Assessing the Level and Determinants of Active Aging in China: An LDA-Based Topic Modeling Approach.
Article in Risk management and healthcare policy, 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: While the concept of active aging has been extensively studied in high-income countries, China faces distinct demographic challenges, including a rapidly growing elderly population, accelerated aging, and aging prior to widespread economic prosperity. These trends highlight the urgent need for a context-specific conceptual and evaluative framework to measure active aging, tailored to China's socio-cultural and economic realities. Methods: This study employs the Latent Dirichlet Allocation (LDA) topic model to construct a multidimensional indicator system for measuring active aging among older adults in China. Drawing on five waves of nationally representative panel data from the China Health and Retirement Longitudinal Study (CHARLS), spanning 2011 to 2020, we evaluate individual-level active aging scores using a quantitatively derived framework. Results: The measurement system consists of six core dimensions and 21 indicators: (1) physical health and functional capacity, (2) psychological well-being and life satisfaction, (3) family caregiving and social security, (4) economic security and intergenerational support, (5) social participation and enabling environments, and (6) lifelong learning and self-management. All scale-based measures demonstrated acceptable internal consistency (Cronbach's alpha ≥ 0.70). The average active aging score among the full sample was 0.4912±0.0907. Conclusion: Active aging levels in China have shown consistent improvements over the observation period, with the most pronounced gains in the eastern region. The central region has seen a narrowing of differences, while the eastern, northeastern, and western parts of the country have seen a widening of differences. Key positive correlates of active aging include educational attainment, urban residence, male gender, alcohol consumption, and being married. Negative associations were found for older age, geographic region, presence of chronic conditions, number of surviving children, and smoking. Among these, education attainment, urban-rural status, age and gender emerged as the most influential factors.
