Lifelong robbery victimisation and mental disorders at age 18 years: Brazilian population-based study

Early and Frequent Psychiatric Readmissions in a Brazilian Cohort of Hospitalized Patients Between 2001 and 2013

OBJECTIVE

To characterize the profile of patients who were readmitted for mental and behavioral disorders, in the Brazilian Unified Health System, from 2001 to 2014, and the factors associated with early and frequent readmission.

METHOD

A retrospective, non-concurrent cohort study of patients admitted with a primary diagnosis of mental or behavioral disorders, from 2001 to 2014. This study selected demographic variables and clinical variables, as well as variables related to the characteristics of the hospitals. Poisson Regression methods with a robust variance estimator were used to estimate the incidence rate ratio (IRR) for each of the outcomes.

RESULTS

Early readmission occurred for 6.8% of the patients and frequent readmission for 8.3%. Characteristics such as being male, younger, with a diagnosis of a bipolar disorder, and admitted to a specialized hospital show a higher IRR for early readmission. The occurrence of early readmission was the most heavily associated characteristic with an increased rate of early readmission, and the magnitude of this increase depends on the patient's age.

CONCLUSION

Early and frequent readmissions are linked to patients' demographics, clinical information and health system's organization. Early readmission should be a priority in treatment planning to prevent frequent readmissions due to its strong association.

Mental distress in relation to police reporting among adolescent victims of robbery. A population-based study in southern Sweden

•Robberies as well as mental distress have increased among adolescents in Sweden.•This study on school students in southern Sweden was population-based with a high response rate.•Half of the robbed adolescents abstained from police reporting.•Non-reporters had poorer mental health than victims who reported the robbery.•Non-reporters were also an overall more disadvantaged group.

Robbery Victimization in Early Adulthood, and Depression and Anxiety at Age 30 Years: Results From the 1982 Pelotas (Brazil) Birth Cohort Study

Robbery is one of the most common urban crimes, but little is known about its relationship with mental disorders in young adults. This study aimed to assess the relationship between robbery victimization and Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD) and comorbidity between MDD and GAD at 30 years of age. A birth cohort study has followed all children born in the city of Pelotas, southern Brazil, since 1982. At ages 23 and 30 years, participants were interviewed and asked about lifetime and recent experiences of robbery. Covariates were measured in interviews between birth and age 30 years. MDD and GAD were measured using the MINI-International Neuropsychiatric Interview. Adjusted prevalence ratio (aPR) and corresponding 95% confidence interval (CI) for associations between robbery and mental disorders were calculated using Poisson regression with robust standard error. Of 3,701 cohort members interviewed at age 30 years, 42% reported robbery victimization during their lifetime. Victimization across three periods (lifetime, past 10 years, past 12 months) was associated with increased occurrence of MDD, GAD, as well as the MDD and GAD comorbidity. The strongest associations were found to robbery occurring in the previous 12 months with the MDD and GAD comorbidity, both for burglary at home (aPR 2.52; 95% CI 1.52-4.22) or community family victimization (aPR 2.10; 95% CI 1.34-3.27). These findings highlight the importance of community violence for mental health in young adulthood, and the need for public policies to prevent violence as well as support services for victims to mitigate its adverse health consequences.

Imaging Social and Environmental Factors as Modulators of Brain Dysfunction: Time to Focus on Developing Non-Western Societies

Social and environmental factors are known risk factors and modulators of mental health disorders. We here conducted a nonsystematic review of the neuroimaging literature studying the effects of poverty, urbanicity, and community violence, highlighting the opportunities of studying non-Western developing societies such as those in Latin America. Social and environmental factors in these communities are widespread and have a large magnitude, as well as an unequal distribution, providing a good opportunity for their characterization. Studying the effect of poverty in these settings could help to explore the brain effect of economic improvements, disentangle the effect of absolute and relative poverty, and characterize the modulating impact of poverty on the underlying biology of mental health disorders. Exploring urbanicity effects in highly unequal cities could help identify the specific factors that modulate this effect as well as examine a possible dose-response effect by studying megacities. Studying brain changes in those living among violence, which is particularly high in places such as Latin America, could help to characterize the interplay between brain predisposition and exposure to violence. Furthermore, exploring the brain in an adverse environment should shed light on the mechanisms underlying resilience. We finally provide examples of two methodological approaches that could contribute to this field, namely a big cohort study in the developing world and a consortium-based meta-analytic approach, and argue about the potential translational value of this research on the development of effective social policies and successful personalized medicine in disadvantaged societies.
