LOW BIRTH WEIGHT ACROSS GENERATIONS

母婴生育关联的原始描述 权重之后是对 增加产妇出生体重和分娩的mascrosomic（大于 4000克）婴儿。 与体重在8磅或以上的母亲相比， 出生时，体重6至7.9磅的母亲只有一半的可能性， 体重在4-5.9磅之间的母亲， 巨大的婴儿。 为了进一步研究具体的效果 母亲出生体重对胎儿生长不成比例的影响， 研究了生长参数，使用围产期合作组织的数据， 项目 低出生体重母亲的婴儿比 大的母亲，但通常比例。 在一项相关的研究中，田纳西州出生的婴儿的出生证明， 1979年和1984年出生的人与他们的母亲相匹配， 田纳西州，1959年至1966年。 母亲和母亲之间的关系 婴儿出生体重得到确认。 此外，还表明，低 母亲出生体重对分娩小婴儿的风险更大。 对于胎龄婴儿来说， 一项正在进行的研究涉及提取一个样本的出生记录， 1950年代出生在瑞典某地区的女性。 生殖 这些妇女的历史将通过出生登记册进行追踪。 最后，在1986年6月4日至5日对合同提案进行了审查 包括建立和跟踪一组妇女， 子宫内和围产期的经验已被记录。 然后将确定这些女性的生殖结果。

The original description of the association of maternal and infant birth weights was followed by the description of the association between increased maternal birth weight and delivery of a mascrosomic (greater than 4000 gram) infant. Compared to mothers who weighed 8 pounds or more at birth, mothers who weighed 6 to 7.9 pounds were only half as likely, and mothers who weighed 4-5.9 pounds were 15 percent as likely to give birth to a macrosomic infant. In order to further investigate the specific effect of maternal birth weight on disproportionate fetal growth, other fetal growth parameters were studied, using data from the Collaborative Perinatal Project. Infants of low birth weight mothers were shorter than infants of larger mothers, but were normally proportioned. In a related study, birth certificates of infants born in Tennessee between 1979 and 1984 were matched with those of their mothers, who were born in Tennessee between 1959 and 1966. The association between maternal and infant birth weight was confirmed. In addition, it was shown that low maternal birth weight carried a greater risk for the delivery of a small for gestational age infant than for a preterm one. An ongoing study involves abstraction of the birth records of a sample of women born in a region of Sweden during the 1950's. The reproductive histories of these women will be traced through the birth registry. Finally, review of proposals occurred in June 4-5, 1986 for a contract involving the establishment and follow-up of a cohort of women whose own intrauterine and perinatal experience has been previously documented. Reproductive outcome of these women will then be determined.
