Abstract

Objectives

The relationship between sleep duration and depressive symptoms remains controversial in middle-aged and older adults. The aim of this study is to investigate the relationship of sleep duration trajectories with depressive symptoms and conduct further exploration through network analysis.

Methods

Based on the five waves of data on 8681 middle-aged and older adults from 2011 to 2020 in the China Health and Retirement Longitudinal Study database, group-based trajectory modeling was employed to depict their sleep trajectories. Binary logistic regression and network analysis were conducted to assess the relationship between sleep trajectories and depressive symptoms. Subgroup analysis was performed based on age (< 60, ≥ 60 years).

Results

The study identified three nighttime sleep duration trajectories, three daytime nap duration trajectories, and nine combined trajectories. People with initially low or moderate then decreasing nighttime sleep duration trajectory were more likely to have depressive symptoms compared with those with persistently recommended trajectory. And people with the combination of initially low then decreasing nighttime sleep and initially moderate or low then increasing daytime nap duration trajectories and the combination of initially moderate then decreasing nighttime sleep and initially high then increasing daytime nap duration trajectories were prone to have depressive symptoms compared with the combination of persistently recommended nighttime sleep and initially moderate then increasing daytime nap duration trajectories. The association between sleep trajectories and depressive symptoms may be modified by age groups (< 60 vs. ≥ 60 years). In network analyses, “felt depressed” was the most central item, and there were structural differences across different sleep duration trajectory networks.

Conclusions

Taking naps could offset the risk of depressive symptoms for people who lacked sleep at night. Developing different intervention strategies based on different sleep trajectories might help alleviate the onset of depressive symptoms.

中老年人睡眠持续时间轨迹与抑郁症状之间的关系：一项全国代表性调查的结果

目的在中老年人群中，睡眠时间与抑郁症状之间的关系仍存在争议。本研究旨在探讨睡眠持续时间轨迹与抑郁症状的关系，并通过网络分析进行进一步探索。方法基于2011 - 2020年中国健康与退休纵向研究数据库中8681名中老年人的5波数据，采用基于群体的轨迹建模方法对其睡眠轨迹进行刻画。采用二元逻辑回归和网络分析来评估睡眠轨迹与抑郁症状之间的关系。根据年龄（60岁，≥60岁）进行亚组分析。研究确定了三种夜间睡眠持续时间轨迹，三种白天小睡持续时间轨迹和九种组合轨迹。与那些持续推荐的睡眠轨迹相比，最初睡眠时间较低或中等然后逐渐减少的人更有可能出现抑郁症状。与坚持推荐夜间睡眠和最初适度然后白天小睡时间增加的轨迹相结合的人最初夜间睡眠时间少然后减少最初夜间睡眠时间多然后白天小睡时间增加的轨迹相结合的人更容易出现抑郁症状与坚持推荐夜间睡眠和最初适度然后白天小睡时间增加的轨迹相比较。睡眠轨迹与抑郁症状之间的关联可能因年龄组而改变（60岁vs.≥60岁）。在网络分析中，“感到抑郁”是最核心的项目，并且在不同的睡眠持续时间轨迹网络中存在结构差异。结论：小睡可以抵消夜间睡眠不足的人出现抑郁症状的风险。根据不同的睡眠轨迹制定不同的干预策略可能有助于减轻抑郁症状的发作。

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.
