Active clinical trials for "Obesity"

A 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.

The purpose of this study is to learn more about how the body stores fat in and around organs (for example in the liver) and why this affects some people's health more than others. Understanding this may lead to better treatments for diseases such as diabetes and cardiovascular disease.

Type 2 diabetes and obesity are both multifactorial diseases resulting from gene-environment interactions. However, this interaction, as well as the specific effect of each polymorphism, remains poorly understood. We now proposed a prospective cohort study to improve our understanding of the influence of phenotypic characteristics on gene expression in tissues involved in glucose and/or lipid metabolism by collecting different biological samples.

The 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

The goal of this clinical trial is to compare, in a population of severely obese patients, two different kinds of follow-up after discharge from in-hospital rehabilitation programme. The main questions addressed are: primary outcome: comparing the dropout rate at month 11 of patients followed-up by a telemedicine methodology with that of a traditional outpatient visit follow-up. secondary outcome: comparing the amount of weight loss at month 11 in patients followed-up by telemedicine with that registered in patients followed-up by traditional outpatient visits. Participants are given a set of instruments (scale, activity tracker, automatic blood pressure monitor, oxymeter, and glucometer) and asked to measure vital parameters following a predetermined schedule for one year. Subjects are asked to engage in regular physical activity and follow the nutritional guidelines received at the moment of discharge from hospital.

The goal of this cross-over study in obese subjects is to learn about the common co-morbidity type 2 diabetes and the local formation of ketone bodies. The type of study is an exploratory trial with the participants as own controls. The main questions it aims to answer are: 1. Does food intake-induced ketogenesis exist in the small intestine of obese individuals? 2. Are insulin resistance, the incretin GLP-1 release and the glucose transporter SGLT1 affected in obese individuals without type 2 diabetes in the same way as those with type 2 diabetes?

Although 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".

This is a prospective, randomized, open-label, active drug controlled clinical trial that aims to compare the effects of henagliflozin or metformin on myocardial tissue level characteristics in type 2 diabetes patients with obesity. Eligible subjects with type 2 diabetes before randomisation and fulfilling all of the inclusion criteria and none of the exclusion criteria will be randomised in a 1:1 ratio to henagliflozin 10 mg once a day or metformin 1000 mg twice a day and treated for 24 weeks. The study includes five visits.

The main goal of this prospective longitudinal observational study is to investigate the psychophysiological indicators by analyzing HRV, blood pressure, symptoms of anxiety and depression, eating behavior and quality of life during the follow-up of the general health status of patients with obesity undergoing the bariatric surgery by Roux-en-Y reconstruction reduction gastroplasty (GRYR) technique. The main question it aims to answer is: Does bariatric surgery changes the variables studied (HRV, anxiety, depression, eating behavior, quality of life)? Type of study: prospective longitudinal observational study Participant population: 50 patients, both females and males, aged between 18 and 60 years, will be submitted to bariatric surgery with Roux-en-Y reconstruction reduction gastroplasty technique. Patients will be evaluated for five times: before the bariatric surgery and 3-6-12-24 months after the bariatric surgery.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and one of the leading causes of infertility. PCOS and obesity affect up to 12.5% - 48.3% Asian women, increase incidence of impaired glucose tolerance, type 2 diabetes and aggravate insulin resistance, cause ovulatory dysfunction and menstrual disorders, and negatively impact outcomes of Assited Reproductive Technology (ART), with higher miscarriage rate when receiving ART. Weight loss decrease insulin resistance and hyperandrogenism, improve ovulation rate and menstrual cycle, significantly higher conception and live birth rates. Weight loss prior to IVF procedures has been associated with significantly improved pregnancy rates (PR) and live birth rates. Furthermore, a decreased number of IVF cycles required to achieve a pregnancy has also been reported after weight loss interventions. Based on the principles of fetal programming, improving a lifestyle before conception might lead to improved longterm health of the offspring. Studies on the effect of anti-obesity medication combined with lifestyle changes on body weight and composition and metabolic - endocrine parameters and pregnancy rate in obese women diagnosed with PCOS are lacking. There is a growing need to develop pharmacologic interventions to improve metabolic function in women with polycystic ovary syndrome (PCOS).
