Filter by:Parents are children's primary role models, are food and physical activity gatekeepers, and create the structure/lifestyle environment within the home. Thus, parents strongly influence children's weight-related behaviors and have the opportunity to cultivate a "culture of health" within the home. Yet, there continues to be a dearth of evidence-based obesity prevention intervention programs, especially for families with children aged 6 to 11 years, commonly called the middle childhood years. The aim of the HomeStyles-2 online learning mode RCT is to determine whether this novel, age-appropriate, family intervention enables and motivates parents to shape their home environments and weight-related lifestyle practices (i.e., diet, exercise, sleep) to be more supportive of optimal health and reduced risk of obesity in their middle childhood youth more than those in the control condition. The RCT will include the experimental group and an attention control group who will engage in a bona fide concurrent treatment different in subject matter but equal in nonspecific treatment effects. The participants will be families with school-age children who are systematically randomly assigned by computer to study condition. The HomeStyles intervention is predicated on the social cognitive theory and a social ecological framework. The RCT will collect sociodemographic characteristics of the participant, child, and partner/spouse; child and parent health status; parent weight-related cognitions; weight-related behaviors of the parent and child; and weight-related characteristics of the home environment. Enrollment for this study will begin mid-2021.This paper describes these aspects of the HomeStyles-2 intervention: rationale; sample eligibility criteria and recruitment; study design; experimental group intervention theoretical and philosophical underpinnings, structure, content, and development process; attention control intervention; survey instrument development and components; outcome measures; and planned analyses.
This project targets dietary lapses (instances of nonadherence to dietary goals), a major cause of poor outcomes during behavioral obesity treatment, which is a recommended first-line intervention for cardiovascular disease. The investigators propose to conduct a micro-randomized trial (MRT) to empirically optimize a smartphone-based just-in-time adaptive intervention (JITAI) that monitors risk and intervenes on lapses as needed. By evaluating the immediate, proximal effect of four theory-driven interventions on lapse behavior, the project will: (a) produce a scalable, finalized JITAI that has the greatest potential to show clear clinical impact in future trials; and (b) inform the development of more sophisticated theoretical models of adherence behavior more broadly. Therefore, this study has three goals. First the investigators aim to compare the effects of delivering any intervention to no intervention on the occurrence of lapse. Second, the investigators aim to compare the effects of specific theory-driven interventions to one another to determine which ones are best for preventing lapses. Within this second aim, the investigators also aim to examine other factors that may influence the effectiveness of interventions (e.g., time, location). Lastly, the investigators will use the data from this MRT to customize intervention delivery in future versions of this JITAI Patients will be recruited through various methods including advertisements in local media, targeted online advertising, advertisements in medical and minority communities, and direct mailers. All participants will receive a well-established 3-month online obesity treatment program, with 3 months of no-treatment follow-up. In conjunction, they will use a smartphone-based JITAI consisting of: 1) repeated daily surveys assess lapses and relevant triggers; 2) a machine learning algorithm that uses information from the surveys to determine real-time lapse risk; & 3) interventions to counter lapse risk. When an individual is at risk for lapsing she will be randomly assigned to no intervention, a generic risk alert, or one of 4 theory-driven interventions with interactive skills training. The outcome of interest will be the occurrence (or lack thereof) of dietary lapse, as measured both subjectively (i.e., reported by the participant in the daily surveys) and objectively (i.e., via wrist-based intake monitoring), in the hours following randomization initiated by heightened lapse risk.
Maternal and childhood obesity have dramatically increased and continue to present a significant health problem. Studies show that offspring of overweight (body mass index, BMI >25-29.9) and obese (BMI ≥30) women are at increased risk of newborn and age 1-year adiposity, and infant adiposity predicts childhood and adult obesity. The investigators hypothesize that infants of overweight/obese (OW/OB) mothers have both relative hyperphagia and are provided human milk with increased caloric composition, leading to obesity. The investigators propose an intervention study to calibrate milk or formula intake in infants of OW/OB mothers so as to avoid overweight infants at 6 months of age.
This study tests whether a high-fiber diet based on legumes, such as dry beans, can lead to sustained reductions in obesity and colon cancer risk in persons at highest risk, namely overweight or obese, post-polypectomy patients.
To examine response to a glucagon-like peptide-1 analogue vs. placebo in patients with obesity and assess impact on craving, hunger, stress, and weight outcomes.
This study aims to determine how different types of exercise regimens (resistance, aerobic, or combined exercise regimens) can be used to minimize muscle loss and mobilize body fat in severely obese patients after bariatric surgery (BS), despite the rapid surgery-induced weight loss. Additionally, the study will examine how changes in the intestinal microbiota following BS act as a mediation factor that alter tissue-specific responses in muscle and adipose tissue. The study will also evaluate the effect of different types of exercise regimens on cardiometabolic markers, endocrine response, and physical function following BS. Sixty sedentary (regular exercise <1 hour per week) candidates to bariatric surgery at Herzliya Medical Center will be recruited to participate in this six-month-long randomized control study. Participants will be randomly assigned to either one of three exercise regimens intervention groups (aerobic, resistance, or a combined exercise regimen combining aerobic and resistance exercises) or a control group that will receive standard care. Training will be supervised and matched for metabolic equivalent (METs). The intervention will take place at the Sylvan Adams Sports Institute at Tel Aviv University and an online platform. All measurements will be taken at a presurgical baseline assessment and throughout the study, and will include changes of muscle mass and adipose tissue distribution, measured by a 3-Tesla magnetic resonance imaging (MRI); body composition- will be assessed using multichannel bioelectrical impedance (Seca); Bone mass, will be measured by a Dual-energy X-ray absorptiometry (DEXA); microbiota composition and changes will be evaluated by stool samples that will be subjected to 16S ribosomal ribonucleic acid (16s rRNA) profiling and metagenomics analysis; fasting blood samples will be used to examine endocrine control and cardiometabolic markers; anthropometric measurements to assess surgery results associations with physical activity outcomes and physical function will be assessed by several validated performance assessments, including handgrip, six-minute walk, sit-to-stand, maximum voluntary contraction, and maximal oxygen consumption (VO2max).
Bilio-Pancreatic diversion with Duodenal Switch (BPD-DS) is the most effective bariatric procedure in terms of long-term weight loss and remission rate of Type 2 Diabetes. However, its technical difficulty and increased risk of long-term nutritional deficiencies have been a major hindrance to its diffusion. Recently, a " simplified " technique of Duodenal-Switch has been proposed by Sanchez-Pernaute et al. This technique involves the creation of a Sleeve Gastrectomy, transection of the first duodenum, and connection of the duodenum to an omega-loop of small bowel instead of a terminal intestinal loop used in standard BPD-DS. The overall objective of this study is to assess in a prospective randomized blinded trial, the outcomes of this new procedure, using a comprehensive clinical evaluation and follow-up method. This could potentially change the clinical practice and surgical approach in our Institution.
Obesity 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.
The rate of caesarean section is higher among obese pregnant women, leading to increased morbidity in this already vulnerable population. Oxytocin is the main drug used in obstetrics to optimize progress of labour, but observational studies have suggested that its efficiency may be insufficient in obese women with usual doses. We design a randomised controlled trial to test the effect of an increased oxytocin dose on the rate of caesarean section in obese primiparous women with spontaneous or induced labour.
The objective of the current study is to evaluate the effect of a probiotic mixture on the adequate relief and faecal microbiota in obese patients with irritable bowel syndrome
