We estimated the costs to the public purse of health, education, criminal justice and social care service use associated with psychiatric conditions among adolescents in Brazil; and examined whether the trajectory of psychopathology and its impact on daily life, and parental stigma towards mental illness, was associated with service utilisation and costs. Methods Data on reported service use among adolescents from a prospective community cohort (n = 1,400) were combined with Brazilian unit costs. Logistic regression and generalised linear models were used to examine factors associated with service use and associated costs, respectively. Results Twenty-two percent of those who presented with a psychiatric disorder used some type of service for their mental health in the previous twelve months. Higher odds of ...

The extent to which multiple modifiable risk factors among children and families influence juvenile criminal conviction in an LMIC remains unexplored; however, it is necessary to identify prevention targets. This study examined the association between 22 modifiable individual and family exposures assessed in childhood (5–14 years, n = 2511) and criminal conviction at a 7-year follow-up (13–21 years, n = 1905, 76% retention rate) in a cohort of young people in Brazil. Population attributable risk fraction (PARF) was computed for significant risk factors. Criminal convictions were reported for 81 (4.3%) youths. Although most children living in poverty did not present criminal conviction (89%), poverty at baseline was the only modifiable risk factor significantly associated with crime (OR 4.14, 99.8% CI 1.38–12.46) with a PARF of 22.5% (95% CI 5.9–36.1...

In Mozambique, there have been numerous reports of ECB in recent years. Since 2010 several girls from a secondary school in Maputo City, Mozambique exhibited ECB which involved repeated fainting spells, sometimes including verbal aggression and threats to colleagues and teachers. We conducted a study to analyze sociodemographic and clinical characteristics associated with ECB. Methods: This cross-sectional study included 154 females aged from 16 to 24 years old. We considered emotional contagion behavior as repeated fainting spells, sometimes including verbal aggression and threats to others (colleagues and teachers). Participants responded to a sociodemographic questionnaire, the Beck Anxiety Scale, and the revised Eysenck Personality Questionnaire (EPQ-R). Bivariate and multivariate logistic regression models analyzed sociodemograp...

Caregiver characteristics/experiences/beliefs may influence whether young people get help and the type of care or support used by their child. We investigate facilitators/barriers to receiving formal and/or informal care, particularly those related to the caregiver’s profile.MethodsWe interviewed 1,400 Brazilian primary caregivers of young people (aged 10–19), participants of a high-risk cohort. Caregivers reported on young people’s formal/informal mental health care utilization, and associated barriers and facilitators to care. Data were also collected on youth mental health and its impact on everyday life; and caregiver characteristics—education, socioeconomics, ethnicity, mental health, and stigma. Logistic regression models were used to examine the relationship between caregiver and young people characteristics with formal/informal care utilization.ResultsPersistence and gr...

We also investigated whether the association between poverty in childhood and MHD is mediated by exposure to stressful life events (SLE). We used data from a prospective community cohort of young people assessed at baseline (M = 9.7 years, SD = 1.9), first (M = 13.5 years, SD = 1.9), and second (M = 18.2 years, SD = 2.0) follow-ups (N = 1,590) in Brazil. Poverty was assessed using a standardized classification. Exposure to 20 different SLE was measured using the Life History instrument. Psychiatric diagnoses were evaluated using the Development and Well-Being Assessment. Latent growth models investigated the association between poverty at baseline and the growth of any MHD, externalizing, and internalizing disorders. Mediation models evaluated whether the association between childhood poverty and MHD in early adulthood was mediated by exposure to SLE. Poverty affected 11.4% of the sample at baseline and was associated with an increased propensity for presenting externalizing disorders in adolescence or early adulthood (standardized estimate = 0.27, p = 0.016). This association was not significant for any disorder or internalizing disorders. Childhood poverty increased the likelihood of externalizing disorders in early adulthood through higher exposure to SLE (OR = 1.07, 95 CI% 1.01–1.14). Results were only replicated among females in stratified analyses. Childhood poverty had detrimental consequences on externalizing MHD in adolescence, especially among females. Poverty and SLE are preventable risk factors that need to be tackled to reduce the burden of externalizing disorders in young people.

We examined whether exposure to Brazil's conditional cash transfers programme (CCT), Bolsa Família (BFP), during childhood reduces the risk of mental health problems in early adolescence. Methods We used data from 2063 participants in the 2004 Pelotas Birth Cohort study. Propensity score matching (PSM) estimated the association between BFP participation at age 6 and externalising problems (Strengths and Difficulties Questionnaire-SDQ and violent behaviour) and socio-emotional competencies (Development and Well-Being Assessment questionnaire, and the Nowick-Strickland Internal-External Scale) at age 11. Results PSM results suggest that programme participation at age of six was not significantly associated with externalising problems (P = 0.433), prosocial behaviour (P = 0.654), violent behaviour (P = 0.342), social aptitudes (P = 0.281), positive attributes (P = 0.439), or locus of control (P = 0.148) at the age of 11 years. Conclusions Participation in BFP during childhood was not associated with improved or worsened mental health in early adolescence. While we cannot fully discard that findings may be due to adverse selection, results suggest that CCTs alone may not be sufficient to improve mental health outcomes and would be prudent to assess whether mental health interventions as an addition to CCTs may be helpful.

Our aims were to: (i) estimate the impacts of different types of psychiatric conditions on educational outcomes and (ii) to estimate the proportion of adverse educational outcomes which can be attributed to psychiatric conditions. Methods Participants (N = 2511) were from a school-based community cohort of Brazilian children and adolescents aged 6–14 years enriched for high family risk of psychiatric conditions. We examined the impact of fear- (panic, separation and social anxiety disorder, specific phobia, agoraphobia and anxiety conditions not otherwise specified), distress- (generalised anxiety disorder, major depressive disorder and depressive disorder not otherwise specified, bipolar, obsessive-compulsive, tic, eating and post-traumatic stress disorder) and externalising-related conditions (attention ...

In particular, cash transfer programmes are currently being adapted or expanded in various low-income and middle-income countries to support individuals and families during the pandemic. We argue that the current crisis offers an opportunity for these programmes to focus on susceptible young people (aged 15-24 years), including those with mental health conditions. Young people living in poverty and with mental health problems are at particular risk of experiencing adverse health, wellbeing, and employment outcomes with long-term consequences. They are also at risk of developing mental health conditions during this pandemic. To support this population, cash transfer programmes should not only address urgent needs around food security and survival but expand their focus to address longer-term mental health impacts of pandemics and economic crises. Such an approach could help support young people's future life chances and break the vicious cycle between mental illness and poverty that spirals many young people into both socioeconomic and mental health disadvantage.

Methods: A prospective cohort study with 358 low-income postpartum women with antenatal depression. All participants were enrolled in a cluster-randomized trial to evaluate the impact of a depression management program. The Postpartum Bonding Questionnaire and the Patient Health Questionnaire were used at 6–8 months postpartum to assess mother-infant bonding impairment (BI) and postpartum depression (PPD). The Denver Developmental Screening Test was used at 12–15 months after delivery to assess the child's neurodevelopment. Crude and adjusted odds ratios (ORs) were estimated using logistic regression. Results: Among 216 participants who received the CDD evaluation at 12–15 months, 158 (73.1%) had no symptoms of PPD or BI, while 11 (5.1%) had PPD and BI at the same time. CDD was observed in 15.3% (95% CI 10.4:20.1). CDD was associated with BI (OR:1.07; 95% CI 1.02:1.13), non-White skin color (OR: 3.40; 95% CI 1.10:10.39), masculine gender of the baby (OR: 4.71; 95% CI 1.66:13.37), and premature delivery or low birth weight (OR: 4.99; 95% CI 1.74:14.29). Conclusions: BI, but not PPD, at 6–8 months, is associated with CDD at 12–15 months. The assessment of BI, a modifiable risk factor for child development, should be included as part of proper maternal mental health care.

Our study sought to describe the most commonly used methods of suicide among adolescents aged 10 to 19 years in Brazil between 2006 and 2015. Complete data were obtained from the Brazilian Health Informatics Department (DATASUS) and coded into seven categories of suicide methods. The following statistical analyzes were performed: chi-square (χ 2) tests to examine the association between the frequency of each suicide method and the year; odds ratios (OR) and 95% confidence intervals (95%CI) compared the relative chances of each suicide method occurring between boys and girls. In total, 8,026 suicides among Brazilian adolescents were registered over the analyzed period. The most commonly used method of suicide by both sexes was hang

We report a systematic review of automated speech evaluation for the psychosis spectrum and analyze the value of information for a screening program in a healthcare system with a limited number of psychiatrists (Maputo, Mozambique). Methods: Original studies on speech analysis for forecasting of conversion in individuals at clinical high risk (CHR) for psychosis, diagnosis of manifested psychotic disorder, and first-episode psychosis (FEP) were included in this review. Studies addressing non-verbal components of speech (e.g., pitch, tone) were excluded. Results: Of 168 works identified, 28 original studies were included. Valuable speech features included direct measures (e.g., relative word counting) and mathematical embeddings (e.g.: word-to-vector, graphs). Accuracy estimates reported for schizophrenia diagnosis and CHR conversion ranged from 71 to 100% across studies. Studies used structured interviews, directed tasks, or prompted free speech. Directed-task protocols were faster while seemingly maintaining performance. The expected value of perfect information is USD 9.34 million. Imperfect tests would nevertheless yield high value. Conclusion: Accuracy for screening and diagnosis was high. Larger studies are needed to enhance precision of classificatory estimates. Automated analysis presents itself as a feasible, low-cost method which should be especially useful for regions in which the physician pool is insufficient to meet demand.
