Urban-rural social security, adult children's layoffs and older parents' health.
Article in Frontiers in public health, 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
Objective: Aging population and rising unemployment risks have emerged as dual challenges for governments worldwide. Using China's 1990s state-owned enterprise layoffs as a natural experiment, we examine causal evidence on how adult children's unemployment affects older parents' health. We particularly analyze how urban-rural social security moderates these effects. Methods: Using data from the China Health and Nutrition Survey 1991-2006, we construct three health outcome dimensions for older parents: disease status, daily functional abilities (physical function and instrumental activities of daily living), and body mass index. Econometric analysis uses a two-way fixed effects model and a causal forest model. Results: The layoffs of adult children significantly increased older parents' morbidity risk. Due to disparities in the social security system between urban and rural household registration (hukou), this effect primarily increased health risks-including higher probability of disease, increased risk of hypertension, limitations in daily activities, and underweight conditions-among rural-hukou older parents living in urban areas. In contrast, layoffs of adult children showed no measurable impact on urban-hukou older parents. Mechanistically, layoffs did not reduce daily care provided by children to their parents, but rather diminished household income. Moreover, layoffs of adult children reduced older parents' healthcare utilization and lowered their nutritional intake. Rural-hukou older parents living in urban areas were most affected, with reduced protein and fat consumption. Conclusion: The reduction in family resources caused by adult children's unemployment is detrimental to older parents' health. The social security system serves as a vital safety net for protecting the health of older populations. Strengthening social security is an essential policy complement to mitigate welfare losses in families affected by unemployment.
