Adj RR, adjusted relative risk; Ref, reference group; —, not calculated for reference group.

^aAdjusted relative risk estimated using a separate Poisson regression model with robust standard errors for each measure. All models adjusted for pubertal developmental stage, age at enrollment, and recruitment school.

^bSocial network gang exposure was defined based on participant report that at least some of their close friends or the people they spend time with now were in or affiliated with a gang.

^*P ≤ .05.

^**P ≤ .01.
