Objective: There is limited evidence about the cross-cultural validity of autistic symptoms in school-aged children in Brazil. We used data from a large school survey to evaluate the factor structure of autism symptoms in community-dwelling children and adolescents. Methods: We translated the Childhood Autism Spectrum Test to Brazilian Portuguese and performed factor analyses to investigate the factor structure of parent-reported autistic symptoms in a large sample (n=8,571) of children/adolescents from a school survey in the metropolitan area of São Paulo. Results: Autistic symptoms were best conceptualized under a correlated-factors model with two factors: one predominantly characterized by social-communication symptoms and the other by symptoms of inflexible/restricted language, behaviors, and interests. Conclusions: These findings provide evidence that the structure of autistic symptoms in Brazil is similar to that described in other countries, indicating the cross-cultural validity of autism in Brazil.

Resumo O presente estudo populacional de corte transversal teve como objetivo verificar a prevalência de problemas de saúde mental (PSM) e descrever o uso de serviços de saúde numa amostra de crianças atendidas em unidades de saúde (UBS) do município de São Paulo. Responsáveis de 825 crianças de 6-11 anos de idade foram entrevistados. PSM das crianças foram avaliados pelo “Strength and Difficulties Questionnaire” e uso de serviços por uma versão adaptada do “Client Service Receipt Inventory Children’s version”. A prevalência de PSM internalizantes e externalizantes foi de 30,7% e 18,3%, respectivamente. O pediatra foi o profissional de saúde mais consultado (56,7%), o psicólogo foi o profissional da saúde mental mais consultado (7,9%). Apenas 3 crianças estavam em tratamento medicamentoso para PSM. A alta prevalência de PSM em crianças atendidas na AP e o baixo número de atendimentos em serviços configuram um importante problema de saúde pública. Programas de capacitação para profissionais são importantes para aprimorar a identificação e o encaminhamento de casos de PSM.

Abstract The present population study aimed at identifying the prevalence of mental health problems (MHP) and describing health services use in a sample of children attending Primary Healthcare Units (PHU) in the city of Sao Paulo. Caregivers of 825 6-11 years old children were assessed. MHP were assessed with the Strength and Difficulties Questionnaire and health services use with an adapted version of the Client Receipt Inventory Children`s version. Prevalence of internalizing and externalizing MHP was 30.7% and 18.3%, respectively. Pediatricians were the most consulted health professional (56.7%) and psychologists the most consulted mental health professional (7.9%). Only 3 children were under medication treatment for MHP. The high prevalence of MHP among children in the primary care setting and the low rate of treatment constitute a public health problem. Training programs for health professionals are relevant to help identify and refer MHP cases.

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder, often associated with other psychiatric comorbidities, functional impairments, and poor long-term outcomes. The objective of this selected review is to describe current advances and challenges in the diagnosis and treatment of ADHD. The disorder is associated with neurobiological underpinnings and is highly heterogeneous in various aspects, such as symptom profiles, cognitive impairments, and neurobiological and genetic features. The efficacy and safety of short-term pharmacological treatments across the life cycle is well studied, but further research investigating long-term treatment, impact of treatment in preschoolers, and non-pharmacological interventions is needed. Future research is also needed to better characterize the neurodevelopmental pathways of the disorder, linking clinical and neurobiological information, less investigated populations, and new interventions.
