The aim of the Reducing Obesity Using Social Ties (ROBUST) study is to address negative and positive social network processes that may influence weight loss among individuals enrolled in an evidence-based, 24-week lifestyle intervention modeled after the Diabetes Prevention Program.
This is a randomized controlled trial (RCT) of a tailored social network-enhanced lifestyle intervention compared to an individual-level lifestyle intervention (control group) in adults (N=132) who self-identify as Black or Hispanic and have obesity (BMI ≥ 30 kg/m2). Intervention participants will recruit up to two members (n=132) of their social network to participate in skill-building sessions. Intervention and control participants will receive fourteen nutrition and lifestyle coaching sessions over 24 weeks. Diet, physical activity, positive affect, social network processes, communal coping, and anthropometrics will be measured at baseline and after intervention completion at 24 weeks.
This study will provide the first pragmatic evidence of the efficacy of activating a communal coping process within personal networks to optimize weight loss among Black and Hispanic adults. Our study explicitly targets a population that has been less responsive to other lifestyle approaches to weight loss.
The study protocol was prospectively registered on ClinicalTrials.gov (NCT06335810).
“利用社会关系减少肥胖(ROBUST)”研究的目的是解决可能影响参与一项基于证据的、为期24周的、仿照糖尿病预防计划的生活方式干预的个体体重减轻的负面和正面社交网络过程。
这是一项随机对照试验(RCT),将一种量身定制的社交网络强化生活方式干预与个体层面的生活方式干预(对照组)进行比较,研究对象为132名自我认定为黑人或西班牙裔且患有肥胖症(BMI≥30 kg/m²)的成年人。干预组参与者将招募多达两名其社交网络中的成员(n = 132)参加技能培训课程。干预组和对照组参与者将在24周内接受14次营养和生活方式指导课程。将在基线时以及干预完成24周后测量饮食、身体活动、积极情绪、社交网络过程、共同应对方式和人体测量指标。
本研究将提供首个实用证据,证明激活个人网络中的共同应对过程以优化黑人和西班牙裔成年人的体重减轻效果。我们的研究明确针对的是对其他减肥生活方式反应较小的人群。
该研究方案已在ClinicalTrials.gov(NCT06335810)上进行了前瞻性注册。
