Longitudinal predictive analysis of sleep quality changes and subsequent depressive symptoms in older Chinese Adults.
Article in BMC geriatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe relationship between changes in sleep quality and the risk of developing depressive symptoms remains inconclusive, particularly among older adults. This study aims to examine the association between alterations in sleep quality and subsequent occurrence of depressive symptoms in older adults in China.
methodsWe analyzed data from the 2011,2014 and 2018 waves of Chinese Longitudinal Healthy Longevity Survey (CLHLS), a large-scale nationwide cohort study.Self reported sleep quality were evaluated. Based on changes in sleep quality scores over a 3-year follow-up period (from T1 to T2), participants were divided into four groups. The Center for Epidemiologic Studies Depression Scale (CES-D-10) was used to assess depression symptoms in T3. A total of 2129 participants were included in the analysis. Logistic regression models were employed to assess the association of sleep quality changes with future depressive symptoms, adjusting for demographics, health status, health behavior, sleep duration and initial depressive symptoms.
resultsAfter adjusting for covariable factors, both continuous and categorical sleep quality at T1 were significantly correlated with depressive symptoms over the course of follow-up. Participants with poor sleep quality at either T1 or T2, as well as those with persistent poor sleep quality from T1 to T2, exhibited higher adjusted odds ratios (ORs) for future depressive symptoms: 1.77(1.20–2.60), 1.83(1.29–2.58) and 2.95(1.88–4.64), respectively. The deterioration of sleep quality during the two waves was linked to an increase in the risk of depressive symptoms in subsequent wave. The association between participants with poor sleep quality at both T1 and T2 and future depressive symptoms was more marked among those who never participated in leisure activities.
conclusionsThe deterioration of sleep quality heightened the risk of future depressive symptoms among older people in China. The association was more marked in those lack of leisure activity participation. Our study supports the predictive role of sleep quality monitoring in depressive symptoms.
