In fact, if one considered just three factors (maternal education, maternal prenatal alcohol or tobacco, and marital status) one could predict to a high degree postneonatal mortality: children born to unmarried women with lower education and evidence of prenatal drug use had a postneonatal mortality of about 30 per 1000 live births (similar to Ivory Coast); children born to women
with none of these risk factors had a postneonatal mortality of about 2 per 1000 live births (similar to Norway); that is, children in this latter category almost never die despite evidence from PRAMS surveys that they are as likely to co-sleep with their parents.
