We assessed the accuracy and reliability of maternal recall of infant birth weight 35 to 70 years after delivery.
A total of 120 well functioning women (mean age 80 years; 45% Black) reported the birth weight for each live birth and then provided documentation of birth weights (n = 22) or reported birth weights a second time (n = 98).
Agreement between recalled and documented birth weights was high for first births (ICC = 0.96) but moderate for subsequent births (ICC = 0.59). Maternal recall was highly reliable for first births (r = 0.95) and subsequent births (r = 0.87), and reliability remained high when considered separately by race, education, income, and age.
Women report accurate and reliable infant birth-weight data an average of 57 years after delivery, and recall is particularly precise for first births.
我们评估了产后35至70年母亲回忆婴儿出生体重的准确性和可靠性。
共有120名功能良好的女性（平均年龄80岁；45%为黑人）报告了每次活产的出生体重，然后提供了出生体重的文件记录（n = 22）或再次报告出生体重（n = 98）。
首次分娩时回忆的出生体重与记录的出生体重之间的一致性较高（组内相关系数ICC = 0.96），但后续分娩时一致性中等（ICC = 0.59）。母亲对首次分娩的回忆高度可靠（r = 0.95），对后续分娩的回忆也可靠（r = 0.87），按种族、教育程度、收入和年龄分别考虑时，可靠性仍然很高。
女性在分娩后平均57年报告的婴儿出生体重数据准确可靠，且对首次分娩的回忆尤为精确。
