Mujeres en Accion: Walking in Hispanic Women

描述(申请人提供)：导致西班牙裔女性心血管疾病的两个因素是超重和肥胖的流行以及缺乏体力活动。旨在促进拉美裔妇女身体活动的为数不多的社区干预措施显示出不同的效果。我们提出了一个试点项目，以开发和评估一个基于理论的社会支持干预计划的有效性，该计划名为“MuJeres en Accion：在拉美裔妇女中行走”，该计划基于先前对不同种族妇女的研究，以促进拉美裔妇女开始和保持定期的体育活动。本研究的具体目的是：1.通过参与者的流失率、可接受性和参加MuJeres en Accion会议的人数来检验MuJeres en Accion的可行性；2.探索MuJeres en Accion对领悟社会支持的理论中介变量的影响；3.确定MuJeres en Accion参与者在6个月和12个月时改变对PA的行为结果、BMI、身体成分和体脂分布的影响程度。该干预计划是基于文献和先前的研究。MuJeres en Accion干预的主要组成部分包括：(A)社会网络支持，包括由训练有素的推动者领导的以社区为基础的团体干预形式；(B)情感支持；(C)工具性支持；(D)信息支持；(E)评估支持。88名拉美裔妇女将从USPHS社区卫生中心招募，并被随机分配到治疗组(步行干预)或对照组。参与者将从社会支持和邻里资源、身体脂肪的心血管结果和脂肪分布方面进行评估。 导致西班牙裔女性冠心病发病率高的因素包括超重和肥胖以及缺乏体育活动。我们提出了一个试点项目，以评估一个理论驱动的社会支持干预计划的有效性和可行性，该项目基于对不同种族女性的先前研究，以促进启动和维持常规PA，并降低拉美裔女性的心血管风险

DESCRIPTION (provided by applicant): Two factors that contribute to cardiovascular disease in Hispanic women are the prevalence of overweight and obesity and a lack of physical activity. The few community-based interventions designed to promote physical activity among Hispanic women have shown varying effectiveness. We propose a pilot project to develop and evaluate the efficacy of a theory-based social support intervention program, "Mujeres en Accion: Walking in Hispanic Women," grounded in prior research with ethnically diverse women to promote the initiation and maintenance of regular physical activity among Hispanic women. The specific aims are to: 1. Examine the feasibility of the Mujeres en Accion by participant attrition, acceptability, and attendance at Mujeres en Accion sessions; 2. Explore the impact of the Mujeres en Accion on theoretical mediating variable of perceived social support, and 3. Determine the effect size of changes in Mujeres en Accion participants at 6 and 12 months in behavioral outcomes of PA, and BMI, body composition, and body fat distribution. The intervention program is based on literature and prior research. Key components of the Mujeres en Accion intervention include (a) social network support including a community-based, group intervention format led by trained Promotoras, (b) emotional support, (c) instrumental support, (d) informational support, and (e) appraisal support. Eighty-eight Hispanic women will be recruited from USPHS Community Health Centers, and will be randomly assigned to treatment (walking intervention) or control group. The participants will be evaluated on social support and neighborhood resources, cardiovascular outcomes of body fat and fat distribution. Factors that contribute to high rates CHD in Hispanic women include overweight and obesity and a lack of physical activity. We propose a pilot project to evaluate the efficacy and feasibility of a theory-driven social support intervention program, "Mujeres en Accion: Walking in Hispanic Women," grounded in prior research with ethnically diverse women, to promote the initiation and maintenance of regular PA, and reduce cardiovascular risk among Hispanic women
