Predicting PA Adoption among Minority Women Using SEM and Participatory Research

描述(申请人提供)：经常进行体力活动与许多健康结果相关，然而大多数美国成年人仍然难以达到最低体力活动指南，这使得缺乏体力活动成为一个持续的、重大的健康挑战，尤其是在女性和少数族裔中。尽管存在许多经过检验的策略，但几乎没有有效的方法来增加对体育活动的采用，这一领域需要创新。身体活动的生态模型考虑了个人内部因素、人际关系、身体环境和政策，这些因素在采用身体活动时是至关重要的。女性有独特的需求，对健康促进材料和方案的反应可能与男性不同，而且可能对环境条件特别敏感。基于社区的参与性研究战略有望提高体力活动干预措施的相关性和可持续性，并使研究人员能够从社区的角度看待健康问题，而仅有理论家和研究人员可能会忽视这一点。本研究旨在使用混合方法，结合现有的量化数据、深度访谈和分类数据，探索非裔美国人和西班牙裔或拉丁裔女性采用体力活动与个人、社会和环境的相关性，以确定与体力活动采用相关的新因素。我们建议开发两个体力活动采用的概念模型。通过对现有科学文献和理论确定的体力活动的相关性进行广泛的审查，将开发一个基于研究的模型(RBM)。将利用社区成员的看法和来自深入访谈和堆放分类活动的投入，开发一个基于社区的模式(CBM)。由文献和社区成员确定的关联者将通知要包括在模型中的潜在结构的发展。模型将使用现有的问卷和来自Health is Power项目(PI：Lee，1R01CA109403)的客观评估数据进行分析。模型匹配指数将首先被用来定义最适合的RBM和CBM，然后将在模型之间进行比较，以确定哪种模型更好地预测非裔美国人、西班牙裔或拉丁裔女性采用体力活动。这一奖学金是完善申请者技能和加强培训活动的独特机会。研究结果将为申请者的论文和博士课程以及公共卫生的科学和实践贡献有关少数民族妇女采用体力活动的生态、多层次机制的知识。由此产生的预测非洲裔美国人和西班牙裔或拉丁裔女性采用体育活动的模型可能被用于指导未来的干预发展和体育活动研究。

DESCRIPTION (provided by applicant): Regularly done physical activity has been associated with numerous health outcomes, yet the majority of U.S. adults still struggle to meet minimum physical activity guidelines, making physical inactivity an ongoing, significant health challenge particularly among women and minorities. Although numerous tested strategies exist, there are few effective methods to increase adoption of physical activity and innovation in this arena is needed. The Ecologic Model of Physical Activity takes into account intrapersonal factors, interpersonal relationships, the physical environment and policies that are critical in the adoptio of physical activity. Women have unique needs, and may respond differently from men to health promotion materials and protocols, and may be especially sensitive to environmental conditions. Community based participatory research strategies hold promise for enhancing relevance and sustainability of physical activity interventions and allow researchers to gain a community perspective of health problems that theorists and researchers alone may miss. This study aims to explore individual, social and environmental correlates of physical activity adoption among African American and Hispanic or Latina women using a mixed-method approach, combining existing quantitative data with in-depth interviews and pile-sort data to identify novel factors associated with for physical activity adoption. We propose to develop two conceptual models of physical activity adoption. A research-based model (RBM) will be developed by conducting an extensive review of correlates of physical activity indentified by the existing scientific literatue and theories. A community-based model (CBM) will be developed using community members' perceptions and input from in-depth interviews and pile-sort activities. Correlates identified by the literature and community members will inform the development of latent constructs to be included in the models. Models will be analyzed using existing questionnaire and objective assessment data from the Health Is Power project (PI: Lee, 1R01CA109403). Model fit indices will be used to first define the best fitting RBM and CBM, and will then be compared between models to determine which model is a better predictor of physical activity adoption among African American and Hispanic or Latina women. This fellowship is a unique opportunity to refine the applicant's skills and reinforce training activities. Results will contribute knowledge about ecologic, multilevel mechanisms underlying adoption of physical activity among minority women to the applicant's dissertation and doctoral program and to science and practice of public health. The resulting model to predict physical activity adoption among African American and Hispanic or Latina women may be used to guide future intervention development and physical activity research.
