However, evidence syntheses indicate that probiotic interventions, while effective in managing some pregnancy complications (e.g., gestational diabetes), do not confer health benefits to uncomplicated pregnancies. Messaging around probiotics in pregnancy is mixed, such that people with low-risk pregnancies may nevertheless feel pressure to spend limited resources on (costly) probiotics. To tailor knowledge exchange and support safe, equitable access to pregnancy probiotics when their prescription may be warranted, we need to understand who takes probiotics during pregnancy and under what conditions.</p></div><div><h3>Methods</h3><p>We used chi-square and logistic regression analyses of anonymous, cross-sectional survey data from 341 pregnant Canadians of diverse socio-demographic backgrounds to assess which respondents, by socio-demographic characteristics and pre-pregnancy/pregnancy health indicators, were relatively likely to: perceive probiotics as beneficial to pregnancy health and/or report taking probiotics during pregnancy.</p></div><div><h3>Results</h3><p>Forty-seven percent of respondents perceived probiotics as beneficial to pregnancy health; 51 % reported consuming them.
