Age (Tanner) refers to Tanner stage nested in age

B = unstandardized coefficient

SE = standard error

β= standardized coefficient

Neighborhood Index consisted of z-score tabulations of percent unemployment, poverty, single female headed households with dependent children, and percent vacant housing

Significance levels were set at

^†p<.10,

^*p<.05;

^**p<.01;

^***p<.001

Full model was significant at p<.001
