The multivariate analyses showed that child maltreatment (Adjusted OR = 2.13; 95% CI: 1.50, 3.01), weapon carrying (Adjusted OR = 3.31; 95% CI: 2.25, 4.86), binge drinking (Adjusted OR = 1.75; 95% CI: 1.21, 2.54), depression (Adjusted OR = 3.31; 95% CI: 2.71, 4.03), and impulsivity (Adjusted OR = 1.44; 95% CI: 1.22, 1.69) were significantly associated with co-occurring self-harm and suicide relative to those who reported neither (Table 2). Similarly, child maltreatment (Adjusted OR = 1.56; 95% CI: 1.24, 1.97), depression (Adjusted OR = 2.14; 95% CI: 1.85, 2.46), and impulsivity (Adjusted OR = 1.25; 95% CI: 1.10, 1.41) were associated with self-harm only. Weapon carrying (Adjusted OR = 2.16; 95% CI: 1.10, 4.23), binge drinking (Adjusted OR = 2.04; 95% CI: 1.15, 3.61), illicit drug use (Adjusted OR = 1.81; 95% CI: 1.07, 3.05), and depression (Adjusted OR = 2.52; 95% CI: 1.86, 3.40) were associated with suicide attempt only. Parental support (Adjusted OR = 0.50; 95% CI: 0.33, 0.76) was associated with a decreased likelihood of reporting co-occurring self-harm and suicide.
