Mujeres en Accion: Walking in Hispanic Women

描述（由申请人提供）：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。少数旨在促进西班牙裔妇女体育活动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，以开发和评估的有效性，以理论为基础的社会支持干预计划，“妇女在行动：走在西班牙裔妇女，”接地在以前的研究与种族多样化的妇女，以促进启动和维护定期体育活动的西班牙裔妇女。具体目标是：1.通过参加者流失、可接受性和妇女行动会议的出席情况，审查妇女行动的可行性; 2.探讨妇女行动对社会支持知觉的理论中介变量的影响。确定妇女行动参与者在6个月和12个月时PA、BMI、身体成分和体脂分布的行为结果变化的效应量。干预方案是基于文献和先前的研究。“妇女参与行动”干预措施的主要组成部分包括：（a）社会网络支持，包括由受过培训的Promotoras领导的以社区为基础的团体干预形式;（B）情感支持;（c）工具支持;（d）信息支持;（e）评估支持。将从USPHS社区卫生中心招募88名西班牙裔妇女，并将其随机分配到治疗组（步行干预）或对照组。参与者将被评估社会支持和邻里资源，身体脂肪和脂肪分布的心血管结果。 导致西班牙裔女性冠心病高发的因素包括超重和肥胖以及缺乏体力活动。我们提出了一个试点项目，以评估理论驱动的社会支持干预计划的有效性和可行性，“Mujeres en Accion：在西班牙裔妇女中行走”，以先前对不同种族妇女的研究为基础，以促进定期PA的启动和维持，并降低西班牙裔妇女的心血管风险。

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
