Objectives: Children of depressed mothers are at risk of developing mental health problems. We sought to determine whether treatment for maternal depression by community-based health workers would decrease behavioral/emotional symptoms in their children. Interventions for maternal depressive symptoms in a low/middle-income country can have a high global impact. Methods: Community-based health workers were trained to deliver a psychosocial intervention for mothers with depression in a primary care setting. A total of 49 mothers and 60 children were assessed pre-intervention, post-intervention, and at 6 months follow-up. Child behavioral/emotional symptoms were evaluated according to type of change in maternal depressive symptoms: response or remission. Results: An overall decrease in maternal depressive symptoms from baseline to post-intervention and 6 months follow-up were found. Response or remission was associated with better outcomes in child behavioral/emotional symptoms at 6 months follow-up (p = 0.0247, Cohen’s d: 0.76; p = 0.0224, Cohen’s f: 0.44) but not at post-intervention (p = 0.1636, Cohen’s d: 0.48; p = 0.0720, Cohen’s f: 0.33). Conclusions: Improvement in maternal depression was related to decreased behavioral/emotional symptoms in their children. Our results suggest that providing interventions for maternal depression in primary care is a viable strategy to prevent behavioral/emotional symptoms in the next generation.

Objective: Much research has been published on the role of sexual revictimization in the emergence of mental disorders in adulthood, but findings have sometimes been contradictory. The present systematic review sought to assess the state of the evidence on revictimization as a potential factor for the emergence of posttraumatic stress disorder (PTSD). Methods: Electronic searches were conducted in five databases (MEDLINE/PubMed, Cochrane Library, Campbell Library, PsycINFO, and LILACS), using the terms PTSD, posttraumatic stress disorder, child abuse, and rape. Results: We identified nine articles that established a connection among childhood sexual abuse (CSA), sexual revictimization in adulthood, and development of PTSD. Eight of the nine papers included were classified as having strong methodological quality (grade VI). One was classified as IV, with an average quality-of-evidence rating. The mean methodological quality score of the articles was 5.5, and the quality of evidence was deemed strong. Conclusion: In the included studies, PTSD symptoms were most prevalent in the CSA + adult sexual assault groups, providing further evidence for the revictimization hypothesis.

Objective: To ascertain whether genetic variations in the serotonin transporter gene (5-HTTLPR 44-bp insertion/deletion polymorphism) influence an increase in depressive and anxiety symptoms in children and adolescents exposed to high levels of violence. Methods: Saliva samples were collected from a group of children who were working on the streets and from their siblings who did not work on the streets. DNA was extracted from the saliva samples and analyzed for 5-HTTLPR polymorphism genotypes. Results: One hundred and seventy-seven children between the ages of 7 and 14 years were analyzed (114 child workers and 63 siblings). Data on socioeconomic conditions, mental symptoms, and presence and severity of maltreatment and urban violence were collected using a sociodemographic inventory and clinical instruments. There was no positive correlation between the 5-HTTLPR polymorphism and presence of mental symptoms in our sample, although the children were exposed to high levels of abuse, neglect, and urban violence. Conclusions: Despite previous studies that associated adult psychiatric disorders with the 5-HTTLPR polymorphism and a history of childhood maltreatment, no such association was found in this sample of children at risk.

Objective: To quantitatively study the exposure to childhood maltreatment and urban violence in children from families with at least one child working on the streets and to investigate the relationship between these factors and street work. Methods: Families who participated in a nongovernmental organization (NGO) program to eliminate child labor were included. Data concerning sociodemographic characteristics, punishment methods used in the family environment against the children, five types of abuse and neglect perpetrated by the caregivers, urban violence exposure and family functioning were collected. Results: The sample included 126 children who were working on the streets and 65 siblings who were not working on the streets. Caregivers reported high levels of severe physical punishment. The children reported high levels of abuse and neglect, and high levels of urban violence exposure. The families showed a predominance of dysfunctional and unsatisfactory relationships. A multiple logistic regression model showed that age older than 12 years and severe physical punishment at home were associated with street work. Conclusion: Interventions to decrease the risk of child street work should be family-focused and should aim to reduce violence in the family environment.

OBJETIVO: A meta deste artigo foi a de estudar as relações ente maus-tratos na infância e psicopatologia no adulto, como reflexo de uma disfunção do eixo hipotálamo-pituitária-adrenal. MÉTODO: Uma revisão seletiva da literatura relevante foi feita para identificar achados-chave e ilustrativos. RESULTADOS: Existe atualmente um volume significativo de achados científicos pré-clínicos e clínicos derivados de paradigmas experimentais, que demonstram que o estresse precoce está relacionado à função do eixo hipotálamo-pituitária-adrenal e a estados psicológicos no indivíduo adulto, e como esta relação pode ser modulada por outros fatores. DISCUSSÃO: O risco para o desenvolvimento de psicopatologia no adulto e disfunções do eixo hipotálamo-pituitária-adrenal está relacionado à complexa interação de múltiplos fatores vivenciais, assim como a genes que levam a uma susceptibilidade, que interagem com estes fatores. Embora as respostas agudas do eixo hipotálamo-pituitária-adrenal sejam geralmente adaptativas, as respostas excessivas podem levar a efeitos deletérios. O estresse precoce pode alterar a função do eixo hipotálamo-pituitária-adrenal assim como o comportamento, porém, o padrão da disfunção do eixo hipotálamo-pituitária-adrenal e a evolução psicológica na vida adulta refletem ambas as características do estressor e outros fatores modificadores. CONCLUSÃO: A pesquisa atual identificou múltiplos determinantes da disfunção do eixo hipotálamo-pituitária-adrenal encontrados em adultos com história de maus-tratos na infância ou outros estressores precoces. Trabalhos futuros são necessários para estabelecer se as anormalidades do eixo hipotálamo-pituitária-adrenal neste contexto podem ser usadas para o desenvolvimento de endofenótipos de risco para doenças físicas ou psiquiátricas.

OBJECTIVE: The aim of this paper was to examine the relationship between childhood maltreatment and adult psychopathology, as reflected in hypothalamic-pituitary-adrenal axis dysfunction. METHOD: A selective review of the relevant literature was undertaken in order to identify key and illustrative research findings. RESULTS: There is now a substantial body of preclinical and clinical evidence derived from a variety of experimental paradigms showing how early-life stress is related to hypothalamic-pituitary-adrenal axis function and psychological state in adulthood, and how that relationship can be modulated by other factors. DISCUSSION: The risk for adult psychopathology and hypothalamic-pituitary-adrenal axis dysfunction is related to a complex interaction among multiple experiential factors, as well as to susceptibility genes that interact with those factors. Although acute hypothalamic-pituitary-adrenal axis responses to stress are generally adaptive, excessive responses can lead to deleterious effects. Early-life stress alters hypothalamic-pituitary-adrenal axis function and behavior, but the pattern of hypothalamic-pituitary-adrenal dysfunction and psychological outcome in adulthood reflect both the characteristics of the stressor and other modifying factors. CONCLUSION: Research to date has identified multiple determinants of the hypothalamic-pituitary-adrenal axis dysfunction seen in adults with a history of childhood maltreatment or other early-life stress. Further work is needed to establish whether hypothalamic-pituitary-adrenal axis abnormalities in this context can be used to develop risk endophenotypes for psychiatric and physical illnesses.
