Delayed childbearing and risk of adverse perinatal outcome

Article Abstract:

Older women are less likely to give birth to healthy babies than are younger women. First time mothers over age 30 tend to be white middle class and upper middle class women who receive prenatal and antenatal care early. Even in uncomplicated pregnancies, women over aged 30 had 40% greater risk of fetal death than women ages 20 to 24. They also had more moderately and very low birthweight babies. Those having preterm deliveries rose with age. At age 40, the rates were twice that of women ages 20 to 24. Mothers over age 35 delivered twice as many babies who were small for their gestational age. Researchers adjusted results for maternal education, hypertension, diabetes, prenatal hemorrhage, smoking habits and biological father living with the mother. Previous infertility problems were not associated with increased risk of late fetal or early neonatal death.

Prevalence and Predictors of the Prone Sleep Position Among Inner-city Infants

Article Abstract:

Educational programs are needed to convince low-income mothers not to place their young infants on their stomach to sleep. This sleep position has been shown to increase the risk of sudden infant death syndrome (SIDS). Researchers interviewed 394 mostly low-income, inner-city mothers shortly after delivery and again 3 to 7 months later. At 3 to 7 months of age, 40% of the infants were placed on their stomachs to sleep. Poor black women were most likely to do this, especially if they saw their infant on its stomach in the hospital nursery.

Prepregnancy weight and the risk of adverse pregnancy outcomes

Article Abstract:

A woman's weight prior to pregnancy may affect the growth and survival of her fetus. Researchers in Sweden reviewed the medical records of 167,750 women who gave birth in 1992 and 1993. Obese women had a significantly higher risk of fetal death late in pregnancy, but larger women had lower rates of delivering small babies. Results were somewhat different in women having their first baby. These findings may affect body-weight recommendations for pregnancy in both overweight women and in those who are very lean.
