A Protein-sparing Modified Fast for Children and Adolescents With Severe Obesity (PSMF)
ObesityChildhoodThis 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.

Lace Up and Move: Structured After School Intervention for Hispanic and African American Youth
Childhood ObesityObesity1 moreThe purpose of this study is to test the efficacy of Lace Up and Move (LUAM), a structured after-school exercise intervention, designed to increase moderate-to-vigorous physical activity (MVPA) and enhance sleep quality among Hispanic and African American (AA) boys and girls.

The Association Between Microbiota, Endotoxaemia and the Host Obesity/ Insulin Resistance (MiPOOP...
Central ObesityThe objectives of this study are to examine the effects of ethnicity, central obesity and dietary components, on the human gut microbiome. The investigators hypothesize that these factors have an influence on the composition of the gut microbiome. Healthy subjects (n=35) provided stool samples for gut microbiome profiling using 16S rRNA sequencing and completed a dietary questionnaire. The serum samples were assayed for a panel of inflammatory cytokines. Their associations with central obesity were examined.

A Personalized Program of Physical Activity and Diet for Hypothalamic Obesity
Hypothalamic ObesityHypothalamic obesity (HO) is an obesity secondary to an alteration of the functioning of the hypothalamus, the central organ of energy homeostasis. The causes of OH are related to an hypothalamic lesion (eg craniopharyngioma) or to genetic diseases (ex: Prader-Willi syndrome). OH, which accounts for about 5 to 10% of obesity, is a complex handicap characterized by severe obesity associated with eating disorders, cognitive and behavioral disorders and sometimes a visual deficit, with a major impact on quality of life, morbidity and mortality. There is currently no specific treatment of HO. Management is essentially behavioral, based on daily support of eating behavior and physical activities (PA). OH is characterized by an intense and almost permanent hunger felt, a satiety disorder and an obsessive interest in food. The food education of the entourage is essential, the advise concern the control of the access to food and the setting up of a precise food frame on the quantities, with low energetic density, and schedules. OH is characterized by obesity with lean mass deficit. PA must therefore be regular, adapted to the disability and personalized to take into account cognitive deficits and behavioral disorders. Although the supervision of meals and daily PA is now recognized as fundamental in the care of these patients (National Program of Diagnosis and Care established by the French "Haute Autorité de Santé"), few studies have evaluated the effectiveness of programs with personalized support on global health. The investigators hypothesize that a personalized 4-month individual home-based counseling program on dietary counseling and PA can be effective to modify behaviors such as diet and PAs with an impact on changing weight and quality of life. The 16-week program includes a dietetic component (initial assessment with dietary care plan followed by a 30-minute telephone interview every month with dietician) and a PA component (two 1-hour individualized sessions, performed at home and supervised by a PA educator). Before and after the program, the investigators will evaluate habitual PA with an accelerometer, feeding behavior, physical functioning, weight change, body composition, quality of life and will constitute a biobank of serums, adipose tissues and stools. If the effectiveness of this program is demonstrated this will help to find ways to sustain this support by the institutions, to train professionals in the complex accompaniment of these patients. Finally this program set up as part of a rare disease can show the benefits in other populations of more common pathology (common severe obesity, intellectual disability, behavioral disorders).

Gastrointestinal Physiological Conditions in Obesity and After Bariatric Surgery
ObesityBariatric Surgery CandidateOver the years, obesity has become a major public health concern. The increasing rates of obesity are associated with an enhanced demand for weight-loss with bariatric surgery as a treatment option. Bariatric surgery procedures alter the anatomical structure of the gastrointestinal tract, which contributes to the postoperative weight loss. However, it is not sure how obesity and the anatomical alterations of bariatric surgery affect the gastrointestinal physiology including gastrointestinal pH, gastric emptying, intestinal transit time and concentration of enzymes.

Central Obesity and Cancer Prevention for Chinese American Women
ObesityAbdominal1 moreThis project examines the feasibility of a smartphone-based intervention to reduce obesity and breast cancer risk among Chinese American women in San Francisco. The proposed intervention is to use the mobile application and an activity tracker device to promote a healthier lifestyle and physical activity. Ultimately, the findings will advance the NIH mission of enhancing health promotion and disease prevention.

Family Healthy Living Early Intervention Program
ObesityHealth Behavior4 moreThe Childhood Healthy Weights Early Intervention Program (EIP) is a family-based pilot program that will promote healthy lifestyle practices for families whose children are off the healthy weight trajectory (e.g., BMI ≥ 85th percentile for age and sex) that do not need the intensive services of medically supervised programs. It is a lifestyle behaviour approach for promoting healthy weights in children. The EIP program consists of 10 weekly intervention sessions (1.5 hours per session) followed by 4 maintenance sessions and is age specific (age 8-12). During the intervention, participants will also have access to digital educational content that is supplementary to what is provided during the individual sessions. The program will be integrated and aligned with existing BC-specific childhood healthy weights programs (e.g. the HealthLinkBC Eating and Activity Program for Kids). The EIP pilot will run from October-December 2018 with 8 child programs (age 8-12). Participants who do not qualify for this program (e.g., BMI ≤ 85th percentile for age and sex) will be offered a 10 week online program which is similar in educational content as the EIP program.

Awareness, Care & Treatment In Obesity Management - An International Observation
ObesityThe purpose of this survey is to collect the data on perceptions, behaviours and awareness related to obesity and obesity management for People with Obesity (PwO) and Health Care Professionals (HCP) treating obesity. Data will be collected via online surveys among each of the respondent groups. The surveys are expected to take approximately 25 minutes to complete and will be unique for PwO and HCP. As a cross-sectional study, there will be no treatment of patients.

Magnetic Resonance Imaging in Obesity
ObesityObesity and its related conditions account for up to 5%of all health care spending in the UK and this is expected to double by 2030. Following weight loss, significant improvement in these obesity-related illnesses has been reported. However, there is limited understanding of how these improvements happen and in particular, little dedicated work has been done using imaging in the obese population to look at the effects of treatment. Magnetic resonance imaging (MRI) is an imaging technique that allows assessment of fat concentration and volume without the use of ionising radiation. It is safe, non-invasive and well-tolerated by most patients. There are several MRI imaging techniques that be can used for fat quantification. These include MR spectroscopy and Dixon methods with measurement of fat fraction. These techniques measure the fat in the body organs and also the fat in the abdomen and skin. Recent technical developments mean that the whole body can be scanned relatively quickly (typically 30-40 minutes).
