Longitudinal associations between adolescents' individualised risk for depression and inflammation in a UK cohort study.

Inflammation is associated with poor physical and mental health including major depressive disorder (MDD). Moreover, there is evidence that childhood adversity - a risk factor for MDD - becomes biologically embedded via elevated inflammation. However, the risk of developing MDD arises from multiple sources and yet there has been little investigation of the links between individuals' constellation of MDD risk and subsequent inflammation.

Childhood exposure to ambient air pollution and predicting individual risk of depression onset in UK adolescents.

Knowledge about early risk factors for major depressive disorder (MDD) is critical to identify those who are at high risk. A multivariable model to predict adolescents' individual risk of future MDD has recently been developed however its performance in a UK sample was far from perfect. Given the potential role of air pollution in the aetiology of depression, we investigate whether including childhood exposure to air pollution as an additional predictor in the risk prediction model improves the identification of UK adolescents who are at greatest risk for developing MDD.

Predicting the risk of future depression among school-attending adolescents in Nigeria using a model developed in Brazil.

Depression commonly emerges in adolescence and is a major public health issue in low- and middle-income countries where 90% of the world's adolescents live. Thus efforts to prevent depression onset are crucial in countries like Nigeria, where two-thirds of the population are aged under 24. Therefore, we tested the ability of a prediction model developed in Brazil to predict future depression in a Nigerian adolescent sample.

Predicting the risk of depression among adolescents in Nepal using a model developed in Brazil: the IDEA Project.

The burden of adolescent depression is high in low- and middle-income countries (LMICs), yet research into prevention is lacking. Development and validation of models to predict individualized risk of depression among adolescents in LMICs is rare but crucial to ensure appropriate targeting of preventive interventions. We assessed the ability of a model developed in Brazil, a middle-income country, to predict depression in an existing culturally different adolescent cohort from Nepal, a low-income country with a large youth population with high rates of depression.

Identifying Adolescents at Risk for Depression: A Prediction Score Performance in Cohorts Based in 3 Different Continents.

Objective: Prediction models have become frequent in the medical literature, but most published studies are conducted in a single setting. Heterogeneity between development and validation samples has been posited as a major obstacle for the generalization of models. We aimed to develop a multivariable prognostic model using sociodemographic variables easily obtainable from adolescents at age 15 to predict a depressive disorder diagnosis at age 18 and to evaluate its generalizability in 2 samples from diverse socioeconomic and cultural settings.

Translation and cross-cultural adaptation into Brazilian Portuguese of the Mood and Feelings Questionnaire (MFQ) - Long Version.

Introduction Major depressive disorder (MDD) is prevalent among young people, with a high incidence during adolescence. It is, therefore, important to have reliable instruments to capture the construct of depression in this population. The objective of the present work is to describe the process of translation and cultural adaptation of the Mood and Feelings Questionnaire (MFQ) - Long Version, into Brazilian Portuguese.

Attention-Deficit/Hyperactivity Disorder Trajectories From Childhood to Young Adulthood: Evidence From a Birth Cohort Supporting a Late-Onset Syndrome.

Importance: The requirement of a childhood onset has always been a key criterion for the diagnosis of attention-deficit/hyperactivity disorder (ADHD) in adults, but recently this requirement has become surrounded by controversy.

Objective: To investigate whether impaired young adults with ADHD symptoms always have a childhood-onset disorder in a population-based longitudinal study.

Design, Setting, And Participants: Participants belonged to the 1993 Pelotas Birth Cohort Study, including 5249 individuals born in Pelotas, Brazil, in 1993.

Gene-Environment Interaction in Youth Depression: Replication of the 5-HTTLPR Moderation in a Diverse Setting.

Objective: Replication of scientific findings is a major challenge in biomedical research. In psychiatry, the identification of measured gene-environment interactions (G×E) has promoted a heated debate over the past decade, with controversial results about its influence on disorders such as major depression. The authors sought to replicate a 2003 study on G×E in youth depression in a large birth cohort from a diverse setting.

Provision of mental healthcare for children and adolescents: a worldwide view.

Purpose Of Review: There has been increased attention towards the burden imposed by mental disorders on children and adolescents. The present overview explores the current state of child and adolescent mental healthcare provision around the globe.

Recent Findings: Current research indicates a concerning gap in the provision of care for the child and adolescent population.

Mood disorders in childhood and adolescence.

The identification and treatment of mood disorders in children and adolescents has grown over the last decades. Major depression is one of the most common and debilitating disorders worldwide, imposing a massive burden to the youth population. Bipolar disorder is being increasingly recognized as having its roots early in life, and its presentation during childhood and adolescence has been submitted to extensive research.

Age of Sexual Initiation, Psychiatric Symptoms, and Sexual Risk Behavior among Ecstasy and LSD Users in Porto Alegre, Brazil: A Preliminary Analysis.

Ecstasy and LSD use is widespread in large Brazilian cities, but there is limited information on their use among young, middle-class, club goers in Brazil. We conducted standardized face-to-face interviews with 200 male and female ecstasy and/or LSD users, focusing on drug use and sexual history, current risk behaviors, and psychiatric symptomatology. Participants with early sexual debut (before 14) were more likely to report lifetime use of marijuana and powder and crack cocaine than those with later sexual initiation.
