项目摘要

Abstract In the U.S., Latina women report higher rates of inactivity than their non-Hispanic White and male counterparts, and are disproportionately affected by related health conditions (e.g., cancer, hypertension, heart disease, stroke, diabetes). To address this public health crisis, evidence-based interventions that utilize state-of-the-art technology, theory and methods are needed to increase physical activity (PA) among this high-risk population. Recently, our team conducted a randomized controlled trial (N=205) to test the efficacy of a 6-month culturally adapted, individually tailored, Spanish-language Internet-based PA intervention among Latinas (Pasos Hacia La Salud, R01CA159954) vs. a Wellness Contact Control Internet Group. Increases in minutes/week of moderate-to-vigorous physical activity (MVPA) were significantly greater in the Intervention Group compared to the Control Group at 6 and 12 months (p < .01) but still did not reach levels recommended in the national physical activity guidelines. As improvements in PA in the Intervention Group were significantly associated with website use and increases in self-efficacy, enjoyment, and social support in the parent study, we used these data to inform technology and theory-supported enhancements to the intervention (i.e., text messaging and adaptive goal setting to increase website use and further targeting of the previously mentioned key psychosocial constructs) to achieve even greater increases in PA, and maintain these gains over the long term (24 months) in the renewal of R01CA159954. For the proposed study, 300 Latina women will be randomized to either 1) the original Pasos Hacia La Salud tailored Internet-based PA intervention (Original Intervention) or 2) the data driven, enhanced version of the Pasos Hacia La Salud PA intervention (Enhanced Intervention). We hypothesize that participants in the Enhanced Intervention arm will report significantly more minutes/week of MVPA than participants in the Original Intervention arm at 6 months. We will also examine the maintenance of treatment effects at 12, 18, and 24 months, as well as the costs of delivering the Enhanced vs. Original Intervention programs, and the potential mediators of the intervention-PA relationship. The proposed high- reach, low-cost intervention holds great promise in promoting and maintaining the positive health benefits of PA in the lives of Latina women in the United States.

抽象的在美国，拉丁裔妇女报告的无活动率高于其非西班牙裔白人和男性的妇女，并受到相关健康状况（例如癌症，高血压，心脏病，中风，糖尿病）。为了解决这一公共卫生危机，利用最先进的基于证据的干预措施需要技术，理论和方法来增加这种高风险人群中的体育活动（PA）。最近，我们的团队进行了一项随机对照试验（n = 205），以测试6个月在文化上的疗效在拉丁裔中改编，量身定制的西班牙语基于互联网的PA干预（Pasos Hacia La Salud，R01CA159954）与健康联系控制互联网组。数分钟/周的增加与对照组在6和12个月（p <.01），但仍未达到国家建议的水平体育活动指南。由于干预组的PA的改进与网站在父母研究中使用并提高自我效能感，享受和社会支持，我们使用了这些为技术和理论支持的数据提供了对干预措施的增强（即文本消息传递和自适应目标设定以增加网站使用并进一步定位上述密钥心理社会的构造）以实现PA的更大增加，并长期保持这些收益（24个月）在R01CA159954的续签中。在拟议的研究中，将有300名拉丁裔妇女随机分配给 1）原始的pasos hacia la salud量身定制的基于互联网的PA干预（原始干预）或2）数据驱动的，增强的版本的Pasos Hacia la Salud PA干预（增强的干预措施）。我们假设加强干预组的参与者将报告更多的时间/周 MVPA比原始干预部门的参与者在6个月时。我们还将检查 12、18和24个月的治疗效果以及提供增强与原始的成本干预计划，以及干预PA关系的潜在调解人。提议的高级覆盖范围，低成本干预在促进和维持积极的健康益处方面有很大的希望 PA在美国的拉丁裔妇女的生活中。
