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 美国大多数成年人没有达到国家体力活动(PA)的推荐标准，少数族裔较少 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 美国社会环境中可预防的发病率和死亡率被广泛认识到 对PA的重要影响，但干预研究中对社会背景的研究仍然不足。的目标是 建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 在不活跃的主要是拉丁裔和非裔美国人的妇女中，PA的积极和持续的变化 德克萨斯州休斯顿二元体将首先被随机分配给二元体干预或个体条件。 在个人情况下，每个二人组中的一名妇女随后将被随机分配到个人 并对另一名女性进行健康教育对照。二元性和个体性干预将 包括基于电话的健康指导、Fitbit和健康教育时事通讯，以增强动力 以及提高PA的行为技巧。二元干预的健康指导还侧重于 通过培训双方积极的沟通策略，培养参与者成为支持性伙伴的能力 并以不带偏见和同理心的方式提供支持。健康教育控制将包括一个 Fitbit和健康教育通讯。研究参与者将包括500人，主要是拉丁裔和非洲人 美国不活跃的妇女被招募和登记为二人组(例如，家人或朋友；n=250个二元组)。这个 干预扩展到由调查团队进行的试点随机试验，该试验显示 提供了支持的证据，并确定了需要改进的领域。参与者将在基线上进行评估，6 在基线后12个月，以评估中期和长期效果。初级阶段 结果是中等强度PA的每周分钟数发生了变化。下半身力量，人体测量 测量指标(即BMI、腰围)、久坐行为、平均每日步数和血压是 次要结果。自主动机、社会支持、自主支持、自我效能感与结果 期望值将被视为PA变化的潜在中介因素。建议的研究具有创新性。 它将二元干预与个人干预进行了比较，并强调了二元社会 除了标准的行为改变策略之外的流程。这项干预明确针对现有的社会 网络，以培育支持健康行为改变的社会环境，这些改变将持续到 干预期。这项研究有望获得关于是否以及如何具有特征的批判性见解 社会背景可以被修改以支持健康的生活方式的改变，以此作为解决 主要是拉美裔和非洲裔美国女性的癌症和慢性病风险。
