birth to death (or end of eligibility for outcome at 1 year of age) and pregnancy (gestation and each trimester) and treated exposures as time-dependent variables for subjects’ exposure for each pollutant. We adjusted by sex, gestational length, season of birth, maternal age and educational level, and heat index. Each cause of death and exposure time frame was analyzed separately.ResultsWe found a relationship between gestational exposures to PM and infant mortality from all causes or respiratory causes for normal-birth-weight infants. For total mortality (all causes), risks were 1.44 (95% confidence interval, 1.06–1.97), 1.65 (1.18–2.31), 1.53 (1.22–1.90), and 1.19 (0.83–1.70) per interquartile range increase in TSP, PM10, PM2.5, and PM10–2.5, respectively; for respiratory mortality, risks were 3.78 (1.18–12.13), 6.20 (1.50–25.66), 3.15 (1.26–7.85), and 2.86 (0.76–10.85). For SIDS, risks were 0.92 (0.33–2.58), 1.15 (0.38–3.48), 1.42 (0.71–2.87), and 0.57 (0.16–1.96), respectively.ConclusionsOur findings provide supportive evidence of an association of long-term exposure to PM air pollution with infant mortality.

“…[3][4][5][6][7][8][9][10][11] Establishing breastfeeding in the late preterm infant is frequently more problematic than in the full-term infant. Because of their immaturity, late preterm infants may be sleepier and have less stamina and more difficulty with latch, suck, and swallow than a full-term infant.…”

A central goal of The Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient. These guidelines are not intended to be all-inclusive, but to provide a basic framework for physician education regarding breastfeeding.
