Using Technology to Prevent Obesity Among African American Girls

项目摘要 本研究将对一种有前景的基于网络的肥胖预防进行结果评估 为8-10岁的非洲裔美国女孩提供的项目。一项针对80名女孩的试点研究建立了 可行性：达到招聘目标;流失率<10%;在线登录率 74.5%;水果和蔬菜消费量在统计学上显著增加 和体力活动时间。成果评价将招募400名 儿童-父母配对，以检查该计划对肥胖风险的短期和长期影响。它将 并进行调解分析，以审查影响的途径。在研究结束时， 基于网络的程序将在CNRC网站上托管。虽然使用互联网作为一个 改变健康行为的方法并不新鲜，仅仅使用互联网程序， 面对面的互动，是新奇的。这是第一个尝试这一点的程序之一，特别是在 处于危险中的人群。

PROJECT SUMMARY This research will conduct an outcome evaluation on a promising web based obesity prevention program for 8-10 year old African American girls. A pilot study with 80 girls established its feasibility: recruitment goals were met; attrition rates were <10%; logon rates to the online program were 74.5%; and statistically significant increases in fruit and vegetable consumption and time spent being physically active were observed. The outcome evaluation will recruit 400 child-parent pairs to examine short and longer term effects of the program on obesity risk. It will also conduct mediation analyses to examine pathways of effect. At the end of the study, the web based program will be hosted on the CNRC web site. Although the use of the internet as a method for changing health behavior is not new, the use of an internet program alone, with no face to face interaction, is novel. This is one of the first programs to attempt this, particularly in an at-risk population.
