ABSTRACT

The goal of the study was to assess public school children at the end of the first stage of elementary school. We used a protocol applied concurrently with a writing test in the form of an unexpected activity in 28 public schools; 2,893 children assessed, 687 exhibited performance below 58 points, 184 were excluded due to change of address or lack of consent; 503 children subjected to a test of intellectual capacity and reading assessment and 71 considered intellectually disabled were excluded. 226 (7.8%) children, who could read, write, and had normal intellectual level, met the criteria of developmental dyscalculia (DD), 98 female and 128 male. The most influential factors in the prevalence were socioeconomic levels of the schools neighborhood, education level of parents, and being male, as demonstrated by the odds ratio and multiple logistic regression analysis. Further studies should be done so that educational policies are taken.

RESUMO

Este estudo teve como objetivo avaliar crianças da rede pública no final da 1a etapa do ciclo fundamental; com um protocolo aplicado em forma de atividade surpresa em 28 escolas públicas, concomitantemente a uma prova de escrita: Das 2893 crianças avaliadas, 687 tiveram rendimento abaixo de 58 pontos, 184 foram excluídas por mudança de domicilio ou por falta de consentimento; 503 submetidas a um teste de avaliação intelectual e de leitura, 71 consideradas intelectualmente deficientes foram excluídas do estudo. 226 (7,8%) sabiam ler e escrever e intelectualmente normais, preenchendo os critérios para o diagnóstico de discalculia do desenvolvimento (DD), 98 do sexo feminino e 128 masculinos. Fatores que mais influenciaram na prevalência da DD foram os níveis socioeconçmicos do bairro da escola, nível de escolaridade dos pais e sexo masculino, demonstrados pela Odds Ratio e Analise de regressão logística múltipla. Mais estudos devem ser realizados para que políticas educacionais sejam tomadas.
