Assessing African American Adolescent Food Intakes

描述(由申请人提供)： SBIR第二阶段将全面开发和验证健康饮食自我监测工具(HEST)，这是一种以光盘为媒介的食品记录，用于衡量11至14岁经济困难的黑人青少年的水果和蔬菜消费量。根据第一阶段的结果数据和当前饮食评估的最佳实践，第二阶段将记录本研究第一阶段开发的原型HEST的计划修订。计划中的修订将由一个具有饮食评估专业知识的专业小组和代表目标人群的青少年重点群体进行审查。这些参照人提供的反馈将为充分制定该措施的计划提供依据。将对完全开发的HEST进行编程，以便通过CD-ROM进行传递。 在随机重复测量对照组设计中，将检查通过3天食物记录测量的HEST相对实际摄入量和摄入量的表现。通过大纽约市的社会服务机构招募的300名知情和同意的年轻人样本将被随机分配到实验和对照研究小组。每组参与者将在连续三天的时间内获得早餐、午餐和晚餐。用餐后，接受实验的青少年将使用Hest记录他们的水果和蔬菜消费量。控制手臂的青少年将使用3天的食物记录来记录他们的摄入量。青少年提供的数据将被用来建立HEST的标准相关和趋同效度以及重测信度。如果第二阶段被证明是成功的，第三阶段将需要向学校和社会服务机构(如参与这项研究和开发工作的机构)传播HEST。这项全面开发的措施旨在将其用作健康促进计划中的自我监测工具，旨在增加经济困难的黑人青少年的水果和蔬菜消费。

DESCRIPTION (provided by applicant): This Phase II SBIR will fully develop and validate the Healthy Eating Self-Monitoring Tool (HEST), a CD-ROM-mediated food record for measuring fruit and vegetable consumption among economically disadvantaged Black adolescents aged 11 though 14 years. Drawing from Phase I outcome data and current best practices in dietary assessment, Phase II will document planned revisions to the prototype HEST developed in Phase I of this research. Planned revisions will undergo review by a panel of professionals with expertise in dietary assessment and focus groups of adolescents, representative of the target population. Feedback provided by these referents will inform plans to fully develop the measure. The fully developed HEST will be programmed for CD-ROM-mediated delivery. In a randomized repeated measures control-group design, the performance of the HEST relative tactual intake and intake measured via 3-day food records will be examined. Recruited through social service agencies across greater New York City, a sample of 300 informed and consenting youths will be randomized to experimental and control study arms. Groups of participants will be served breakfast, lunch, and dinner meals over a consecutive 3-day period. Following meals, experimental-arm youths will record their fruit and vegetable consumption using the HEST. Control-arm youths will record their intakes using 3-day food records. Data provided by youths will be used to establish the criterion-related and convergent validity and test-retest reliability of the HEST. Should Phase II prove successful, Phase III will entail dissemination of the HEST to schools and social service agencies such as those participating in this research and development effort. The fully developed measure is intended for use as a self-monitoring tool in health promotion programs designed to increase fruit and vegetable consumption among economically disadvantaged Black adolescents.
