23 Clinical Trials for Various Conditions
Participants enrolled in the BfitBwell Cancer Exercise Program at the University of Colorado Cancer Center will be randomized 1:1 to receive the current BfitBwell program, or BfitBwell plus six, group-based behavior change counseling sessions adapted from BEAT Cancer. We will stratify the randomization based on sex.
This study is a two-arm trial, comparing the effects of a virtual 12-week group-based exercise intervention vs. control group on physical activity, physical fitness, and quality of life in colorectal cancer survivors, and explore multi-level determinants of physical activity maintenance, 6-months after intervention completion.
African American men are at risk of developing chronic disease partly due to low levels of regular physical activity. Studies have been effective in increasing physical activity levels in African American men; however for the health benefits of exercise to be maintained continued physical activity is necessary. The purpose of the current study is to develop a mobile phone application for African American men that will help them maintain their physical activity levels.
The proposed research seeks to determine whether virtual coaching and social support focusing on key social cognitive factors will be an effective strategy for maintaining physical activity (PA) after completing cardiac rehabilitation (CR). Despite the well-documented benefits of CR, only 15-50% of individuals continue to exercise 6 months after completing CR.4-6 Thus, after 36 sessions (typically 12 weeks), many patients are left without the support necessary to sustain physical activity (PA) and prevent adverse secondary cardiac events. Though previous research has explored interventions to sustain PA after CR, many studies have been lacking in a theoretical basis, objective measurement of PA, measurement, and analysis of psychosocial and social cognitive factors, and long-term impact on clinical outcomes. Low-cost, pragmatic approaches to maintaining PA after CR is urgently needed for older adults, and virtual technologies offer promising solutions to promote adherence to PA. The three specific aims of the project are to: 1) determine the effect of virtual coaching and social support on adherence to PA (measured by objective step counts) in the intervention vs. control groups; secondary measures will be amount of sedentary time, functional fitness, and self-reported exercise; 2) determine the effect of virtual coaching and social support on psychosocial and social cognitive factors in the intervention vs. control groups; 2a) evaluate the extent to which psychosocial and social cognitive factors mediate the effect of the intervention on PA adherence; 3) examine differences in cardiovascular (CVD) risk factors (blood pressure, lipids, HbA1c, BMI) between groups.
The purpose of this study is to determine whether a new phone and mail based coaching/support program that has been developed is more effective in helping people stay physically active than existing programs that are currently available to all HealthPartners members. We hypothesize that the intervention program will lead to a greater likelihood of physical activity maintenance among moderately active older adults than a usual care condition.
The goal of this clinical trial is to develop and test an adaptive physical activity (PA) maintenance intervention for cancer survivors, after participating in a community-based exercise oncology program. The main questions it aims to answer are: * Aim 1: Examine the feasibility and acceptability of the intervention among cancer survivors and community partners. The researchers will utilize quantitative surveys, focus groups, and semi-structured interviews to collect information about feasibility, implementation, adaptation, and sustainability. * Aim 2: Examine the effects of the intervention among cancer survivors. The researchers will compare the proportion of participants achieving the exercise guidelines for cancer survivors six-months following completion of the initial exercise program. Participants will participate in a community-based exercise oncology program and then return to three months of free living. Based on the PA measured at the three-month follow-up, participants will be categorized as a "Responder" or "Incomplete Responder", and then randomized to the PA maintenance intervention. Researchers will compare those that are classified as Responders (meeting exercise guidelines for cancer survivors) and Incomplete Responders (not meeting guidelines for cancer survivors) to see what level of intervention is needed to influence sustainable behavior change in this population.
This is a 3-arm trial to compare exercise videogames versus traditional standard exercise using stationary bikes and treadmills versus a control condition. Results will examine minutes of physical activity at 12 weeks and 6 month follow up between conditions. We will also examine changes in indicators of cardiovascular health (e.g., body mass index, lipids) and changes in psychological factors that may be predictive of continued exercise engagement.
The aim of this research is to evaluate the efficacy of contextually tailored activity suggestions and activity planning for increasing physical activity among sedentary adults.
The purpose of this study is to compare an technology-based weight maintenance intervention using action plans, videos discussion boards and health behavior tracking (weight, calories in and out, pedometer steps) with a technology-based standard advice group to facilitate health management, resourcefulness and health status for rural middle-aged women.
The purpose of this study is to test the efficacy of an evidence-based tailored physical activity program adapted for adults with acute leukemia. Implementation-related process evaluation of the physical activity program will also be assessed.
This study aims to test two strategies for weight loss maintenance. It involves two phases, a weight loss phase and a maintenance phase. During Phase I (the weight loss phase), participants will receive a 16-week, Web-based behavioral weight loss program that involves access to weekly weight loss information and weekly personalized feedback on diet, activity, and weight loss goals. Individuals who lose at least 5% of their initial body weight during this program, will be invited to participate in Phase II. During Phase II, two 4-month treatments for weight loss maintenance will be tested. At the beginning of Phase II, participants will be randomly assigned to one of the two maintenance programs: (1) a behavioral maintenance program that involves in-person group meetings plus daily exercises in which information about a healthy lifestyle is reviewed or (2) a behavioral maintenance program that involves in-person group meetings plus daily exercises in which descriptions of positive future events are reviewed. Throughout the study, participants will complete assessments that examine the effects of the interventions on delay discounting, physical activity, weight, and other important health and psychosocial outcomes.
Obesity is reaching epidemic proportions and threatens both health and quality of life of people around the world. While many individuals succeed at short term weight loss, weight loss maintenance is the greatest barrier to successful treatment of obesity. High levels of physical activity are consistently associated with success in weight loss maintenance. The major goal of this proposal is to understand how and why high levels of physical activity are critical for long term maintenance of weight loss. This project takes advantage of the National Weight Control Registry (NWCR), which follows over 6000 individuals who have maintained a weight loss of ≥30 pounds for ≥1 year. Understanding how individuals successful at weight loss maintenance achieve energy balance will provide important insight into strategies to help more people sustain a weight loss.
Exercise adoption enhances well-being and recovery from breast cancer. Researchers trained American Cancer Society volunteers to provide exercise counseling to breast cancer survivors and the survivors increased their exercise in the short-term. This RCT examines the effects of three maintenance conditions on survivors' exercise participation at longer follow-ups. The cost-effectiveness of the three groups will be examined to guide implementation of this peer mentoring approach in community-based organizations.
The primary purpose of this study is to assess the efficacy of the mobile phone-based physical activity intervention on increasing physical activity compared to the control group.
This research study is being done: 1) to determine if the MGH Be Fit program helps employees to change their nutrition and exercise habits and lower their risk for chronic diseases, such as heart disease and diabetes and 2) to determine if a maintenance program following the Be Fit 12 week program will help employees to keep the positive health changes.
Each year, a significant portion of men and women who engage in physical activities such as walking or running reduce their activity and by doing so place themselves at greater risk of obesity, heart disease, and diabetes. Our own prospective epidemiological studies of runners and walkers suggest that during 7.6 years of follow-up over 40% have reduced their mileage by half or more. Research suggests that social support, perceived health benefits, resiliency to interruptions in training, and exercise self-efficacy predict successful maintenance. We have found that runners who successfully maintained or increased their running mileage during this follow-up were more likely to have participated in social events such as marathon, half-marathon, or 10km races. The purpose of this study is to build upon our current Internet-based survey tools (www.healthsurvey.org) for tracking physical activity and nutrition on full-function activity and diet logs. The existing software allows participants to visualize their accumulated running and walking mileage on a virtual transcontinental route starting in Yorktown, Virginia and ending in Florence, Oregon. To the existing software, we will add the ability to: 1) choose named or anonymous running and walking partners with similar goals and abilities to travel with (or race against) along the transcontinental trail, 2) communicate with partners to provide mutual support, 3) compete as part of virtual running and walking teams created by the user, and 4) be recognized for completing each state on an awards page (optional). Interest in the site will be maintained by providing regular updates on scientific research on running and walking through our proprietary software. The updates will be created from PubMed abstracts that are made more reader friendly by defining all scientific terms in pop-up balloons.
The obesity epidemic observed in recent years can be largely attributed to an obesogenic environment that encourages overeating and sedentary lifestyles. Behavioral weight control treatment, the most empirically validated intervention approach, produces initial weight losses of 10%; however, maintenance of initial weight loss and behavior change has not been achieved. These disappointing long-term results may reflect the fact that participants are given only minimal, indirect instruction on how to change their environment to support their new weight-regulating behaviors. While in theory, the behavioral model emphasizes environmental antecedents and consequences of eating and exercise, in practice, only 1 to 2 sessions in standard treatment are dedicated to stimulus control-types of skills. By teaching weight control skills in a contextual vacuum, participants remain vulnerable to the same environmental influences that maintained their unhealthy eating and exercise habits. Given that the majority of eating and exercise is home-based, a logical step in strengthening behavioral treatment and moving toward an ecological model of behavior is to expand the focus of treatment from the individual to the individual plus their home environment. We propose to test the long-term impact of a behavioral weight control program designed to directly modify both the physical and social home environment of weight loss participants. Two hundred overweight and obese men and women will be randomly assigned to either 18 months of standard behavioral treatment (SBT) or 18 months of standard behavioral treatment plus direct modifications to the home environment (SBT+Home). SBT+Home will incorporate many strategies that have shown promise in improving weight loss (e.g., food and exercise equipment provision, spouse involvement) but will be the first to study both physical and social factors within the home simultaneously and will be the longest examination of the home environment conducted to date. Participants and spouses will be assessed at baseline, 6, 12, and 18 months. We hypothesize that by broadening the focus of treatment from the individual to the individual plus their home environment, SBT+Home will produce both better long-term weight loss and better maintenance of initial weight loss and behavior change. This home environmental approach, if successful, has potential applications to the maintenance of other important health behaviors.
The purpose of this study is to examine the effects of Tai Chi, in comparison to conventional exercise, on the quality of sleep among sedentary older adults.
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 study is sponsored by the National Heart, Lung, and Blood Institute, which is part of the National Institutes of Health. We expect to enroll 400 subjects into this study. We will be recruiting research participants that are finishing or will finish cardiac rehabilitation soon. Participants belong to one or more groups of people who are less often studied in cardiac rehabilitation research, may have less access to a formal cardiac rehabilitation maintenance program, or they may especially benefit from additional support after cardiac rehabilitation ends. The main purposes of this study are to evaluate which treatments work the best after cardiac rehabilitation, which order to deliver the treatments in, and which treatments are as minimally burdensome as possible while still working well. This study will make two comparisons (one comparison between a set of low-intensity interventions and another between a set of higher-intensity interventions) to determine which produces the best behavioral adherence immediately after Phase II (outpatient) cardiac rehabilitation
The primary aim of this study is to develop a feasible, acceptable, and effective multilevel physical activity (PA) intervention that addresses both individual and interpersonal factors that can be easily scalable and delivered in the context of a methadone clinic. To do so, the investigators will train methadone maintenance treatment (MMT) patients who are already engaging in PA at public health recommended levels to deliver a group-based PA intervention to physically inactive MMT patients at a large community-based methadone clinic. Through the development of interpersonal relationships and social support, the investigators expect that MMT peers who have successfully navigated challenges associated with PA in this population (i.e. depression, smoking, triggers for drug use in environment) will help physically inactive MMT patients increase self-efficacy and motivation for initiating and sustaining PA.
The purpose of the National Cancer Institute (NCI) funded randomized controlled study is to develop and evaluate a text message (SMS) based weight loss intervention to 309 overweight or moderately obese English and Spanish speaking adults ages 21 - 60. The investigators propose that participants randomized to the intervention arms will lose significantly more weight than those participants randomized to the control group.
H1: The increase in body mass index between baseline and two year follow-up among intervention worksites will be lower than that among control worksites, such that the differential change will be negative on average.
