简要总结
Emerging adulthood (18-25 years of age) is a critical developmental window to promote weight management and cardiometabolic health, particularly for emerging adult women. The primary purpose of this study is to test the preliminary efficacy of the intensive lifestyle intervention for EA women in reducing adiposity, as well as improving biomarkers of inflammation and metabolic risk over 12 months compared with a traditional behavioral weight loss intervention. This treatment program will be tested in emerging adult (EA) women ages 18-25 years old with a BMI of 25-50 kg/m^2.
详细描述
This is a 2-arm, parallel randomized controlled pilot trial designed to test the preliminary efficacy of a novel integrated lifestyle intervention for emerging adult (EA) women, compared to a developmentally adapted behavioral weight loss arm. Thirty-two participants (female, 18-25 years, BMI 25-50 kg/m^2) will be randomized to 1 of 2 arms: 1) Integrated Lifestyle Intervention (ILI); or 2) Behavioral Weight Loss (BWL). The primary goals are to test the preliminary efficacy of ILI to reduce adiposity over 12 months compared to BWL, and to test the preliminary efficacy of ILI to improve biomarkers of inflammation and cardiometabolic risk over 12 months compared with BWL. Assessments of adiposity, inflammatory cytokines, cardiovascular disease (CVD) risk factors, and behavioral and psychological treatment targets will occur at 0, 4, 8 and 12 months. In addition, putative psychological mechanisms of action will be explored to inform a future trial.

研究组 & 干预措施
Integrated Lifestyle Intervention (ILI)
ILI participants will receive training in empirically supported strategies to improve psychological function (e.g., restructuring negative thoughts, distress tolerance), with a focus on changing discrete behaviors linked to inflammation (e.g., sleep, processed foods, physical activity), all intertwined with BWL content adapted to meet the needs of EAs.
All participants will receive digital tools to facilitate self-monitoring-the initial 4-month program will consist of group sessions via Zoom (8 weekly, 4 bi-weekly) with weekly tailored e-coaching, followed by monthly boosters through 12 months.
