Abstract

Suicide rates in Mexico have been rising steadily for several decades. This study examined the relationship of depressed mood and antisocial behavior problems with thoughts of death, suicide plans and attempts. Data from 22,966 individuals who participated in a population-based nationally-representative survey in Mexico were analyzed. After adjusting for covariates, all odds ratios for thoughts of death and suicidal behaviors were statistically significant in relation to antisocial behavior problems and depressed mood, both moderate and severe. Multiplicative effects of depressed mood and antisocial problems were found, with comorbid individuals showing increased risk of thoughts of death and suicidal plans and attempts, compared to individuals displaying none. Possible explanations, particularly for the multiplicative effect of both mood and problem behaviors on suicide-related behaviors, are discussed in the context of prior findings and directions for future research.
