ACTION, A lifestyle physiCal acTivity Intervention for MinOrity womeN with asthma: From Efficacy to Implementation

项目总结/摘要 缺乏身体活动与哮喘控制和生活质量差以及更多的医疗保健利用有关。 非裔美国人（AA）妇女的身体活动不足、哮喘和哮喘死亡率较高 比他们的白色同行。我们的形成性工作确定了非洲裔美国人中PA的障碍 女性哮喘患者包括缺乏社会支持，自我效能，不安全的邻居和恐惧相关 有危及生命的哮喘急性发作的经历。鉴于PA的独特障碍和高发病率， 缺乏体力活动与非洲裔美国妇女哮喘预后不良有关， 迫切需要为这一人群优化巴勒斯坦权力机构的干预措施。这项研究使用了我们的理论驱动， 干预（行动：对少数哮喘妇女的生活方式和生理活动干预）， 为患有哮喘的城市AA女性提供为期24周的生活方式体育活动干预。 参与者将通过两个城市医疗保健系统招募，这些系统负责照顾多样化的城市AA 人口患者将被随机分为两组：1）ACTION干预（小组会议， 身体活动自我监测和基于文本的目标设定支持），或2）教育控制（个人 哮喘教育会话和与哮喘教育相关的文本消息）。将跟踪参与者， 干预后额外24周，以评估干预对哮喘的维持效果 健康成果。我们提出了一项疗效研究，重点是哮喘的结果（目的1A/B），探讨 干预的行为机制（目标2），并评估影响其影响范围的因素， 执行潜力（目标3）。这项试验将首次提供生活方式有效性的证据 对患有哮喘的城市AA女性进行身体活动干预，这一人群尚未得到充分研究 受到低PA水平和不良健康结果的困扰。我们的研究具有很大的潜力， 治疗哮喘，并进一步了解少数民族的身体活动干预的机制 生活在低资源城市环境中的人口。

Project Summary/Abstract Physical inactivity is associated with poor asthma control and quality of life, and greater health care utilization. Rates of physical inactivity, asthma, and asthma mortality among African American (AA) women are higher than those of their White counterparts. Our formative work identified barriers to PA among African American women with asthma including a lack of social support, self-efficacy, unsafe neighborhood and fear related to experiences with life-threatening asthma exacerbations. Given the unique barriers to PA and high rates of physical inactivity that are associated with poor asthma outcomes in African American women, there is an urgent need to optimize PA interventions for this population. The proposed study uses our theory-driven intervention (ACTION: A lifestyle physiCal acTivity Intervention for minOrity womeN with asthma) to deliver a 24-week lifestyle physical activity intervention designed for and by urban AA women with asthma. Participants will be recruited through two urban health care systems that care for a diverse urban AA population. Patients will be randomized to one of two groups: 1) ACTION intervention (group sessions, physical activity self-monitoring and text-based support for goal-setting), or 2) education control (an individual asthma education session and text messages related to asthma education). Participants will be followed for an additional 24-weeks after the intervention to assess for the maintenance of intervention effects on asthma health outcomes. We are proposing an efficacy study that focuses on asthma outcomes (Aim 1A/B), explores behavioral mechanisms of the intervention (Aim 2) and assesses factors that influence its reach and implementation potential (Aim 3). This trial will provide the first ever evidence of the efficacy of a lifestyle physical activity intervention among urban AA women with asthma, a population that is understudied yet plagued by low levels of PA and poor health outcomes. Our study has high potential to advance clinical treatment of asthma, and further the mechanistic understanding of physical activity interventions in minority populations living in low-resourced urban environments.
