African American Women (AAW) are disproportionately impacted by both physical inactivity and asthma. The aims of this study were to: 1) understand barriers to physical activity among AAW with asthma; 2) obtain feedback from AAW on an evidence-based walking intervention; and 3) modify the intervention using input from AAW with asthma.
Focus groups and interviews were conducted with sedentary AAW with uncontrolled asthma to identify barriers to walking. Women also suggestions for tailoring an existing walking intervention. Qualitative data were coded using domains from the Behavior Change Wheel and guided modifications of the existing walking intervention to tailor the content for sedentary AAW with asthma.
Six focus groups (2-4 /group) and five interviews were completed. Women (n=20) represented an obese (37 kg/m ± 11), middle-aged (46 years ± 15) and low-income population. Barriers to physical activity were mapped to 8 theoretical domains: 1) Limited physical capability; 2) Lack of knowledge; 3) Lack of self-monitoring skills; 4) Complex decision making processes; 5) Lack of areas to walk; 6) Lack of social support; 7) Beliefs about consequences; 8) Beliefs about capability. To target these barriers, the existing walking intervention was modified to include an asthma education session, text messages, monthly group meetings, a walking session and informational materials.
AAW with asthma reported unique barriers to engaging in physical activity. An assessment of the feasibility, acceptability and efficacy of a modified intervention that addresses these barriers is warranted to address physical inactivity and poor asthma outcomes among AAW with asthma.
非裔美国女性（AAW）受缺乏身体活动和哮喘的影响尤为严重。本研究的目的是：1）了解患有哮喘的AAW进行身体活动的障碍；2）从患有哮喘的AAW那里获得关于一项循证步行干预措施的反馈；3）根据患有哮喘的AAW的意见修改该干预措施。
对久坐不动且哮喘未得到控制的AAW进行焦点小组讨论和访谈，以确定步行的障碍。这些女性还对调整现有的步行干预措施提出了建议。定性数据使用行为改变轮的领域进行编码，并指导对现有步行干预措施进行修改，以便为久坐不动且患有哮喘的AAW量身定制内容。
完成了6个焦点小组讨论（每组2 - 4人）和5次访谈。20名女性代表了肥胖（体重指数37 kg/m² ± 11）、中年（46岁 ± 15）且低收入的人群。身体活动的障碍被归纳为8个理论领域：1）身体能力有限；2）知识缺乏；3）自我监测技能缺乏；4）决策过程复杂；5）缺乏步行区域；6）缺乏社会支持；7）对后果的信念；8）对能力的信念。为了针对这些障碍，对现有的步行干预措施进行了修改，包括哮喘教育课程、短信、每月小组会议、步行活动和信息材料。
患有哮喘的AAW报告了参与身体活动存在独特障碍。有必要评估一项针对这些障碍的修改后的干预措施的可行性、可接受性和有效性，以解决患有哮喘的AAW身体活动不足和哮喘不良后果的问题。
