Background:
Whether multiple sclerosis is associated with a higher rate of suicide remains controversial. Therefore, we aimed to evaluate the risk of suicide in multiple sclerosis patients based on meta-analysis of previously published data.
Methods:
We searched for studies that measured the suicide risk in multiple sclerosis patients compared with general population that were published up to 1 December 2018 in PubMed, EMBASE, and Web of Science databases. Sixteen studies fulfilled the eligibility criteria. We performed random-effects meta-analyses to calculate suicide rate ratio (SRR) and 95% confidence intervals (CIs) for patients with multiple sclerosis.
Results:
The association between suicide and multiple sclerosis was statistically significant with a pooled SRR 1.72 (95%CI 1.48-1.99, I-squared = 55.0%). Risk of suicide at diagnosis of multiple sclerosis (SRR 2.12, 95% CI 1.84-2.46; I-squared = 4.4%) was higher than the risk of suicide at symptom onset (SRR 1.69; 95% CI 1.43-2.00; I-squared = 0.0%). Gender may exert an influence on the impact of sex on the association between MS multiple sclerosis and suicide, but this requires is controversial and need more further studies to demonstrate.
Conclusion:
Our meta-analysis shows a significant association between suicide and multiple sclerosis, although ethnic and geographical differences were not considered. These findings should be confirmed and extended in future large studies.
