Note: Analyses included all children with a neighborhood park space (n=73).
a
Single predictor model with no adjustment for demographics
b
The fully adjusted models controlled for child’s age, gender, race/ethnicity, and annual household income.
c
The Euclidian distance between residence and the nearest park boundary
d
The Normalized Difference Vegetation Index (NDVI) was used to estimate the average level of greenness for parks within the neighborhood buffer. NDVI was derived from LANDSAT satellite imagery data and is an indicator of level of vegetation.
e
Total park area and number of parks that intersect the area within 500 meters of a child’s home
