The association of parity and infant mortality was studied using linked birth-death files for 46,985 infants born to 11- to 19-year-old Minnesota residents between 1980 and 1988. Compared with infants of primiparas, infants of multiparas were at twice the risk for infant and postneonatal death but at no increased risk for neonatal death. They were also at two to three times the risk for deaths due to accidents, infections, and sudden infant death syndrome. The higher sociodemographic disadvantage and poorer prenatal care of multiparas did not explain the excess infant mortality risk that was concentrated in causes of death that are potentially preventable through primary care and parent education.
利用1980年至1988年间明尼苏达州11至19岁居民的46,985例出生与死亡关联档案，研究了产次与婴儿死亡率之间的关系。与初产妇的婴儿相比，经产妇的婴儿出现婴儿死亡和新生儿后期死亡的风险是前者的两倍，但新生儿死亡风险并未增加。他们因意外事故、感染和婴儿猝死综合征导致死亡的风险也是前者的两到三倍。经产妇较高的社会人口学劣势和较差的产前护理，并不能解释集中在通过初级保健和家长教育可能预防的死因上的过高婴儿死亡风险。
