Gender differences in the effects of childhood maltreatment on adult depression and anxiety: A systematic review and meta-analysis.

Child maltreatment has well-documented long-term, adverse effects on mental health, but it is not clear whether there are gender differences in these effects. We conducted a systematic review to investigate whether there are gender differences in the effects of maltreatment on adult depression and anxiety. Medline, PsycINFO, Web of Science, and Lilacs were searched for relevant studies published up to May 2016.

Childhood maltreatment preceding depressive disorder at age 18 years: A prospective Brazilian birth cohort study.

Background: Childhood maltreatment is linked with increased risk for mental illness in adolescence and adulthood. However, little evidence is available on whether different forms of maltreatment have specific effects, and no prospective studies in low- or middle-income countries have addressed this issue.

Methods: Participants in a population-based, birth cohort study in Pelotas, Brazil (N=3715) self-reported exposure to maltreatment (emotional abuse, physical neglect, physical abuse, sexual abuse, domestic violence) in confidential questionnaires at age 15 years, and were assessed for major depression in interviews at age 18 years, using the MINI.

Official data were obtained from the Secretariat for Public Security and the Special Court for Children and Youth. Victimization was registered for in 1,150 cohort members, with 1,396 incidents recorded as of December 31, 2012.

Childhood behaviour problems predict crime and violence in late adolescence: Brazilian and British birth cohort studies.

Purpose: Most children live in low- and middle-income countries (LMICs), many of which have high levels of violence. Research in high-income countries (HICs) shows that childhood behaviour problems are important precursors of crime and violence. Evidence is lacking on whether this is also true in LMICs.

Epidemiology of childhood conduct problems in Brazil: systematic review and meta-analysis.

[Size at birth and mental health problems at 11 years of age in a Brazilian birth cohort].

The aim of this study was to evaluate the association between size at birth and mental health problems at 11 years of age in the 1993 Pelotas (Brazil) Birth Cohort Study. Newborns were weighed and measured, and anthropometric indices were calculated. At 11 years of age, mental health problems were assessed using the Strengths and Difficulties Questionnaire (SDQ).
