Objective: The primary aim of this study was to characterize the rate of adverse pregnancy outcomes in a multicultural group of low-income women. Methods: Data were extracted from the Montreal Diet Dispensary's database between June 2013 and December 2015. Risk was evaluated using logistic regression adjusted for covariates. Results: Of the 1,387 pregnancies, the prevalence of gestational diabetes mellitus (GDM) was 17.2% (95% confidence interval [CI], 15.1% to 19.3%), maternal anemia 44.9% (95% CI, 41.9% to 47.9%) and hypertension 3.8% (95% CI, 2.8% to 4.8%). The prevalence of small-for-gestational-age infants was 5.5% (95% CI, 4.3% to 6.7%), preterm births 4.7% (95% CI, 3.6% to 5.9%), low birthweight 4.2% (95% CI, 3.1% to 5.2%) and large-for-gestational-age infants was 10.6% (95% CI, 9.0% to 12.2%). Asian women had an increased odds of gestational diabetes mellitus (adjusted odds ratio [aOR], 1.86; 95% CI, 1.17 to 2.98) and SGA infants (aOR, 2.35; 95% CI 1.21 to 4.57) compared with white women. Anemia was more likely for black women compared with white women (aOR, 1.74; 95% CI, 1.29 to 2.35). Black women were more at risk of preterm birth (aOR, 1.79; 95% CI, 1.01 to 3.19). Immigrants showed an increased risk of maternal anemia compared with Canadian-born women (aOR, 1.85; 95% CI, 1.06 to 3.21). Conclusions: As disparities in maternal and infant outcomes were present, nutritional intervention(s) need to be targeted toward prevention of adverse pregnancy outcomes, prioritization of higher-risk groups and adaptation of the program to a multiethnic low-income population. © 2019 Canadian Diabetes Association
