Nutrltlon & Physical Activity Core

对饮食和身体活动的有效评估具有独特的挑战性，需要专门的科学方法， 专业知识、创造力和高水平的员工培训。CANHR的营养和身体活动的目的 (NPA)核心是促进需要饮食和/或体力活动评估的跨学科研究 和干预。NPA核心支持饮食和身体活动评估的所有方面，包括 选择和/或修改适当的评估方法，制定质量控制程序，以及 指导对结果数据的分析和解释。我们已经培训了一批调查人员，工作人员， 和学生收集和处理饮食摄入数据。我们将继续提供这些服务， CANHR正在从观察性研究转向干预性研究，我们建议将我们的服务扩展到 包括编制营养和体育活动教育材料，以支持干预科学。 NPA核心的独特和至关重要的方面是它在调整内容，设计和 管理饮食和身体评估工具，用于阿拉斯加土著社区。标准 营养和体力活动评估方法在文化和社会领域缺乏相关性和有效性， 地理上独特的阿拉斯加原住民背景。对稳定的NPA核心的持续支持将导致 加速和长期增长的营养和身体活动的研究在CANHR和可持续性 这一重要的核心资源。 在这方面，《国家行动计划》核心的具体目标是： 具体目标1。提供和支持有效的和文化上适当的最先进的饮食和身体 活动评估方法。 具体目标2。发展和提供文化上适当的营养和体育活动教育 支持营养和身体活动干预科学的材料。 具体目标3。培训CANHR研究人员和工作人员使用营养和身体活动核心 资源

Valid assessment of diet and physical activity is uniquely challenging, requiring specialized scientific expertise, creativity and high levels of staff training. The purpose of CANHR's Nutrition and Physical Activity (NPA) Core is to facilitate interdisciplinary research requiring dietary and/or physical activity assessment and intervention. The NPA Core supports all aspects of dietary and physical activity assessment, including selecting and/or modifying appropriate assessment methods, developing quality control procedures, and guiding the analysis and interpretation of the resulting data. We have trained a cadre of investigators, staff, and students to collect and process diet intake data. We will continue providing these services and, as CANHR is moving from observational to intervention research, we propose to expand our services to include developing nutrition and physical activity education materials to support intervention science. The unique and critically important aspect of the NPA Core is its role in adapting the content, design and administration of dietary and physical assessment tools for use in Alaska Native communities. Standard approaches to nutrition and physical activity assessment lack relevance and validity within the culturally and geographically unique Alaska Native context. Continued support for a stable NPA Core will result in an accelerated and long-term growth of nutrition and physical activity research in CANHR and sustainability of this important core resource. Wthin this context, the specific aims of the NPA Core are: Specific Aim 1. To provide and support valid and culturally appropriate state-of-the-art dietary and physical activity assessment methods. Specific Aim 2. To develop and provide culturally appropriate nutrition and physical activity education materials in support of nutrition and physical activity intervention science. Specific Aim 3. To train CANHR investigators and staff in the usage of Nutrition and Physical Activity Core resources.
