Filter by:This two-arm, double-blind randomized clinical trial will recruit 208 generally healthy, low-risk pregnant individuals aged 19-42 years living in Vancouver, Canada. Participants will be randomized to receive one of two forms of iron (ferrous fumarate or ferrous bisglycinate) in addition to a prenatal multivitamin (without iron) daily during their pregnancy until delivery, with optional continuation until ~4 weeks postpartum for breastmilk sample collection. Blood samples will be taken at baseline and again at ~37 weeks gestation to assess how different forms of iron impact body iron stores. Rectal swabs will also be taken at baseline and ~37 weeks gestation to detect presence of harmful bacteria in the gut and quantify their abundance. This research will inform more specific guidelines for optimal iron supplementation practices for the prevention and treatment of iron deficiency for both mother and baby.
Indigenous American pregnancies in the Midwest have disproportionally high rates of adverse outcomes, however little research has been done on how historical trauma and stress may impact these adverse outcomes. This project gathers data from pregnant Indigenous American women on their experiences with historical trauma, stress, and birth outcomes, as well as physiological data of how they respond to stress, in order to better understand the associations between these factors and the biological mechanisms underlying them. Understanding the mechanisms by which both historical and proximal stress "get under the skin" and influence pregnancy health and perinatal outcomes, will afford new targets of intervention to help reduce these IA health disparities.
The aim of this randomised controlled trial is to compare the effects of an antenatal education class including a breathing and relaxation technique on self-efficacy compared to a standard antenatal education class without a focus on breathing and relaxation techniques.
The PLANET Study aims to determine the impact of microplastics on intestinal inflammation and gut microbiome in order to understand the role of this pollutant on the risk of developing inflammatory bowel disease (IBD) as well as other diseases. With this information, the researchers hope to characterize better the role of environmental pollutants on IBD and develop novel strategies towards prevention.
Iron requirements increase significantly during pregnancy. Current recommendations for iron intake in pregnant and lactating women (PLW) are mainly based on factorial estimates and extrapolated from non-PLW. High-quality quantitative data on iron requirements in PLW are lacking, particularly in Sub- Saharan Africa where anaemia and infections are common. The primary objective of this study is to use the stable iron isotope technique to determine iron requirements and assess iron absorption and losses in PLW living in Kenya. In this prospective observational study, we will enrol pregnant women in the first trimester (n = 250) from a previous study cohort (n=1000) who participated in an iron absorption study at least 12 months ago and received the stable iron (Fe) isotope 57Fe. This 57Fe has now distributed and equilibrated throughout the women's body iron. Once enrolled in the present study, following Kenyan guidelines, women will receive standard prenatal care, including routine daily iron and folate supplementation. We will collect venous blood samples in each trimester and at delivery, and during the first 6 months of lactation in the mothers and infants (heel prick samples). To directly assess dietary iron absorption, in a randomly selected subset of women (n=35), oral and intravenous stable iron isotope tracers (54Fe, 58Fe) will be administered in the 2nd and 3rd trimesters.
The P3OPPY Project is one of five projects within the American Heart Association P3 EQUATE Network. The overarching goal of the P3 EQUATE American Heart Association Health Equity Research Network (HERN) is to promote equity in Maternal and Infant Health outcomes by identifying innovative and cost-effective strategies to enhance access to quality health information, care, and experiences during pregnancy, postnatal and postpartum/preconception periods, particularly for Black and under-served populations. Collectively, the investigators will collaborate with pregnant and postpartum individuals and their families, hospitals, and communities to discover ways to reduce racism and social problems that contribute to poor health outcomes.
In recent decades, obesity has become a prevalent issue in Portugal, with 38.6% and 13.8% of the population being overweight or obese, respectively. Obese pregnant women have a higher rate of obstetric complications, including hypertensive complications, gestational diabetes and fetal macrosomia, leading to increased induction of labor (IOL) and cesarean section (CS) rates. To determine the effect of increasing oral misoprostol dose on CS rate in obese pregnant women undergoing IOL, a randomized controlled trial with a sample size of 114 cases in each group was calculated to detect a 15% difference in CS rate. The primary objective is to determine the effect of increasing oral misoprostol dose, with secondary goals being to compare successful IOL rates and their relationship with oral misoprostol dose, as well as to evaluate tolerability and side effects in relation to different doses of oral misoprostol.
The goal of this clinical trial is to see if the enhanced HMZ 2.0 intervention with new control system/digital platform to regulate gestational weight gain (GWG) and impact maternal-infant outcomes while collecting implementation data works and can be given to other pregnant women in various settings. The question this study aims to answer are: 1. Does the new intervention manage GWG? 2. Does the new intervention have any influence on sleep and eating behaviors and infant outcomes. 3. Does the new platform and other data collected help inform how well the research and information can be used in health care settings? 144 pregnant women with overweight/obesity will be randomized to either the HMZ 2.0 intervention or attention control groups from ~8-36 weeks gestation. All participants will be asked to: 1. Weight themselves and wear an activity monitor each day over the study. 2. Complete online surveys at either a weekly or monthly level about their thoughts, attitudes, and behaviors on GWG, physical activity, eating behaviors, sleep, their anxiety, depression, and stress. 3. Attend weekly sessions with a registered dietician. The weekly sessions will differ based on intervention group. The HMZ 2.0 intervention group will receive education, create and follow goal-setting and action plans, self-monitor their behaviors, and receive feature evidence and fetal growth facts. Education, goals, and self-monitoring will focus on GWG, physical activity, eating behaviors, sleep, self-regulating behaviors and emotions, and preparing for labor/delivery and postpartum. The attention control group will receive weekly sessions on preparing for labor/delivery and benefits of behavioral pain management strategies (e.g., mindfulness-based relaxation, imagery, music, massage, deep-breathing) to help with pain after childbirth without medicine.
During pregnancy, gestational diabetes increases the risk of complications and adverse outcomes for mother and child, however about 50% of gestational diabetes cases are diagnosed without a known risk factor present. This project uses both a large sample retrospective study, and a prospective study to help us understand the mechanisms by which mental health and stress impact glucose metabolization during pregnancy and delineate their contribution to gestational diabetes and racial disparities. The investigators expect, to improve the ability to identify women at risk, and advance options for preventative care and treatment, decreasing the impact of gestational diabetes and related complications.
The goal of this randomized clinical trial is to evaluate the effectiveness of SmartMom, a text messaging-based mobile health program for prenatal education. The main questions are to determine if healthy pregnant people receiving SmartMom messages that promote health behaviours in pregnancy versus messages that don't provoke behaviour change have improvement in: 1. knowledge about healthy pregnancy and birth 2. standardized measures of depression, anxiety, and fear of childbirth 3. adoption of positive health behaviours in pregnancy 4. maternal, fetal, and newborn outcomes Participants in the intervention group will receive three evidence-based text messages per week, plus optional supplemental messages on topics relevant to them, throughout pregnancy. The control group will receive general interest messages on pregnancy-related topics that are not promoting behaviour change.
