OROZCO, Ricardo et al. Traumatic life events and posttraumatic stress disorder among Mexican adolescents: results from a survey. Salud pública Méx [online]. 2008, vol.50, suppl.1, pp.s29-s37. ISSN 0036-3634.

OBJECTIVE: To estimate the prevalence and the association of Traumatic Life Events (LEs) and Posttraumatic Stress Disorder (PTSD) among the Mexico City Metropolitan Area (MCMA) adolescent population. MATERIAL AND METHODS: Adolescents aged 12 to 17 were administered the adolescent version of the World Mental Health Composite International Diagnostic Interview (n=3 005). Data were collected using a stratified, multistage and probability sample. Prevalence, odds ratios and 95% confidence intervals for LEs and PTSD (assessed with DSM-IV criteria) were obtained. RESULTS: The percentage of adolescents reporting at least one traumatic event in their lifetimes was 68.9%, with differences by sex. Prevalence for PTSD were 1.8% (2.4% females and 1.2% males), and sexual-related traumas were the LEs most associated with PTSD [OR=3.9 (CI95%=1.8-8.2)], adjusted by sex, education and age. CONCLUSIONS: Exposure to traumatic life events is not uncommon among Mexico City adolescents. Effort should be made to reduce child and adolescent sexual abuse, a very traumatic event highly associated with PTSD.
