Effects of work cessation on cognitive functioning in rural older adults in China: a cross-sectional study based on CHARLS.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesThis study investigated the effects of work cessation on cognitive function among older adults in rural China. Given that cognitive disorders affect 6.04% of individuals aged 60 and above-with higher prevalence in rural areas-understanding this relationship is critical.
designA cross-sectional study was employed, using data from the 2020 wave of the China Health and Retirement Longitudinal Study (CHARLS). Regression analysis assessed the impact of work cessation on cognitive function and the moderating effects of social activities, health behaviours and internet use.
settingData were collected from 150 districts, 450 villages, and urban community units in China.
participantsThe study included 6,318 participants, with 4,045 currently employed and 2,273 no longer working.
main outcome measuresCognitive function was evaluated using measures of mathematical computation, temporal and image cognition, and situational memory was tested through 20 memory-related questions. Explanatory variables included work cessation status, while moderating variables encompassed social activities, health behaviours (smoking and alcohol consumption) and internet use.
resultsWork cessation has a negative impact on cognitive function, particularly situational memory and overall cognitive ability. Stopping work was associated with a decrease in cognitive functioning by 0.796 SD (p<0.01), a reduction in situational memory capacity by 1.083 SD (p<0.01) and a decline in total cognitive ability by 1.879 SD (p<0.01). However, more social activities, better health behaviours (eg, quitting smoking) and internet use can alleviate the impact. Seniors with high social activity levels showed an increase in cognitive functioning by 0.375 SD (p<0.01), while those who drank less alcohol had a 0.598 SD improvement in cognitive functioning (p<0.01). Internet use improved cognitive function by 1.265 SD (p<0.01).
conclusionWork cessation significantly reduced cognitive function in rural Chinese older adults. Leisure activities can mitigate this decline, but they often lack quality and diversity. Health behaviour improvements show heterogeneity, and internet use mitigates cognitive decline despite urban-rural digital gaps. To protect rural older adults' cognitive function, policies promoting flexible employment, enhanced recreational infrastructure, health outreach and bridging digital divides are proposed.
