Clinical Trials

Are you an adult who does not have high blood pressure and is interested in research? This study will investigate how the brain regulates the body’s response to stress and how infection with HIV or pre-hypertension affects regulation. Your heart and brain activity will be measured while you are at rest, during a mentally stressful task, and while you feel angry. The study will also test whether a breathing exercise improves regulation. People with and without HIV and pre-hypertension will be included. To participate in this study, you must be between 21 and 65 years old and not have high blood pressure. This study is located in Miami, Florida.

Do you have overweight or obesity and are not in a weight management program? This study is investigating whether self-weighing, combined with follow-up encouragement, promotes weight loss and use of weight management resources. To participate in this study, you must be between 18 and 70 and overweight or obese and with weight-related comorbidity (hypertension, type II diabetes, pre-diabetes, dyslipidemia, sleep apnea). This study is located in Gainesville, Florida.

Does your child have overweight or obesity? This study is exploring the link between obesity and sleep deprivation in children. Researchers will test whether participants who do not get enough good quality sleep have trouble making healthy food choices. Participants in this study must be 8 to 12 years old and have overweight or obesity. This study takes place in Pittsburgh, Pennsylvania; and Providence, Rhode Island.

Are you an adult with obesity and at high risk of heart and blood vessel disease? This study is testing a new program to help people who have obesity stick to their healthy eating plan. Researchers from this study are developing a program that will predict when participants are most likely to stop making healthy food choices and will send messages to remind participants of their weight loss goals. To participate in this study, you must be 18 to 70 years old, have overweight or obesity, and be at high risk of heart and blood vessel diseases. This study takes place in Providence, Rhode Island.

Does your child have overweight or obesity or just want to be in a study on sleep and eating habits? Overweight and obesity are common in children who do not get enough good quality sleep. This study aims to understand how sleep deficiency can affect a child’s ability to make good food choices. Researchers will ask participants to spend either 8 or 11 hours in bed and to keep track of their food choices. Participants in this study must be 8 to 12 years old. This study takes place in Pittsburgh, Pennsylvania and Providence, Rhode Island.
