O Sistema de Vigilância Alimentar e Nutricional (SISVAN) objetiva monitorar as características do consumo alimentar de indivíduos atendidos pelo Sistema Único de Saúde. O objetivo deste estudo foi identificar as práticas alimentares de crianças menores de 24 meses que frequentam Unidades Básicas de Saúde (UBS), utilizando o SISVAN, e avaliar a relação com perfis sociodemográficos maternos. Estudo transversal que avaliou 350 crianças utilizando-se o Formulário de Marcadores de Consumo Alimentar do SISVAN, e dados sociodemográficos maternos para a identificação dos perfis a partir da análise fatorial exploratória. Das crianças avaliadas, 41,1% das menores de 6 meses e 98,7% daquelas entre 6 e 23 meses apresentaram consumo inadequado. Foram encontrados 2 perfis sociodemográficos: Perfil 1 (mães com menor renda, menor escolaridade e beneficiárias do Programa Bolsa Família) associado com o consumo de água/chá, leite de vaca e papa salgada; e Perfil 2 (mães com mais idade, com maior número de filhos e com maior número de residentes no domicílio) associado com o consumo de leite materno (p= 0,048). A utilização do SISVAN possibilitou identificar que as crianças apresentaram práticas alimentares inadequadas, e o Perfil 1 parece ser um perfil de risco para o desmame.

The objective of the Food and Nutrition Surveillance System (SISVAN) is to monitor the food intake of individuals attended by the Brazilian Unified Health System (SUS). The objective of this research was to identify the feeding practices of children under 24 months of age who were attended at Primary Healthcare Units (UBS), using SISVAN, and to assess the relationship with maternal sociodemographic profiles. A cross-sectional study was conducted in order to evaluate 350 children using the Food Consumption Marker Form of SISVAN, and maternal demographic data to identify sociodemographic profiles by exploratory factor analysis. Of the children assessed, 41.1% were under 6 months of age and 98.7% of those between 6 and 23 months had an inadequate intake. Two sociodemographic profiles were found: Profile 1 (mothers with lower income, less education, and recipients of the 'Bolsa Família' conditional family grant program) associated with the consumption of water/tea, cow's milk and salty baby food; and Profile 2 (older mothers with many children and with a larger number of residents in the household) associated with breast milk consumption (p = 0.048). The use of SISVAN made it possible to identify that children had inadequate feeding practices, and Profile 1 appears to be a risk profile for weaning.

A validity test of a Food Frequency Questionnaire was carried out using 50 students of health occupation in São Paulo, Brazil. Therefore, a three day dietary record was used as reference method and variables such as energy, macronutrients and dietary fiber were analyzed. The accordance between the Food Frequency Questionnaire and average data from dietary record was tested with kappa statistics and intra-class correlation coefficients (ICC). Limits of agreement were estimated by the Bland-Altman's method. Better results were found for calories (ICC 0.43; 95%CI 0.17 - 0.63) and non-energy-adjusted nutrients, except dietary fiber (ICC 0.34; 95%CI 0.07 - 0.56). The percentage of individuals classified in the same category of consumption was nearly half (49.8%), while only 16% of them were classified in opposite categories. With the exception of lipids, other analyzed variables tended to be overestimated by the Food Frequency Questionnaire. The Food Frequency Questionnaire is recommended as a method of assessing food intake of university students in studies which focuson calorie estimates and also intend to classify groups into intake categories.
