Abstract

Purpose: To investigate the classification and characteristics of frailty transition in older adults over a 1-year period.

Method: A three-wave mailed cohort survey was conducted in a community setting. Data from 361 participants who answered all items were analyzed. Group-based multivariate trajectory modeling (GBTM) was used to classify frailty transitions over the three time points.

Results: GBTM revealed the best fit when participants were divided into four trajectory groups (G1: "worsened frailty after 1 year" [n = 94, 26%]; G2: "maintained frailty status" [n = 149, 41.3%]; G3: "improved frailty status" [n = 49, 13.6%]; and G4: "worsened frailty after 6 months" [n = 69, 19.1%]). Swallowing function was a significant association in participants in G1 and G3. Walking speed and exercise habits worsened between baseline and second surveys in G4.

Conclusion: Four frailty transition types were identified in the three-wave survey conducted over 1 year. Swallowing function was associated with the progression or improvement of frailty. [Research in Gerontological Nursing, 18(3), 146-153.].

老年人虚弱状态转变的分类和特征：基于群体的多元轨迹模型。

目的：探讨老年人1年内衰弱过渡的分类和特点。方法：在某社区进行三波邮寄队列调查。对361名回答了所有问题的参与者的数据进行了分析。使用基于组的多变量轨迹模型（GBTM）对三个时间点的脆弱性转变进行分类。结果：将参与者分为4个轨迹组(G1：“1年后虚弱恶化”[n = 94,26%]；G2：“维持虚弱状态”[n = 149, 41.3%]；G3：“虚弱状态改善”[n = 49, 13.6%]；G4：“6个月后虚弱恶化”[n = 69, 19.1%])。吞咽功能在G1和G3的参与者中有显著的关联。走路速度和运动习惯在基线和第二次调查期间有所恶化。结论：在为期一年的三波调查中，确定了四种虚弱过渡类型。吞咽功能与虚弱的进展或改善有关。[老年护理研究，xx(x)， xx-xx.]

期刊介绍： Research in Gerontological Nursing is a forum for disseminating peer-reviewed, interdisciplinary, cutting-edge gerontological nursing research and theory to investigators, educators, academicians, clinicians, and policymakers involved with older adults in all health care settings. The Journal accepts manuscripts reporting research, theory, integrative and systematic reviews, instrument development, and research methods with the aims of improving the wellness and quality of care of the older adult population. Theory papers should advance gerontological knowledge, and integrative reviews should provide an analysis of the state of the science and provide direction for future research.
