Predicting PA Adoption among Minority Women Using SEM and Participatory Research

定期进行身体活动与许多健康结果有关，但大多数美国成年人仍然难以达到最低身体活动指南，使身体活动不足成为持续的重大健康挑战，特别是在妇女和少数民族中。虽然存在许多经过测试的策略，但几乎没有有效的方法来增加身体活动的采用，并且需要在这个竞技场中进行创新。身体活动的心理模型考虑到了对身体活动至关重要的个人因素，人际关系，物理环境和政策。妇女有独特的需要，对促进健康的材料和规程的反应可能与男子不同，而且可能对环境条件特别敏感。基于社区的参与性研究策略有望提高身体活动干预措施的相关性和可持续性，并使研究人员能够获得理论家和研究人员可能会错过的健康问题的社区视角。本研究旨在探索个体，社会和环境的相关性，采用混合方法的非裔美国人和西班牙裔或拉丁裔妇女的体力活动采用，结合现有的定量数据与深入访谈和桩排序数据，以确定新的因素与体力活动采用。我们提出了两个概念模型的身体活动采用。一个基于研究的模型（RBM）将通过对现有科学文献和理论所确定的身体活动的相关性进行广泛的审查来开发。将利用社区成员的看法和从深入访谈和成堆分类活动中获得的投入，制定一个基于社区的模式。由文献和社区成员确定的相关性将为模型中包含的潜在结构的开发提供信息。将使用来自健康就是力量项目（PI：Lee，1R01CA 109403）的现有问卷和客观评估数据分析模型。模型拟合指数将首先用于定义最佳拟合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和西班牙裔或拉丁裔女性的身体活动采用。该奖学金是一个独特的机会，以完善申请人的技能和加强培训活动。结果将有助于了解生态，多层次的机制，通过少数民族妇女的身体活动，申请人的论文和博士课程，科学和公共卫生的实践。由此产生的模型，以预测体力活动采用非洲裔美国人和西班牙裔或拉丁美洲妇女可用于指导未来的干预发展和体力活动的研究。 公共卫生相关性：妇女缺乏身体活动的比例高于男子，尽管少数民族更容易受到相关健康损害状况的影响，但少数民族报告的缺乏身体活动的比例高于白人。虽然存在许多经过测试的策略，但几乎没有有效的方法来增加身体活动的采用，并且需要在这个竞技场中进行创新。结合社区参与式研究和结构方程模型，开发一个模型，可用于解释非裔美国人和西班牙裔或拉丁裔妇女的身体活动采用是高度相关的公共卫生。

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. PUBLIC HEALTH RELEVANCE: Physical inactivity rates are higher among women than men, and despite increased vulnerability to related health compromising conditions, ethnic minorities report higher rates of physical inactivity than whites. Although numerous tested strategies exist, there are few effective methods to increase adoption of physical activity and innovation in this arena is needed. Combining community based participatory research and structural equation modeling to develop a model that can be used to explain physical activity adoption among African American and Hispanic or Latina women is highly relevant to public health.
