Built Environment and Loneliness Trajectories Among Middle-Aged and Older Adults in China.
Article in Journal of urban health : bulletin of the New York Academy of Medicine, 2026. 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
Loneliness is increasingly recognized as a critical public health concern, yet evidence on the associations between long-term residential conditions and loneliness trajectories remains limited, particularly in developing countries. Using nationally representative longitudinal data from the China Health and Retirement Longitudinal Study (CHARLS), this study identified loneliness trajectories among middle-aged and older adults and examined the associations between housing and neighborhood characteristics and trajectory membership. Growth mixture modeling (GMM) was applied to identify latent trajectory classes, and multinomial logistic regression was used to estimate these associations. We identified three distinct trajectories: stable-low (70.6%), increasing (17.6%), and decreasing (11.9%). Statistically significant associations with trajectory membership were more common for individual-level characteristics than for housing and neighborhood characteristics. Among the latter, certain housing structure types and higher housing quality were associated with a greater likelihood of belonging to the stable-low trajectory, whereas declines in housing quality were associated with membership in the increasing trajectory. Larger residential land area was associated with the decreasing trajectory among rural residents, while associations with floor area varied across demographic and regional groups. In addition, greater availability of neighborhood amenities and better transportation conditions were associated with stable-low trajectory membership among rural residents. Overall, these findings extend existing research by linking built environment characteristics to longitudinal patterns of loneliness. By identifying vulnerable subpopulations and highlighting the potential relevance of housing and neighborhood conditions, this study provides evidence that may inform future urban planning, community development, and mental health prevention strategies.
