To investigate the prevalence of the comprehensive frailty and its associated factors among community dwelling older adults.
A cross-sectional study.
Six community healthcare centres in Xi'an City, Northwest China.
A total of 2647 community dwelling older adults completed the study between March and August 2021.
The primary outcome was the prevalence of frailty, measured with the Comprehensive Frailty Assessment Instrument. The secondary outcomes were potential factors associated with frailty, measured with a social-demographic and health-related information sheet, the Short-Form Mini-Nutritional Assessment and the Pittsburgh Sleep Quality Index.
The participants averaged 27.77±10.13 in the total score of the Comprehensive Frailty Assessment Instrument. According to the cut-off points defining the classification of frailty, the majority of the participants were with mild (n=1478, 55.8%) or high (n=390, 14.8%) frailty. Multivariate stepwise linear regression analysis demonstrated that older age, lower educational level, empty nesters, higher level of self-perceived medical burden, abnormal body weight, physical inactivity, medication taking, increased number of clinic visit, undernutrition and poor sleep quality are associated with higher total score in the Comprehensive Frailty Assessment Instrument, indicating higher level of frailty. Multivariate multinomial logistic regression analysis exhibited similar findings but further captured female gender as a risk factor for the presence of mild and high frailty compared with no-low frailty.
The prevalence of the comprehensive frailty and frailty in the physiological, psychological, social and environmental domains is high. A variety of social-demographic, health-related and behavioural factors were associated with the comprehensive frailty. Further investigations on frailty prevalence and its associated factors based on comprehensive assessments are desirable.
调查社区居住老年人综合虚弱的流行情况及其相关因素。
横断面研究。
中国西北部西安市的 6 个社区医疗中心。
共有 2647 名社区居住老年人在 2021 年 3 月至 8 月期间完成了研究。
主要结果是使用综合虚弱评估工具测量的虚弱的流行率。次要结果是使用社会人口统计学和健康相关信息表、简短的迷你营养评估和匹兹堡睡眠质量指数测量的与虚弱相关的潜在因素。
参与者的综合虚弱评估工具总分平均为 27.77±10.13。根据定义虚弱分类的截断点，大多数参与者有轻度（n=1478，55.8%）或高度（n=390，14.8%）虚弱。多变量逐步线性回归分析表明，年龄较大、教育水平较低、空巢老人、自我感知医疗负担较高、体重异常、身体活动不足、服药、就诊次数增加、营养不良和睡眠质量差与综合虚弱评估工具的总分较高相关，表明虚弱程度较高。多变量多项逻辑回归分析得出了类似的发现，但进一步表明女性性别与轻度和高度虚弱的存在相关，而不是与无低度虚弱相关。
综合虚弱和生理、心理、社会和环境领域虚弱的流行率较高。各种社会人口统计学、健康相关和行为因素与综合虚弱有关。基于综合评估进一步研究虚弱的流行率及其相关因素是可取的。
