A probability sample survey of high-risk inner-city women with a live birth in the last 3 years shows that maternal medical risks and health behaviors during pregnancy are important intermediate variables influencing preterm delivery and birthweight. Women who developed two or more medical risks had about three-and-a-half times the risk of preterm delivery and two-and-a-half times the risk of low birthweight compared to those without such risks. Women with prior fetal loss had twofold increase in the risk of preterm delivery and low birthweight. Unintended pregnancy resulted in one-and-a-half to twofold increase in preterm delivery and low birthweight, respectively. Inadequate gestational weight increased the risk of preterm delivery by about 50%. Smoking during pregnancy raised the risk of low birthweight slightly more than one-and-a-half times.
一项对过去3年内有过活产经历的高危市中心区女性进行的概率抽样调查显示，孕期的孕产妇医疗风险和健康行为是影响早产和出生体重的重要中间变量。与没有此类风险的女性相比，出现两种或更多医疗风险的女性早产风险约为其三倍半，低出生体重风险约为其二倍半。有过胎儿丢失史的女性早产和低出生体重风险增加一倍。意外怀孕分别使早产和低出生体重风险增加半倍至一倍。孕期体重增加不足使早产风险增加约50%。孕期吸烟使低出生体重风险增加略超过半倍。
