Resumo: | The study describes the relationship between anthropometric status, socioeconomic conditions, and quality of home environment and child cognitive development in 320 children from 20 to 42 months of age, randomly selected from 20,000 households that represent the range of socioeconomic and environmental conditions in Salvador, Bahia, Northeast Brazil. The inclusion criterion was to be less than 42 months of age between January and July 1999. Child cognitive development was assessed using the Bayley Scales for Infant Development, and the Home Observation for Measurement of the Environment Inventory (HOME) was applied to assess quality of home environment. Anthropometric status was measured using the indicators weight/age and height/age ratios (z-scores), and socioeconomic data were collected through a standard questionnaire. Statistical analysis was conducted through univariate and hierarchical linear regression. Socioeconomic factors were found to have an indirect impact on early cognitive development mediated by the child's proximal environment factors, such as appropriate play materials and games available and school attendance. No independent association was seen between nutritional status and early cognitive development. |

O critério de inclusão foi ter menos de 42 meses entre janeiro e julho de 1999. O desenvolvimento cognitivo foi avaliado pela escala Bayley de desenvolvimento infantil, e o inventário HOME de observação doméstica avaliou a qualidade do ambiente doméstico. Os indicadores peso/idade e altura/idade (escores-z) identificaram o estado antropométrico, e as informações sócio-econômicas foram obtidas utilizando-se questionário padronizado. Utilizou-se a técnica da regressão linear univariada e regressão linear hierarquizada para as análises estatísticas. Encontrou-se que os fatores sócio-econômicos influenciam o curso do desenvolvimento cognitivo na primeira infância de maneira indireta, sendo mediados por fatores do contexto proximal da criança, como disponibilidade de materiais e jogos adequados e freqüência escolar. Não se encontrou uma associação independente entre estado nutricional infantil e desenvolvimento cognitivo na primeira infância.Reports in Public HealthCadernos de Saúde Pública2008-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/3802Reports in Public Health; Vol. 24 No. 2 (2008): FebruaryCadernos de Saúde Pública; v. 24 n. 2 (2008): Fevereiro1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/3802/7713https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/3802/7714Santos, Letícia Marques dosSantos, Darci Neves dosBastos, Ana Cecília SousaAssis, Ana Marlúcia OliveiraPrado, Matildes SilvaBarreto, Mauricio L.info:eu-repo/semantics/openAccess2024-03-06T15:27:50Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/3802Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:04:22.077741Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
