Benefits of Resistance Training During Pregnancy for Maternal and Fetal Health: A Brief Overview.

Research demonstrates resistance training is not only safe but also beneficial for pregnant women. However, exercise recommendations for pregnant women still minimize the importance of resistance exercise and provide minimal guidance. With a large increase in strength-focused sports among women, it is critical to re-evaluate the risk/benefit ratio of these exercises and ensure the latest recommendations reflect the latest clinical research.

Modifiable Maternal Factors and Their Relationship to Postpartum Depression.

The purpose of the study was to examine how modifiable maternal factors (body mass index (BMI), household income, fatigue, sleep, breastfeeding status, diet, and physical activity) relate to postpartum depression (PPD) at 6 and 12 months postpartum. Participants (n = 26) participated in two study visits (6 and 12 months postpartum) where vitals, weight, body composition (skinfold anthropometrics), and physical activity levels (Actigraph GTX9 accelerometer) were assessed. Validated instruments (BRUMS-32, Subjective Exercise Experience Scale, Pittsburg Sleep Quality index, NIH breastfeeding survey, NIH Dietary History Questionnaire, and Edinburg Postnatal Depression Scale) assessed lifestyle and demographic factors of interest.

Effect of excessive gestational weight gain on insulin sensitivity and insulin kinetics in women with overweight/obesity.

Objective: Obesity increases the risk for pregnancy complications and maternal hyperglycemia. The Institute of Medicine developed guidelines for gestational weight gain (GWG) targets for women with overweight/obesity, but it is unclear whether exceeding these targets has adverse effects on maternal glucose metabolism.

Methods: Insulin sensitivity (assessed using the Matsuda Insulin Sensitivity Index), β-cell function (assessed as insulin secretion rate in relation to plasma glucose), and plasma insulin clearance rate were evaluated using a frequently sampled oral glucose tolerance test at 15 and 35 weeks of gestation in 184 socioeconomically disadvantaged African American women with overweight/obesity.

Physical Activity during Pregnancy and Newborn Body Composition: A Systematic Review.

The current literature demonstrates that not only is exercise during pregnancy safe, but it has substantial maternal and infant benefits and appears to influence infant growth/size throughout pregnancy and at birth. However, many existing studies have investigated only the effects of prenatal exercise on birth weight. The purpose of this review was to determine the impact or association of maternal physical activity during pregnancy on neonatal body composition assessed between birth and two weeks of age.

To Be Active or to Stop? A Cross-Sectional Retrospective Study Exploring Provider Advice and Patient Fears Surrounding Physical Activity in Pregnancies Complicated by Fetal Growth Restriction.

Exercise guidance for women with pregnancies complicated by fetal growth restriction (FGR) is vague, despite the fact that physical activity during pregnancy improves placental development, placental blood flow, and encourages healthy fetal growth. The goal of this study is to test the hypothesis that women with pregnancies complicated by FGR are fearful of physical activity and are being given unclear or limited advice from healthcare providers. Participants (N = 78) (women who delivered an infant diagnosed with FGR within the past 5 years) took an electronic survey including demographic information, pregnancy information, provider advice recall, and other health-related information relevant to growth-restricted pregnancies.

A Web-Based Educational Intervention to Increase Perinatal Nurse and Pre-Licensure Student Knowledge and Self-Efficacy in Providing Postpartum Depression Care.

Perinatal nurses and pre-licensure nursing students may lack knowledge of postpartum depression and appropriate interventions. Nurses and students may also have decreased self-efficacy in assessing for postpartum depression and providing education on this potential complication to new mothers. This project examined the use of a web-based educational module to increase perinatal nurses' and pre-licensure nursing students' knowledge of postpartum depression and postpartum depression interventions.

Physical Activity during Pregnancy may Mitigate Adverse Outcomes Resulting from COVID-19 and Distancing Regulations: Perspectives of Prenatal Healthcare Providers in the Southern Region of the United States.

Prenatal physical activity (PA) may mitigate adverse outcomes that have increased as a result of the coronavirus pandemic, including poor maternal mental health. This study explored the perspectives of prenatal healthcare providers (PHCP) on maternal PA during the pandemic and identified resources providers would like to have to inform clinical discussions and prescription of PA. Semi-structured interviews were completed with PHCPs following a qualitative description approach.

Elevated lipid oxidation is associated with exceeding gestational weight gain recommendations and increased neonatal anthropometrics: a cross-sectional analysis.

Background: Deviations from gestational weight gain (GWG) recommendations are associated with unfavorable maternal and neonatal outcomes. There is a need to understand how maternal substrate metabolism, independent of weight status, may contribute to GWG and neonatal outcomes. The purpose of this study was to explore the potential link between maternal lipid oxidation rate, GWG, and neonatal anthropometric outcomes.

Postpartum Metabolism: How Does It Change from Pregnancy and What are the Potential Implications?

Background: Metabolic dysfunction after pregnancy may have serious consequences for a new mother. The purpose of the study was to characterize basic changes that occur in metabolic profiles from late pregnancy through 4-6 months postpartum. A secondary purpose was to determine metabolic factors that may be contributing to postpartum weight retention.

An Assessment of Mobile Applications Designed to Address Physical Activity During Pregnancy and Postpartum.

Only 15% of women meet physical activity guidelines during and after pregnancy despite the well-established positive impacts on both the mother and the neonate. There is a clear lack of guidance on this topic, and mobile health interventions are a promising direction for future interventions to facilitate a necessary increase in physical activity during pregnancy and postpartum. The purpose of the study was to objectively assess the quality and perceived impact of existing free mobile apps that are designed to cover physical activity during and after pregnancy.

Obstetric Patients and Healthcare Providers Perspectives to Inform Mobile App Design for Physical Activity and Weight Control During Pregnancy and Postpartum in a Rural Setting.

Background: Mobile health technology offers the opportunity for women to engage with physical activity promotion programs without many of the barriers commonly associated with exercise during and after pregnancy (eg, childcare concerns, rigid schedules, fear of doing harm to fetus or self, access to fitness facilities, uncomfortable with body in front of others) which may be particularly useful in under-resourced rural environments. We conducted the first known study on perspectives of pregnant women, postpartum women, and obstetric healthcare providers in a rural setting on needs related to the development of a mobile app designed to increase physical activity during pregnancy and postpartum.

Methods: Focus groups and in-depth face-to-face personal interviews were conducted with 14 pregnant women, 13 postpartum women, and 11 healthcare providers in a rural community.

Metabolic flexibility during late pregnancy is associated with neonatal adiposity.

The aim of this study was to determine the relationships between maternal metabolic flexibility during pregnancy and neonatal health outcomes. Percent change in lipid oxidation (before and after a high-fat meal) was calculated as the measure of "metabolic flexibility". Neonatal adiposity was assessed within 48 h of delivery by skinfold anthropometry.

Metabolic Flexibility and Weight Status May Contribute to Inter-Individual Changes in Breastmilk Lipid Content in Response to an Acute Bout of Exercise: Preliminary Findings from a Pilot Study.

The purposes of this pilot study were to describe changes in breastmilk lipid content in response to an acute bout of moderate intensity exercise and to explore maternal metabolic health factors, including metabolic flexibility, which may impact this change. A cross-sectional, observational, pilot study design was performed in 14 women between 4 and 6 months postpartum. Whole body fasting lipid oxidation was assessed, a standardized high-fat breakfast was consumed, and lipid oxidation was again measured 120-minutes post-meal.

Prenatal Yoga and Mental Health During the COVID-19 Pandemic: A Randomized-Control Trial.

Studies have demonstrated that new and expectant mothers experience increased levels of stress and anxiety during the COVID-19 pandemic. Though prenatal yoga is an effective mode of improving mental health during pregnancy, no research has evaluated its effect on mental health during times of extreme stress, such as a global pandemic. The purpose of this study was to determine the influence of a single session and a 10-week prenatal yoga intervention on the mental health of pregnant women during the COVID-19 pandemic.

High-fat meal increases peripheral blood mononuclear cell pro-inflammatory cytokine expression in African-American women.

African-American (AA) women have elevated predominance of inflammatory diseases concurrent with local inflammation resulting in compromised metabolic function. The purpose of the study was 2-fold: 1) to examine the gene and protein expression of pro- and anti-inflammatory cytokine secretion by peripheral blood mononuclear cells (PBMC) obtained from AA and Caucasian-American (CA) women in response to an acute high-fat meal; and 2) to explore the influence of race (AA vs. CA) on PBMC reactivity.

Patient and Provider Communication Regarding Exercise during Pregnancy in a Rural Setting.

Women in rural settings are at increased risk for adverse pregnancy outcomes. One potential way to improve pregnancy outcomes in rural settings is through physical activity promotion. However, given the disparities in prenatal care, women in rural areas may not receive information from their health care provider regarding physical activity during pregnancy.

Effect of Evidence-Based Materials and Access to Local Resources on Physical Activity Levels, Beliefs, and Motivation During Pregnancy in a Rural Setting.

Background: The purpose of this study was to determine the impact of evidence-based educational materials and access to local resources on physical activity (PA) levels, beliefs, and motivation (including self-efficacy) regarding PA during pregnancy in a rural setting.

Methods: Information on PA levels (step counts, Pregnancy Physical Activity Questionnaire) and beliefs and motivation regarding PA (main surveys: Exercise Beliefs Questionnaire, Protection Motivation Theory and Health Action Process Approach) were collected between 8 and 16 weeks gestation. Women from a rural community were randomly assigned to the PA group (PAG, n = 38) or control group (n = 32).

Exploring Beliefs About Exercise Among Pregnant Women in Rural Communities.

Introduction: Women who are pregnant in rural communities are disproportionally impacted by obesity and sedentary behavior, and this could be related to having negative beliefs about exercise during pregnancy, leading to inactivity. The purpose of this study was to identify self-reported beliefs about exercise among pregnant women in a rural community.

Methods: Pregnant participants (N = 70) between 8 and 16 weeks' gestation were recruited from an obstetric clinic serving a rural population.
