项目摘要

ABSTRACT Cancer is the leading cause of death among Latinos in the U.S. While engaging in a physically active lifestyle is one of the most important modifiable behaviors for reducing cancer risk; few Latinas achieve health- enhancing levels of physical activity (PA) recommended by the National PA Guidelines, particularly for muscle- strengthening activities (MSA). For instance, 44% of Latinas meet the national guidelines for aerobic PA but only 17% meet the full guidelines for both aerobic and MSA. While the benefits of aerobic MVPA are well established for cancer and chronic disease prevention, participating in regular MSA may be key to further reducing cancer risk, as adherence to MSA guidelines has been associated with a 19% to 31% lower cancer mortality risk, independent of aerobic PA. There is a need for interventions promoting MSA in Latinas. However, only a select few MSA interventions have included Latinas in their sample, and none to our knowledge, were designed exclusively for this group or addressed socio-cultural factors influencing Latinas' muscle-strengthening behaviors (e.g., perception that MSA is for men; MSA is an avoided topic in their culture and social circles; belief that women should only do certain types of MSA). Moreover, existing interventions often involved in-person exercise programs, which can be inaccessible to many Latinas due to barriers such as lack of transportation or fear of immigration enforcement. Our research team has previously developed and tested aerobic moderate-to-vigorous PA (MVPA) interventions for Latinas that overcome barriers to in-person programs and address PA-related socio-cultural factors. These theory-driven, individually tailored interventions have shown success at increasing aerobic MVPA among Latina women in both print and Internet-based randomized controlled trials. Thus, our web-based intervention (Pasos Hacia la Salud), in particular, provides an ideal platform for promoting muscle-strengthening PA in this at-risk population. To address the gap in literature on muscle-strengthening PA, we recently conducted qualitative interviews with 19 Latinas to identify theory-based barriers and facilitators of muscle-strengthening PA, then developed MSA intervention materials and are further refining for cultural appropriateness, relevance, and appeal in Latinas. In the proposed research, we will incorporate the newly developed MSA promotion materials into our existing Pasos Hacia la Salud (Pasos) web-based aerobic MVPA intervention and conduct a 12-week fully online randomized pilot trial testing the preliminary efficacy of the newly adapted web-based aerobic plus MSA intervention for Latinas. Fifty Latina adults (i.e., aged 18-65 years) will be randomized to either the: 1) original Pasos aerobic MVPA intervention arm, or 2) a Pasos aerobic MVPA plus MSA intervention arm. Our study aims to 1) Assess the preliminary efficacy of the aerobic and muscle-strengthening intervention for increasing MSA, and 2) Explore potential mediators and moderators of MSA. This interactive and highly disseminable approach can achieve significant health improvements in an at-risk population.

抽象的癌症是美国拉丁美洲人在从事身体活跃生活方式的同时死亡的主要原因是降低癌症风险的最重要的修改行为之一；很少有拉丁裔实现健康 - 提高国家PA指南建议的体育锻炼水平（PA），特别是对于肌肉加强活动（MSA）。例如，有44％的拉丁裔符合国家有氧PA的指南，但只有17％符合有氧和MSA的完整指南。有氧MVPA的好处很好参与常规MSA的癌症和慢性疾病预防成立可能是进一步的关键降低癌症风险，因为遵守MSA指南与癌症降低19％至31％有关死亡风险，独立于有氧PA。需要在拉丁裔中促进MSA的干预措施。但是，只有很少的MSA干预措施在其样本中包含了拉丁裔，而我们知识是专门为该群体设计的，或针对影响拉丁裔的社会文化因素的设计加强肌肉加强行为（例如，MSA是男性的； MSA是其文化中避免的话题和社交界；相信妇女只能做某些类型的MSA）。此外，现有干预措施通常涉及面对面的锻炼计划，由于诸如等障碍，许多拉丁裔都无法访问缺乏运输或对移民执法的恐惧。我们的研究团队以前已经开发了对拉丁裔的有氧运动中度到刺激的PA（MVPA）干预措施克服了面对面的障碍计划并解决与PA相关的社会文化因素。这些理论驱动的，单独定制的干预措施在基于印刷和互联网的拉丁裔女性中，在拉丁裔女性中表现出了成功的成功MVPA 随机对照试验。因此，特别是我们基于网络的干预措施（Pasos hacia la Salud）提供了在这种高危人群中促进肌肉强化PA的理想平台。解决差距有关肌肉强度加强PA的文献，我们最近与19个拉丁裔进行了定性访谈，以识别然后，基于理论的肌肉加强PA的障碍和促进因子，然后开发了MSA干预材料并进一步完善了拉丁裔文化适当性，相关性和吸引力。在提议中研究，我们将将新开发的MSA促销材料纳入现有的Pasos Hacia la Salud（PASO）基于Web的有氧MVPA干预并进行为期12周的全线随机试验试验测试新型基于Web的有氧运动和拉丁裔MSA干预的初步疗效。五十拉丁裔成年人（即18-65岁）将随机分为：1）原始PASOS有氧MVPA 干预组，或2）PASOS有氧MVPA加MSA干预组。我们的研究旨在1）评估有氧和肌肉加强干预措施的初步疗效以增加MSA，并探索2） MSA的潜在介体和主持人。这种交互式且高度可观的方法可以实现高危人口的健康改善。
