Prevalence and risk factors of loneliness among older adults in China: a nationally representative study.
Article in BMC geriatrics, 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
backgroundLoneliness is increasingly recognized as a significant public health concern, yet limited research has examined its prevalence and risk factors among older adults in China.
methodsThis study investigated the prevalence and risk factors of loneliness among older adults in China using data from the 2018 China Longitudinal Aging Social Survey (CLASS), a nationally representative study. The sample included 9,951 participants aged 60 and older (mean age = 71.3 years, SD = 7.3; 49.94% female). Loneliness was measured using the Chinese version of the three-item UCLA Loneliness Scale, which was validated as a reliable and effective tool for assessing loneliness in this population.
resultsOverall, 19.6% of older Chinese adults reported experiencing loneliness. Logistic regression models identified demographic factors (older age, living in rural areas, lower income, and lower education), health factors (depressive symptoms and functional limitations), and social factors (living alone, reduced social support and social participation) as being associated with loneliness. Among these, higher levels of depressive symptoms (OR 1.29, 95% CI 1.26–1.32), living alone (OR 1.37, 95% CI 1.14–1.65), and reduced social participation (OR 1.51, 95% CI 1.35–1.71) emerged as the strongest predictors of loneliness.
conclusionsThe findings highlight the high prevalence of loneliness among older Chinese adults and underscore the need for targeted interventions, especially for individuals with depressive symptoms, those living alone, or those with limited social engagement.
