Developing a Text Message Enhanced Physical Activity Intervention for Latino Men

描述（由申请人提供）：墨西哥裔美国人（MA）男性报告的身体活动率（PA）特别低，并且不成比例地受到与久坐生活方式相关的疾病（例如，糖尿病，肥胖）的负担。由于文化、社会经济地位、教育和语言的差异，MA男性获得促进PA的公共卫生干预措施的机会可能有限。为了解决这些日益扩大的健康差距，需要对男性采取利用最先进技术、理论和方法的有效干预措施。我们的研究团队有25年的经验，开发和实施个性化的PA干预措施。我们在文化和语言上为拉丁裔妇女量身定制了印刷干预措施，然后在两项随机对照试验中证明了其有效性。这一研究经验使我们能够很好地解决男性男性中与pa相关的健康差异。由于这方面的研究缺乏，我们对讲西班牙语的男性进行了定性访谈（N=10）。他们的反馈通知了我们对PA干预的修改以及新材料的创建，然后在MA男性（N=10）的示范试验中进行了测试。12周后，参与者报告每周PA显著增加（平均增加124分钟，sd=154.86, p =.03），保留率为100%。然而，只有40%的人达到了每周150分钟的PA指南，30%的人没有采取任何活动，这表明可能需要更强化的干预。后续采访显示，这些男性喜欢印刷材料，但也想要更大的责任感，更多地与员工和彼此接触，更短更频繁的提示，以及更多的活动机会更新。他们建议增加短信功能来解决这些问题。因此，本研究的目的是通过开发新的文本传递干预材料来补充我们基于印刷的干预措施，以建立我们定制的印刷干预措施，现在将包括印刷的定制环境报告。在第一阶段，我们将与MA男性进行6个焦点小组，以确定所需的文本信息的内容、频率和类型，并确定要纳入现有和新材料的文化主题。焦点小组的主题和文本信息样本将提交给确认小组。第二阶段将是一项为期6个月的试验性随机对照试验，涉及MA男性（N=60），以测试文本增强的、西班牙语的、量身定制的PA干预措施与公开提供的西班牙语健康教育材料，包括PA、饮食和压力管理信息。随后将进行干预后的定性访谈，以征求改进建议，以帮助进一步完善该计划。建议的试验将支持未来的R01，以确定这种多媒体，多层次的PA干预对MA男性的有效性。

DESCRIPTION (provided by applicant): Mexican American (MA) men report particularly low rates of physical activity (PA) and are disproportionately burdened by conditions related to sedentary lifestyle (e.g., diabetes, obesity). Due to cultural, SES, educational, and language differences, MA men may have limited access to public health interventions promoting PA. To address these rising health disparities, effective interventions that leverage state-of-the-art technology, theory, and methods are needed for MA men. Our research team has 25 years of experience developing and implementing individually tailored PA interventions. We culturally and linguistically tailored our print intervention for Latina women and then demonstrated its efficacy in two RCTs. This research experience leaves us well poised to address the PA-related health disparities in MA men. Due to the dearth of studies in this area, we conducted qualitative interviews with Spanish speaking MA men (N=10). Their feedback informed the modifications of our PA intervention as well as the creation of new materials, which were then tested in a demonstration trial with MA men (N=10). After 12 weeks, participants reported significant increases in weekly PA (Mean increase=124 minutes, sd=154.86, p =.03) with 100% retention. However, only 40% met the PA guidelines of 150 minutes/week and 30% did not adopt any activity, suggesting a more intensive intervention may be necessary. Follow-up interviews revealed that the men liked the print materials but also wanted greater accountability, more contact with staff and each other, shorter and more frequent tips, and more updates on activity opportunities. The men recommended adding a text message component to address these issues. Thus, the aim of this study is to build upon our tailored print intervention by developing new text-delivered intervention materials to complement our print-based intervention, which will now include printed tailored environmental reports. In Phase 1 we will conduct 6 focus groups with MA men to determine content, frequency, and types of text messages desired, and to identify cultural themes to incorporate into existing and new materials. Themes from the focus groups and sample text messages will be presented to a confirmatory panel. Phase 2 will be a 6-month pilot RCT with MA men (N=60) to test the text- enhanced, Spanish language, individually tailored PA intervention vs. publicly available, Spanish language health education materials, including information on PA, diet, and stress management. This will be followed by post-intervention qualitative interviews to solicit suggestions for improvements to help further refine the program. The proposed pilot will support a future R01 to establish the efficacy of this multi-media, multi-level PA intervention for MA men.
