The role of social support in bariatric surgery weight and behavioral outcomes

描述(由申请者提供)：超过500万美国人患有极端肥胖(BMI E 40)。减肥手术是目前治疗极端肥胖的最有效的长期治疗方法；然而，关于减肥结果与社会心理因素(如社会支持)之间的关系的研究喜忧参半，而且没有定论。拟议的奖学金将前瞻性和系统地评估社会支持在减肥手术后减肥、坚持饮食和生活方式改变以及减肥手术后健康行为结果方面的作用，这些患者主要是非洲裔美国人和低收入患者(N=55)，这些群体受到肥胖和相关疾病的不成比例影响。手术前基线和术后6个月的结果测量包括体重，以及对体力活动、饮食行为、依从性和食物摄入频率的自我报告评估。假设1)健康相关社会支持增加越多，术后6个月体重下降越大；2)一般社会支持增加越多，术后6个月体重减轻越大；3)健康相关社会支持增加越多，术后6个月健康行为和坚持性改善越大；4)一般社会支持增加越多，术后6个月健康行为改变越大，坚持越多。二次分析将评估与健康有关的社会支持的具体方面(即饮食和锻炼)和一般社会支持(即结构或功能)与手术后结果之间的关系。评估社会支持在减肥手术中的作用提供了一个机会，以确定肥胖干预的新目标，以帮助改善 减肥手术患者的治疗。

DESCRIPTION (provided by applicant): Over five million Americans live with extreme obesity (BMI e 40). Bariatric surgery is currently the most effective long-term treatment for extreme obesity; however, research regarding the relationship between bariatric outcomes and psychosocial factors such as social support is mixed and inconclusive. The proposed fellowship will prospectively and systematically assess the role of social support in weight loss, adherence to diet and lifestyle changes, and health behavior outcomes following bariatric surgery in a predominantly African American and low income patient population (N=55), groups disproportionately impacted by obesity and related conditions. Outcome measures at pre-operative baseline and 6-months post-operatively include weight, as well as self-report assessments of physical activity, eating behaviors, adherence and food intake frequency. Hypotheses posit that 1) greater increases in health-related social support will be associated with greater weight loss 6-months post-operatively; 2) greater increases in general social support will be associated with greater weight loss 6-months post-operatively; 3) greater increases in health-related social support will be associated with greater improvements in health behaviors and adherence 6-months post- operatively; and 4) greater increases in general social support will be associated with greater health behavior changes and adherence 6-months post-operatively. Secondary analyses will evaluate the relationship between specific aspects of health-related social support (i.e., diet and exercise) and general social support (i.e., structura or functional) and post-operative outcomes. Evaluating the role of social support in bariatric surgery provides an opportunity to identify novel targets for obesity interventions to help improve the treatment of bariatric surgery patients.
