Background: Individuals residing in rural areas and those with low socioeconomic status are typically underrepresented in clinical research. Strategies to recruit more representative populations should be explored. This study aimed to compare screening and consenting proportions in a West Virginia-based pregnancy cohort study of individuals sent a recruitment message via the MyChart patient portal, overall and stratified by rurality and insurance status (proxy for socioeconomic status).

Problem: Postpartum women are largely insufficiently active and therefore, at risk for many adverse health outcomes.

Background: The 2018 Physical Activity Guidelines recommend postpartum women perform moderate-to-vigorous physical activity (MVPA) and muscle strengthening exercise (MSE) to promote overall health and reduce the risk of chronic diseases. Urinary incontinence (UI) is a barrier to physical activity in the general population, but postpartum women have not been represented in previous studies.

The Physical Activity Guidelines for Americans supports sitting less and moving more. Growing evidence suggests that a waking behavior profile with less sedentary behavior and more light-intensity physical activity is associated with more favorable cardiovascular health. Remarkably, little is known about how these behaviors relate to cardiovascular health during pregnancy.

Objective: Urinary incontinence (incontinence) is a common condition among women which may contribute to low moderate-to-vigorous physical activity (MVPA). Thus, women with incontinence may have increased risk for inactivity and related cardiovascular disease (CVD). The objective of this study was to determine the associations of incontinence with MVPA and CVD risk.

Rapid cardiovascular and autonomic adaptations occur during early pregnancy to accommodate augmented cardiac output and placental circulation, with inadequate adaptation associated with hypertensive pregnancy complications. Habitual physical activity (PA) and limiting time in sedentary behavior (SED) may improve pregnancy-related vascular and autonomic function. The objective of this study was to examine the magnitude of the predicted associations between device-measured PA and SED with cardiovascular and autonomic biomarkers including aortic stiffness, blood pressure variability (BPV), and baroreflex sensitivity (BRS) in the first trimester of pregnancy.

Background: Cardiovascular disease (CVD) is the leading cause of death among women in America. Hypertensive disorders of pregnancy (HDP) negatively impact acute and long-term cardiovascular health, with approximately 16% of all pregnancies affected. With CVD 2-4 times more likely after HDP compared to normotensive pregnancies, effective interventions to promote cardiovascular health are imperative.

Background: Individual health behaviors are associated with pregnancy outcomes, but their joint effects are rarely considered. We aimed to examine associations between combinations of first trimester health behaviors and hypertensive disorders of pregnancy (HDP), normotensive adverse pregnancy outcomes (APOs), and blood pressure (BP) 2-7 years after delivery.

Methods: Participants in the nuMoM2b and follow-up Heart Health Study were included.

Background: Physical activity is recommended during pregnancy, and high sedentary behavior and poor sleep may increase the risk of pregnancy complications. Activity patterns and sleep were negatively impacted by the COVID pandemic in many segments of the population, but the impact of the pandemic on pregnant people is understudied. We aimed to compare patterns of physical activity, sedentary time, and sleep during pregnancy between a pre-COVID and a COVID-era cohort.

Article Synopsis
  • The study aimed to translate childhood cardiovascular (CV) risk factors into clinically actionable values that could predict adult CV diseases and type 2 diabetes mellitus (T2DM).
  • It involved a long-term observational study with nearly 39,000 participants, tracking children from ages 3 to 19 over 30 years and analyzing several CV risk factors like BMI, blood pressure, and cholesterol.
  • Findings revealed that the risk for CV events and T2DM starts at levels previously deemed normal, suggesting that earlier intervention may be necessary to prevent adult diseases.

Article Synopsis
  • The study investigated how occupational physical activity (OPA) and sedentary behavior (SB) during pregnancy influence overall physical activity patterns and health outcomes for both mothers and infants.
  • Researchers analyzed data from two cohorts, identifying four distinct groups based on participants' OPA patterns: sitting, part-time mixed, active, and non-working.
  • While significant variations in daily physical activity were observed among the groups, there were no notable differences in adverse pregnancy outcomes or infant health indicators across these groups.

Lifestyle modifications are the first-line treatment recommendation for elevated blood pressure (BP) or stage-1 hypertension (E/S1H) and include resistance exercise training (RET). The purpose of the current study was to examine the effect of a 9-wk RET intervention in line with the current exercise guidelines for individuals with E/S1H on resting peripheral and central BP, vascular endothelial function, central arterial stiffness, autonomic function, and inflammation in middle-aged and older adults (MA/O) with untreated E/S1H. Twenty-six MA/O adults (54 ± 6 yr; 16 females/10 males) with E/S1H engaged in either 9 wk of 3 days/wk RET ( = 13) or a nonexercise control (Con; = 13).

Hypertensive disorders of pregnancy and other adverse pregnancy outcomes (APOs) are associated with an increased risk of future maternal cardiovascular disease. Physical activity during pregnancy reduces the risk of these APOs, yet few meet physical activity guidelines during pregnancy. Little is known about the role of sedentary behavior or sleep in APOs, a critical gap in knowledge given these behaviors comprise the majority of a 24-hour day.
