Performance of a postnatal metabolic gestational age algorithm: a retrospective validation study among ethnic subgroups in Canada.

ABSTRACT:

Objectives

Biological modelling of routinely collected newborn screening data has emerged as a novel method for deriving postnatal gestational age estimates. Validation of published models has previously been limited to cohorts largely consisting of infants of white Caucasian ethnicity. In this study, we sought to determine the validity of a published gestational age estimation algorithm among recent immigrants to Canada, where maternal landed immigrant status was used as a surrogate measure of infant ethnicity.

Design

We conducted a retrospective validation study in infants born in Ontario between April 2009 and September 2011.

Setting

Provincial data from Ontario, Canada were obtained from the Institute for Clinical Evaluative Sciences.
