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

 描述(由申请人提供)：背景：食物不安全会增加肥胖、糖尿病、高血压和癌症的风险。俄克拉何马州的美国印第安人(AIS)食物不安全的可能性是白人的三倍(21%比7%)，他们的肥胖(42%)、高血压(38%)和糖尿病(15%)的负担超过了普通美国人。虽然已经与人工智能机构一起实施了个人一级的肥胖预防努力，但在部落社区中几乎没有采取环境干预措施，以减少粮食不安全和改善水果和蔬菜的摄入量。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，减少儿童和成年人的食物不安全，并降低体重指数；然而，到目前为止，还没有对人工智能家庭进行这种干预措施的评估。这项名为《食品公平资源与健康可持续发展(Fresh)》的拟议研究将评估由部落发起的社区园艺干预措施对生活在俄克拉荷马州奥萨奇民族保留区的家庭的蔬菜和水果摄入量、食物不安全、体重指数和血压的影响。干预活动将在奥萨奇国家鸟溪农场和社区花园成立的第一年进行，届时将有120块园地分配给参与保留的家庭。这项研究的指导原则是基于社区的参与性研究(CBPR)和土著粮食主权运动，该运动旨在振兴季节性种植和采集做法，扭转因部落土地历史丧失而导致的不健康饮食趋势。目标和方法：由人工智能(Choctaw)调查员领导的这项研究将：目标1：通过客观和感知的措施来描述奥萨奇民族保留地的食物环境，然后检查这些措施与蔬菜和水果的摄入量、食物不安全、BMI、高血压和糖尿病之间的关系。目的#2：开发与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、降低食物不安全、体重指数和血压方面的效果。目标3：制作和传播基于网络的多媒体手册和纪录片，并评估其在提高部落准备和能力以改善当地食物环境方面的有效性。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。这项研究也将是首批同时解决认可机构健康食品生产、获取、偏好和摄取的环境干预措施之一。意义和影响：社区园艺干预措施将作为关于粮食安全和粮食主权的更大的奥萨奇国家倡议的一部分而发展，因此，如果证明有效，很可能是可持续的。研究成果和产品将传播到全国人工智能/人工智能社区，并将有助于确定将改善部落食物环境以及人工智能家庭的健康和生活质量的环境战略。

 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.
