ABSTRACT
OBJECTIVES: To further our understanding of the relationship between Adverse Childhood Experiences (ACEs) and suicidal behaviour, this study investigates the association between three types of ACEs and lifetime suicide attempts, while considering potential gender-specific and mediating effects. METHODS: Data were obtained from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH), a cross-sectional, population-based survey comprised of respondents aged 18 or older who provided self-reported data on past experiences of suicide attempts, as well as childhood sexual abuse (CSA), childhood physical abuse (CPA) and parental domestic violence (PDV) (n = 22 559). After testing for ACE by gender interactions, we estimated the odds of lifetime suicide attempts for each ACE and then investigated whether depression, anxiety, substance abuse and chronic pain acted as mediators of the relationship. RESULTS: The odds of suicide attempts are significantly higher among those with a history of CPA (OR = 3.29; 99.9% CI 2.33-4.64), CSA (OR = 4.42; 99.9% CI 3.14-6.23) or PDV (OR = 2.52; 99.9% CI 1.69-3.76), when ACEs are mutually adjusted. There is little evidence that gender acts as a moderator; however, depression, anxiety, substance abuse and chronic pain appear to partially mediate the associations. Depression alone accounts for about a quarter of the associations with CSA and CPA. CONCLUSIONS: Mental health factors and chronic pain appear only to partially mediate relationships between ACEs and lifetime suicide attempts. Future research should look at other pathways with the goal of developing multi-level interventions.

Several studies have examined the association between childhood physical abuse (CPA) and anxiety disorders with inconsistent results. In order to help clarify this relationship, we investigated the association between CPA and current anxiety disorders while controlling for the following groups of factors: (1) demographics; (2) family background; (3) current socioeconomic status (SES); (4) current stressors; and (5) current mood disorders. Data from the 2005 Canadian Community Health Survey were analyzed. The sample included 12,481 respondents from the Canadian provinces of Manitoba and Saskatchewan. The regional-level response rate was 84%. Fully 7.3% (n = 964) of respondents reported they had been physically abused as a child or adolescent by someone close to them and 4.4% (n = 540) reported they had been diagnosed with an anxiety disorder by a health professional. A significant association between CPA and anxiety disorders was found when controlling for demographic factors, family background, current SES and stressors (OR = 1.61; 95% CI = 1.25, 2.08). The odds of anxiety disorders declined to non-significance when further statistical adjustments were made for current mood disorders. The findings of this research suggest that the relationship between CPA and anxiety may be largely explained by co-morbid mood disorders.
