Birthweight and gestational age estimates made by research subjects were compared with values obtained from birth certificates and hospital records. Ninety-one per cent of mothers' estimates of their infant's birthweight and 88 per cent of their estimates of infant gestational age agreed with the delivery record. When the same mothers estimated their own and their husband's birthweight, only 44 per cent were in agreement with birth certificate values; however, 78 per cent were in agreement with the pounds portion of the weight. Agreement of mothers' estimates of her own and her husband's gestational age with birth certificates was no better than chance.
将研究对象所做的出生体重和孕周估计值与出生证明及医院记录中获取的值进行了比较。91%的母亲对其婴儿出生体重的估计以及88%的母亲对婴儿孕周的估计与分娩记录相符。当同样这些母亲估计她们自己和丈夫的出生体重时,只有44%与出生证明上的值一致;然而,78%与体重的磅数部分一致。母亲对自己和丈夫孕周的估计与出生证明的一致性并不比随机情况更好。
