Filter by:Comprehensive lifestyle interventions are recommended for the treatment of adolescent obesity; however, evidence suggests that they are not as effective in teens as they are in children and adults. Recent evidence supports that shifting the timing of energy intake earlier in the day has led to improved weight loss outcomes among adults with overweight and obesity. Given that adolescents traditionally consume the majority of their daily energy intake late in the day (past 5PM), this approach may improve the effectiveness of traditional behavioral weight control interventions in teens. Therefore, the primary aim of the proposed research is to pilot a novel adaptation of an evidence-based adolescent weight control intervention in which adolescents will be randomized to consume the majority of their daily energy needs earlier versus later in the day. More specifically, 40 adolescents, ages 13-17, with obesity (BMI>95% for age and sex) will be randomized to a 16-week evidence-based weight control intervention that has the participant consume >50 percent of their total energy intake before 3PM (i.e. at breakfast / lunch; BFL) or after 3PM (i.e. dinner; DIN). Assessments will take place at baseline and 16 weeks (post-treatment). The proposed study will test 1) the adherence and feasibility of the BFL vs. DIN interventions as measured by the average number of days on which daily energy was consumed in accordance with the prescribed eating plan and, secondarily, mean session attendance, 2) if the BFL group will have significantly greater reductions in BMI post-treatment as compared to the DIN group, 3) if there are differences in sleep duration and quality between groups, and finally, as an exploratory aim, whether there are differences in dietary quality between groups. The proposed research is significant, as it addresses obesity in teens. It is innovative as the timing of meals and snacks have not been manipulated in adolescents in the context of behavioral weight control. Moreover, the study will shed light on whether doing so improves sleep and could help to untangle how sleep and weight gain relate in adolescents.
Childhood obesity is a serious public health problem internationally. In addition to being associated with the early onset of chronic degenerative diseases such as diabetes, dyslipidemias, coronary artery diseases, among others. Changes in lifestyle habits are the main axis in the treatment of this disease; however, low adherence to these changes are reflected in the increase in their incidence and prevalence. There is diverse evidence that the use of flavonoids from cocoa such as (-) - epicatechin are able to prevent cardiovascular risks, decrease insulin resistance, mean arterial pressure, control the lipid profile; mediate oxidative stress, improve mitochondrial function and regulate the inflammatory process in patients with heart failure and diabetes mellitus. Therefore, our working hypothesis is the administration of the oral supplement of flavonoids from cocoa for 12 weeks will be able to reduce the percentage of body fat, improve the metabolic profile and regulate inflammatory and oxidative processes in obese patients 10-16 years, compared to those patients who only take a usual therapy consisting of recommendations of healthy diet and physical activity. For this, a randomized, double-blind, placebo-controlled clinical trial will be carried out, which will be carried out at the Federico Gómez Children's Hospital of Mexico, during the period from October 2019 to October 2020; with obese patients from 10 to 16 years distributed homogeneously at random in two groups: the control group (Placebo) and the intervention group (Flavonoids from cocoa) both groups affected for 12 weeks. The variables studied will be: percentage of muscle mass, percentage of fat, body mass index (BMI), waist circumference (CC), fasting glucose, fasting insulin, lipid profile (Total cholesterol, Triglycerides, HDL-c, LDL -c, Ratio TG / HDL-c, High Sensitivity C-Reactive Protein (HS-CRP), Interleukins (IL-6, IL-10), Tumor Growth Factor beta (TGF-β) and Tumoral Necrosis Factor alpha (TNF-α), carbonylated proteins, Malondialdehyde (MDA), indirect calorimetry by respiratory coefficient and treatment adherence.
This study intends to assess the role of inflammation in insulin resistant conditions (i.e., obesity and pre-diabetes) and the subsequent development of disease, such as type 2 diabetes (T2D) and cardiovascular disease (CVD), in the adolescent population.
This study will examine the timing and sequence of using adjunct obesity pharmacotherapy for adolescents with severe obesity who do not respond to lifestyle modification therapy alone.
This study is being conducted to assess weight loss efficacy, as determined by changes in body mass index (BMI), and safety of VI-0521 (Qsymia®) or placebo, taken for 56 weeks accompanied by a lifestyle modification program in obese adolescents age 12-16 years.
Girls with obesity and polycystic ovarian syndrome will receive either glucagon like peptide-1 receptor agonist therapy or a dietary intervention for 12 weeks to decrease the metabolic syndrome, in particular to lower hepatic fat and improve insulin sensitivity.
The US Preventive Services Task Force (USPSTF) recommends that providers screen children aged 6 years and older for obesity and offer or refer them to a comprehensive behavioral intervention (≥26 hours over a period of up to 12 months) to promote improvement in weight status. Family-based behavioral treatment (FBT) is an effective treatment that targets both child and parents and meets the USPSTF recommendations. By contrast, the American Medical Association (AMA) recommends a staged approach to childhood obesity screening and counseling, which begins with prevention counseling by the primary care provider (PCP) and includes assessment of weight status, patient/family motivation and readiness to change, promotion of healthy eating and activity habits, and use of health behavior change strategies. Our study compares a staged approach enhanced standard of care (eSOC) vs. eSOC + FBT, to provide families and PCPs with information on the best intervention approach for the behavioral treatment of childhood obesity. Our project seeks to fill the gap in the evidence on family-based weight management in primary care settings among diverse and underserved populations with a special focus on Black children, families insured by Medicaid, and sex differences.
Providers are not opportunistic enough in addressing lifestyle habits of teens, and can benefit from appropriate tools to support their conversations with families as well as engage all family members in making changes. Since most teens with obesity do not meet minimum lifestyle recommendations, our team developed Conversation Cards for Adolescents (CCAs), a tool to help teens and providers communicate and set lifestyle goals together. In this study, the investigators will (i) observe if and how CCAs fit in a clinical setting for changing teen-provider interactions and teens's lifestyle habits, (ii) ask teens and providers for their thoughts on CCAs and how they are used, and (iii) determine preliminary impact of CCAs on teen behaviors and clinical factors. The investigators will do this with around 50 teens from a primary/secondary care clinic in Edmonton, Alberta. Teens will be randomized to one of two groups - one group will use CCAs in their appointment with their providers to set a goal for change, while the other will also set a goal for change, but without using CCAs. Results from this study will give us insight into how CCAs are best used in a clinical setting and will help us plan a future full-scale study.
Prevalence rates of childhood obesity have reached alarming levels. As childhood obesity may already be associated with serious comorbidities, obese adolescents are at significantly higher risk for obesity and increased morbidity and mortality during adulthood. Combined lifestyle interventions, which include regular physical activity and dietary restriction, have been shown to result in most significant improvements in cardiovascular function and their associated factors in the pediatric and adolescent population with obesity. The aim of this study is to investigate the effects of a combined exercise and diet intervention on cardiovascular function and their associated factors in obese children.
Type 2 diabetes (T2D) in youth is increasing in prevalence in parallel with the obesity epidemic. In the US, almost half of patients with renal failure have DKD, and ≥80% have T2D. Compared to adult-onset T2D, youth with T2D have a more aggressive phenotype with greater insulin resistance (IR), more rapid β-cell decline and higher prevalence of diabetic kidney disease (DKD), arguing for separate and dedicated studies in youth-onset T2D. Early DKD is characterized by changes in intrarenal hemodynamic function, including increased renal plasma flow (RPF) and glomerular pressure with resultant hyperfiltration, is common in Y-T2D, and predicts progressive DKD. Studies evaluating the two currently approved medications for treating T2D in youth (metformin and insulin) have shown these medications are not able to improve β-cell function over time in the youth. However, recent evidence suggests that bariatric surgery in adults is associated with improvements in diabetes outcomes, and even T2D remission in many patients. Limited data in youth also supports the benefits of bariatric surgery, regarding weight loss, glycemic control in T2D, and cardio-renal health. While weight loss is important, the acute effect of bariatric surgery on factors such as insulin resistance likely includes weight loss-independent mechanisms. A better understanding of the effects of bariatric surgery on pancreatic function, intrarenal hemodynamics, renal O2 and cardiovascular function is critical to help define mechanisms of surgical benefits, to help identify potential novel future non-surgical approaches to prevent pancreatic failure, DKD and cardiovascular disease. The investigators' overarching hypotheses are that: 1) Y-T2D is associated with IR, pancreatic dysfunction, intrarenal hemodynamic dysfunction, elevated renal O2 consumption and cardiovascular dysfunction which improve with bariatric surgery, 2) The early effect of bariatric surgery on intrarenal hemodynamics is mediated by improvement in IR and weight loss. To address these hypotheses, the investigators will measure GFR, RPF, glomerular pressure and renal O2, in addition to aortic stiffness, β-cell function and insulin sensitivity in youth ages 12-21 with T2D (n=30) before and after vertical sleeve gastrectomy (VSG). To further investigate the mechanisms of renal damage in youth with T2D, two optional procedures are included in the study prior to vertical sleeve gastrectomy: 1) kidney biopsy procedure and 2) induction of induced pluripotent stem cells (iPSCs) to assess morphometrics and genetic expression of renal tissue.
