Using Technology to Prevent Obesity Among African American Girls

项目总结 这项研究将对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而设的项目。一项针对80名女孩的初步研究确立了它的 可行性：达到招聘目标；流失率为10%；在线登录率 74.5%；水果和蔬菜消费量在统计上有显著增长 并观察进行体力活动的时间。结果评估将招募400人 孩子-父母对检查该计划对肥胖风险的短期和长期影响。会的 还要进行调解分析，以检查效果的途径。在研究结束时， 基于网络的节目将在CNRC网站上托管。尽管使用互联网作为一种 改变健康行为的方法并不新鲜，单独使用互联网程序，没有 面对面的互动，是新奇的。这是首批尝试这样做的程序之一，特别是在 高危人群。

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.
