This study describes the development and usage of a Web-based component of a nutrition and physical activity behavioral intervention to promote bone health among preadolescent girls. Thirty Girl Scout troops were randomized to either an intervention or control group for a 2-year period. Girls in the intervention troops (aged 10 to 12 years, N=194) were exposed to grade-specific Web sites that were developed to reinforce the content of the broader, face-to-face intervention. In 5th grade, 82% of the girls logged on once and 48% logged on more than once, compared to 56% and 23% of 6th graders, respectively. Results suggest that although Web-site usage decreased over time, a Web-site program may be useful as a component of a face-to-face, multicomponent intervention. More research is needed to determine ways to enhance and maintain Web-site use over time among youth in health-behavior intervention programs.
本研究描述了一种基于网络的营养与身体活动行为干预组件的开发与使用情况，该干预旨在促进青春期前女孩的骨骼健康。30个女童军小队被随机分为干预组或对照组，为期2年。干预组的女孩（年龄在10至12岁，N = 194）可以访问专门为强化更广泛的面对面干预内容而开发的特定年级网站。五年级时，82%的女孩登录过一次，48%的女孩登录过不止一次，而六年级女孩的这两个比例分别为56%和23%。结果表明，尽管网站使用随时间减少，但网站程序作为面对面多组件干预的一个组成部分可能是有用的。需要更多研究来确定如何在健康行为干预项目中随着时间的推移增强和维持青少年对网站的使用。
