Grandparental childcare and physical activity among rural older adults in China: evidence from the China longitudinal aging social survey.

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: Population aging in rural China is increasing, making the promotion of health among rural older adults an urgent issue. Physical activity is a crucial way to maintain health in later life and has attracted significant attention from researchers both domestically and internationally. Grandparental childcare, as an important form of intergenerational family support, may play a key role in influencing older adults' participation in physical activity. However, there is limited empirical evidence on the mechanisms that explain these effects. This study explores the association between grandparental childcare and physical activity among rural older adults and further examines potential mechanisms underlying this relationship. Methods: The study used data from 6,188 respondents in the 2023 China Longitudinal Aging Social Survey. After controlling for sociodemographic factors such as gender, age, education, self-rated health, and income, a binary logistic regression model was applied to examine the association between grandparental childcare and physical activity. Results: Descriptive statistics show that 60% of rural older adults provide grandparental childcare, and 44.2% participate in physical activity. The regression results indicate that providing grandparental childcare is associated with a 6.66-percentage-point higher probability of engaging in physical activity. Heterogeneity analysis reveals that this association is stronger among women and older adults aged 60-69. Conclusion: Grandparental childcare is significantly associated with participation in physical activity among rural older adults, with stronger associations observed among women and younger older adults. It is recommended that rural communities integrate physical activity opportunities into daily caregiving contexts, make better use of existing public spaces, and provide health education and caregiver support for older adults who provide grandparental childcare. These initiatives can help support caregiving responsibilities and contribute to healthy aging among rural older adults.
