Are migrants during the periconception period less likely to be supplementing with folic acid: An Australian cohort study.

Background: Folic acid (FA) supplementation before and in early pregnancy is known to improve outcomes such as reducing neural tube defects; however, little is known about groups in Australia at risk of low FA use.

Aim: To determine whether differences exist in FA supplementation rates between Australian-born women and migrant women, with a secondary aim of examining the sociodemographic characteristics of women who are not supplementing with FA in early pregnancy.

Methods: A retrospective cohort study from January 2018-July 2022 in a high-migrant population in Western Sydney, Australia.
