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裔在积极锻炼的生活方式中死亡的主要原因是降低癌症风险最重要的可改变行为之一；很少有拉丁裔获得健康—— 提高国家 PA 指南建议的体力活动 (PA) 水平，特别是肌肉活动加强活动（MSA）。例如，44% 的拉丁裔人符合国家有氧运动指导方针，但只有 17% 的人符合有氧运动和 MSA 的完整指南。虽然有氧 MVPA 的好处很好为癌症和慢性病预防而建立，参加定期 MSA 可能是进一步预防癌症和慢性病的关键降低癌症风险，因为遵守 MSA 指南可将癌症风险降低 19% 至 31% 死亡风险，与有氧 PA 无关。需要采取干预措施促进拉丁美洲人的 MSA。然而，只有少数 MSA 干预措施将拉丁裔纳入其样本，而我们的样本中却没有。知识，专为该群体设计或解决影响拉丁裔的社会文化因素肌肉强化行为（例如，认为 MSA 适合男性；MSA 在他们的文化中是一个回避的话题和社交圈子；认为女性应该只进行某些类型的 MSA）。此外，现有的干预措施通常涉及面对面的锻炼计划，但由于以下障碍，许多拉丁裔人士可能无法参加这些计划缺乏交通或担心移民执法。我们的研究团队之前已经开发并测试了针对拉丁裔的有氧中度至剧烈 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、个性化的干预措施在印刷品和互联网上都成功地提高了拉丁裔女性的有氧运动 MVPA 随机对照试验。因此，我们基于网络的干预措施 (Pasos Hacia la Salud) 特别提供是在这一高危人群中促进肌肉强化 PA 的理想平台。为了解决这一差距根据关于肌肉强化 PA 的文献，我们最近对 19 名拉丁裔进行了定性访谈，以确定基于理论的肌肉强化PA的障碍和促进因素，然后开发了MSA干预材料并进一步完善拉丁裔文化的适宜性、相关性和吸引力。在提议的研究后，我们将把新开发的 MSA 宣传材料纳入我们现有的 Pasos Hacia la Salud（Pasos）基于网络的有氧MVPA干预并进行为期12周的完全在线随机试点试验测试新近采用的基于网络的有氧运动加 MSA 干预措施对拉丁裔的初步效果。五十拉丁裔成年人（即 18-65 岁）将被随机分配到：1) 原始 Pasos 有氧 MVPA 干预组，或 2) Pasos 有氧 MVPA 加 MSA 干预组。我们的研究目的是 1) 评估有氧运动和肌肉强化干预对于增加 MSA 的初步效果，以及 2) 探索 MSA 的潜在中介者和调节者。这种互动且高度传播的方法可以实现高危人群的健康状况显着改善。
