Resumo: | The aim of this study was to determine the contribution of individual and school characteristics to the variability in body mass index (BMI) z-scores of 7 to 10 years old children. Anthropometric and sociodemographic data from two cross-sectional studies conducted with schoolchildren from the 2nd to the 5th grades of elementary schools were analyses (n = 2,936 in 2002, and n = 1,232 in 2007). Multilevel modeling was used to estimate variations in BMI at child and school levels. The contribution of the school context to the overall variability of BMI z-score was small but significant in 2002 (3.3%-4.4%) and in 2007 (2.4%-5.3%), showing that schoolchildren from private schools had a higher BMI compared to those from public schools. The monthly family income showed, in general, a negative association with BMI z-score in 2002 and a positive association in 2007, for both sexes. The consumption of sweets showed a negative effect in the BMIs of children. In both surveys, overweight/obese mothers and excessive birth weight were positively associated with BMI z-score. Mother’s weight status had a higher influence on the overall variability of BMI in both surveys. In conclusion, school and child characteristics contributed to the variance in children’s weight status. The results imply that overweight/obesity childhood prevention programs should focus on strategies of family engagement to be more effective. |

Se analizaron datos antropométricos y sociodemográficos de dos estudios transversales conducidos con escolares de la segunda a la quinta serie de la enseñanza fundamental (n = 2.936 en 2002 y n = 1.232 en 2007). Se utilizaron modelos multinivel para estimar variaciones en el IMC en los niveles infantiles y escolares. La contribución del contexto escolar para la variabilidad general de IMC z-score fue pequeña, pero significativa en 2002 (3,3%-4,4%) y en 2007 (2,4%-5,3%), indicando que los escolares de escuelas privadas tenían un IMC superior, comparados con los de las escuelas públicas. Los ingresos familiares mensuales mostraron, en general, una asociación negativa con el IMC z-score en 2002 y una asociación positiva en 2007, para ambos sexos. El consumo de dulces mostró un efecto negativo en el IMC de los niños. En ambas encuestas, las madres con sobrepeso/obesas y el peso excesivo al nacer se asociaron positivamente con el IMC z-score. El estatus del peso de la madre tuvo una influencia más alta en la variabilidad general del IMC en ambas encuestas. En conclusión, las características escolares y del niño contribuyeron a la variancia en el estatus de peso de los niños. Los resultados implican que los programas infantiles de prevención de sobrepeso/obesidad deberían enfocarse en estrategias de adhesión familiar para ser más efectivos.O estudo teve como objetivo medir a contribuição das características individuais do aluno e da escola à variabilidade dos escores-z do índice de massa corporal (IMC) em crianças brasileiras entre 7 e 10 anos de idade. Foram analisados dados antropométricos e sociodemográficos de dois estudos trnasversais conduzidos com escolares da segunda à quinta série de Ensino Fundamental (n = 2.936 em 2002 e n = 1.232 em 2007). A modelagem multinível foi utilizada para estimar as variações de IMC em nível individual e de escola. A contribuição do contexto escolar à variabilidade global do escore-z do IMC foi pequena, porém significativa, em 2002 (3,3%-4,4%) e em 2007 (2,4%-5,3%), mostrando que alunos de escolas particulares tinham IMC mais alto, comparado ao dos alunos de escolas públicas. A renda familiar mensal mostrou uma associação negativa com o escore-z do IMC em 2002 e uma associação positiva em 2007, para ambos sexos. O consumo de doces mostrou efeito negativo sobre o IMC das crianças. Em ambos estudos, filhos de mães com sobrepeso/obesidade e alunos com história de excesso de peso ao nascer mostraram associação positiva com o escore-z do IMC. Em ambos estudos, o estado nutricional materno mostrou influência maior sobre a variabilidade global do IMC. Em conclusão, as características da escola e do aluno contribuíram para a variância no IMC da criança. Os resultados sugerem que, para serem mais eficazes, os programas de prevenção de sobrepeso/obesidade na infância devem focar em estratégias com participação da família.Reports in Public HealthCadernos de Saúde Pública2018-05-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6855Reports in Public Health; Vol. 34 No. 5 (2018): MayCadernos de Saúde Pública; v. 34 n. 5 (2018): Maio1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6855/14842https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6855/14843Danielle Biazzi LealMaria Alice Altenburg de AssisWolney Lisboa CondeAdriana Soares LoboFrance BellisleDalton Francisco de Andradeinfo:eu-repo/semantics/openAccess2024-03-06T15:29:34Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/6855Revistahttps://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:2024-03-06T13:07:51.012647Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
