Abstract

This study aims to examine the trajectory of older adults' cognitive function over time and identify its predictors. Based on the model of neuroplasticity and cognitive reserve, participants' general characteristics as well as their physical, mental, and social factors were included as predictors of cognitive function. A latent growth model analysis was used to examine the trajectory of cognitive function and its predictors. The analysis of the unconditional model revealed that older adults' cognitive function significantly decreased over time. The rate of cognitive decline was significantly related with age, current smoking status, depression scores, number of social activities, time spent in group cognitive activities, and number of individual cognitive activities. The findings identified predictors affecting initial cognitive function and the rate of cognitive decline in older adults. The rate of cognitive decline varies widely among individuals. Identifying these differences is essential for effectively tailoring interventions that address individual needs.

韩国老年人8年的认知功能轨迹和预测因素：一项全国面板数据分析。

本研究旨在研究老年人认知功能随时间的变化轨迹，并确定其预测因素。基于神经可塑性和认知储备模型，将被试的一般特征以及生理、心理和社会因素作为认知功能的预测因子。使用潜在增长模型分析来检查认知功能的轨迹及其预测因子。对无条件模型的分析显示，随着时间的推移，老年人的认知功能显著下降。认知能力下降的速度与年龄、当前吸烟状况、抑郁评分、社会活动次数、群体认知活动时间和个人认知活动次数显著相关。研究结果确定了影响老年人初始认知功能和认知能力下降速度的预测因素。认知能力下降的速度因人而异。识别这些差异对于有效地定制针对个人需求的干预措施至关重要。

期刊介绍： The Journal of Applied Gerontology (JAG) is the official journal of the Southern Gerontological Society. It features articles that focus on research applications intended to improve the quality of life of older persons or to enhance our understanding of age-related issues that will eventually lead to such outcomes. We construe application broadly and encourage contributions across a range of applications toward those foci, including interventions, methodology, policy, and theory. Manuscripts from all disciplines represented in gerontology are welcome. Because the circulation and intended audience of JAG is global, contributions from international authors are encouraged.
