Risk factors for suicidal tendency in adult patients with epilepsy in China

Abstract

ObjectiveThe major cause of premature mortality in people with epilepsy (PWE) is suicide. Actual data on the risk of suicidal tendency in adult PWE in China are scarce. In our study, associations between possible risk factors and suicidal tendency in adult PWE in China were investigated. MethodsPeople with epilepsy (n = 251) were recruited, and their demographic and clinical characteristics were evaluated. Suicide risk was examined using the suicidality module (SM) of the Mini International Neuropsychiatric Interview (MINI) Plus Chinese Version 5.0.0. ResultsSuicidal tendency was present in 36 (14.3%) of the 251 PWE. On the basis of the results of univariate analyses, family relationship (P < 0.001), age at epilepsy onset (P = 0.037), seizure-free period (P = 0.041), seizures/month (P = 0.015), depressive disorders (P < 0.001), and number of antiepileptic drugs (AEDs) (P = 0.017) were associated with suicidal tendency. Multivariate analysis revealed that moderate or poor family relationships (odds ratio (OR): 6.468, 95% confidence interval (CI): 2.418–17.300) and depressive disorders (OR: 3.548, 95% CI: 1.575–7.995) were associated with high odds of suicidal tendency. ConclusionSuicidal tendency is common among adult PWE. This study reveals that family relationships and depressive disorders are independent risk factors for suicidal tendency among adult PWE. Therefore, while maintaining treatment of epilepsy, more attention should be directed to the social support and mental state of PWE to prevent suicide.
