Using Technology to Prevent Obesity Among African American Girls

描述（由申请人提供）：本研究将对8-10岁非裔美国女孩的基于网络的肥胖预防计划进行结果评估。一项针对80名女孩的试点研究确定了其可行性：达到了招募目标;流失率<10%;在线计划的登录率为74.5%;观察到水果和蔬菜消费量以及体力活动时间在统计学上显著增加。结果评估将招募400名儿童-父母对，以检查该计划对肥胖风险的短期和长期影响。它还将进行调解分析，以审查影响途径。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改变健康行为的方法并不新鲜，但单独使用互联网程序，没有面对面的互动，是新颖的。这是第一个尝试这样做的项目，特别是在高危人群中。 公共卫生相关性：该项目的目的是减少8-10岁非裔美国女孩肥胖风险的健康差异，使用文化敏感和发展适当的基于互联网的计划，没有面对面的互动。这项研究将进行结果评估，以测试对肥胖风险的短期和长期影响。

DESCRIPTION (provided by applicant): 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. PUBLIC HEALTH RELEVANCE: The purpose of this project is to reduce health disparities in obesity risk among 8-10 year old African American girls using a culturally sensitive and developmentally appropriate internet-based program with no face-to-face interaction. This study will conduct an outcome evaluation to test short and longer term effects on obesity risk.
