TABLE 3—

Analyses With Interaction Terms of Risk Factors for Suicidal Ideation and Suicide Attempts in the Past Year Among Adolescents and Young Adults: National Longitudinal Study of Adolescent Health, 2001–2002

Non-LGB vs LGB Respondents	Exponent of Interaction Terma (95% CI)
Suicidal Ideation
Problem drinkingb	1.21 (0.59, 2.51)
Problem drug useb	2.80 (1.19, 6.57)*
Depressionc	0.97 (0.86, 1.08)
Suicide attempts
Problem drinkingb	1.31 (0.27, 6.38)
Problem drug useb	2.68 (0.65, 11.45)
Depressionc	1.15 (1.01, 1.31)*

Note. LGB = lesbian, gay, or bisexual; CI = confidence interval. Adjusted for age, race, and gender.

^aExponent of interaction term =OR_non-LGB / OR_LGB.

^bProblem drinking and problem drug use in the preceding 12 months were coded as present if the respondents answered yes to any of the 6 items in each domain. Dichotomous; reference group = no problem drinking.

^cDepression was measured in the adolescent health survey with 9 items from the Center for Epidemiologic Studies Depression Scale.20 For every 1-unit increase in the score, the odds of suicidal ideation or suicide attempts increased by the amount shown (e.g., a 1-unit increase in the score increased the likelihood of reporting suicidal ideation by 25% among the non-LGB respondents and 29% among the LGB respondents).
