DESCRIPTION (provided by applicant): In the U.S., Latino women (Latinas) report higher rates of inactivity than their non-Hispanic White and male counterparts and thus are disproportionately burdened by related health conditions (e.g., cancer, hypertension, heart disease, stroke, diabetes). Cultural factors, socioeconomic circumstances, language and educational barriers limit Latinas access to public health interventions that promote physically active lifestyles. To address this public health crisis, effective interventions that leverage state-of-the-art theory and methods are needed to reach this at-risk population. Our research group has over 20 years experience developing and evaluating individually-tailored, computer expert system-driven, physical activity interventions (based on Social Cognitive Theory and the Transtheoretical Model) through various channels and settings. In our recent pilot (R21NR009864), we culturally and linguistically adapted our tailored intervention for sedentary Latinas and conducted a small randomized trial of the modified program (N=93). A total of 81 participants completed the 6- month study (87 percent retention) and increased their physical activity from a mean of 17 minutes per week (SD=25.76) at baseline to 147 minutes (SD=241.55) at six months whereas contact control participants increased their physical activity from 12 minutes per week (SD=21.99) at baseline to 97 minutes (SD=118.49) at six months. These observed improvements in physical activity in our intervention group, along with high retention rates, participant-reported desire for an Internet-delivered program, and formative work developing our program in an Internet format lend support for testing an Internet intervention tailored to the needs of Latinas. Therefore, for the current application, we will build on our previous work by conducting an adequately powered (N=200) randomized controlled trial to test the efficacy of our culturally and linguistically modified, individually tailored physical activity intervention delivered via the Internet relative to an Internet wellness contact control condition (including cardiovascular health information developed for Latinos by the NHLBI). Data will be collected at baseline, 6 months (post-treatment), and 12 months (maintenance) using well- established physical activity measures (7-Day PAR, Actigraphs), as well as a comprehensive set of psychosocial questionnaires. We hypothesize that at end of treatment (month six) intervention participants will report significantly more minutes of moderate intensity physical activity per week than the wellness contact control participants. We will also examine the maintenance of treatment effects at 12 months, potential mediators and moderators of the intervention-physical activity relationship, and the costs of delivering the tailored Internet program. In the proposed study we seek to promote physical activity among an underserved population using a high-reach, low-cost, technology-based strategy, which has great potential for adoption on a larger scale and thus high potential for reducing health disparities in the U.S.

描述（由申请人提供）：在美国，拉丁裔女性（拉丁裔）的不活动率高于非西班牙裔白人和男性同行，因此相关健康状况（例如癌症、高血压、心脏病、中风）的负担不成比例。 ， 糖尿病）。文化因素、社会经济环境、语言和教育障碍限制了拉丁裔获得促进身体活跃生活方式的公共卫生干预措施。为了解决这一公共卫生危机，需要利用最先进的理论和方法采取有效的干预措施来覆盖这一高危人群。我们的研究小组拥有 20 多年通过各种渠道和环境开发和评估个性化、计算机专家系统驱动的身体活动干预措施（基于社会认知理论和跨理论模型）的经验。在我们最近的试点项目 (R21NR009864) 中，我们从文化和语言角度调整了针对久坐拉丁裔的定制干预措施，并对修改后的计划进行了一项小型随机试验 (N=93)。共有 81 名参与者完成了为期 6 个月的研究（87% 的保留率），并将他们的体力活动从基线时的平均每周 17 分钟 (SD=25.76) 增加到六个月时的 147 分钟 (SD=241.55)，而接触控制参与者的体力活动从基线时每周 12 分钟 (SD=21.99) 增加到六个月时的 97 分钟 (SD=118.49)。在我们的干预组中观察到的身体活动的改善，以及高保留率、参与者报告的对互联网提供的计划的渴望，以及以互联网格式开发我们的计划的形成性工作，为测试适合需要的互联网干预提供了支持。拉丁裔。因此，对于当前的应用，我们将在之前的工作基础上进行一项充分有力的（N = 200）随机对照试验，以测试我们通过互联网提供的经过文化和语言修改、个性化定制的身体活动干预相对于互联网健康接触控制状况（包括 NHLBI 为拉丁裔开发的心血管健康信息）。将使用完善的体力活动测量（7 天 PAR、Actigraphs）以及一套全面的心理社会问卷在基线、6 个月（治疗后）和 12 个月（维持）收集数据。我们假设，在治疗结束时（第六个月），干预参与者报告的每周中等强度身体活动的分钟数将明显多于健康接触对照参与者。我们还将检查 12 个月时治疗效果的维持情况、干预与身体活动关系的潜在中介因素和调节因素，以及提供定制互联网计划的成本。在拟议的研究中，我们寻求利用高覆盖范围、低成本、基于技术的策略来促进服务不足人群的体育活动，该策略具有大规模采用的巨大潜力，因此很有可能减少美国的健康差距。
