A prospective, large, pragmatic, randomized trial to study the impact of METFORMIN and healthy lifestyle intervention (LIFE) vs. LIFE alone on patient-centered outcomes of body weight, SGA-adherence and satisfaction, psychiatric symptom burden (e.g. mood/anxiety), and Quality of Life.
Multicenter, comparative single-dose pharmacokinetic (PK) study
The purpose of the research is to evaluate the digital wellness nurse (DWN) app to find out if it is helpful in delivering the FIT Families intervention. The study is sponsored by the National Institutes of Health (NIH).
The purpose of this study are to: 1. compare two diet plans - a low-glycemic load (low-GL) diet and a low-fat diet. A low-GL diet is expected to keep blood sugar levels more normal, and because the sugar levels stay normal, prevent rapid rises of insulin in the blood. We want to test if Hispanic children at-risk for type 2 diabetes who are given a low-GL diet will have less insulin resistance, will lose more weight, and will decrease their chance of getting type 2 diabetes. 2. compare the effects of Low-GL and high-GL meals on appetitive, hormonal, and metabolic responses of obese Hispanic youth under controlled, standardized conditions. We want to test if children fed low-GL meals would have lower glucose and lower insulin responses, report less hunger and consume less energy than those fed high-GL meals.
To compare anthropometric and metabolic effects of a comprehensive weight management program on obese adolescents and children in comparison to regular clinical weight management visits.
To study if continuous glucose monitors are feasible for use in children and adolescents with obesity.
The investigators propose a randomized controlled effectiveness trial to evaluate the integrated clinic-community model of child obesity treatment as compared with routine primary care.
Childhood obesity is a major public health issue, and the identification of children who are at increased risk of health problems due to their obesity is a priority for modern health care. Abdominal fat is considered to be the most harmful in the body, and the development of reliable landmarks and procedures for the assessment of intra-abdominal visceral adipose tissue and total body fat in children will have a major impact on 1) the early identification of children at elevated health risk, 2) the proper prioritization of health care resources, and 3) the standardization of obesity surveillance procedures within and between countries.
Obesity is a condition affecting one-third off the U.S. population and is a major risk actor for the development of Type 2 diabetes, hyperlipidemia (increased levels of fat in the blood), hypertension (high blood pressure), and other disorders of the heart and lungs. Individuals with the onset of obesity during childhood or adolescence are at an increased risk of obesity-related, diseases, both during adolescence and later in adult life. African American girls and women are at an increased risk for obesity, and have substantial rates of obesity-related diseases and causes of death. Further, many African American adult women fail to respond to many of the therapeutic approaches used to treat obesity. At present there are no medical therapies proven effective for the correction of severe obesity in children or adolescents. One medication that may have a favorable risk-benefit ratio in pediatric populations is Orlistat (Xenical, Hoffmann LaRoche). Orlistat works by preventing the action of enzymes in the digestive process, interfering with the absorption of approximately 1/3 of the fat eaten in the diet. Xenical appears to be effective for reducing weight and obesity-associated diseases in obese adults. Researchers propose to determine the safety, tolerability, and efficacy of Xenical in 12-17 year old severely obese African American and Caucasian children and adolescents who have one or more obesity-related disease (hypertension, hyperlipidemia, sleep apnea, hepatic steatosis, insulin resistance, impaired glucose tolerance, or Type 2 diabetes).
This is a 12 month prospective observational cohort study of the outpatient protein-sparing modified fast diet for children with severe obesity and serious comorbid condition(s). The study will enroll 30 Center for Healthy Weight and Nutrition patients aged 11-19 years who have been placed on a protein sparing modified fast as part of their treatment plan. The study-specific procedures consist of questionnaires/interviews on diet and PA behaviors, adherence and self-efficacy measures, data abstraction from the chart and tracking of activity using a Fitbit.
