This study investigates the association between residential greenspace structures and frailty in older Chinese adults. Using data from the China Longitudinal Healthy Longevity Survey (CLHLS) and satellite-derived greenspace indices (largest patch index (LPI), shape index, cohesion index), cross-sectional and longitudinal analyses were conducted. Cross-sectional analyses revealed negative dose-response relationships between greenspace structures and frailty, particularly in females, centenarians, illiterate individuals, city residents, unmarried individuals, and those with increased frailty. However, longitudinal analyses did not show a significant association. The study suggests that higher levels of greenness structures may be related to lower frailty, although further research is needed to confirm a clear longitudinal benefit.
