背景：随着肥胖率的上升，需要新的减肥方法。人们对播客的使用知之甚少设计：一项为期12周的随机对照试验。设置/参与者：研究样本包括超重的男性和女性（BMI=25-40 kg/m（2）; n=78）在罗利-达勒姆北卡罗来纳州地区。2008年，参与者被随机分配接受24集当前可用的减肥播客（对照播客）或由研究人员设计的基于社会认知理论（SCT）的减肥播客（增强播客）持续12周。主要结果测量：在基线和随访时在数字秤上测量体重。两组还在介绍性会议和12周会议上完成了评估人口统计学信息、食物摄入量、体力活动和SCT结构的问卷。额外的问卷调查在12周的会议评估的intervention.Results的看法：数据收集和分析发生在2008年和意向治疗。增强组参与者（n=41）的体重下降幅度更大（增强组-2.9+/-3.5 kg vs对照组-0.3+/-2.1 kg; p
Background: As obesity rates rise, new weight-loss methods are needed. Little is known about the use of podcasting (audio files for a portable music player or computer) to promote weight loss, despite its growing popularity.Design: A 12-week RCT was conducted.Setting/participants: The study sample comprised overweight men and women (BMI=25-40 kg/m(2); n=78) in the Raleigh-Durham NC area.Intervention: In 2008, participants were randomly assigned to receive 24 episodes of a currently available weight-loss podcast (control podcast) or a weight-loss podcast based on social cognitive theory (SCT) designed by the researchers (enhanced podcast) for 12 weeks.Main outcome measures: Weight was measured on a digital scale at baseline and follow-up. Both groups also completed questionnaires assessing demographic information, food intake, physical activity, and SCT constructs at the introductory and 12-week meetings. Additional questionnaires at the 12-week meeting assessed perceptions of the intervention.Results: Data collection and analysis occurred in 2008 and intention-to-treat was used. Enhanced group participants (n=41) had a greater decrease in weight (-2.9+/-3.5 kg enhanced group vs -0.3+/-2.1 control group; p
