Prevalence of Food Insecurity Among Pregnant Women: A Canadian Study in a Large Urban Setting

Objective: Nutritional and financial needs increase during pregnancy, making pregnant women particularly vulnerable to food insecurity. Our objective was to document the prevalence of food insecurity among pregnant women receiving prenatal care in an urban centre in Canada and to identify factors associated with food insecurity. Methods: This cross-sectional study recruited pregnant women receiving prenatal care at one of two Toronto hospitals: Site 1 and Site 2 (serving a more disadvantaged population) between October 1, 2018 and October 1, 2019. Demographic information was collected, and the U.S. Household Food Security Survey Module was used to assess food security. Comparisons were made using chi(2) tests, two-tailed t tests, or Mann-Whitney tests for categorical and continuous variables, as appropriate. Binary logistic regression and multivariate analyses were performed to assess associations with food insecurity and differences between hospitals sites. Results: We recruited 626 participants (316 at Site 1 and 310 at Site 2). Prevalence of food insecurity was 12.8% among all participants with Site 2 having nearly 5 times the prevalence of Site 1 (66/310 [21.3%] vs. 14/316 [4.4%]; P = 0.001). Several factors were associated with food insecurity, with non-White ethnicity (OR 2.04; 95% CI 0.98-4.25, P = 0.055] and lower household income (OR 37.53; 95% CI 14.04-100, P < 0.001 when less than CAD $23 000/y) being the most robust. Conclusion: This Canadian study documented the prevalence of and factors associated with food insecurity in pregnancy. Targeted interventions to help low-income women and programs geared towards non-White women may be beneficial in addressing food insecurity among pregnant women.
