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)男性报告的体力活动率(PA)特别低，并且不成比例地受到与久坐不动的生活方式(如糖尿病、肥胖症)有关的疾病的负担。由于文化、社会地位、教育和语言的差异，MA男性获得促进PA的公共卫生干预的机会可能有限。为了解决这些日益扩大的健康差距，MA男性需要利用最先进的技术、理论和方法进行有效的干预。我们的研究团队拥有25年的个人定制PA干预开发和实施经验。我们从文化和语言上为拉美裔女性量身定做了我们的印刷干预，然后在两个随机对照试验中展示了它的有效性。这一研究经验使我们能够很好地解决MA男性中与PA相关的健康差距。由于缺乏这方面的研究，我们对讲西班牙语的MA男性(N=10)进行了定性访谈。他们的反馈为我们的PA干预以及新材料的创建提供了修改，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124min，SD=154.86，p=0.03)，保留率为100%。然而，只有40%的人达到了PA每周150分钟的指导方针，30%的人没有采取任何活动，这表明可能有必要进行更密集的干预。后续采访显示，这些人喜欢印刷材料，但也想要更大的责任感，与员工和彼此更多的联系，更短和更频繁的小费，以及更多关于活动机会的更新。这些人建议增加一个短信组件来解决这些问题。因此，这项研究的目的是通过开发新的文本传递的干预材料来补充我们的基于印刷的干预措施，其中现在将包括印刷的定制环境报告，从而在我们的定制印刷干预措施的基础上再接再厉。在第一阶段，我们将与MA Man一起进行6个焦点小组，以确定所需短信的内容、频率和类型，并确定要纳入现有和新材料的文化主题。来自焦点小组的主题和文本信息样本将提交给确认性小组。第二阶段将与MA男性(N=60)进行为期6个月的RCT试点，以测试文本增强的西班牙语个人定制PA干预与公开提供的西班牙语健康教育材料，包括PA、饮食和压力管理方面的信息。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。拟议的试点将支持未来的R01，以确定这种针对MA男性的多媒体、多水平PA干预的有效性。

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.
