Association Between Maternal Fluoride Exposure During Pregnancy and IQ Scores in Offspring in Canada.

ABSTRACT:

Importance

The potential neurotoxicity associated with exposure to fluoride, which has generated controversy about community water fluoridation, remains unclear.

Objective

To examine the association between fluoride exposure during pregnancy and IQ scores in a prospective birth cohort.

Design, setting, and participants

This prospective, multicenter birth cohort study used information from the Maternal-Infant Research on Environmental Chemicals cohort. Children were born between 2008 and 2012; 41% lived in communities supplied with fluoridated municipal water. The study sample included 601 mother-child pairs recruited from 6 major cities in Canada; children were between ages 3 and 4 years at testing. Data were analyzed between March 2017 and January 2019.
