7 Clinical Trials for Various Conditions
The goal of this exploratory/ developmental study is to develop and evaluate an integrated information system, Healthy Eating and Activity Today (HEAT), for promoting self-care in overweight children. HEAT is comprised of two components: 1)Telephone Linked Care-HEAT (TLC-HEAT), a self-care intervention delivered at home through totally automated telephone conversations; and 2) Primary Care-HEAT (PC-HEAT), a primary care intervention linked with TLC-HEAT and delivered through an electronic health record (EHR). The HEAT system will guide children in the early stages of overweight, i.e., children with Body Mass Index (BMI) 0-3 BMI points above the 95th percentile for age and gender, toward healthy weight management and assist the child's parent(s) and primary care provider (PCP) to support the child's efforts.
The purpose of this study is to examine the effect of an enhanced technology-based system, that involves a wearable device to measure calories burned combined with a website, in comparison to previous versions of similar technology and a standard behavioral weight loss on body weight across 6 months in obese adults.
The purpose of this study is to find out whether a technology-base healthy lifestyle program is an acceptable and effective way for African-American mothers to improve their eating and activity during pregnancy, compared to usual obstetric care. The goal of the program is to enhance the health of African-American mothers and their babies.
The purpose of this study is to determine the feasibility and acceptability and efficacy of a two month technology-based weight loss program for overweight and obese college students.
The primary aim of this study is to compare the changes in body weight between a technology-based system, an in-person behavioral weight loss intervention, and a combination of both during a 12 month behavioral weight loss intervention in adults. Sedentary, healthy overweight and obese adults will be recruited to participate. Assessments will be conducted at 0, 6, and 12 months. This is a randomized trial in which participants will be randomized to one of three groups: standard behavioral weight loss (SBWL), standard behavioral weight loss plus technology (SBWL+TECH), and technology alone alone (TECH).
The proposed multi-site randomized control trial (RCT) will test the effectiveness of an addiction-based weight loss intervention, embodied first as a smartphone app with telephone coaching and second as an identical approach phone-coaching alone intervention compared to age matched controls participating in an in-clinic weight management interventions in a larger sample of economically, racially and ethnically diverse adolescents (ages 14-18). One hundred and eighty adolescents will be recruited from pediatric interdisciplinary weight management clinics operating out of five different hospital systems in Southern California and through targeted mailing to 40 ethnically, racially and economically diverse neighborhoods in Los Angeles County. The adolescents will be randomized 1:1 via stratified block randomization to either receive 1) interactive addiction model based mobile health (mHealth) weight-loss intervention with personalized phone-coaching (AppCoach), 2) interactive addiction model based mHealth weight-loss intervention alone (App) or 3) Multidisciplinary in-clinic weight management program (Clinic). Assessment of the intervention's effect on zBMI and percent over the 95th percentile (%BMIp95), fasting metabolic parameters, addictive eating habits, executive function, and motivation for change will be obtained at enrollment, 3, 6, 12 and 18 months (1 year post intervention follow up).
Previous studies suggest self-regulatory techniques including self-monitoring, and SMS text-messaging as an intervention modality, can modify health behaviors including physical activity (PA). The primary purpose of this study was to examine change in objectively measured PA in a randomized controlled pilot trial that tested a wearable sensor/device (Fitbit One) for self-monitoring and SMS text-messaging prompts to promote PA in overweight/obese adults. In a 2-group design, 67 participants were provided the Fitbit One and half were randomized to receive 3 daily SMS-based PA prompts. A Fitbit One was provided to facilitate self-monitoring with a wearable tracker for instant feedback and website of daily PA summaries. Outcome measures were number of steps and minutes of PA by intensity-level using two accelerometers: Actigraph GT3X+ (primary) at baseline and 6-week follow-up and Fitbit One (secondary) at baseline and weeks 1-6. The main hypothesis was that text messaging plus the Fitbit One would show a greater increase in steps and minutes of PA compared to only the Fitbit One at 6-week follow-up.
