Using Technology to Prevent Obesity Among African American Girls

描述(由申请者提供)：这项研究将对一个有前景的基于网络的8-10岁非裔美国女孩肥胖预防计划进行结果评估。一项对80名女孩进行的初步研究确定了它的可行性：招募目标实现了；流失率为10%；在线计划的登录率为74.5%；从统计上看，水果和蔬菜的消费量以及从事体育活动的时间都有显著增加。结果评估将招募400对父母和孩子来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，以审查产生效果的途径。在研究结束时，基于网络的方案将放在CNRC网站上。尽管使用互联网作为一种改变健康行为的方法并不新鲜，但仅使用互联网程序，而不是面对面的互动，是新的。这是首批尝试这样做的项目之一，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岁非裔美国女孩在肥胖风险方面的健康差异，使用基于互联网的文化敏感和适合发展的计划，而不是面对面的互动。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.
