Abstract
Background
Results of the relationships between diabetes and the risk of suicide death are inconclusive. This meta-analysis was conducted to assess this association.
Methods

6 observational studies (8 independent reports) with a total of 3,075,214 participants and 3038 suicide deaths events were included in the meta-analysis. Overall, diabetes was not associated with risk of suicide deaths, with significant heterogeneity among studies observed (Conclusion
Our meta-analysis based on more than 3 million participants indicates that diabetes is not associated with increased risk of suicide death. Further well-designed prospective cohort studies are needed to confirm the findings of this meta-analysis.
