Association of Daily Sitting Time and Leisure-Time Physical Activity with Sarcopenia Among Chinese Older Adults.
Article in Healthcare (Basel, Switzerland), 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 aimed to explore the independent and joint associations of daily sitting time and leisure-time physical activity (LTPA) with sarcopenia among older adults.
methodsThe participants were 847 community-dwelling adults aged 60 or older from Beijing and Shanghai, China. Sarcopenia was diagnosed based on the criteria established by the Asian Working Group for Sarcopenia (2019). Daily sitting time and LTPA were self-reported using the Physical Activity Scale for the Elderly (PASE). Logistics regression models were used to explore the associations between daily sitting time, LTPA, and sarcopenia. To examine joint associations, participants were classified based on daily sitting time and LTPA levels. Final models were adjusted for sociodemographic variables, lifestyle factors, and chronic conditions.
resultsProlonged sitting time and insufficient LTPA were independently associated with higher odds of sarcopenia. Among insufficiently active participants, sitting for 1-2 h, 2-4 h, and more than 4 h per day was associated with 5.52-fold (95% CI: 1.13-26.83), 6.69-fold (95% CI: 1.33-33.59), and 12.82-fold (95% CI: 2.75-59.85) increased odds of sarcopenia, respectively, compared to sitting for less than 1 h. For those meeting the physical activity guideline (≥150 min of LTPA per week), only sitting for more than 4 h per day was significantly associated with higher odds of sarcopenia (OR: 7.25, 95% CI: 1.99-26.36).
conclusionsProlonged sedentary behavior was associated with increased odds of sarcopenia. The higher odds of sarcopenia associated with more than 4 h daily sitting may not be offset by achieving the recommended levels of physical activity.
