Black women are disproportionately affected by both physical inactivity and asthma. Lifestyle physical activity (PA) interventions targeted for Black women with asthma are lacking.
To assess the feasibility and acceptability as well as preliminary effects of a lifestyle PA intervention culturally tailored for Black women with asthma.
Black women (age 18-70 years) with uncontrolled asthma (Asthma Control Test <20) were recruited. Outcome assessments at baseline and 24 weeks included measures of: feasibility and acceptability, asthma control, quality of life, health care use, and PA levels. Participants were randomized to the intervention (asthma education, Fitbit, monthly group sessions, text messages, individual step goals, and study manual) or enhanced usual care (EUC) (asthma education plus Fitbit) group.
Of the 53 women randomized (EUC = 28; intervention = 25), 92% remained in the intervention (23 of 25) and 76% completing the 24-week outcome assessment. Overall intervention satisfaction (mean score, 6.88 of 7) and individual components were high at 24 weeks. Mean change in asthma control questionnaire between groups was not significant at 24 weeks (intervention = -0.41 vs EUC = 0.03 [P = .08]; effect size = -0.38) but approached clinical significance (0.5). At 24 weeks, more women receiving the intervention had controlled asthma compared with EUC (36.84% vs 9.52%; P = .04). Clinically significant improvements (0.5) in quality of life were found in the intervention group (mean change: intervention = 0.58 vs EUC = 0.10; P = .10) at 24 weeks.
A culturally tailored lifestyle PA intervention is feasible and demonstrates improvements in asthma control and quality of life among Black women with asthma. These preliminary findings support the need for PA lifestyle interventions in urban Black women with asthma.
身体活动不足和哮喘在黑人群体中发病率过高。针对哮喘黑人女性的生活方式体力活动（PA）干预措施相对较少。
评估为哮喘黑人女性量身定制的生活方式 PA 干预措施的可行性、可接受性以及初步效果。
招募年龄在 18-70 岁之间、哮喘控制不佳（哮喘控制测试<20）的黑人女性。基线和 24 周的评估结果包括：可行性和可接受性、哮喘控制、生活质量、医疗保健使用和 PA 水平。参与者被随机分配到干预组（哮喘教育、Fitbit、每月小组会议、短信、个人目标步数和研究手册）或增强常规护理组（EUC）（哮喘教育加 Fitbit）。
在 53 名随机分组的女性中（EUC=28；干预组=25），92%的人留在干预组（25 人中有 23 人），76%的人完成了 24 周的结局评估。在 24 周时，整体干预满意度（平均评分 7 分中的 6.88 分）和个别组成部分都很高。24 周时，两组间哮喘控制问卷的平均变化不显著（干预组=-0.41，EUC=0.03[P=0.08]；效应量=-0.38），但接近临床意义（0.5）。在 24 周时，接受干预的女性中哮喘控制率高于 EUC（36.84%比 9.52%；P=0.04）。在 24 周时，干预组的生活质量有显著改善（0.5）（平均变化：干预组=0.58，EUC=0.10；P=0.10）。
一项文化上量身定制的生活方式 PA 干预措施是可行的，可改善哮喘黑人女性的哮喘控制和生活质量。这些初步发现支持在有哮喘的城市黑人女性中开展 PA 生活方式干预措施的必要性。
