ABSTRACT Most adults in the U.S. fail to meet national physical activity (PA) recommendations, and minorities are less likely to meet these recommendations than non-Hispanic Whites. Physical inactivity and obesity are major risk factors for cardiovascular disease, certain cancers, diabetes, and stroke and are important contributors to preventable morbidity and mortality in the U.S. Social environments are widely recognized to have an important impact on PA, yet social contexts remain understudied in intervention research. The goal of the proposed research is to evaluate the effectiveness of a 6-month behavioral dyadic intervention to promote positive and sustained change in PA among inactive predominantly Latina and African American women in Houston, TX. Dyads will first be randomly assigned to the dyadic intervention or to an individual condition. Within the individual condition, one woman from each dyad will subsequently be randomized to the individual intervention and the other woman to a health education control. The dyadic and individual interventions will consist of telephone-based health coaching, a Fitbit, and health education newsletters to enhance motivation and behavioral skills for increasing PA. The health coaching for the dyadic intervention additionally focuses on building participants' capacity to be a supportive partner by training dyads in positive communication strategies and offering support in a non-judgmental and empathetic way. The health education control will consist of a Fitbit and health education newsletters. Study participants will include 500 predominantly Latina and African American inactive women recruited and enrolled as dyads (e.g., family or friends; n=250 dyads). The intervention expands upon a pilot randomized trial conducted by the investigative team that showed preliminary evidence of support and also identified areas for improvement. Participants will be assessed at baseline, 6 months, and 12 months after baseline to evaluate both intermediate and long-term effects. The primary outcome is change in minutes per week of moderate-intensity PA. Lower body strength, anthropometric measures (i.e., BMI, waist circumference), sedentary behavior, mean daily steps, and blood pressure are secondary outcomes. Autonomous motivation, social support, autonomy support, self-efficacy, and outcome expectancies will be examined as potential mediators of changes in PA. The proposed research is innovative in its comparison of a dyadic intervention against an individual intervention and in its emphasis on dyadic social processes in addition to standard behavior change strategies. The intervention explicitly targets existing social networks to foster social environments supportive of healthy behavior change that will persist beyond the intervention period. This research is expected to yield critical insight regarding whether and how features of social contexts can be modified to support healthy lifestyle change as a means of addressing disparities in cancer and chronic disease risk among predominantly Latina and African American women.

摘要 在美国，大多数成年人都没有达到国家体育活动（PA）的建议，少数民族更少。 比非西班牙裔白人更有可能达到这些建议。缺乏运动和肥胖是主要风险 心血管疾病，某些癌症，糖尿病和中风的因素，是重要的贡献者 可预防的发病率和死亡率在美国的社会环境被广泛认为有一个 重要的影响PA，但社会背景仍然在干预研究不足。的目标 拟议的研究是评估为期6个月的行为二元干预的有效性，以促进 在非活跃的主要是拉丁裔和非洲裔美国妇女中， 德克萨斯州休斯顿。二元组将首先被随机分配到二元干预或个体条件。 在个体条件下，随后将每个二分体中的一名女性随机分配至个体 干预组和对照组妇女进行健康教育。二元和个人干预将 包括基于电话的健康指导，Fitbit和健康教育通讯，以提高动力 和行为技能来提高PA。二进干预的健康指导还侧重于 通过对两人进行积极的沟通战略培训，培养参与者成为支持性伙伴的能力 并以一种不带偏见和同情心的方式提供支持。健康教育控制将包括 Fitbit和健康教育通讯。研究参与者将包括500名主要是拉丁裔和非洲裔 美国非活跃妇女招募和登记为二人组（例如，家庭或朋友; n=250对）。的 干预扩大了调查小组进行的一项试点随机试验， 支持的证据，并确定了需要改进的领域。将在基线时对参与者进行评估，6 个月和基线后12个月，以评估中期和长期影响。主 结果是中等强度PA每周分钟数的变化。下体力量，人体测量 措施（即，BMI、腰围）、久坐行为、平均每日步数和血压 次要结果。自主性动机、社会支持、自主性支持、自我效能感和结果 预期将作为PA变化的潜在介质进行检查。该研究具有创新性 在比较二元干预与个体干预以及强调二元社会干预时， 除了标准的行为改变策略外，还需要进行过程。干预措施明确针对现有的社会 网络，以促进社会环境的支持，健康的行为改变，将持续超越 干预期。这项研究预计将产生关键的洞察力，关于是否和如何的特点， 可以修改社会环境以支持健康的生活方式改变，作为解决差异的一种手段 癌症和慢性疾病的风险，主要是拉丁美洲和非洲裔美国妇女。
