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，拉丁裔女性的不活动率高于非西班牙裔白人和男性同行，并且受到相关健康状况（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，需要利用最先进的循证干预措施需要技术、理论和方法来增加这一高危人群的体力活动（PA）。最近，我们的团队进行了一项随机对照试验（N=205）来测试为期 6 个月的文化培养效果针对拉丁裔人群进行适应性调整、个性化定制、基于西班牙语的基于互联网的 PA 干预措施 (Pasos Hacia La Salud，R01CA159954）与健康接触控制互联网组织。每周增加分钟数与干预组相比，干预组的中度至剧烈体力活动 (MVPA) 明显更高对照组在 6 个月和 12 个月时达到了这一水平 (p < .01)，但仍未达到国家建议的水平身体活动指南。由于干预组 PA 的改善与在家长研究中，我们使用了网站的使用以及自我效能、享受和社会支持的增加数据为干预措施提供技术和理论支持的增强信息（即短信和自适应目标设置，以增加网站使用并进一步针对前面提到的关键心理社会结构）以实现 PA 的更大增加，并长期保持这些收益（24个月）在R01CA159954的更新中。在拟议的研究中，300 名拉丁裔女性将被随机分配到 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) Pasos Hacia La Salud PA 干预（增强干预）的数据驱动增强版。我们假设强化干预组的参与者每周报告的分钟数显着增加 MVPA 比原始干预组的参与者晚 6 个月。我们还将检查维护 12、18 和 24 个月的治疗效果，以及提供增强型与原始型的成本干预计划，以及干预与 PA 关系的潜在中介。拟议的高低成本的干预措施在促进和维持积极的健康益处方面具有巨大的希望 PA 在美国拉丁裔女性的生活中。
