SMART: A Social and Mobile Weight Control Program for Young Adults

描述(由申请者提供)：体重增加和肥胖的问题在青壮年很重要。当个人经历从青春期到成年早期的人生道路时，无论他们是否上大学、参军或高中毕业后进入劳动力大军，他们都会遇到导致体重增加的多重压力和影响。体重增加反过来会增加患心血管疾病、糖尿病和其他健康问题的风险。关于如何在这一人群中进行干预以防止体重增加或使体重减轻，人们知之甚少。我们建议进行形成性研究，以开发一种干预、社交/移动方式来减轻体重(SMART)，以防止体重增加，并促进有体重增加风险的年轻人减肥。然后，我们将在406名参与者中进行随机对照试验，以评估SMART在12个月和24个月时对体重状况和其他代谢、行为和心理社会结果的影响。SMART将是一种基于理论的干预，将网络、手机和社交媒体组件结合到一个引人入胜的体重控制计划中。该项目将建立在我们之前的干预研究工作的基础上，以改善与体重相关的行为和体重结果，以及基于手机的行为干预。我们将在圣地亚哥与斯坦福大学的研究人员合作，对SMART进行形成性研究。随后将开发最终的智能软件体系结构和系统。然后，将进行为期两年的随机对照试验，以评估SMART对体重相关结果的影响。这项研究的主要目标将是两组人在24个月时的体重状况(公斤)的差异：a)那些在基线时体重正常的人，以评估智能对预防体重增加的支持程度；以及b)基线时超重/肥胖的参与者，他们将接受体重减轻评估。将在两组中招募足够数量的参与者来评估这些结果。这项研究的次要和探索性目标将是检查与干预、使用和满意度有关的其他与健康相关的结果和过程措施。相关性(参见说明)：超重/肥胖是美国非常普遍的疾病，影响大约66%的成年人口。降低肥胖症的总体发病率是一个主要的公共卫生问题，但人们对如何在年轻人中做到这一点知之甚少。这项研究将解决这一知识差距。(摘要结束)

DESCRIPTION (provided by applicant): The problem of weight gain and obesity is important in young adulthood. As individuals traverse life paths from adolescence into early adulthood, whether or not they attend college, join the military or enter the workforce out of high school, they encounter multiple stressors and influences that contribute to weight gain. Weight gain in turn leads to increase risk of cardiovascular disease, diabetes and other health problems. Little is known about how to intervene to prevent weight gain or enable weight loss in this population. We propose to conduct formative research to develop an intervention, Social/Mobile Approach to Reduce Weight (SMART) to prevent weight gain and promote weight loss in young adults at risk for weight gain. We will then conduct a randomized controlled trial in 406 participants to evaluate the effects on weight status and other metabolic, behavioral and psychosocial outcomes of SMART at 12 and 24 months. SMART will be a theory- based intervention that combines web, mobile phone and social media components into an engaging weight control program. The project will build on our prior work in intervention research to improve weight-related behaviors and weight outcomes and in mobile phone based behavioral interventions. We will perform formative research on SMART in San Diego and in collaboration with researchers at Stanford University. This will be followed by development of the final SMART software architecture and system. Then a 2-year randomized controlled trial will be conducted to evaluate the effects of SMART on weight-related outcomes. The primary aims of the study will be differences in weight status (kg) at 24 months among two groups: a) Those with a normal weight at baseline to evaluate how well SMART supports the prevention of weight gain; and b) Overweight/obese participants at baseline in whom weight loss will be evaluated. Sufficient numbers of participants in both groups will be recruited to evaluate these outcomes. Secondary and exploratory aims of the study will be to examine other health related outcomes and process measures related to intervention use and satisfaction. RELEVANCE (See instructions): Overweight/obesity are highly prevalent conditions in the US impacting approximately 66% of the adult population. Reducing the overall incidence of obesity is a major public health concern, yet little is known about how to do this with young adults. This study will address this gap in knowledge. (End of Abstract)
