"Food Resource Equity and Sustainability for Health" or "FRESH"

 描述（申请人提供）：背景：食物不安全增加肥胖、糖尿病、高血压和癌症的风险。俄克拉荷马州的美洲印第安人（AI）的食物不安全率是白人的三倍（21%对7%），肥胖率（42%），高血压（38%）和糖尿病（15%）的负担超过了美国普通人口。虽然个人层面的肥胖预防工作已经与人工智能实施，很少有环境干预措施，以减少粮食不安全和改善水果和蔬菜的摄入量已与部落社区进行。社区园艺干预措施已被证明可以增加蔬菜和水果的摄入量，减少食品不安全，降低儿童和成人的BMI;然而，迄今为止，还没有对AI家庭进行过此类干预措施的评估。这项名为“食物公平资源和健康可持续性”的拟议研究将评估部落发起的社区园艺干预对生活在俄克拉荷马州奥萨奇民族保留地的家庭的蔬菜和水果摄入量、食物不安全、BMI和血压的影响。干预将在奥塞奇国家的鸟溪农场和社区花园，其中120个花园地块将分配给参与保留家庭的第一年。该研究以社区参与性研究（CBPR）和土著粮食主权运动的原则为指导，旨在振兴季节性种植和采集做法，扭转部落土地历史损失造成的不健康饮食趋势。目的和方法：由AI（乔托）研究员领导，该研究将：目标#1：通过使用客观和感知的措施来描述奥萨奇民族保留地的食品环境，然后检查这些措施与蔬菜和水果的摄入量，食品不安全，BMI，高血压和糖尿病之间的关系。目标二：制定一个文化相关的社区园艺干预措施，并进行随机对照试验（RCT），以评估其在增加蔬菜和水果摄入量，减少粮食不安全，体重指数和血压的Osage家庭的有效性。目标3：制作和传播网络多媒体手册和纪录片，并评价其在提高部落改善当地粮食环境的准备和能力方面的效力。创新：这项拟议的研究将是有史以来第一次进行社区园艺干预的随机对照试验，也是第一次对人工智能家庭进行社区园艺干预。该研究也将是第一个环境干预措施之一，同时解决健康食品的生产，获取，偏好和摄入量。意义和影响：社区园艺干预措施将作为一个更大的奥塞奇国家粮食安全和粮食主权倡议的一部分，因此，如果证明有效，很可能是可持续的。研究结果和产品将传播到全国的人工智能/人工智能社区，并将有助于确定环境战略，改善部落的食物环境和人工智能家庭的健康和生活质量。

 DESCRIPTION (provided by applicant): Background: Food insecurity increases the risk of obesity, diabetes, hypertension, and cancer. American Indians (AIs) in Oklahoma are three times as likely as Whites to be food-insecure (21% vs. 7%) and have burdens of obesity (42%), hypertension (38%), and diabetes (15%) that exceed those of the general US population. While individual-level obesity prevention efforts have been implemented with AIs, few environmental interventions to reduce food insecurity and improve fruit and vegetable intake have been conducted with tribal communities. Community gardening interventions have been shown to increase vegetable and fruit intake, reduce food insecurity, and lower BMI among children and adults; however, to date, no such interventions have been evaluated with AI families. The proposed study, entitled "Food Equity Resource and Sustainability for Health (FRESH)," will assess the impact of a tribally-initiated community gardening intervention on vegetable and fruit intake, food insecurity, BMI, and blood pressure in families living on the Osage Nation reservation in Oklahoma. The intervention will take place in the inaugural year of Osage Nation's Bird Creek Farm and Community Gardens, where 120 garden plots will be allocated to participating reservation families. The study is guided by the principles of community-based participatory research (CBPR) and the Indigenous food sovereignty movement, which seeks to revitalize seasonal growing and gathering practices and reverse the tide of unhealthy eating caused by the historical loss of tribal lands. Aims and Methods: Led by an AI (Choctaw) Investigator, the study will: Aim #1: Characterize the Osage Nation reservation's food environment by using both objective and perceived measures, and then examine the relationships between these measures and intake of vegetables and fruits, food insecurity, BMI, hypertension, and diabetes. Aim #2: Develop a culturally relevant community gardening intervention and conduct a randomized controlled trial (RCT) to evaluate its efficacy in increasing vegetable and fruit intake and reducing food insecurity, BMI, and blood pressure among Osage families. Aim #3: Create and disseminate a Web- based multimedia manual and documentary film, and evaluate their effectiveness in increasing tribal readiness and capacity to improve local food environments. Innovation: The proposed study will be the first RCT ever conducted of a community gardening intervention, as well as the first community gardening intervention with AI families. The study will also be one of the first environmental interventions o simultaneously address healthy food production, access, preference, and intake among AIs. Significance and Impact: The community gardening intervention will be developed as part of a larger Osage Nation initiative on food security and food sovereignty and as such, is likely to be sustainable if it proves effective. Research findings and products will be disseminated to AI/AN communities nationwide and will help to identify environmental strategies that will improve tribal food environments and the health and quality of life of AI families.
