LOW BIRTH WEIGHT ACROSS GENERATIONS

关于母婴出生关系的原始描述 紧随其后的是对大的 母亲出生体重和巨型(&gt；4000克)婴儿的分娩。 其他胎儿生长参数的研究，包括身长和头部 周长，表明低出生体重母亲的婴儿 都比体型较大的母亲的婴儿更矮更轻，但 婴儿的比例正常。 在相关研究中，田纳西州出生的婴儿的出生证明在 1979至1984年间，与他们母亲出生在 田纳西州1959至1966年间。母婴出生体重分别为 再一次被证明是相关的。此外，那些本身就属于下层社会的女性 出生体重高达4倍的孕妇可能会有较小的胎儿 婴儿的年龄与体重4000-4499克的妇女一样，但出生体重较低 女性早产的可能性不到两倍。一群 研究对象是1955至1965年间出生的瑞典女性。女性本身 出生时胎龄较小的人生孩子的风险更高 对于胎龄和早产儿来说都很小。早产的妇女 出生时发生这两种结果的风险都不会增加。 1960年出生的女孩S作为受试者的随访 合作围产期项目和丹麦围产期研究目前 目前正在进行研究，以检查它们的生育史。小号For 已经找到了孕周、早产和对照女孩 采访过了。他们分娩的医院记录也被 已取回。

The original description of the association of maternal and infant birth weights was followed by the description of the association between large maternal birth weight and delivery of a macrosomic (>4000 gram) infant. Study of other fetal growth parameters, including length and head circumference, demonstrated that infants of low birth weight mothers were both shorter and lighter than infants of larger mothers, but that the infants were normally proportioned. In related studies, birth certificates of infants born in Tennessee between 1979 to 1984 were matched with those of their mothers, who were born in Tennessee between 1959 to 1966. Maternal and infant birth weights were again shown to be correlated. In addition, women who were themselves of low birth weight were up to 4 times as likely to have a small for gestational age infant as were women weighing 4000-4499 grams, but the low birth weight women were less than twice as likely to have a preterm infant. A group of Swedish women, born from 1955 to 1965, was studied. Women themselves smaller gestational age at birth were at increased risk of giving birth to both small for gestational age and preterm infants. Women who were preterm at birth were not at increased risk of either outcome. Follow-up of girls who were born in the 1960's as subjects in the Collaborative Perinatal Project and Danish Perinatal Study is currently underway in order to examine their reproductive histories. Small for gestational age, preterm and control girls have been located and interviewed. Hospital records of their confinements have also been retrieved.
