 DESCRIPTION (provided by applicant): Project Summary/Abstract National data show that 82% of African American (AA) women are overweight or obese, and 57% are obese. The health risks associated with the high prevalence of overweight and obesity among AA women is concerning, as these risks contribute to subsequent chronicities including cardiovascular disease (CVD) and type 2 diabetes (T2D). Physical activity (PA) is an established mechanism to manage weight and to improve myriad cardiometabolic disease risk factors. However, despite these benefits, only 36% of AA women meet the national PA guidelines. The low PA levels among AA women coupled with the high prevalence of overweight/obesity and other chronic disease conditions indicate the need for effective strategies to promote sustained high PA in this high-risk population. Technology-based platforms (i.e. Smartphone applications, Internet, social media) represent potential channels to deliver PA interventions to AA women. However, few researchers have explored these platforms to deliver culturally relevant PA interventions to AA women. This represents a missed opportunity given the established success of technology-delivered behavior change interventions and data suggesting that AA women use Internet, social media, and Smartphones at equal or greater rates than other race/ethnic groups. Over the past 5 years, the applicant of this proposed work has focused on filling this gap in the published research through the development and evaluation of technology-based approaches to increase PA among AA women. Trained as a behavioral scientist, his graduate and postdoctoral training has been focused in the social and psychological sciences, with a particular emphasis on the development and evaluation of theory- driven, culturally relevant technology-based PA interventions for AA women. The research and training proposed in the current application will extend and refine the candidate's PA and health disparities research trajectory through : 1) focused training in the physiological and biochemical mechanisms underpinning cardiometabolic disease risk factors responsive to PA intervention, and 2) evaluation of the effects of a culturall relevant Smartphone-delivered PA program (Smart Walk) to improve (baseline to 6 months) and maintain (7 months to 12 months) higher PA levels among AA women and improve cardiometabolic disease risk factors. The candidate has identified a supportive and stimulating research environment at Arizona State University to pursue the proposed research. Under the mentorship and Drs. Barbara Ainsworth, Colleen Keller, Glenn Gaesser, and Sonia Vega-Lopez, he will gain the necessary skills to establish himself as an independent behavioral and health disparities research scientist. In the K99 portion of the grant award, the applicant will gan explicit training in the physiological and biochemical mechanisms underpinning cardiometabolic disease risk factors responsive to PA intervention through didactic coursework and hands-on clinical laboratory experience. Training in this research area will complement his already strong social science background by allowing him to gain a deeper understanding of the physiological mechanisms associated with the health-enhancing benefits of PA. In the R00 phase of the grant award, the applicant will deploy the training acquired during the K99 phase and build logically upon his previous health disparities research trajectory by implementing a 12-month technology-based PA randomized controlled trial to evaluate the effects of a culturally relevant Smartphone-delivered PA intervention to improve (baseline to 6 months) and maintain (7 months to 12 months) high PA levels and reduce cardiometabolic disease risk among obese AA women. Seventy-six obese AA women will receive either a culturally relevant, Social Cognitive Theory-based PA promotion program delivered using a Smartphone application or a wellness contact control condition. PA, fitness, and cardiometabolic disease risk factors will be evaluated. Potential physiological mechanisms through which PA may impact cardiometabolic disease risk factors will also be explored. The proposed research and training activities support the immediate and long-term career goals of the applicant. The applicant's immediate career goal is to enhance his theory based PA research to include salient mechanisms that underpin PA effects on health (i.e. inflammation), towards the prevention and treatment of cardiometabolic disease risk factors among AA women. His long-term career goals are to: a) establish an independent, externally-funded program of research focused on the identification of effective strategies to promote sustained PA among racial/ethnic minorities, and 2) reduce the disproportionate burden of the cardiometabolic diseases among high-risk minority populations. The training and research activities proposed in the current K99/R00 application will assist the candidate in achieving these career goals, and advance PA and health disparities science.

 描述（由申请人提供）：项目摘要/摘要 国家数据显示，82% 的非裔美国 (AA) 女性超重或肥胖，其中 57% 为肥胖。 AA 女性中超重和肥胖率高所带来的健康风险令人担忧，因为这些风险会导致随后的慢性病，​​包括心血管疾病 (CVD) 和 2 型糖尿病 (T2D)。体力活动（PA）是控制体重和改善多种心脏代谢疾病危险因素的既定机制。然而，尽管有这些好处，只有 36% 的 AA 女性符合国家 PA 指南。 AA 女性的 PA 水平较低，加上超重/肥胖和其他慢性疾病的高患病率，表明需要采取有效的策略来促进这一高危人群的持续高 PA 水平。基于技术的平台（即智能手机应用程序、互联网、社交媒体）是向 AA 女性提供 PA 干预的潜在渠道。然而，很少有研究人员探索这些平台，为 AA 女性提供文化相关的 PA 干预措施。鉴于技术提供的行为改变干预措施已取得成功，并且数据表明 AA 女性使用互联网、社交媒体和智能手机的比例与其他种族/族裔群体相同或更高，这代表着一个错失的机会。在过去的 5 年里，这项拟议工作的申请人一直致力于通过开发和评估基于技术的方法来填补已发表研究中的这一空白，以提高 AA 女性的 PA 水平。作为一名行为科学家，他的研究生和博士后培训重点关注社会和心理科学，特别强调针对 AA 女性的理论驱动、文化相关、基于技术的 PA 干预措施的开发和评估。当前申请中提出的研究和培训将通过以下方式扩展和完善候选人的 PA 和健康差异研究轨迹：1）重点培训支持心脏代谢疾病危险因素对 PA 干预的生理和生化机制，2）评估文化相关的智能手机提供的 PA 计划（Smart Walk）的效果，以改善（基线至 6 个月）并维持（7 个月至 12 个月）较高的 PA 水平 AA女性可改善心脏代谢疾病的危险因素。候选人已在亚利桑那州立大学确定了一个支持性和刺激性的研究环境来开展拟议的研究。在导师和博士的指导下。芭芭拉·安斯沃思、科琳·凯勒、格伦·盖瑟和索尼娅·维加-洛佩兹，他将获得必要的技能，使自己成为一名独立的行为和健康差异研究科学家。在拨款的 K99 部分中，申请人将通过教学课程和临床实验室实践经验，对支持 PA 干预的心脏代谢疾病危险因素的生理和生化机制进行明确的培训。该研究领域的培训将补充他已有的强大社会科学背景，使他能够更深入地了解与 PA 增强健康益处相关的生理机制。在拨款的 R00 阶段，申请人将部署在 K99 阶段获得的培训，并通过实施为期 12 个月的基于技术的 PA 随机对照试验，以评估文化相关的智能手机提供的 PA 干预对改善（基线至 6 个月）和维持（7 个月至 12 个月）高 PA 水平并降低肥胖 AA 女性心脏代谢疾病风险的效果，逻辑地建立在其之前的健康差异研究轨迹的基础上。 76 名肥胖 AA 女性将接受使用智能手机应用程序提供的文化相关、基于社会认知理论的 PA 促进计划或健康接触控制条件。将评估 PA、健康和心脏代谢疾病的危险因素。还将探讨 PA 影响心脏代谢疾病危险因素的潜在生理机制。拟议的研究和培训活动支持申请人的近期和长期职业目标。申请人的近期职业目标是加强其基于理论的 PA 研究，包括支持 PA 对健康（即炎症）影响的显着机制，以预防和治疗 AA 女性的心脏代谢疾病危险因素。他的长期职业目标是：a) 建立一个独立的、外部资助的研究计划，重点是确定有效的策略，以促进少数族裔/族裔中持续的 PA，以及 2) 减少高危少数群体中心脏代谢疾病的不成比例的负担。当前 K99/R00 申请中提出的培训和研究活动将帮助候选人实现这些职业目标，并推进 PA 和健康差异科学。
