Comparison of reproductive history gathered by interview and by vital records linkage after 40 years of follow-up: Bogalusa Babies.

ABSTRACT:

Background

To examine the consistency and likely degree of bias in a study of cardiovascular health, linked with reproductive data over 40 years.

Methods

Linkage of vital statistics data of births to female Bogalusa Heart Study participants was compared to interviewing of female participants. The characteristics of participants, the agreement, and demographic, study-related, and medical predictors of discrepancy were analyzed, using kappa statistics, mean and median differences, and logistic regression.

Results
