Young African American girls have a high risk of obesity. Online behavior change programs promoting healthy diet and physical activity are convenient and may be effective for reducing disparities related to obesity. This report presents the protocol guiding the design and evaluation of a culturally and developmental appropriate online obesity prevention program for young African American girls.
METHODS/DESIGN: The Butterfly Girls and the Quest for Founder's Rock is an 8-episode online program delivered as an animated, interactive comic. The program promotes healthy diet and physical activity and is specifically designed for 8-10 year old African American girls. Girls, parents, and community representatives provided formative feedback on cultural relevance and developmental appropriateness. A three-group (treatment, comparison, wait-list control) randomized design (n=390 parent/child dyads) is employed, with child as the unit of assignment. Change in body mass index is the primary outcome; change in fruit and vegetable consumption, water, and physical activity are secondary outcomes. Data collection occurs at baseline, approximately 3 months after baseline (i.e., completion of the online program), and approximately three months later (i.e., maintenance assessment). Two dietary recalls are collected at each data collection period by trained interviewers using the Nutrient Data System for Research (NDSR 2012) system. Physical activity is objectively measured by seven days of accelerometry. Psychosocial and process data are also collected. Girls in the treatment and comparison groups will be interviewed at post 1 to obtain information on personal reactions to the program.
This research will develop and evaluate the efficacy of an online program for reducing obesity risk among girls at risk of obesity and related diseases. Online programs offer the potential for wide dissemination, thus reducing disparities related to obesity.

年轻的非裔美国女孩肥胖风险较高。促进健康饮食和体育活动的在线行为改变项目便捷，可能有助于减少与肥胖相关的差异。本报告介绍了一项针对年轻非裔美国女孩的、在文化和发育方面适宜的在线肥胖预防项目的设计与评估方案。
方法/设计：《蝴蝶女孩与寻找创始人之石》是一个8集的在线项目，以动画互动漫画的形式呈现。该项目促进健康饮食和体育活动，专为8至10岁的非裔美国女孩设计。女孩、家长和社区代表就文化相关性和发育适宜性提供了形成性反馈。采用三组（治疗组、对照组、等待名单对照组）随机设计（n = 390对亲子），以儿童为分配单位。体重指数的变化是主要结果；水果和蔬菜摄入量、饮水量以及体育活动的变化是次要结果。数据收集在基线、基线后约3个月（即在线项目完成时）以及约3个月后（即维持评估）进行。在每个数据收集期，由经过培训的访谈员使用研究用营养数据系统（NDSR 2012）收集两次饮食回忆。通过七天的加速度计客观测量体育活动。还收集心理社会和过程数据。治疗组和对照组的女孩将在第1阶段后接受访谈，以获取她们对该项目个人反应的信息。
本研究将开发并评估一个在线项目在降低肥胖及相关疾病风险女孩肥胖风险方面的疗效。在线项目具有广泛传播的潜力，从而减少与肥胖相关的差异。
