PM_2.5= particulate matter < 2.5 micrometers; BMI=body mass index; ANS=autonomic nervous system; HRV=heart rate variability; SCL=skin conductance level. Boys were coded as 0 and girls were coded as 1. European American participants were coded as 0 and all other participants were coded as 1. Full information maximum likelihood was used to take advantage of the full sample (N=144) to estimate all correlations.
