A Natural History of Genetic and Environmental Predictors of Pubertal Timing Among Youth With Obesity

Background: Obesity affects 1 in 5 children in the United States. Childhood obesity often persists into adolescence and adulthood. It can also raise the risk of sleep apnea, fatty liver disease, and fluid buildup in the brain and lead to early-onset puberty. This natural history study will explore how factors such as genes, hormones, diet, and chemical exposures affect puberty in children with obesity. Objective: To learn which factors predict the early start of puberty in children with obesity vs those of normal weight. Eligibility: Children aged 5 to 7 years with obesity or of normal weight. Design: Participants will have clinic visits every 6 months until they reach age 12. Each clinic visit will include these tests and procedures: A physical exam. Collection of blood, urine, and saliva samples. Some samples will be used for genetic tests. Questions about medical history and medications and supplements. A questionnaire about their physical activity over the previous week. A silicone wrist band. Participants will wear a soft wristband for a week prior to each visit. It will tell researchers what chemicals the children were exposed to during that time. Breast ultrasound, for girls. A gel will be applied, and a wand will be pressed against the skin. The wand uses sound waves to see the tissue inside the breast. DXA whole body scan. Once a year, participants will have a DXA (dual energy X-ray absorptiometry) scan. This scan measures the amount of bone, muscle, and fat in the body. Optional food diary. Parents may record everything the participant eats for two 24-hour periods ...

Evaluation of the Clinical Spectrum of Diabetes and Obesity in Youth and Adults

Background: Diabetes and obesity are chronic diseases. They can affect blood flow and how the body processes nutrients, and complications over time can lead to early death. Diabetes can affect children as well as adults, but the disease seems to be more severe and to progress faster when it appears in younger people. Researchers want to understand more about how diabetes and obesity develop and change over time. Objective: To collect data and samples regularly from people with obesity and diabetes. Eligibility: People aged 8 to 65 years. They must be overweight or obese; or have high blood sugar; or have problems with how their body uses food for energy. Design: Participants will have additional procedures during routine care visits at the NIH clinic. Data collected for the study will include the following: Information from the participant s medical chart will be kept for research. Questionnaires will ask about participant s eating habits, feelings, sleep, and substance use. They will take 30 to 60 minutes. Care providers will address any issues revealed in these surveys. Blood, saliva, urine, and stool samples will be collected. Samples may be used for genetic tests. Data and samples will be kept for future research. Participants may remain in the study up to 30 years.

Trial of the Combination of Alpha-Lipoic Acid and Mirabegron in Women and in Men With Obesity

Background: Obesity and related illnesses cause at least 2.8 million deaths each year worldwide. Few treatments exist for obesity that are safe and widely available. A study drug (mirabegron \[MG\]) combined with a supplement (alpha-lipoic acid \[ALA\]) may help. Objective: To learn how MG and ALA can help the body process food. Eligibility: People aged 18 to 65 years with a body mass index between 30 and 45 kg/m2. Design: Participants will be screened. They will have a physical exam. They will have blood and urine tests and a test of their heart function. They will speak with a dietician. The study has two phases. Each phase begins with a 2-day stay in the clinic; then the participant will take the study drugs at home for about 4 weeks, followed by another 2-day stay in the clinic. They will also have outpatient visits about 2 weeks after each clinic stay. During the clinic stays, participants will undergo many tests: They will have a plastic tube (catheter) inserted into a vein in each arm. These will be used to draw blood and to infuse glucose (sugar) and insulin. They will have imaging scans. They will have a clear hard plastic shield placed over their head to measure oxygen and carbon dioxide as they breathe. Participants will take the study drugs at home. Both MG and ALA are taken by mouth with water. During one phase, participants will take MG plus a placebo. A placebo looks like the study drug but doesn t contain medicine....

Treating Binge Eating and Obesity Digitally in Women

More than 30% of Black women with obesity binge eat. Binge eating may increase the risk for the development of metabolic syndrome and binge-eating-disorder (BED), which is associated with severe obesity. Though several effective treatments for binge eating exist, Black women have not fared well. Not only has their inclusion in treatment trials been limited, but when participating, they are more likely to drop out, and/or lose less weight, compared to their White counterparts. Furthermore, treatment for binge eating is often not available in primary care and community-based settings places where Black women are more likely to receive treatment for their eating and weight-related concerns. Currently, there is scant intervention research to treat binge eating in Black women. With the highest rates of obesity (57%) nationally, Black women are in need of culturally-relevant treatments for binge eating and weight gain prevention. Given the established relationship between frequent binge eating and subsequent weight gain, addressing binge eating among Black women with obesity is imperative.

Variability In Mixed Meal Tests: Fixed Versus Adjusted to Energy Needs Caloric Dose

Background: Researchers use mixed meal tolerance tests (MMTTs) to look at how people s bodies respond to eating a meal. However, researchers do not agree on how to decide the number of calories to give in each meal. Some use fixed meals, which are the same size for everyone, and some use adjusted meals, based on the size of the person s body. Researchers want to know which MMTT is best to use for future research. Objective: To learn how fixed vs adjusted meals affect blood glucose levels in healthy people. Eligibility: Healthy people aged 18 years or older. Design: Participants will have 3 or 4 clinic visits of up to 8 hours in 8 weeks. Participants will have baseline tests: Their height, weight, and waist size will be measured. They will have an oral glucose tolerance test: A needle attached to a tube (IV) will be inserted into a vein in the arm. They will have a sugary drink. Blood samples will be taken from the tube at intervals up to 3 hours after the drink. They will have a body scan. Participants will have 2 MMTT visits. One will include a fixed meal and one will include an adjusted meal. They will have tests at both visits: Resting metabolic rate: A clear hood will be placed over the participant s head while they rest for 20 minutes. This will measure the oxygen they breathe in and out. MMTT. Participants will have 5 minutes to drink a liquid meal. Blood samples will be taken at intervals for the next 4 hours....

Early Tracking of Childhood Health Determinants (ETCHED) Study

Background: Children s weight has increased sharply in recent years. This may put them at higher risk for health problems. High blood glucose in a pregnant mother and too much weight gain during pregnancy also may have long-term effects on the child s health. Children who become overweight or obese during childhood tend to remain so as adults. Researchers want to study many risk factors during and after pregnancy, and how these affect a child s development. They will also follow the mother s health and well-being after pregnancy. Objectives: To learn how a pregnant mother s environment, lifestyle, and health conditions may affect her child s growth and development from birth until adulthood. Eligibility: American Indian/Alaska Native (AI/AN) or Hispanic adult pregnant women and their offspring. Design: Mothers will have 3 visits during pregnancy. In the child s first year, mothers will have 2 visits and their child will have 4. Children will have 2 visits in their second year and 1 each year until they turn 18. Mothers will have a visit 2 years after birth and 4-5 years later. Both the mother and child s medical records will be reviewed. They will have physical exams and give blood and stool samples. Mothers may give cord blood and placenta samples. They will give breastmilk and urine samples. They will fill out questionnaires. They will have an ultrasound. They may get an activity monitor. Mother and child will be followed until the child s 18th birthday.

Heart Health Study in Washington D.C. to Develop a Community-Based Behavioral Weight Loss Intervention

Background: \- Past studies suggest that the best way to improve heart health in the Black community is through community-based programs. Researchers will partner with DC community leaders. They will collect information about the health and health needs of people in mostly Black churches in DC. They will study things that affect heart health, like diabetes, blood pressure, cholesterol, and weight. They will also study how technology can keep track of activities and health. The information will show the health needs of church-based communities or faith-based organizations. Objectives: \- The primary objective of this study is to estimate the percentage of the population that meet ideal, intermediate, and poor criteria for each of the cardiovascular health factors (BMI, physical activity, dietary intake, blood pressure, total cholesterol, fasting plasma glucose, and cigarette smoking) in churches or faith-based organizations in the DMV area. This data will inform the design and implementation of a behavioral weight-loss intervention within the faith-based community immediately following this study. The secondary objectives are to: 1) evaluate usage of handheld devices for objectively measuring physical activity and dietary intake; 2) evaluate usage of web-based technology for monitoring cardiovascular health markers, including dietary intake; 3) examine referral methods for untreated hypertension, diabetes, and hypercholesterolemia; 4) compare lifestyle behaviors across levels of psychosocial factors, cultural norms, and neighborhood environment factors; and 5) formalize a community advisory board involved in the implementation of the health screening and needs assessment program and a future behavioral weight-loss intervention. Eligibility: \- Adults ages 19 to 85 who attend one of the study churches. Design: * Participants will visit their church for a 4-hour health exam. They will have their blood pressure and body measurements taken. They will have a drop of blood taken from their finger with a small needle. This blood will be tested for blood sugar and cholesterol. Participants will be given the results of these tests. * Participants will answer questions about their health. * All participants will be given an activity monitor to wear for 1 month. The activity monitor is worn around the wrist. Some participants will also receive an activity monitor that is worn around the waist. Participants will be given instructions on how to wear the activity monitors and follow the results on a website. * At the end of 1 month, participants will return one device (they can keep the other). They may receive a gift card for completing the study.

Diabetes and Heart Disease Risk in Blacks

It is unknown if obesity contributes to the development of heart disease in African American men and women. This study was created to determine whether there is a relationship between sex and body size and the incidence of heart disease in African American men and women. Researchers will attempt to associate obesity with the presence of heart disease risk factors. Risk factors that will be studied include; total body fat, body fat distribution, fat content of the blood (triglyceride concentration, low density lipoproteins \[LDL\], and high density lipoproteins \[HDL\]), how fast fat is removed from the blood, and how well insulin works in the body. Scientific studies have shown that obesity and increased levels of fat content in the blood are important risk factors for heart disease in Caucasian women. However, similar studies in African American women have failed to show the same correlation. In fact, it appears that African American women in all three body weight groupings, nonobese, overweight, and obese experience high death rates due to heart disease. In addition, prior research has shown that obese African American men tend to have elevated levels of fat in the blood while African American women have normal blood fat levels. Therefore, if high levels of triglycerides (fat found in the blood) are not seen in non-diabetic obese African American women, it cannot be considered a risk factor in this population. This suggests that studies conducted on Caucasian women may not provide insight into heart disease risk factors in African American women. The study will take 2000 healthy non-diabetic African American men and women (ages 18-70) and body mass index 3 subgroups; nonobese, overweight and obese. Diabetes undeniably increases the risk of heart disease. Therefore patients suffering from diabetes will not be included in the study. Candidates for the study will undergo a series of tests and examinations over 2 outpatient visits. Subjects will have body fat analyses, resting energy expenditure measurements, an EKG (electrocardiogram), and specific blood tests. Researchers believe this study will provide significant insight into the causes of obesity and heart disease in African Americans....

A Study to Test Whether BI 3034701 Helps People to Lose Weight Who Live With Obesity or Overweight

This study is open to adults between 18 and 74 years of age and who have a body mass index (BMI) of 30 kg/m2 or more, or a BMI of 27 kg/m2 or more and at least 1 health problem related to their weight. People who have previously not managed to lose weight by changing their diet can participate. People with type 2 diabetes cannot take part in this study. The purpose of this study is to find out whether a medicine called BI 3034701 helps people living with obesity or overweight to lose weight. This study has 7 groups of participants. Groups 1 to 6 get different doses of BI 3034701; Group 7 gets placebo. Placebo looks like BI 3034701 but does not contain any medicine. Every participant has more than an 80% chance of getting BI 3034701. Participants receive 2 injections of BI 3034701 or placebo under their skin for 42 weeks. In addition to the study medicine, all participants receive counselling to make changes to their diet and to exercise regularly. Participants are in the study for about 10 months. During this time, they visit the study site 15 times. The study doctors regularly measure the participants' body weight and take necessary laboratory tests. Participants also answer questions about their well-being and note their food intake and physical activity in diaries. The results will be compared between groups of participants to see whether the treatment works. The study doctors also regularly check participants' health and take note of any unwanted effects.

Motivating Increases in Physical Activity for Prevention of Weight Regain After Metabolic Bariatric Surgery

The goal of this clinical trial is to learn if a psychological intervention can increase regular physical activity to help prevent weight regain after metabolic bariatric surgery in adults. The main questions it aims to answer are: 1. Does the psychological intervention increase physical activity? 2. Does the psychological intervention prevent weight regain? 3. Does the psychological intervention increase internal motivation for physical activity and acceptance of the discomfort that can come with physical activity? Researchers will compare the psychological intervention to an educational intervention to see if the psychological intervention works to increase physical activity and prevent weight regain after metabolic bariatric surgery. Participants will: * Complete 12 months of either the psychological or educational intervention. This includes attending online workshops with a small group of participants, completing brief homework assignments, and having individual telephone calls with a counselor. * Wear a device to measure physical activity, use an electronic scale to measure body weight, and complete questionnaires at home on five separate occasions over an 18-month period

The CWMM establishes entry criteria for newly enrolled participants across the master and the ISAs. The ISAs may start independently of other ISAs as interventions become available for clinical testing. The results for the CWMM screening record will be reported when all the ISA's complete.
