Objective: childhood sexual abuse (CSA) is an important mental health issue with pervasive and sustaining impact. Method: we did a comprehensive review over 29 recently-published literatures. Results: increased suicidal risk has been reported among CSA individuals and there exists a graded relationship between the CSA severity and suicidal risk. This relationship is independent of the confounding effect of other coexisting childhood adversities. Possible mediators, which facilitate the development of suicidal behavior, may include psychopathology and stressful life events. Conclusion: early recognition of CSA and prompt management of related psychosocial difficulties may help reduce subsequent suicidal risk in this specific population.
