在不同种族背景的老年移民妇女中，体力活动（PA）、久坐时间（ST）、虚弱和影响PA行为的因素之间的关联证据有限。这项混合方法研究的目的是：1)检查虚弱状态的PA水平和ST；2)确定民族和宗教群体之间PA/ST的差异；3)定性探讨老年（>= 60岁）流动妇女（n = 60） PA的影响因素。使用加速度计评估PA/ST，使用脆弱表型评估脆弱状态。通过半结构化访谈（n = 36）探讨影响PA的关键因素，并采用主题分析进行分析。无论身体状况如何，参与者都是久坐不动的。中度至剧烈体力活动（MVPA）与虚弱独立相关。参与者醒着的时候有69%的时间处于ST状态，只有15%的时间符合目前每周PA的建议。据报道，健康和社会文化因素是实现PA建议的常见障碍。维持独立性，防止身体衰退和抑郁是促进PA的关键因素。了解这一人群的挑战和需求可以帮助制定促进PA的策略，从而优化身体功能。
There is limited evidence examining the association between physical activity (PA), sedentary time (ST), frailty, and factors influencing PA behaviors in migrant older women from ethnically diverse backgrounds. The aims of this mixed-methods study were to: 1) examine PA levels and ST across frailty status; 2) identify any differences in PA/ST between ethnic and religious groups; and 3) qualitatively explore factors influencing PA among older (>= 60 years) migrant women (n = 60). PA/ST were assessed using accelerometry and frailty status using the frailty phenotype. Key factors influencing PA were explored via semi-structured interviews (n = 36) and analyzed using thematic analysis. Participants were highly sedentary irrespective of frailty status. Moderate-to-vigorous-physical activity (MVPA) was independently associated with frailty. Participants spent 69% of waking time in ST, with only 15% meeting current weekly PA recommendations. Health-related and socio-cultural factors were reported as common barriers to achieving PA recommendations. Maintaining independence, preventing physical decline and depression were key factors promoting PA. Understanding the challenges and needs of this population can help to inform strategies to promote PA and thus optimize physical function.
