Adolescents Bariatric Surgery Cohort Survey
Bariatric Surgery CandidateObesity3 moreObesity affects 3%-4% of the pediatric population and leads to cardiac mortality during adult life. Bariatric surgery is the best treatment for weight loss and preventing obesity associated comorbidities in adults, but its applications and safety are yet to be defined for adolescents.

Greenlight Plus Study: Approaches to Early Childhood Obesity Prevention
BehaviorHealth1 moreA randomized controlled trial enrolling 900 parent-infant dyads (English and Spanish speaking) comparing Greenlight (control), a behavioral intervention focusing on nutrition, physical activity, media use, and sleep as compared to Greenlight Plus (intervention) which includes the above materials plus a health information technology (HIT) intervention aimed at supporting family goal-setting and behavior change during well-child checks throughout the first 2 years of life.

Starting Early Obesity Prevention Program
Childhood ObesityThe proposed study is a randomized controlled trial to test the effectiveness of a primary care, family-centered child obesity prevention program beginning in pregnancy and continuing throughout the first three years of life compared to routine standard of care. The study aims to reduce the prevalence of obesity at age three, improve child diet composition and healthy lifestyle behaviors. Pregnant women will be enrolled from a large urban medical center serving primarily low-income immigrant Latino families. The intervention "Starting Early" will consist of three components. 1) Family Groups: interactive groups coordinated with the child's primary care visits and led by a Nutritionist/ Child Developmental Specialist. 2) Nutritional Video: a culturally-specific bilingual early nutrition video will be incorporated into family group discussions. 3) Plain Language Handouts: given to reinforce the curriculum from the family groups. The proposed research included in the funding continuation is titled: "Starting Early: Expansion of a Primary Care-Based Early Child Obesity Prevention Program". It adds three major components to the current project: 1) Following the original Starting Early cohort until age 5; 2) Developing and piloting an extended Starting Early preschool intervention for children aged 3-5 years.; 3) Developing and piloting an extended Starting Early prenatal intervention for women in the 1st trimester of pregnancy. A new cohort of 200 women in the first trimester of pregnancy will be recruited for the prenatal intervention; all women will receive the intervention in this feasibility trial. Hypothesis: Compared to controls, the intervention group will show reduced obesity and improved parent feeding knowledge and increased healthy feeding attitudes, styles and practices

Pedicatric Obesity - Weight - Energy - Loss - Load
Pediatric ObesityAlthough multidisciplinary treatment of pediatric obesity has shown its effectiveness in leading to weight loss and improvement in the physical, mental and social health of children and adolescents; maintaining these benefits remains a real challenge. Indeed, the literature clearly shows a short- to medium-term increase in weight, the mechanisms of which have yet to be identified in order to prevent it. Although cognitive, behavioral and nutritional adaptations have been highlighted to explain this weight regain, metabolic and energetic adaptations also seem to contribute. Indeed, a reduction in resting and total energy expenditure has been shown (in connection with changes in body composition and in particular lean mass), but also of the energy cost during locomotion and mobility, thus altering the daily energy balance. These energy adaptations are also accompanied by a modification in the use of energy substrates due to a modification of muscular metabolic flexibility in particular, leading to a reduction in lipid oxidation in favor of carbohydrates. Importantly, if this reduction in the use of lipids generates a counterproductive sparing of adipose tissue, thus slowing down weight loss, the increase in carbohydrate oxidation leads to an intensification of orexigenic signals at the central level, promoting nutritional compensations and positive energy balance and therefore contributing to weight regain. Thus, these adaptations of energy metabolism and their interactions with dietary control seem to be at the heart of the mechanisms limiting the success of obesity treatment, favoring weight gain. If these observations were made at the end of treatment programs lasting several weeks to months, a recent clinical work highlights the need to consider the kinetics and temporality of weight loss (weight loss variability and rate of weight loss), so as to identify the crucial stages where these adaptations take place and thus prevent their energy consequences. Thus, the main objective of this project is to study total energy adaptations (energy and nutritional metabolism) at rest but also during locomotion, during the central phase of weight loss of adolescents with obesity, as well as during phases of weight regain. Ultimately, the objective of this study is to better understand energetic adaptations to weight loss and the implication of the degree of weight loss in order to study the role of the interaction between these adaptations and the degree of weight loss on the success of programs and on the profiles of "weight maintainers" or "weight regainers".

Stay In Treatment for Pediatric Weight Management
Pediatric ObesityAttrition2 moreAttrition from pediatric weight management programs is unacceptably high, with dropout ranging from 27-73%. This project will utilize a model that predicts dropout from treatment, increasing its power and accuracy through a multi-site observational study. This will result in a powerful tool that will be used to decrease attrition from pediatric weight management, with the potential for widespread dissemination to improve treatment outcomes.

Maternal Grandmothers in the Born in Guangzhou Cohort Study
Hereditary TransmissionImmune Development3 moreThe MGBIG is a study exploring cross-generational effects in 5000 women and their children and grandchildren located in Guangzhou, China. Its initial aim is to facilitate research on understanding the interplay between genes and environmental factors on disease etiology and on explaining the cause of the disease from the perspective of "grandmother-mother-child" heredity. Data are collected regarding environmental exposures, lifestyle, and social support on grandmother from birth to old age. Biological samples including blood and tissue samples are collected.

Fit 5 Kids Screen Time Reduction Curriculum for Latino Preschoolers
ObesityChildhood2 moreChildhood obesity and metabolic risk are at record high levels in the US, and Latino children are at very high risk. This project will test an intervention called Fit 5 Kids, designed for Latino preschoolers to decrease their screen time in order to promote physical activity and healthy eating, and to prevent obesity. Ultimately, this line of research has the potential to provide an effective program to reduce risk of obesity for Latinos in the Head Start program and other preschool-based settings.

Your COACH Next Door Study
