The purpose of this study was to develop and evaluate a 12-week weight management intervention involving computerized self-monitoring and technology-assisted feedback with and without an enhanced behavioral component.
120 overweight (30.5±2.6kg/m(2)) adults (45.0±10.3 years) were randomized to one of three groups: computerized self-monitoring with Basic feedback (n=45), Enhanced behavioral feedback (n=45), or wait-list control (n=30). Intervention participants used a computer software program to record dietary and physical activity information. Weekly e-mail feedback was based on computer-generated reports, and participants attended monthly measurement visits.
The Basic and Enhanced groups experienced significant weight reduction (-2.7±3.3kg and -2.5±3.1kg) in comparison to the Control group (0.3±2.2; p<0.05). Waist circumference and systolic blood pressure also decreased in intervention groups compared to Control (p<0.01).
A program using computerized self-monitoring, technology-assisted feedback, and monthly measurement visits produced significant weight loss after 12 weeks. However, the addition of an enhanced behavioral component did not improve the effectiveness of the program.
This study suggests that healthcare professionals can effectively deliver a weight management intervention using technology-assisted strategies in a format that may complement and reduce face-to-face sessions.
本研究旨在开发并评估一项为期 12 周的体重管理干预措施，包括计算机化自我监测和技术辅助反馈，以及是否增加强化行为成分。
120 名超重（30.5±2.6kg/m²）成年人（45.0±10.3 岁）被随机分为三组：基本反馈的计算机化自我监测组（n=45）、增强型行为反馈组（n=45）或候补对照组（n=30）。干预组参与者使用计算机软件程序记录饮食和身体活动信息。每周通过电子邮件反馈基于计算机生成的报告，参与者每月参加测量访问。
与对照组（0.3±2.2kg）相比，基本组和增强组的体重明显减轻（-2.7±3.3kg 和-2.5±3.1kg）（p<0.05）。与对照组相比，干预组的腰围和收缩压也有所下降（p<0.01）。
使用计算机化自我监测、技术辅助反馈和每月测量访问的方案在 12 周后可显著减轻体重。然而，增加强化行为成分并没有提高该方案的效果。
本研究表明，医疗保健专业人员可以有效地使用技术辅助策略提供体重管理干预措施，这种方式可能补充并减少面对面的就诊次数。
