Green space activity exposure and linear/non-linear associations with multidimensional health among older adults: evidence from a generalized additive model
A cross-sectional survey examines how green space activity exposure affects health in older adults, highlighting important implications for urban planning.
Key Points
The study aims to explore the complex relationships between green space activity exposure and various dimensions of health in older adults.
Conducted a cross-sectional survey with 744 older adults across five urban parks.
Collected data on weekly green space activity exposure frequency, duration, intensity, and total activity volume.
Assessed multidimensional health using validated self-reported instruments.
Utilized generalized additive models to analyze associations and identify potential thresholds.
Revealed non-linear associations between green space activity exposure parameters and all four health dimensions.
Identified pronounced associations around 7–12 sessions per week and 15–22 hours of activity.
Moderate intensity of 2.5–4.1 METs showed significant positive health impacts.
Social health indicated a consistent positive linear association with increasing levels of green space activity exposure.
