Spirituality, religion and suicidal behavior in a nationally representative sample

BackgroundStudies show that religion and spirituality are associated with decreased rates of mental illness. Some studies show decreased rates of suicide in religious populations, but the association between religion, spirituality and suicidal behaviors in people with mental illness are understudied. Few studies have examined the influence of social supports in these relationships.MethodsData were drawn from the Canadian Community Health Survey 1.2. Logistic regression was used to examine the relationship between spiritual values and religious worship attendance with twelve-month suicidal ideation and attempts. Regressions were adjusted for sociodemographic factors and social supports. Interaction variables were then tested to examine possible effect modification by presence of a mental disorder.ResultsIdentifying oneself as spiritual was associated with decreased odds of suicide attempt (adjusted odds ratio-1 [AOR-1] = 0.65, CI: 0.44–0.96) but was not significant after adjusting for social supports. Religious attendance was associated with decreased odds of suicidal ideation (AOR-1 = 0.64, 95% CI: 0.53–0.77) but not after adjusting for social supports. Religious attendance was associated with decreased odds of suicide attempt and remained significant after adjusting for social supports (AOR-2 = 0.38, 95% CI: 0.17–0.89). No significant interaction effects were observed between any of the tested mental disorders and religion, spirituality and suicidal behavior.LimitationsThis was a cross-sectional survey and causality of relationships cannot be inferred.ConclusionsResults suggest that religious attendance is associated with decreased suicide attempts in the general population and in those with a mental illness independent of the effects of social supports.
