OBJECTIVE: To report the rate of exposure to different violent events, their demographic correlates, the prevalence of Post-Traumatic Stress Disorder (PTSD), and the impact on quality of life. MATERIAL AND METHODS: The National Survey of Psychiatric Epidemiology is representative of the Mexican urban population aged 18 to 65. The survey was undertaken in 2001 and 2002 using the Composite International Diagnostic Interview (CIDI- 15) computerized version. The statistical analyses take into account the multistage, stratified, and weighted sample design. Kaplan-Meier and logistic regressions were performed. RESULTS: Sixty-eight percent of the population has been exposed to at least one stressful life event. Exposure varies by sex (rape, harassment, and sexual abuse are more frequent in women; accidents and being a victim of burglary among men) and by age (more frequent in children, adolescents, young adult women, and the elderly). By sex, 2.3% of women and 0.49% of men present PTSD. Rape, harassment, kidnapping, and sexual abuse are the events most associated with PTSD. CONCLUSIONS: The results suggest the need to increase treatment coverage to attend the consequences of violence, taking into consideration the important gender and age variations.
