Purposes: Mental health diseases (MHD) are responsible for 16% of the global burden of disease in adolescents. This review focus on one contextual factor nominated community violence (CV) that can contribute to the development of MHD. Objective: to evaluate the impact of CV on internalizing mental health symptoms (IMHS) in adolescents, to investigate whether different proximity to CV (witness x victim) is associated with different risks and to identify whether gender, age, and race moderate this association. Methods: systematic review of observational studies. Population includes adolescents (10 - 24 years), exposition involves individuals exposed to CV and outcomes consists of IMHS. Selection, extraction and quality assessment were performed independently by two research. Results: 2987 works were identified, after selection and extraction it remained 42. Higher exposure to CV were associated positively with IMHS. Being a witnessing is less harmful for mental health than being a victim. Age and race did not appear in the results as modifiers, but masculine gender and family support appear as a protective factor in some studies. Conclusion: This review confirms the positive relationship between CV and IMHS in adolescents and brings relevant information that can direct public efforts to build policies in prevention of both problems.

Resumo Conclusões O objetivo deste artigo é analisar a associação entre a cobertura de Centros de Atenção Psicossocial (CAPS) e a Atenção Básica (AB) e o número de internações psiquiátricas, nas regiões metropolitanas das capitais dos Estados de Rio de Janeiro (RJ) e São Paulo (SP). Estudo ecológico de séries temporais com população composta por residentes das regiões metropolitanas dos municípios do RJ e de SP internados no âmbito do SUS. Dados secundários foram coletados (portal do DATASUS e IBGE) e calculados indicadores (oferta de CAPS, cobertura da AB, oferta de leitos psiquiátricos e taxa de internações psiquiátricas). Foram calculadas as tendências temporais dos indicadores e a associação entre as coberturas de CAPS e AB e as taxas de internação. Observou-se redução das taxas de internações psiquiátricas e oferta de leitos e aumento da cobertura de CAPS e AB nas duas localidades estudadas, com associação inversa e estatisticamente significativa. : os resultados confirmaram a hipótese de associação entre as tendências crescentes de oferta de CAPS e AB e diminuição das taxas de internação psiquiátrica no período e regiões do estudo. Este achado reforça a importância da continuidade e aprimoramento das políticas relacionadas às reformas psiquiátrica e sanitária. Abstract To analyze the association between the coverage of psychosocial care centers (CAPS) and Primary Health Care (PHC) and the number of psychiatric hospitalizations in the metropolitan regions of the capitals of Rio de Janeiro (RJ) and São Paulo (SP) states. This is an ecological time-series study with population consisting of dwellers of metropolitan areas of the municipalities of RJ and SP hospitalized in the Unified Health System (SUS). Secondary data were collected from DATASUS and IBGE portal and indicators calculated (CAPS supply, PHC coverage, provision of psychiatric beds and psychiatric hospitalization rates). Indicators’ time trends and the association between CAPS and PHC coverage and hospitalization rates were calculated. Reduced psychiatric hospitalizations rates and psychiatric beds and increased CAPS and PHC coverage were observed in the two location under study, with inverse and statistically significant association. Results confirmed the hypothesis of association between increasing CAPS and PHC supply with decreased psychiatric hospitalization rates, in the study’s period and regions. This finding reinforces the importance of continuous and improved health and psychiatric reform-related policies.

Background: Mental health diseases are responsible for 16% of the global burden of disease in adolescents. Identifying the main determinants of these disorders in this age group can direct public and political efforts aimed at their prevention. Two previous meta-analyses showed a moderate and positive effect between exposure to community violence and mental health symptoms; however, there are still significant gaps to be addressed. Objectives: To evaluate whether adolescents’ exposure to a higher degree of community violence is associated with a higher risk of internalizing mental health symptoms and to investigate whether degrees of community violence events (victimization, witnesses and heard about) is associated with a higher risk of internalizing mental health outcomes (depression, anxiety and postraumatic stress disorder). Methods: A systematic review, research question and inclusion and exclusion criteria were developed according to the PEO format. The population consists of adolescents aged 10 to 24 years, the exposition involves individuals who were exposed to community violence, the comparison is adolescents who were not exposed or who were exposed to community violence to a smaller degree, and the outcome consists of internalizing mental health symptoms. Selection, extraction and quality assessment are being performed independently by two researchers. Results: A narrative synthesis will be presented. If possible, a meta-analysis will be performed with subgroup analyses of age, sex, degree of community violence and race. Publication bias will be assessed using funnel plots. This protocol has been registered in the International Prospective Register of Systematic Reviews (PROSPERO) - CRD 42019124740.
