Association between night sleep duration and depression among Chinese elderly: evidence from the China health and retirement longitudinal study 2020.
Article in BMC geriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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 association between night sleep duration and depression has been documented in previous studies, but remains controversial. This study aims to explore the relationship between depression and nighttime sleep time in Chinese elderly people and its influencing factors.
methodsThe data originated from the China Health and Retirement Longitudinal Study 2020 (CHARLS 2020), including 8,365 residents aged at least 60. The logistic regression analysis model was used to analyze the depression-related factors, and the restricted cubic spline (RCS) was used to examine the dose-response relationship between night sleep duration and depression.
resultsIn 2020, the prevalence of depression among the Chinese elderly was 41.02%. Females, living in rural areas, having no spouse/partner, receiving medical treatment within 1 month, experiencing physical pain, perceiving poor health status, and being dissatisfied with the relationship with children were risk factors for depression in the elderly. The relationship between night sleep duration and depression differs by gender. In males, shorter sleep (less than 6 h) raises the risk of depression; in females, it shows a U-shaped relationship. The RCS indicated a non-linear dose-response (male χ2 = 30.56, P < 0.001; female χ2 = 32.26, P < 0.001). After stratification a non-linear relationship was still present (P < 0.05).
conclusionThe impact of night sleep duration on depression is different between male and female. For males, less than 6 h of sleep is a risk factor, and more than 6 h has no significance, while for females, a U-shape exists, with too little (less than 6 h) or too much (9 h or more) are both risk factors for depression.
