Resumo: | Two cohorts of children born in the city of Pelotas, Southern Brazil, in 1993 and 2004, were compared in terms of neuro-psychomotor development at the age of 12 months. Children were evaluated using the Denver II screening test. Analyses were performed using the Poisson regression technique. The prevalence of suspected developmental delay fell from 37,1% in 1993 to 21.4% in 2004 and was inversely proportional to family income and birth weight. Among children born weighing under 2,000 g, there was a fourfold reduction in the prevalence of developmental delay between 1993 and 2004. With regard to family income, the poorest group showed the greatest reduction between the two cohorts - a 30% reduction in risk. Our results confirm the influence of income and birth weight on child development. The decrease in the prevalence of developmental delay in the last decade reflects, among other factors, improvements in neonatal care, increased coverage of developmental monitoring in the first year of life, and longer breastfeeding duration. Despite this reduction, the prevalence of developmental delay is still high, reinforcing the need for early diagnosis and intervention. |

As crianças foram avaliadas pelo teste de triagem de Denver II. As análises foram realizadas usando a técnica de regressão de Poisson. A prevalência de suspeita de atraso no desenvolvimento diminuiu de 37,1% em 1993 para 21,4% em 2004, e era inversamente proporcional à renda familiar e ao peso ao nascer. Entre crianças com peso ao nascer abaixo de 2000g, houve uma redução de quatro vezes no atraso no desenvolvimento, entre 1993 e 2004. Com relação à renda familiar, o grupo mais pobre mostrou a maior redução entre as duas coortes - uma redução de 30% no risco. Nossos resultados confirmam a influência de renda e peso ao nascer sobre o desenvolvimento infantil. A queda na prevalência de atraso no desenvolvimento na última década reflete, entre outros fatores, melhorias na assistência pré-natal, aumento de cobertura no monitoramento do desenvolvimento no primeiro ano de vida e maior duração do aleitamento materno. Apesar dessa redução, a prevalência de atraso no desenvolvimento permanece alta, reforçando a necessidade de diagnóstico precoce e intervenção.Reports in Public HealthCadernos de Saúde Pública2008-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/3785Reports in Public Health; Vol. 24 No. 15 (2008): Supplement 3Cadernos de Saúde Pública; v. 24 n. 15 (2008): Suplemento 31678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/3785/7680https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/3785/7679Halpern, RicardoBarros, Aluísio J.
