To investigate the association between sedentary behaviour (SB), physical activity (PA), and frailty and frailty subdomains in community-dwelling older women.
Frailty is associated with numerous adverse health outcomes in older people, and women had a higher prevalence than men. However, older adults may face different health risks due to different combinations of frailty subdomains; therefore, specific studies on frailty subdomains are needed.
A cross-sectional study guided by the STROBE.
In total, 1099 community-dwelling older Chinese women (60-70 years) were included. SB and PA were objectively obtained using a validated triaxial accelerometer. Frailty was defined using the Fried Phenotype (FP) Model.
After adjusting for confounders, a significant association was found between SB, PA and the prevalence of frailty. The optimal cut-off values of total SB time, light PA (LPA) time, and moderate-to-vigorous PA (MVPA) time to discriminate between frailty and non-frailty were 625.4 min/day, 379.3 min/day and 20.1 min/day, respectively. For frailty subdomains, total SB time was positively associated with low PA. When it comes to total LPA time, the association with low PA was negative. Total MVPA time was significantly and negatively associated with exhaustion, weakness, slowness and low PA, and the optimal cutoff value was 24.4 min/day, 26 min/day, 29.5 min/day and 20.8 min/day, respectively.
Effective management of frailty requires consideration of different combinations of frailty subdomains. Increasing MVPA and limiting SB may help deal with frailty for community-dwelling older Chinese women. Additional research is needed to determine whether PA are useful for prevention of frailty.
The results of this study could help caregivers provide professional and specific physical activity guidance for order women, who are on a risk of or already suffered frailty.
探讨社区居住老年女性久坐行为（SB）、身体活动（PA）与衰弱及衰弱亚领域之间的关联。
衰弱与老年人众多不良健康结局相关，且女性患病率高于男性。然而，由于衰弱亚领域的不同组合，老年人可能面临不同的健康风险；因此，需要针对衰弱亚领域进行具体研究。
一项遵循STROBE指南的横断面研究。
共纳入1099名社区居住的中国老年女性（60 - 70岁）。使用经过验证的三轴加速度计客观获取SB和PA数据。采用Fried表型（FP）模型定义衰弱。
在调整混杂因素后，发现SB、PA与衰弱患病率之间存在显著关联。区分衰弱与非衰弱的总SB时间、轻度PA（LPA）时间和中度至剧烈PA（MVPA）时间的最佳截断值分别为625.4分钟/天、379.3分钟/天和20.1分钟/天。对于衰弱亚领域，总SB时间与低PA呈正相关。就总LPA时间而言，与低PA的关联为负相关。总MVPA时间与疲惫、虚弱、行动迟缓及低PA显著负相关，最佳截断值分别为24.4分钟/天、26分钟/天、29.5分钟/天和20.8分钟/天。
有效管理衰弱需要考虑衰弱亚领域的不同组合情况。增加MVPA并限制SB可能有助于应对社区居住的中国老年女性的衰弱问题。需要进一步研究以确定PA是否对预防衰弱有用。
本研究结果可帮助护理人员为有衰弱风险或已患衰弱的老年女性提供专业且具体的身体活动指导。
