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 χ2 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.

Modulation of endothelial function by Korean red ginseng (Panax ginseng C.A. Meyer) and its components in healthy individuals: a randomized controlled trial.

AIMS: Ginseng root and its derivatives remain atop the most widely used medicinal herbs in cardiovascular disease, despite inadequate substantiation of efficacy. We previously reported the potential of Korean red ginseng (KRG) to affect vascular tone by decreasing arterial wave reflection via an unknown mechanism. Given the preclinical link between ginseng intake and vasoactivity related to nitric oxide (NO) production, we sought to directly evaluate the effects of KRG root and its major root components, on an established noninvasive measure of endothelial function. METHODS: In an acute, randomized, placebo-controlled, double-blind, crossover design, 16 healthy participants (9M:7F, age:30 ± 9y, BMI: 24 kg ±3 kg/m(2) , systolicBP/diastolicBP: 109 ± 11/66 ± 8 mmHg) on four occasions were administered: KRG root (3 g), KRG ginsenosides extract, KRG polysaccharides extract, and cornstarch control. Extracted fractions were delivered at doses bioequivalent to those found in 3 g of KRG. Flow-mediated vasodilatation (FMD) assessment, preceding a brachial blood pressure measurement, was performed at baseline and at 90 and 180 min posttreatment to assess endothelial function. RESULTS: KRG significantly improved FMD posttreatment. Maximal vasodilatation of Δ2.57 ± 2.8% occurred at 180 min compared with control (Δ-0.83 ± 2.7%, P = 0.003 for all comparisons). The ginsenoside extract produced a comparable response (Δ1.75 ± 2.6%), but not the polysaccharide fraction (Δ0.10 ± 2.7%). Brachial blood pressure remained unchanged for all treatments (P = 0.45). CONCLUSIONS: KRG acutely improved endothelial function in healthy individuals, which appears to be attributable to its ginsenoside containing fraction. Our data confirm preclinical data and support the potential for these compounds as targets for therapeutic strategies in disorders involving endothelial dysfunction.
