170 Clinical Trials for Various Conditions
This study is a randomized clinical trial with the primary aim examining the efficacy of a novel integrated solution of a digitally delivered behavioral weight management program tailored for diabetes utilizing a continuous glucose monitor (CGM) built into the WW digital platform for adults with type 2 diabetes (T2D) for the reduction of HbA1c.
This study is a randomized controlled intervention trial in adults aged 50+ years with overweight or obesity, which will compare three groups with different diet prescriptions: 1) pre-meal water consumption (500 ml, before each main meal) with a hypocaloric diet; 2) 1500 ml water consumed throughout the day with a hypocaloric diet; 3) hypocaloric diet with no instructions regarding water consumption. Smart water bottles will objectively assess water intake timing and volume. Urine osmolality, urine volume, and serum osmolality will be used as objective indicators of compliance with the water intake prescription. We will investigate changes in perceived hunger and fullness and appetite-regulating hormones as potential mechanisms by which premeal water could improve appetite regulation. We will also investigate the impact of water consumption and hydration on executive function capabilities, which may influence intervention adherence. Although increasing water intake could be an effective weight management strategy, no evidence-based recommendations exist for the timing of water intake needed for this benefit.
The study is a randomized clinical trial with the primary aim of determining the effectiveness of the WW intervention at reducing HbA1c in patients with type 2 diabetes.
To study the effects of transcranial direct current stimulation (tDCS) on weight and appetite.
The IWCR is a global scientific study aimed at better understanding the opportunities and barriers for reducing the prevalence of obesity by collecting information from people who have experience with weight management in their everyday lives. The investigators seek to gather information on a wide range of weight management experiences, ranging from weight loss and weight loss maintenance to weight gain and inability to lose weight.
The prevalence of obesity in adolescents is remarkably high, with 38.7% of youth 12-15 years of age and 41.5% of 16-19 year olds meeting criteria for overweight or obesity. Behavioral weight control interventions for adolescents have had limited impact on this field and there is considerably more that needs to be done. Notably, adolescents who have difficulty managing their feelings have been found to consume higher caloric foods and report greater amounts of sedentary time. Poor emotion management among adolescents has also been associated with more rapid weight gain and higher BMI. Data from adolescents with overweight/obesity attending our outpatient weight management program (N=124) indicate that 82% of these youth report emotion regulation scores that are comparable to youth with significant mental health problems. Despite documented relationships between adolescent weight control and emotion regulation, no proven adolescent weight management programs targeting emotion regulation exist. To fill this gap, our laboratory developed and piloted an adolescent weight control intervention (HealthTRAC) that combines two previously tested effective interventions, one targeting emotion regulation skill building, the other focused on behavioral weight control. Findings from our small pilot trial are promising and indicate that the newly created HealthTRAC intervention is acceptable to parents and teens, easy to deliver, and leads to modest weight loss and improved emotion management skills compared to a standard behavioral weight control (SBWC) program. These data suggest that emotion regulation is related to weight management and may assist adolescents with overweight/obesity who are seeking to lose weight. The current multi-site study builds on this previous work and will examine the impact of the developed HealthTRAC intervention on improving emotion regulation skills and reducing adolescent BMI in a larger sample with longer term follow-up (18 months after starting the intervention). Adolescents will receive 27.5 hours of intervention time over a 12- month period. We expect that adolescents enrolled in the HealthTRAC intervention will show greater reduction in BMI over the 12-month program and will sustain these losses up to 18 months after starting the intervention compared to teens enrolled in SBWC. The information learned from this project will help us better understand how helping adolescents manage their emotions can improve weight loss outcomes.
The purpose of the study is to evaluate the effect of the WW program on people with Type 2 diabetes and the effect on glycemic control. This study will be a 6 month prospective, single arm clinical trial coordinated by Pennington Biomedical Research Center. Up to 150 participants will be recruited across 3 sites. Participants will have Type 2 diabetes and overweight/obesity.
A 2-arm, parallel group, randomized controlled trial to evaluate overall differences in body mass index (BMI) trajectories over 6 months between 10-16-year-old children with obesity randomized to receive the wise social psychological interventions plus a usual care behavioral intervention for weight management compared to children randomized to receive additional education plus a usual care behavioral intervention.
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.
This study looks at a new study medicine for weight control in people with overweight or obesity. The aim of this study is to see if the study medicine is safe for people to take. The study also looks at how fast the body removes the study medicine. The participants will either get NNC0194-0499 (the study medicine) or placebo (a formula that looks like the medicine but does not have active ingredients). Which treatment the participants get is decided by chance. The participants will get 1 or more injections into the skin of stomach area once each week for 12 weeks. The study will last for about 4 to 5 months. The participants will have 18 visits to the clinic.
The objective of this project is to determine the biological, neurobehavioral, and behavioral compensatory responses to exercise training-induced energy deficits in overweight to obese men and women. Participants will engage in exercise at either 2 days or 6 days per week for 12 weeks and have body composition assessed via DXA before and after the exercise intervention. Accumulated energy balance (weight loss converted to kcal) will be compared to exercise energy expenditure to determine each individual's level of compensation, termed compensation index. Predictors of compensation index that will be assessed will include hunger/satiety hormone concentrations at rest and in response to a meal, reward driven feeding, changes in metabolic rate, and energy intake throughout the intervention. Exercise reinforcement and physical activity will also be assessed as a separate aim to determine if exercise reinforcement can be increased and if this can promote greater habitual physical activity after the intervention has ceased.
Community-based programs are needed to improve dissemination of efficacious treatment for adolescent obesity. The current study aims to modify a community-based program, delivered through the YMCA, to increase its effectiveness with adolescents. Adolescents will be randomized to either a 16-week standard program (JOIN) or a targeted intervention tailored for adolescents (TEEN JOIN). Primary outcomes include changes in BMI, objectively measured physical activity, and self-efficacy, assessed at 4 months and 10 months following randomization.
The purpose of this study is to research the effects of exercise on calories eaten and expended. The investigator expects to find out whether subjects change their eating and activity behaviors when starting an exercise program.
This randomized controlled trial compares the effectiveness for both smoking cessation and weight control of two alternative combined interventions offered via telephone quitline, as compared to standard of care quitline treatment addressing cessation alone. The interventions to be compared are cessation treatment alone versus cessation treatment combined with weight control treatment added either simultaneously or sequentially.
The specific objective of this research proposal is to determine the short-term efficacy of a primary care-based weight control intervention in which successful volunteer peers deliver a group-based program. The purpose of the study is to conduct a pilot randomized controlled trial (RCT) of a successful volunteer peer-led weight control program compared to a control condition to determine intervention efficacy at 3 months. Six peer leaders from 2 primary care clinics will be recruited and trained to conduct the intervention. Overweight and obese patients (n=80) will be recruited (randomized by individual) to determine weight loss at 3 months (primary outcome). The program consists of 12 weekly weight loss sessions led by a successful volunteer peer leader using an adaptation of the Diabetes Prevention Program to help participants lose weight.
The Delta Healthy Sprouts Project is a randomized, controlled trial evaluating the enhancement of an existing Mother, Infant, and Early Childhood Home Visiting Program in 150 African American women in their early second trimester of pregnancy. The control arm, Parents as Teachers, is an evidence-based approach to increase parental knowledge of child development and improve parenting practices. The experimental arm, Parents as Teachers Enhanced, builds on the Parents as Teachers curriculum by including nutrition and physical activity components specifically designed for the gestational and postnatal periods. Both arms of the intervention will be implemented by community-based, trained Parent Educators. The comparative effectiveness of the two intervention arms on weight status, dietary intake, and health behaviors of mothers and their infants will be assessed. The Delta Healthy Sprouts Project will determine if a novel, scalable, lifestyle intervention can improve the health of African American women and their children at high-risk for obesity and chronic disease.
The purpose of this study is to compare three methods of delivering behavioral weight loss treatment.Participants are randomly assigned to one of three 18-month weight loss treatments (group, individual, or smartphone treatment). Participants who are assigned to group treatment will attend group meetings weekly for the first 6 months, then every 2 weeks for 6 months, and then monthly for the final 6 months. Participants who are assigned to individual treatment will attend one-on-one sessions with a weight loss counselor every month for 18 months. Participants who are assigned to smartphone treatment will use a smartphone to learn and practice weight loss skills. They will also attend one-on-one sessions with a weight loss counselor every month for 18 months. Assessment visits are conducted at baseline, 6, 12, and 18 months.
The investigators will conduct a randomized controlled trial comparing the effects of three interventions on weight loss at 12 months. The investigators propose to test the impact of integrating an effective automated Internet weight control program into primary care by recruiting patients and randomizing them to one of three conditions: A) Brief physician counseling plus usual care, B) Brief physician counseling plus referral and access to the Internet weight control program and, C) Brief physician counseling plus referral and access to the Internet weight control program plus brief follow-up email notes of support and accountability from Primary Care Physicians. The investigators hypothesize that an online program for weight control can be more effective by enhancing online follow-up with PCPs.
In the United States, overweight (BMI \> 25 but \< 30 Kg/m2) and obesity (BMI \> 30Kg/m2) are increasing at epidemic rates. A significant association exists between being overweight or obese and breast cancer recurrence and survival. However, evidence continues to accumulate indicating that achieving or maintaining a healthy weight for height (Body Mass Index, BMI, 18.5-25Kg/m2) is associated with a reduced risk for breast cancer and with a decrease in breast cancer associated mortality. Despite this, there is a lack of randomized controlled trials exploring this association and how the process of fat loss or being successful in actually reaching a healthy weight for height differentially affects biomarkers for cancer recurrence. Many dietary approaches for weight loss are currently available to the public, and each purports to offer advantages. However, there is little scientific evidence to indicate how these dietary approaches, some of which vary markedly in the foods that they limit or exclude, affect biomarkers for breast cancer risk. In particular, it is not know whether the critical factor in relation to weight and breast cancer is simply weight loss (negative energy balance), irrespective of the manner in which it is achieved, or if certain dietary approaches affect breast cancer risk biomarkers more favorably than others. Published data from our laboratory suggest that dietary pattern does matter, and therefore the goal of this study is to investigate the effects of two popular weight loss dietary approaches that differ in the extent to which they limit carbohydrate or fat consumption (with effects on dietary glycemic load) compared to a usual care group on prognostic markers for cancer recurrence in postmenopausal breast cancer survivors. The investigators hypothesize that in addition to the anticipated effects of fat loss on circulating levels of bioavailable sex steroid hormones, that the effects of excess fat on breast cancer prognosis can be attributed to three interrelated metabolic processes that affect cancer progression: altered glucose metabolism, chronic inflammation and excessive cellular oxidation.
The Social/Mobile Approach to Reduce Weight (SMART) study is a 24-month randomized control trial designed to evaluate the hypothesis that weight status at 24 months will be significantly better for the SMART intervention recipients than for those who receive the comparison condition.
The purpose of this National Cancer Institute (NCI) funded study is to develop and test the acceptability and usability of a web \& text message based weight loss intervention for childhood acute lymphoblastic leukemia (ALL) survivors. Childhood cancer survivors ages 7 - 18 will provide feedback during focus groups on a web and text message based program that was developed.
The purpose of this study is to examine how adults can improve their physical activity levels and eating habits using an interactive web-based weight control program and regular contact with a dietician.
The purpose of this study is to evaluate the short-term effect of a technology based weight reduction program for obese (BMI \> 30 kg/m2) adults in a primary care office.
The aim of this study is to evaluate the effectiveness, safety, and tolerability of metformin treatment in children and adolescents suffering from weight gain secondary to use of atypical antipsychotic medications. In this 12 week, open-label study we will investigate metformin's effects on weight control and/or weight loss. We hypothesize that metformin would prevent further weight gain or lead to weight loss, resulting in amelioration of one of the most significant side effects of atypical antipsychotic use.
RATIONALE: Computer-based continuing education courses may be effective in improving the skills of primary care doctors to identify skin cancer risk factors, perform skin cancer exams, and counsel patients. They may also improve the skills of primary care doctors to assess and counsel patients on their weight, diet, and physical activity. PURPOSE: This randomized clinical trial is studying how well computer-based continuing education courses work in improving doctors' ability to perform skin cancer or weight control exams and counseling during routine office visits.
The purpose of this study is to determine whether a home-based exercise and weight control program applied to elderly overweight individuals with painful osteoarthritis of the knee, would result in pain reduction.
The purpose of this study is to determine if an internet-based intervention designed to reduce binge eating and improve healthy weight regulation skills will result in reductions in binge eating and weight loss, or weight maintenance, in overweight adolescents who binge eat.
This randomized clinical trial will determine the efficacy of physicians providing weight control advice to their overweight and obese patients in primary care practice.
The purpose of this study is to determine whether the addition of bupropion (Zyban) to cognitive behavioral therapy (CBT) will enhance longer-term tobacco abstinence in women.
The study aimed to investigate 1) if a brief, regulatory focus-based intervention could promote weight control and changes in certain lifestyle behaviors and 2) how weight was affected by changes in these behaviors. The lifestyle behaviors of interest included meal regularity, self-monitoring of diet and physical activity, fast-food eating, screen related viewing and eating, dietary modifications, self-weighing, and physical activity. It was hypothesized that increases in meal regularity, self-monitoring, healthy dietary modifications, self-weighing, and physical activity would lead to better weight control over six months. Conversely, it was hypothesized that increases in fast food consumption and screen related eating and viewing would lead to poorer weight control over six months. It was expected that promotion and prevention conditions, relative to the control condition, would lead to better weight control and increases in meal regularity, self-monitoring, healthy dietary modifications, self-weighing, and physical activity, and decreases in fast food consumption and screen related eating and viewing. Furthermore, it was expected that the promotion condition would lead to better outcomes than the prevention condition.
