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.

El objetivo de este estudio fue investigar el bie-nestar en una muestra aleatoria de nutricionistas, utilizando la imagen corporal y las variables sociales y personales como factores causales, en un estudio exploratorio y transversal. El trabajo estadístico incluyó análisis descriptivos, pruebas t, ANOVAs y regresión lineal. Los 242 participantes manifestaron gozar frecuentemente de bienestar en el trabajo (M=3.8); el 25,6% presentó una imagen corporal levemente distorsionada; el 14,5% moderadamente distorsionada y el 7,5% severamente distorsionada. Las variables sociales y personales, como tener hijos y los ingresos personales, se asociaron con el bienestar. La imagen corporal tuvo un impacto significativamente negativo sobre el 3.2% del bienestar.

The objective of this study was to investigate wellbeing in a random sample of nutritionists, using body image, and social and personal variables as causal factors, in an exploratory, cross-sectional study. Statistical treatments included descriptive analyses, t-tests, ANOVAs, and linear regressions. The 242 participants perceived themselves frequently in a wellbeing state at work (M=3.8); 25.6% of participants presented a mildly distorted body image, 14.5% a moderately distorted body image, and 7.5% a severely distorted body image. Social and personal variables, such as having children and the level of personal income, were associated with wellbeing. Body image had a significant negative impact of 3.2 % on wellbeing.

O trabalho estatístico incluiu análise descritiva, provas-t, ANOVAs e regressão linear. Os 242 participantes manifestaram gozar de bem-estar no trabalho com frequência (M=3,8); 25,6% apresentaram uma imagem corporal levemente distorcida; 14,5% moderadamente distorcida e 7,5% seriamente distorcida. As variáveis sociais e pessoais -ter filhos, ingressos pessoais, campo de trabalho, grupo etário e atividade física regular- se associaram com o bem-estar. A imagem corporal tem um impacto significativamente negativo sobre o bem-estar.

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.

OBJETIVO: Comparar o estado nutricional de lactentes de ambos os sexos de acordo com a curva proposta pelo Centers for Disease Control and Prevention (CDC-2000) e com a nova curva de crescimento proposta pela Organização Mundial da Saúde (OMS-2006). MÉTODOS: Estudo longitudinal no qual foram acompanhadas crianças de ambos os sexos, nascidas a termo, com idade entre seis meses e um ano, em aleitamento materno predominante ou exclusivo. Os dados foram coletados por um único pesquisador por meio de ficha de atendimento nutricional composta por dados demográficos, antropométricos e sobre a alimentação da criança. Foram realizados testes de Wilcoxon e Friedman para comparar cada medida das curvas e analisar a variância, respectivamente. RESULTADOS: Da amostra final de 55 crianças, 51% (n=28) eram do sexo masculino. Os percentuais de eutrofia dos índices de peso por idade e de estatura adequada para idade de ambos os sexos apresentaram-se acima de 80%. Não houve diferença significante na classificação do estado nutricional, segundo as curvas utilizadas. A porcentagem de concordância das duas curvas em relação ao peso e à estatura foi de 98,2 e 96,4%, respectivamente. CONCLUSÕES: As curvas de crescimento da OMS-2006 e do CDC-2000 foram similares para classificar o estado nutricional de lactentes entre 6-12 meses em aleitamento materno.

OBJECTIVE: Compare the nutritional status of male and female infants classified according to the growth curve proposed by the Center for Disease Control and Prevention (CDC-2000) and the new growth curve proposed by the World Health Organization (WHO-2006). METHODS: This longitudinal study enrolled children of 6-12 months old of both genders. They were born at term and exclusively or predominantly breastfed. A single researcher collected demographic, anthropometric and nutritional data. The Wilcoxon test was used to compare curves and the Friedman test was used to analyze the variance. RESULTS: Among the 55 followed children, 51% (n=28) were males. The percentages of normal weight-for-age and proper height-for-age in both genders were above 80%. The nutritional status classification according to both growth curves was similar. Agreement between the two curves regarding weight and height was 98.2 and 96.4%, respectively. CONCLUSIONS: CDC-2000 and WHO-2006 growth curves were similar regarding nutritional status classification of 6-12 months old breastfeed infants.

Objetivo Desenvolver e aplicar em um projeto-piloto um questionário de frequência alimentar quantitativo de autopreenchimento destinado a graduandos da área da saúde. Métodos Trata-se de um estudo transversal realizado em 151 universitários de ambos os sexos, usuários do ambulatório de Nutrição do Corpo Discente da Universidade Federal de São Paulo, Brasil. O questionário inicial foi composto a partir dos alimentos e preparações informados no Registro Alimentar de Três Dias. As informações em medidas caseiras foram transformadas em gramas ou mililitros com o auxílio de tabelas, e os alimentos foram ordenados segundo a porcentagem de contribuição para o valor energético total informado. Foram selecionados 198 ali-mentos responsáveis por 95% do consumo energético e agrupados em 77 itens alimentares de acordo com a similaridade nutricional. O tamanho das porções alimentares foi classificado conforme o valor do percentil 50 da distribuição dos pesos correspondentes às medidas caseiras referidas. Definiu-se como porção pequena, aquela cujo valor foi igual ou inferior ao percentil 25; como média, o percentil 50 e grande, o valor igual ou superior ao percentil 75. Resultados Após o pré-teste do questionário inicial, o questionário final resultou em uma lista com 89 alimentos, agrupados em 70 itens alimentares. As instruções para o autopreenchimento foram refeitas, objetivando-se um melhor preenchimento. Conclusão Após as modificações realizadas, o questionário de frequência alimentar quantitativo encontra-se pronto para o estudo de validação e calibração.

Objective The objective of this study was to develop and pretest a self-administered, quantitative food frequency questionnaire for undergraduate students of the health sciences. Methods This is a cross-sectional study with 151 undergraduate students of both genders from the Students' Healthcare Service of the Universidade Federal de São Paulo, Brazil. The first version of the food frequency questionnaire was based on the foods and preparations listed in the 3-day food records. Tables were used to convert cooking units into grams or milliliters and the foods were ranked according to their percentage contribution to the total calorie intake. The 198 foods responsible for 95% of the energy intake were selected and grouped into 77 food items according to nutritional resemblance. Serving size was classified according to the 50th percentile of the weight distribution corresponding to the cooking units. Serving size was defined as small (S) when £25th percentile; average (A) when equal to the 50th percentile and large (L) when ≥75th percentile. Results The pretest of the first version of the questionnaire resulted in a final version with a list of 89 foods, grouped into 70 food groups. The instructions for filling out the questionnaire were rewritten to get better answers from the students. Conclusion After these changes, the quantitative food frequency questionnaire is ready for the validation and calibration study.
