项目摘要

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（由适用提供）：项目摘要/摘要国家数据显示，有82％的非裔美国人（AA）妇女超重或肥胖，57％的妇女肥胖。与AA妇女之间的超重和肥胖症患病率有关的健康风险与随后的慢性病有关，包括心血管疾病（CVD）和2型糖尿病（T2D）。体育锻炼（PA）是管理体重和改善众多心脏代谢疾病危险因素的既定机制。但是，这些好处是，只有36％的AA妇女符合国家宾夕法尼亚州的指南。 AA妇女的PA水平较低，加上超重/肥胖症和其他慢性疾病状况的高流行率表明，需要有效的策略来促进这种高风险人群中持续的高PA。基于技术的平台（即智能手机应用程序，互联网，社交媒体）代表了向AA妇女提供PA干预的潜在渠道。但是，很少有研究人员探索了这些平台，以向AA妇女提供与文化相关的PA干预。鉴于与其他种族/族裔群体相比，AA女性使用互联网，社交媒体和智能手机使用互联网，社交媒体和智能手机，这是一个错过的机会，这表明行为变更干预措施和数据表明，AA女性使用互联网，社交媒体和智能手机。在过去的五年中，这项拟议工作的适用集中在通过开发和评估基于技术的方法来增加AA妇女中PA的方法来填补这一空白。作为行为科学家培训，他的毕业生和博士后培训集中在社会和心理科学上，特别着重于对理论驱动的，基于文化相关的基于技术的PA干预的发展和评估。当前应用中提出的研究和培训将扩展和完善候选人的PA和健康差异研究轨迹：1）重点培训在物理和生物化学机制中培训，培训涉及心脏代谢疾病的风险因素响应PA干预的响应于PA的干预，以及2）在较高的智能手机PA的效果（7个月）（智能手机）的效果（7个月）（智能步行）（智能步行）（智能步行）（智能步行）（智能启动）（智能率）（智能率）（智能步行）（智能率）（智能率）（智能）（智能）（智能）（智能）（智能）的较高（7个月）（妇女并改善心脏代谢疾病危险因素。候选人已经确定了亚利桑那州立大学的支持性和刺激性的研究环境，以追求拟议的研究。在心态和博士下。芭芭拉·阿恩斯沃思（Barbara Ainsworth），科琳·凯勒（Colleen Keller），格伦·盖瑟（Glenn Gaesser）和索尼亚·维加·洛佩兹（Sonia Vega-Lopez），他将获得必要的技能，以确立自己为独立的行为和健康差异研究科学家。赠款奖的K99部分，适用的将在体育和生化机制中进行明确培训，该机制是通过教学课程和动手临床实验室经验来响应PA干预的心脏代谢疾病风险因素。该研究领域的培训将使他已经强大的社会科学背景允许他对与PA的健康增强益处相关的物理机制有更深入的了解。在赠款奖的R00阶段，适用的培训将在K99阶段进行的培训，并在其先前的健康分布研究轨迹上进行逻辑上，通过实施一个基于12个月的基于技术的PA随机对照试验，以评估具有文化相关的智能手机剥离PA的效果，以改善（基本到6个月），并在7个月内（7个月）降低妇女的疾病，并减少PA级别的次数，并降低了PA级别的次数。 76个肥胖症AA妇女将获得具有智能手机应用程序或健康联系控制条件的基于文化相关的，基于社会认知理论的PA促销计划。 PA，健身和心脏代谢疾病危险因素将进行评估。 PA可能会影响心脏代谢疾病危险因素的潜在生理机制也将被探索。拟议的研究和培训活动支持申请人的直接和长期职业目标。申请人的直接职业目标是增强其基于理论的PA研究，以包括对健康影响（即炎症）影响的显着机制，以预防和治疗AA妇女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金研究计划，重点是确定有效的策略，以促进种族/族裔少数民族之间的持续PA，2）减少高风险少数群体中心脏代谢性疾病的不成比例的伯恩。当前K99/R00应用程序中提出的培训和研究活动将有助于候选人实现这些职业目标，并促进PA和健康差异科学。
