12 Clinical Trials for Various Conditions
This study is being done to test the feasibility, acceptability, and preliminary efficacy of a meal delivery intervention for managing gestational weight gain among pregnant women with overweight or obesity.
The ClockWork Postpartum Weight Management Pilot Study is an intervention study that will assess the feasibility, acceptability, and initial efficacy of the ClockWork intervention among women with prepregnancy overweight/obesity during the first 4 months postpartum.
Moms Are Worth It is a lifestyle behavior intervention study aims to prevent excessive gestational weight gain in overweight or obese pregnant women through promotion of the stress management, healthy eating, and physical activity. Eligible women will be randomly assigned to a usual care or an intervention plus usual care group. The intervention will last 20 weeks and will be delivered via weekly web and individual health coaching session (10 of them)
The purpose of this study is to learn if consuming a high fiber diet will reduce gestational weight gain and maternal and infant fat accretion.
The purpose of this study is to evaluate the effect of access to nutrition services on pregnancy outcomes in the obese urban population. There are many studies that have shown that obesity has a negative impact on pregnancy. However, currently there are only a few small studies that specifically look at ease of access to nutrition services in an obese urban population and the effect this has on maternal weight gain and pregnancy outcomes. This study will compare two groups of pregnant women with a BMI of 30 or greater. The investigators hypothesize that access to nutritional services will lead to decreased weight gain during pregnancy and improved pregnancy outcomes.
Obesity is a significant health issue in the United States with 30% of the US population considered obese defined as a body mass index above 30 kg/m2. Obesity is associated with long term health complications including diabetes and cardiovascular disorders. During pregnancy, obesity is associated with an increased risk of fetal macrosomia and birth injury, as well as increased risk of gestational diabetes, preeclampsia, cesarean birth, and preterm birth. The intrauterine environment has been purported to influence the early childhood and lifelong risk of obesity and the metabolic syndrome (obesity, hyperlipidemia, and insulin resistance \[IR\]). The Institute of Medicine guidelines for maternal weight gain in pregnancy provide an estimate for population goals, but may be inadequate for individual patient needs. Other factors, such as the degree of maternal IR and resting metabolic rate (RMR) may be more predictive of actual nutritional needs during pregnancy. A better determination of caloric and exercise needs may allow the development of more specific dietary recommendations during pregnancy. Optimal nutrition will result in improved maternal and neonatal outcomes. As the intrauterine environment may have important impacts on neonatal and childhood metabolic and cardiovascular outcomes, creation of a favorable intrauterine environment through optimal maternal nutritional and exercise guidelines may reduce well documented problems such as fetal macrosomia, birth injury, cesarean delivery, and later predisposition toward childhood obesity. The goal of this pilot trial therefore is to correlate maternal resting metabolic rate, dietary characteristics, and insulin resistance levels with fetal birth weight and body composition in an effort to determine which factors are associated with excessive fat mass in the neonate, placing them at increased lifetime risk of obesity. We hypothesize that women with lower resting metabolic rates (RMR) in the first trimester will demonstrate a greater maternal weight gain, when adjusted for caloric intake and activity. It is also hypothesized that for a given RMR, the degree of maternal insulin resistance (IR) predicts birthweight adjusted for a given caloric intake. A third hypothesis is that women with increased insulin resistance (measured by HOMA) will result in neonates with larger birth weights and a greater degree of neonatal fat mass as measure by DEXA scan, adjusted for RMR and diet characteristics.
The purpose of this study is to enable the investigator to conduct proof of concept work related to the feasibility, acceptability, initial efficacy and mechanisms of action (focusing on maternal and infant modifiable factors) for a novel self-management intervention for pregnant women.
The prevalence of maternal overweight and obesity has nearly doubled in the United States since 1976. In 2004-2005, 42% of pregnant women had body mass index (BMI) above 25 versus 23% in 1993. Most American women are overweight/ obese (OW/OB) at conception, especially within certain racial, ethnic, and lower socioeconomic groups leading to increased adverse maternal and birth outcomes. This study will recruit, randomize and test in 300 ethnically diverse OW/OB pregnant women a behavioral intervention aimed at controlling gestational weight gain (GWG) through recommended diet, activity and lifestyle changes that are to be maintained postpartum. Outcomes include anthropometric (height, weight, percent body fat) metabolic (blood pressure, fasting glucose, insulin, HbA1c, lipids and C-reactive protein) and behavioral measures (diet. physical activity, sleep and stress). In addition, babies will be measured for length, weight and percent body fat. The goal is to limit excessive gestational weight gain through improved maternal lifestyle that can be maintained and modelled for the family post partum and beyond.
The MAMAS study is built on the premise that simple recommendations for diet and exercise may not be enough to encourage healthy weight gain during pregnancy. Psychological skills training may be necessary to help women deal with stress and cravings; learn to regulate difficult emotions; increase awareness; and encourage healthy eating and physical activity. The goal of this study is to find out whether a behavioral stress reduction intervention can help women achieve healthy weight gain during pregnancy and reduce stress.
The proposed multicomponent digital health intervention has the potential to significantly impact the trajectory of maternal health in a rural, pregnant, Black adolescent population with the highest risks for cardiometabolic diseases worldwide. The proposed implementation strategy leverages mobile technologies which are ubiquitous across the socioeconomic gradient and proposes to train young adult WIC moms to deliver peer health coaching in a telehealth setting to address social barriers and support behavior change in pregnant, Black adolescent WIC clients in the Mississippi Delta - a rural region where the population is more than two-thirds percent Black and the teen birth rate is the highest in the United States. This is a scalable and sustainable approach to enhance WIC services and improve WIC's impact on population health and cardiometabolic health disparities in Black women.
The goal of this clinical trial is to test an enhanced version of the National Diabetes Prevention Program (NDPP-NextGen) that is tailored to young women in childbearing years. The investigators will recruit 360 women aged 18-39 years with overweight/obesity who are not currently pregnant, but likely to conceive within 24 months. Women will be randomized to NDPP-NextGen or a usual care control group. The NDPP-NextGen group will participate in the adapted NDPP online group class across 12 months, and the control group will get a packet of information about how to be healthy before, during and after pregnancy. The main goals of the study are: 1. to assess effects of NDPP-NextGen on pre-pregnancy blood sugar and early pregnancy BMI 2. to assess effects of NDPP-NextGen on weight gain and behavioral outcomes during pregnancy 3. to explore effects of NDPP-NextGen on infant's percentage of fat tissue at birth All participants will complete up to 4 research visits: baseline, conception, mid-pregnancy, and delivery. These visits will include: 1. Questionnaires about health, diet, activity, smoking, self-confidence, and depression 2. Body size measurements 3. Fasted blood draws Participants will also be asked to weigh themselves weekly using home scales that are connected to the research database. At the delivery visit, investigators will measure the baby's body size and collect a cord blood sample.
This study is being done to assess the feasibility, acceptability, and preliminary impact of a meal delivery intervention designed to improve diet quality and promote appropriate gestational weight gain among predominantly Black and low-income pregnant women with overweight or obesity. This will be done by 1) assessing the feasibility and acceptability of the meal delivery intervention; 2) investigating changes in patient-reported diet quality, barriers to healthy eating, and food security; and 3) exploring the preliminary impact of the meal delivery intervention on gestational weight gain and blood pressure and estimate the effect size of the intervention relative to a de-identified non-randomized control group that will be derived from de-identified hospital records.
