BACKGROUND: The mental health consequences of exposure to childhood trauma have been little studied among adolescents in low-income and-middle-income countries (LMICs), despite a relatively high burden of trauma in LMIC populations. We investigated associations between trauma and adolescent psychiatric disorders in the 2004 Pelotas Birth Cohort, Brazil. METHODS: In the 2004 Pelotas Birth Cohort, current psychiatric diagnoses (anxiety, mood, attention-hyperactivity, and conduct-oppositional disorders) were assessed at age 15 years (caregiver-report Development and Well-being Assessment), and age 18 years (self-report Mini-International Neuropsychiatric Interview). Lifetime cumulative trauma was assessed via caregiver report up to age 11 years and combined self-report and caregiver-report thereafter. Exposure to 12 trauma types were assessed (serious accident, fire, other disaster, attack or threat, physical abuse, sexual abuse, witnessed domestic violence, witnessed attack, witnessed accident, heard about attack, heard about accident, and parental death). Due to the high prevalence of trauma exposure in the sample, the number of different types of trauma exposure reported was extracted as a proxy for cumulative trauma load. We assessed both cross-sectional and longitudinal associations between cumulative trauma load and psychiatric disorders during adolescence using logistic regression, adjusting for confounders and pre-existing child psychopathology at 48 months. We also comp...
