Mediating effects of social and intellectual activities on cognitive decline caused by hearing loss: insights from the China health and retirement longitudinal study (CHARLS).
Article in BMC neurology, 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
backgroundHearing impairment is increasingly recognized as a pivotal determinant of cognitive function. As the global population ages, the urgency to pinpoint and leverage modifiable risk factors to alleviate cognitive deterioration intensifies.
objectiveThis investigation seeks to delineate the correlation between auditory deficits and cognitive capabilities, especially examining the intermediary influence of social and intellectual engagements on this dynamic.
methodsThis research utilized cross-sectional data from the 2015 iteration of the China Health and Retirement Longitudinal Study (CHARLS). A multiple linear regression model was utilized to assess the relationship between hearing loss and cognitive function. Furthermore, mediation analysis was performed to investigate the mediating role of social and intellectual activities in this association.
resultsThe analysis revealed a pronounced negative association between hearing loss and cognitive function (B = -0.531, 95% CI: -0.658 to -0.390). After adjusting for social and intellectual activities, hearing loss was found to be 92.15% of the total observed effect on cognitive decline. In the mediation analysis, social and intellectual activities were found to mediate approximately 7.85% of the relationship between hearing loss and cognitive decline.
conclusionThe findings highlight the association between hearing loss and reduced cognitive function and suggest that greater engagement in social and intellectual activities may be related to better cognitive outcomes. These results support the potential value of enhancing hearing screening and promoting activity engagement among older adults.
