LOW BIRTH WEIGHT ACROSS GENERATIONS

关于母婴出生关系的原始描述 权重之后是对两者之间的关联的描述 增加母亲的出生体重和接生混血儿(大于 4000克)婴儿。相比之下，体重在8磅或更多的母亲 出生时，体重在6到7.9磅之间的母亲出生的可能性只有一半，而且 体重4-5.9磅的母亲生孩子的可能性要高出15% 一个体型庞大的婴儿。为了进一步调查具体效果 孕妇出生体重与胎儿生长不成比例的关系，其他胎儿 使用来自协作性围产期的数据来研究生长参数 项目。低出生体重母亲的婴儿比低出生体重母亲的婴儿矮 体型较大的母亲，但通常比例较大。 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年出生的孩子与他们母亲的孩子匹配 田纳西州1959至1966年间。母亲和母亲之间的联系 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 对于胎龄儿来说，比早产儿要好。 一项正在进行的研究涉及提取一个样本的出生记录 20世纪50年代出生在瑞典一个地区的妇女S。 这些妇女的历史将通过出生登记处进行追踪。 最后，对1986年6月4日至5日的合同提案进行了审查 涉及建立和跟踪一群妇女，她们自己的 以前有过宫内和围产期经历的记录。 然后将确定这些妇女的生育结果。

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.
