本研究采用固定效应logistic和Poisson回归模型，在新西兰年轻人的出生队列中研究了失业与自杀行为（自杀意念和自杀未遂）之间的关联。数据收集了16-25岁的失业和自杀行为的年度数据。在所有年龄段，失业风险的增加与自杀意念（p <0.0001）和自杀企图（p <0.0001）的风险增加有关。在调整固定效应和时间动态协变量后，失业和自杀意念之间的关联降低到边缘显著性（p <0.05）。10），而失业与自杀企图之间的关联在统计学上并不显著（p >. 10）。调整后，那些在给定年份经历6个月或更长时间失业的人的自杀意念的几率是1.43倍（95% CI：0.96至2.16），自杀企图的比率是1.72倍（95% CI：0.89至3.32），比那些没有失业的人高。虽然失业与自杀行为风险的适度增加有关，但这种关联在很大程度上是由混杂因素解释的。
This study examined the association between exposure to unemployment and suicidal behaviors (suicidal ideation and attempted suicide) in a birth cohort of New Zealand young adults using fixed-effects logistic and Poisson regression models. Data were gathered on unemployment and suicidal behaviors at annual periods from ages 16-25 years. At all ages increasing exposure to unemployment was associated with increased risks of suicidal ideation (p < .0001) and number of suicide attempts (p < .0001). Following adjustment for fixed effects and time-dynamic covariates, associations between unemployment and suicidal ideation reduced to marginal significance (p < . 10), while the association between unemployment and suicide attempts was not statistically significant (p >. 10). After adjustment, those experiencing 6 or more months of unemployment in a given year had odds of suicidal ideation that were 1.43 (95% CI: .96 to 2.16) times higher, and rates of suicide attempts that were 1.72 (95% CI: .89 to 3.32) times higher, than those who were not exposed to unemployment. Although unemployment was associated with moderate increases in risks of suicidal behaviors, much of this association was explained by confounding factors.
