Discordance between LMP-based and clinically estimated gestational age : implications for research, programs, and policy.
This study examines the comparability between the last menstrual period-based and clinically estimated gestational age as collected on certificates of live birth.
It explores whether sociodemographic or delivery characteristics influence their agreement and contrasts health status and health care utilization indicators, such as preterm, small for gestational age, and adequacy of prenatal care percentages, produced by each gestational age measure.
The 1989-91 South Carolina public use live birth files were used for this analysis.
A total of 169,082 single births to resident mothers were selected for investigation.
The clinically estimated gestational age distribution exhibited a higher mean and a tendency toward even number digit preference.
The last menstrual period-based and the clinically estimated gestational age distributions exhibited notable dissimilarities, produced marked differences in health status indicators, and varied in concordance by gestational age and by sociodemographic, prenatal care, and hospital characteristics.
These systematic differences suggest that a transition from the traditionally used last menstrual period-based measure to the clinical estimate or a composite measure will not produce uniform results across geo-political areas and at-risk g.
