A prospective examination of sleep, eating behavior, and weight gain among overweight adults PROJECT SUMMARY/ABSTRACT Approximately 70% of American adults are overweight or obese, which confers increased risk for reduced quality of life, disability, chronic disease, and mortality. Efforts to reduce the public health burden of obesity have identified bio-behavioral factors involved in the development and maintenance of high body weight. Sleep has emerged as a particularly robust predictor of weight gain and obesity in both prospective and cross- sectional research, but the mechanisms linking sleep and weight gain have not been adequately defined. The purpose of the proposed study is to examine actigraphy-assessed sleep duration as a prospective predictor of binge eating behavior and the extent to which binge eating mediates the relationship between sleep duration and weight gain and body composition over one year among overweight and obese adults. Further, executive function (I.e., inhibitory control, working memory, set-shifting, planning, decision making) as measured by a neurocognitive task battery will be examined as a moderator in the relationship between sleep and binge eating. As short sleep duration is associated with deficits in executive function, we hypothesize that higher trait levels of executive function will attenuate the effect of short sleep duration on binge eating. Achievement of our study aims will provide novel insight into the role of disordered eating behavior as a mechanism linking sleep and obesity and elucidate the extent to which executive function may affect sleep’s impact on eating behavior and weight gain. The knowledge gained from this study has the potential to inform obesity prevention or intervention efforts and identify vulnerable individuals which allows for more strategic allocation of public health resources.

对超重成年人的睡眠、饮食行为和体重增加的前瞻性检查 项目概要/摘要 大约 70% 的美国成年人超重或肥胖，这增加了体重下降的风险 生活质量、残疾、慢性病和死亡率的努力。 已经确定了与高体重的发展和维持有关的生物行为因素。 在前瞻性和交叉研究中，睡眠已成为体重增加和肥胖的特别有力的预测因素。 部门研究，但睡眠和体重增加之间的联系机制尚未得到充分定义。 拟议研究的目的是检查体动记录仪评估的睡眠持续时间作为睡眠持续时间的前瞻性预测因素 暴食行为以及暴食在多大程度上介导睡眠时间之间的关系 超重和肥胖成年人一年内的体重增加和身体成分。 功能（即抑制控制、工作记忆、设定转移、计划、决策） 神经认知任务电池将作为睡眠和暴饮暴食之间关系的调节因素进行检查 由于睡眠时间短与执行功能缺陷有关，我们已经捕捉到了这一更高的特征。 执行功能水平会减弱短睡眠时间对暴饮暴食的影响。 我们的研究目的是对饮食失调行为作为联系机制的作用提供新的见解。 睡眠和肥胖，并阐明执行功能可能影响睡眠对饮食的影响程度 从这项研究中获得的知识有可能为肥胖的预防提供信息。 或干预措施并识别弱势个体，以便对公共资源进行更具战略性的分配 卫生资源。
