Abstract
When information on the gestational age at birth is needed, and hospital records are unavailable, or too costly or time-consuming to obtain, retrospective maternity surveys or reports are used to estimate the expected date of delivery (EDD). Several studies have compared the accuracy of maternal reporting of gestational age by comparison with gestational age in medical records, but the results have been mixed.
The aim of this study was to compare gestational age estimated from maternal reporting of EDD 9 months after delivery, with gestational age reported in routine hospital records. Another study aim was to determine whether perinatal and sociodemographic factors influenced agreement, and whether the potentially observed disagreement affected classification of preterm birth.
Data on 8058 singleton infants from the UK Millennium Cohort Study were examined. Agreement between the maternal report and hospital data was 72.2% with respect to exact gestational age in completed weeks and 94.5% for agreement within 1 week of hospital-based gestational age. Disagreement was more common among infants who were not firstborn, women who had unplanned pregnancies or received late or no antenatal care, and had a low socioeconomic status. With maternal reporting of gestational age, slightly more children were classified as preterm than with gestational age based on hospital data (6.4% vs. 6.1%). There was also a poor agreement for postterm birth.
These findings suggest that retrospective maternal reporting of EDD is reliable based on its overall agreement within 1 week of the gestation recorded in routine hospital data.
