The cognitive consequences of fear of falling: assessing the mediating role of social engagement and physical activity.
Article in Innovation in aging, 2025. 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
Background and Objectives: Cognitive function is crucial for older adults' independence and quality of life. This study investigated the longitudinal relationship between fear of falling and cognitive function using data from the Korean Longitudinal Study of Ageing. Specifically, it examined whether social engagement (regular informal contact and social activities) and physical activity mediate the impact of fear of falling on cognitive function, informing targeted strategies to mitigate cognitive decline. Research Design and Methods: This study analyzed seven waves (2006 to 2018) of a nationally representative longitudinal survey involving 3,453 older adults in Korea. To minimize omitted variable bias, the research applied ordinary least squares models with lagged dependent variables and conducted Sobel-Goodman mediation tests for additional insights. Results: Developing a fear of falling over 2 years is negatively associated with cognitive function. Additionally, although fear of falling negatively impacts social activities and informal contacts, it does not significantly alter physical activity. Mediation analyses show that reduced social activities account for 31% of the cognitive decline associated with fear of falling, compared to 15% for informal social contacts. These findings highlight active social participation as a key factor in protecting cognitive health. Physical activity did not mediate this relationship. Discussion and Implications: Interventions should prioritize enhancing social engagement to mitigate cognitive decline related to fear of falling. Facilitating active community participation can effectively support cognitive health and overall well-being in aging populations.
