Abstract Introduction Most children/adolescents with disability live in low and middle-income countries and, worldwide, they are more likely to have mental health problems and achieve worse academic performance compared to those with typical development. Objective To assess whether Brazilian children/adolescents with four types of disabilities are more likely to have psychiatric disorders and educational deficits than children/adolescents with typical development. Method A multicenter cross-sectional study involving a school-based probabilistic sample of second to sixth graders (N = 1,674) from public schools in four Brazilian regions. The four types of disabilities (intellectual, visual, hearing, and motor) were assessed using the Ten Questions Questionnaire. Psychiatric disorders were measured with the Schedule for Affective Disorders/Schizophrenia for School-Age Children (K-SADS-PL), and academic performance was evaluated using the Teste de Desempenho Acadêmico – TDE (the academic performance test). Results A logistic regression model with cluster-robust errors identified the following statistically significant associations with three of the four types of disability (the exception was hearing). Intellectual disability was associated with anxiety (p < 0.01), depression (p < 0.01), attention deficit hyperactivity disorder (ADHD) (p < 0.001), school failure (p < 0.01), and poor academic performance (p < 0.01). Visual disability was associated with depression (p < 0.01). Motor disability was marginally associated with ADHD (p = 0.08). Conclusions Presence of disabilities (intellectual, visual, and motor) in children/adolescents was associated with psychiatric disorders, school failure, and academic performance. It is therefore important to identify presence of disabilities and plan and deliver specific interventions and specialized educational care for the needs presented by these children/adolescents. This is particularly important in low and middle-income countries, where these disabilities are frequent among children/adolescents.

RESUMOOs Transtornos do Espectro do Autismo (TEA) costumam comprometer o funcionamento adaptativo e desenvolvimento psicossocial na infância. O objetivo deste estudo foi buscar associações entre: sinais precoces dos TEA, falhas na atenção compartilhada-AC e atrasos de desenvolvimento. Participaram do estudo 92 crianças (16-24 meses) de cinco creches de Barueri-SP. Instrumentos utilizados: Development Screening Test-DENVER-II (desenvolvimento neuropsicomotor), Modified Checklist for Autism in Toddlers-M-CHAT (sinais precoces de TEA), Pictorial Infant Communication Scales-PICS(comunicação social). Identificou-se 28,3% de atrasos no desenvolvimento neuropsicomotor. Cinco crianças apresentaram sinais precoces dos TEA; todas falharam nas provas de AC (PICS). Nas crianças que apresentaram sinais indicativos de TEA, os déficits mais comuns foram relacionados à atenção compartilhada, área que deve ser privilegiada em avaliações precoces.

ABSTRACTThe Autism Spectrum Disorders (ASD) usually impair adaptive functioning and psychosocial development in childhood. The purpose of this study was to investigate associations among early signs of ASD, failures in joint attention (JA) and developmental delays. Participants were 92 children (16-24 months of age) from five day-care centers in Barueri-SP. Assessment instruments used: Development Screening Test-DENVER-II (child development); Modified Checklist for Autism in Toddlers-M-CHAT (screening for ASD); Pictorial Infant Communication Scales-PICS (social communication). Developmental delays were observed in 28.3% of the children. Five children showed early signs of ASD, all with deficits in joint attention. Since among children with early signs of ASD, the most common deficits were related to joint attention, this field should be privileged in early evaluations.
