Abstract

Objectives

This study examined the age trajectories of mental and cognitive health from midlife to older adulthood, and how age and gender impacted mental and cognitive health change across age cohorts.

Methods

Multilevel modeling was used to analyze the panel data on cognitive function, life satisfaction, and depressive symptoms from the 1996-2011 Taiwan Longitudinal Study on Aging (N = 5131).

Results

Cognitive function gradually declined with chronological age (β_age = −0.041, p < 0.001), and declined faster in earlier-born cohorts (β_{age*cohort 7} = −0.168, p < 0.001). Life satisfaction showed the opposite effect with age and cohort: while earlier-born cohorts reported lower life satisfaction (β_{cohort 7} = −0.498, p < 0.05), life satisfaction increased with chronological age (β_age = 0.015, p < 0.05). Older adults reported more depressive symptoms, but this phenomenon was only significantly associated with age cohort (β_{cohort 7} = 3.530, p < 0.001). Widened differences between men and women in life satisfaction and depressive symptoms were associated with age cohort but not chronological age per se.

Conclusions

Men and later-born cohorts experienced significantly better mental and cognitive health than women and earlier-born cohorts. Age- and gender-related changes in mental and cognitive health in later life should be considered within the socio-culturally contextualized birth cohort.

从中年到老年心理与认知健康的年龄轨迹：台湾群体与性别角色的检验

目的本研究考察了从中年到老年心理和认知健康的年龄轨迹，以及年龄和性别如何影响各年龄段人群的心理和认知健康变化。方法采用多水平模型分析1996-2011年台湾老龄化纵向研究（N = 5131）的认知功能、生活满意度和抑郁症状的面板数据。结果认知功能随年龄增长逐渐下降(βage = - 0.041, p <；0.001)，在较早出生的队列中下降更快(β年龄*队列7 = - 0.168,p <；0.001)。生活满意度与年龄和队列相反：较早出生的队列报告的生活满意度较低(β队列7 = - 0.498,p <；0.05)，生活满意度随年龄增长而增加(βage = 0.015, p <；0.05)。老年人报告的抑郁症状更多，但这一现象仅与年龄队列显著相关(β队列7 = 3.530,p <；0.001)。男女在生活满意度和抑郁症状方面的差异扩大与年龄群有关，但与实际年龄本身无关。结论：男性和晚出生人群的心理和认知健康状况明显好于女性和早出生人群。在社会文化背景下的出生队列中，应考虑到老年生活中与年龄和性别相关的心理和认知健康变化。

期刊介绍： The rapidly increasing world population of aged people has led to a growing need to focus attention on the problems of mental disorder in late life. The aim of the Journal is to communicate the results of original research in the causes, treatment and care of all forms of mental disorder which affect the elderly. The Journal is of interest to psychiatrists, psychologists, social scientists, nurses and others engaged in therapeutic professions, together with general neurobiological researchers. The Journal provides an international perspective on the important issue of geriatric psychiatry, and contributions are published from countries throughout the world. Topics covered include epidemiology of mental disorders in old age, clinical aetiological research, post-mortem pathological and neurochemical studies, treatment trials and evaluation of geriatric psychiatry services.
