The association of religiosity with suicidal ideation and suicide attempts in the United Kingdom.Objective: The goal was to analyze the association of religiosity with suicidal ideation and suicide attempts in a UK nationally representative sample.Methods: This study used cross-sectional data from 7403 people who participated in the 2007 Adult Psychiatric Morbidity Survey (APMS). Religion was assessed with the question 'Do you have a specific religion?' with 'yes' and 'no' answer options. Lifetime and past 12month suicidal ideation and suicide attempts were assessed. The association between religiosity and suicidality was studied in multivariable logistic regression models adjusted for sociodemographic, behavioural, and psychopathological factors. Results: Compared to those without a religion, the prevalence of past 12-month suicidal ideation (3.2% vs. 5.4%), past 12-month suicide attempts (0.4% vs. 0.9%), lifetime suicidal ideation (11.2% vs. 16.4%), and lifetime suicide attempts (3.6% vs. 6.0%) was lower among those with a religion. In the fully adjusted model, having a religion was significantly associated with lower odds for all types of suicidality except past 12-month suicide attempts: suicidal ideation (past 12month: OR = 0.71, 95% CI = 0.51-0.99; lifetime: OR = 0.83, 95% CI = 0.69-0.99) and suicide attempts (past 12-month: OR = 0.71, 95% CI = 0.35-1.45; lifetime: OR = 0.69, 95% CI = 0.53-0.90). Conclusion: There is a negative association between religiosity and suicidality in the UK. Future studies should focus on the underlying mechanisms.
Significant outcomes• The prevalence of suicidal ideation and suicide attempts was lower in religious people than in non-religious people in the UK.• There was a significant and negative relationship of religiosity with suicidal ideation (past 12-month and lifetime) and suicide attempts (lifetime) after adjustment for sociodemographic, behavioural, and psychopathological factors.• Future studies are needed to gain a better understanding of the underlying mechanisms involved in this association.
Limitations• More detailed series of questions on religiosity would have allowed for a better estimation of the religiosity-suicidality relationship.• Suicidality was assessed with self-reports. As suicide is associated with stigma, participants might have responded in a socially desirable manner, potentially leading to an underestimation of the associations.• The design of this study was cross-sectional, and it was thus not possible to determine causality or temporality in the association between religiosity and suicidal ideation or suicide attempt.
