Iodine Status of Mother-Infant Dyads from Montreal, Canada: Secondary Analyses of a Vitamin D Supplementation Trial in Breastfed Infants.

ABSTRACT:

Background

Most pregnant or lactating women in Canada will not meet iodine requirements without iodine supplementation.

Objectives

To assess the iodine status of 132 mother-infant pairs based on secondary analyses of a vitamin D supplementation trial in breastfed infants from Montréal, Canada.

Methods

Maternal iodine status was assessed using the breastmilk iodine concentration (BMIC). Singleton, term-born infants were studied from 1-36 months of age. Usual (adjusted for within-person variation) iodine intakes were estimated from urinary iodine and creatinine concentrations. Iodine status was assessed using median urinary iodine concentrations (UICs) and by estimating inadequate intakes by the cut-point method using a proposed Estimated Average Requirement for infants
