From: Built and socioeconomic environments: patterning and associations with physical activity in U.S. adolescents

  Homogenous landscape Intensity (pay facilities) Intensity (public facilities)
Patch size variability 0.98 -- --
Contagion index 0.90 -- --
Simpson's diversity index -0.90 2 -- --
Mean patch size 0.87 -- --
Land patch density -0.82 -- --
Perimeter-fractal dimension -0.81 -- --
Intersection density -0.20 0.48 0.33

  1. 1 National Longitudinal Study of Adolescent Health, Wave I (1995-96), n = 18,294. Obtained from exploratory factor analysis using a principal factors estimator and oblique oblimin (gamma = 0) rotation. Unweighted correlations with non-diverse landscape were -0.03 and -0.02 for intensity (pay facilities) and intensity (public facilities), respectively; and 0.58 between intensity (pay facilities) and intensity (public facilities).
  2. 2 Indicator variable(s) used to represent corresponding factor in Tables 8 & 9.
  3. --For clarity, loadings with absolute value <0.2 were omitted
