Suicidal ideation among individuals whose parents have divorced: findings from a representative Canadian community...

This study used a large, nationally representative sample to examine the gender-specific association between parental divorce and the cumulative lifetime incidence of suicidal ideation. Known risk factors for suicidal ideation, such as childhood stressors, socioeconomic factors, adult health behaviors and stressors, marital status, and any history of mood and/or anxiety disorders were controlled. Gender-specific analyses revealed that for men, the parental divorce-suicidal ideation relationship remained statistically significant even when the above-listed cluster of risk factors were included in the analyses (odds ratio (OR)=2.36, 95% confidence interval (CI)=1.56, 3.58). For women, the association between parental divorce and suicidal ideation was reduced to non-significance when other adverse childhood experiences were included in the analyses (full adjustment OR=1.04, 95% CI=0.72, 1.50). These findings indicate a need for screening of suicidal ideation among individuals, particularly men and those with mood and/or anxiety disorders, who have experienced parental divorce. Future research should focus on the mechanisms linking parental divorce and suicidal ideation.
