Multi-media Obesity Prevention Program for Adolescents

描述(申请人提供)：肥胖被认为是一个主要的公共卫生问题，并已成为国家卫生优先事项。随着青少年肥胖率几乎是20年前的三倍，需要采取有效的干预措施来预防和治疗青少年超重和肥胖。通过具有成本效益、基于科学和易于交付的干预措施来加强与肥胖预防相关的健康行为的计划可以是帮助遏制儿童超重和肥胖率的有效解决方案。本研究的目的是为高中生开发和测试基于跨理论模型的干预措施，以促进与预防肥胖相关的健康行为的采用和维持。我们第一阶段项目的成功完成表明，一个阶段匹配的多媒体专家系统既可以为高中生所接受，也可以在高中环境下进行。我们第二阶段应用的主要目标是完成专家系统干预的开发，并在随机临床试验中评估其有效性。有效性将通过比较随机分配到干预或控制条件下的高中生的水果和蔬菜摄入量、体力活动、看电视和几个次要结果指标来评估。

DESCRIPTION (provided by applicant): Obesity is recognized as a major public health concern and has become a national health priority. With the prevalence of adolescent obesity nearly triple what it was two decades ago, effective interventions to prevent and treat overweight and obesity among adolescents are needed. Programs to enhance the healthy behaviors related to obesity prevention with cost-effective, science-based and easily deliverable interventions can be effective solutions to help curb the rate of childhood overweight and obesity. The objective of this research is to develop and test a Transtheoretical Model-based intervention for high school students that promotes the adoption and maintenance of healthy behaviors related to the prevention of obesity. The successful completion of our Phase I project demonstrates that a stage-matched, multi-media expert system is both acceptable to high school students and feasible to conduct in a high school setting. The primary goals of our Phase II application are to complete the development of the expert system intervention and to assess its effectiveness in a randomized clinical trial. Effectiveness will be assessed by comparing fruit and vegetable consumption, physical activity, TV watching, and several secondary outcome measures among high school students randomly assigned to the intervention or control condition.
