We applied a person-oriented approach and used latent class linear mixed models to identify sleep trajectories that explain memory, concentration, and learning ability problems after retirement.
Data consist of prospective surveys from four phases of the Helsinki Health Study between 2000-2017 (n = 3748, aged 55-77 years, 80% women). Multinomial regression was used to examine the associations between sleep trajectories and cognitive function, adjusting for sociodemographic, health-related behavior, and health factor covariates.
Among statutory retirees, three latent group trajectories of insomnia-related symptoms were identified: stable low, decreasing, and increasing. Among those who had retired for disability reasons, we identified one additional latent group trajectory: stable high. Insomnia symptoms were associated with worse cognitive function.
Early detection of insomnia symptoms would be a potential intervention point to improve both sleep quality and prevent cognitive decline in later life. However, intervention studies are needed.
我们采用个体导向的方法，运用潜在类别线性混合模型，确定解释退休后记忆、注意力和学习能力问题的睡眠轨迹。
数据来自于 2000-2017 年赫尔辛基健康研究的四个阶段的前瞻性调查（n=3748，年龄 55-77 岁，80%为女性）。使用多项回归分析来检验睡眠轨迹与认知功能之间的关联，同时调整了社会人口统计学、与健康相关的行为和健康因素的协变量。
在法定退休者中，确定了三种与失眠相关症状的潜在群组轨迹：稳定低、下降和增加。在因残疾而退休的人群中，我们确定了另一种潜在群组轨迹：稳定高。失眠症状与认知功能下降有关。
早期发现失眠症状可能是改善睡眠质量和预防晚年认知能力下降的潜在干预点。但是，需要进行干预研究。
