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

描述（由申请人提供）：超过500万美国人患有极度肥胖症（BMI e 40）。减肥手术是目前最有效的长期治疗极端肥胖;然而，关于减肥结果与社会心理因素（如社会支持）之间关系的研究是混合的，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，坚持饮食和生活方式改变，以及减肥手术后的健康行为结果中的作用，主要是非洲裔美国人和低收入患者人群（N=55），受肥胖和相关疾病影响不成比例的群体。术前基线和术后6个月的结局指标包括体重，以及身体活动、饮食行为、依从性和食物摄入频率的自我报告评估。假设：1）健康相关社会支持的增加与术后6个月的体重减轻相关; 2）一般社会支持的增加与术后6个月的体重减轻相关; 3）健康相关社会支持的增加与术后6个月的健康行为和依从性的改善相关; 4）一般社会支持的增加与术后6个月的健康行为改变和依从性相关。次要分析将评估与健康相关的社会支持的特定方面（即，饮食和锻炼）和一般社会支持（即，结构或功能）和术后结果。评估社会支持在减肥手术中的作用为确定肥胖干预的新目标提供了机会， 减肥手术患者的治疗。 公共卫生相关性：拟议的研究有可能为肥胖干预提供新的目标。此外，拟议研究的结果可能会被应用于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. PUBLIC HEALTH RELEVANCE: The proposed research has the potential to provide novel targets for obesity interventions. Further, findings of the proposed study may be applied to improve treatment of bariatric surgery patients.
