Linked birth cohort files for perinatal health research: California as a model for methodology and implementation.

ABSTRACT:

Purpose

Rigorous perinatal epidemiologic research depends on population-based parental and neonatal sociodemographic and clinical data. Here we describe the creation of linked birth cohort files, an enriched data source that combines information from vital records with maternal delivery and infant hospital encounter records.
