DESCRIPTION (provided by applicant): Latinos are the fastest growing ethnic group in the US and are disproportionately impacted by chronic conditions (e.g., overweight/obesity, diabetes) that can be mitigated by physical activity. While evidence-based programs are available to improve physical activity, dissemination is constrained by reliance on costly, limited resources. Short message service (SMS or text messaging) has strong potential as an intervention medium for Latinos, as they are dominant users of mobile phones and text messaging, including those with limited literacy and computer skills. We propose to develop a personalized, culturally-congruent and interactive SMS program to promote the adoption and maintenance of physical activity for overweight, underactive Latino adults and test it for comparable efficacy to an evidence-based telephone-based advising program that has been used successfully with Latinos. Grounded in Social Cognitive and Self-Determination Theories, both programs will include a core set of self-regulatory skill building, social support, and autonomous motivation enhancement, and will be tailored for cultural, linguistic and literacy appropriateness. Randomized at the individual level, 376 sedentary, overweight Latinos ages 45 years and older will be assigned to one of three arms: the SMS- delivered physical activity program, the Human-delivered physical activity program, or an attention-control arm of SMS-delivered basic healthful nutrition advice. They will receive their assigned program for 12 months, and then will be followed for a 6-month maintenance phase, with a final assessment at 18 months. Analyses will determine if the two physical activity programs result in equivalent efficacy in adoption and maintenance of clinically meaningful physical activity increases, and superiority over the attention-control arm at 12 and 18 months. The two physical activity interventions will also be compared for equivalency in prevention of weight gain and reduction in abdominal adiposity. We will explore the relative costs of the programs to determine which program increases physical activity for a lower cost. While health promotion programs delivered by professional staff may be more expensive than those delivered electronically, it is unclear if the automated version can produce more cost-efficient outcomes (i.e., comparable improvements in outcomes for significantly reduced cost). This study will determine if SMS is equivalent in efficacy to the traditional human-delivery channel in increasing physical activity and preventing weight gain, and if it results in a more cost-efficient program. If achieved, this research can significantly reduce health disparities associated with physical activity for Latinos by providing an efficacious tailored and culturally appropriate program poised for widespread dissemination and rapid uptake.

描述（由申请人提供）：拉丁裔是美国增长最快的族裔，受到慢性病（例如超重/肥胖症，糖尿病）的影响，可以通过体育活动来减轻。尽管有证据的计划可用于改善体育活动，但传播受到依赖昂贵，有限的资源的限制。简短的消息服务（SMS或文本消息传递）作为拉丁美洲人的干预媒介具有强大的潜力，因为它们是手机和文本消息传递的主要用户，包括那些识字和计算机技能有限的用户。我们建议开发一个个性化的，具有文化的和互动的SMS计划，以促进对体育活动的采用和维护，以实施超重，不足的拉丁裔成年人，并将其与基于循证电话的基于循证的咨询计划进行可比的功效，该计划已成功用于拉丁裔。以社会认知和自决理论为基础，这两个程序都将包括一组自我调节技巧，社会支持和自主动机增强的核心，并将针对文化，语言和识字适当性量身定制。在单个层面上随机分配376个久坐的，超重的拉丁美洲人45岁及45岁以上的拉丁美洲人将被分配给三个臂之一：SMS提供的体育锻炼计划，人提供的体育锻炼计划或SMS提供的基本健康营养建议的注意力控制。他们将收到分配的计划12个月，然后将进行6个月的维护阶段，并在18个月时进行最终评估。分析将确定两个体育活动计划是否在临床上有意义的体育活动增加和维持临床意义上的增长方面是否会产生同等的功效，并且在12个月和18个月时注意力控制方面的优越性比对照组的优势。还将比较两种体育活动干预措施，以预防体重增加和腹部肥胖的减少。我们将探讨该计划的相对成本，以确定哪个程序以较低的成本增加了体育活动。尽管专业员工提供的健康促进计划可能比以电子方式交付的计划更昂贵，但尚不清楚自动化版本是否可以产生更具成本效益的结果（即，成本可显着降低的成本的可比性改善）。这项研究将确定SMS是否在增加体育锻炼和防止体重增加以及导致更具成本效益的计划方面与传统的人交付通道的疗效等效。如果实现的话，这项研究可以通过提供有效的量身定制且具有文化适当的计划，可以大大降低与拉丁美洲人体育锻炼相关的健康差异，该计划有助于广泛传播和快速吸收。
