#1
Zahra M Clayborne, Gerald F Giesbrecht, Rhonda C Bell, Lianne M Tomfohr-Madsen
Lower neighbourhood-level socioeconomic status (SES) has been repeatedly associated with an increased risk of adverse birth outcomes, even after controlling for individual-level SES. Few studies have empirically assessed potential mechanisms underlying the associations. The objectives of this study were to (1) examine relations between neighbourhood SES and birth outcomes, and (2) explore if maternal weight variables mediated these relations. Data came from a provincial prospective pregnancy cohort study in Canada...

OBJECTIVE: The aim of this systematic review and meta-analyses was to comprehensively describe the normotensive pattern of cardiac remodelling during human singleton pregnancies and compared to that during hypertensive complicated pregnancies. METHODS: We performed a meta-analysis of the current literature on cardiac remodelling during normotensive and complicated pregnancies. Literature was retrieved from PubMed (NCBI) and Embase (Ovid) databases. Included studies needed to report a reference measurement (matched non-pregnant control group, pre-pregnancy, or post-partum) and measurements during a predetermined gestational interval...

Objectives Preconception care aims to provide care to reproductive aged individuals in order to improve pregnancy and birth outcomes. Given that preconception care is a public health priority, it is important to evaluate the evolution of this health paradigm and the promotion of preconception messages that are obtained by the public. We identified online preconception health messages, which were critically assessed through a women's health perspective. Methods We searched for "preconception care" on three major search engines...

BACKGROUND: Gestational weight gain is often characterized by the total amount of weight gained during pregnancy, however, the pattern of gain may be an important determinant of health outcomes. The SITAR (Super Imposition by Translation And Rotation) model has been used to describe childhood growth trajectories and has appeal because of the biological interpretability of its parameters. The objective of this study was to determine the feasibility of applying this model to gestational weight gain trajectories...

BACKGROUND: Despite the widely recognized association between the severity of early preterm birth (ePTB) and its related severe diseases, little is known about the potential risk factors of ePTB and the sub-population with high risk of ePTB. Moreover, motivated by a future confirmatory clinical trial to identify whether supplementing pregnant women with docosahexaenoic acid (DHA) has a different effect on the risk subgroup population or not in terms of ePTB prevalence, this study aims to identify potential risk subgroups and risk factors for ePTB, defined as babies born less than 34 weeks of gestation...

PURPOSE: Body size, from birth throughout adulthood, is associated with breast cancer risk, but few studies have investigated early-life body size and benign breast disease (BBD), a well-established breast cancer risk factor. We consider whether prenatal factors and size at birth, 10, 18 year, and intervening growth, are related to BBD risk. METHODS: The Growing Up Today Study includes 9032 females who completed questionnaires annually from 1996 to 2001, then 2003, 2005, 2007, 2010, and 2013...

BACKGROUND: Few studies have examined maternal modifiers of temperature and adverse birth outcomes because of lack of data. We assessed the relationship between apparent temperature, preterm delivery (PTD) and maternal demographics, medical and mental health conditions, and behaviors. METHODS: A time-stratified case-crossover analysis was conducted using 14,466 women who had a PTD (20 to less than 37 gestational weeks) from 1995 to 2009 using medical records from a large health maintenance organization in Northern California...

Studies have suggested an association between maternal obesity pre-pregnancy and gestational diabetes (GDM) with impaired offspring neurodevelopment, but it is not clear if these associations are explained by shared familiar characteristics. We aimed to assess the associations of maternal and paternal obesity, maternal glucose intolerance in early pregnancy and GDM, with offspring neurodevelopment at 4 years of age. We included 772 mother-child pairs from the "Rhea" Mother-Child cohort in Crete, Greece. Data on maternal/paternal body mass index (BMI) and maternal fasting serum samples for glucose and insulin measurements were collected at 12 weeks of gestation...

Gestational diabetes mellitus (GDM), defined as any degree of glucose intolerance with onset or first recognition during pregnancy, is characterized by underlying maternal defects in the β-cell response to insulin during pregnancy. Women with a previous history of GDM have a greater than 7-fold higher risk of developing postpartum diabetes compared with women without GDM. Various risk factors for postpartum diabetes have been identified, including maternal age, glucose levels in pregnancy, family history of diabetes, pre-pregnancy and postpartum body mass index, dietary patterns, physical activity, and breastfeeding...

OBJECTIVES: Evidence suggests a beneficial effect of vitamin D on perinatal health; however, low vitamin D status is prevalent in pregnant women and neonates. The objective was to determine factors that are associated with vitamin D status of mothers in early pregnancy and neonates. METHODS: The study comprised 1,635 pregnant women from Quebec City and Halifax, Canada, 2002-2010. Vitamin D status was based on the concentration of 25-hydroxy-vitamin D [25(OH)D] determined with a chemiluminescence immunoassay in maternal sera collected at a median of 15 weeks' gestation and in neonatal cord sera at delivery...

Effects of pre-gestational physical activity on the later development of embryos generated in vitro were evaluated. Kunming mice were divided into two groups, namely exercised and unexercised, with the former undergoing physical training on a motor-driven leveled treadmill over a period of 4weeks (5days/week and 60min/day). After that, following superovulation, collection of oocytes from both groups was performed for in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT). Notably and specifically, natural mating between the unexercised mice was also done for in vivo fertilization (IVIF)...

INTRODUCTION: Obesity is a major clinical problem in obstetrics being associated with adverse pregnancy outcomes and fetal programming. Brain derived neurotrophic factor (BDNF), a validated miR-210 target, is necessary for placental development, fetal growth, glucose metabolism, and energy homeostasis. Plasma BDNF levels are reduced in obese individuals; however, placental BDNF has yet to be studied in the context of maternal obesity. In this study, we investigated the effect of maternal obesity and sexual dimorphism on placental BDNF signaling...

A substantive obstacle to experimentally studying cigarette smoking and use of other tobacco products in pregnant women is the risk of adverse effects on mother and fetus from experimenter administration of the product of interest. The purpose of this study is to investigate bypassing that obstacle by using behavioral economic simulation tasks. In the present study we used the Cigarette Purchase Task (CPT) to simulate changes in demand for hypothetical cigarettes as a function of varying cigarette prices. Participants were 95 pregnant women who completed the CPT prior to participation in a smoking-cessation trial...
