Science Update: Short interval between pregnancies may increase health risks for mothers and infants
Compared to younger mothers, mothers over 35 are at higher risk of death and serious illness if they conceive 6 months or less after the birth of a previous child, according to a study funded in part by the National Institutes of Health. For mothers of all ages, such short intervals between pregnancies were associated with higher risk for preterm birth and for having infants small for their gestation age.
