Worries, beliefs and factors influencing perinatal Covid-19 vaccination: A cross-sectional survey of preconception, pregnant and lactating individuals
In this Canadian perinatal population, approximately 42% reported COVID-19 vaccination. Among unvaccinated individuals, willingness to receive vaccination was high (73%). Factors enhancing vaccine willingness included discussions with healthcare providers and believing the vaccine was effective. Concerns regarding vaccine safety, particularly with respect to fetal/child development, were the greatest barriers to vaccine uptake
Giving Birth in the Early Phases of the Covid-19 Pandemic: The Patient Experience
The determinants of maternal homocysteine in pregnancy: Findings from the Ottawa and Kingston Birth Cohort
Objective: Observational studies have linked elevated homocysteine to vascular conditions. Folate intake has been associated with lower homocysteine concentration, although randomised controlled trials of folic acid supplementation to decrease the incidence of vascular conditions have been inconclusive. We investigated determinants of maternal homocysteine during pregnancy, particularly in a folic acid-fortified population. Design: Data were from…
Serum and red-blood-cell folate demonstrate differential associations with BMI in pregnant women
Objective To examine the association between BMI and folate concentrations in serum and red blood cells (RBC) in pregnant women. Design A cross-sectional comparison of folate concentrations in serum and RBC sampled simultaneously from the same individual. Setting The Ottawa Hospital and Kingston General Hospital, Ontario, Canada. Subjects Pregnant women recruited between 12 and 20 weeks of gestation. Results A total of 869 pregnant women recruite…
Chronic Perinatal Pain as a Risk Factor for Postpartum Depression Symptoms in Canadian Women
H1N1 Influenza Vaccination During Pregnancy and Fetal and Neonatal Outcomes
Objectives. We evaluated the relationship between maternal H1N1 vaccination and fetal and neonatal outcomes among singleton births during the 2009–2010 H1N1 pandemic. Methods. We used a population-based perinatal database in Ontario, Canada, to examine preterm birth (PTB), small-for-gestational-age (SGA) births, 5-minute Apgar score below 7, and fetal death via multivariable regression. We compared outcomes between women who did and did not recei…
