The results show that approximately 50% of the municipalities evaluated are in a positive situation in relation to the local procurement for PNAE. However, the number of municipalities that did not publish the public call or not signed the contract is still important and deserves attention of the sectors involved.

Abstract

O objetivo do estudo foi identificar o custo necessário para a obtenção de uma dieta saudável no Brasil e analisar o comprometimento dessa prática na renda familiar. Foram utilizados dados da Pesquisa de Orçamentos Familiares de 2008. Aquisições de alimentos foram coletadas durante sete dias em 55.970 domicílios. Dois subconjuntos compostos apenas por famílias de baixa renda (≤ R$ 415,00 per capita/mês e ≤ US$ 1,00 per capita/dia) foram analisados. A partir dos alimentos obtidos, foram calculados calorias, despesa com alimentação e o preço médio dos oito grupos alimentares presentes no Guia Brasileiro. Foram comparados os gastos atuais e ideais para os oito grupos. As obtenções excederam às recomendações para feijões, óleos/gorduras, doces, carnes/ovos e não alcançaram as recomendações para frutas, hortaliças, lácteos e cereais. Atingir as recomendações aumentaria os gastos com a alimentação em 58%, para indivíduos de renda/per capita de ≤ US$ 1,00 per capita/dia, e em 39%, para indivíduos com renda ≤ R$ 415,00, e comprometeria em 145% a renda familiar. Brasileiros de menor poder aquisitivo necessitam aumentar a renda para atingir a dieta ideal.

ObjectiveTo analyse the Nutritional Knowledge Test (NKT) using Item Response Theory (ITR) analysis and to assess the construct validity of the Nutritional Knowledge Scale (NKTS) and its associations with adolescent food group consumption and nutritional biomarkers.DesignCross-sectional study.SettingMulticentre investigation conducted in ten European cities.ParticipantsAdolescents aged 12·5–17·5 years (n 3215) who completed over 75 % of the NKT.ResultsFactor analysis indicated that the NKT can be analysed with a one-dimensional model. Eleven out of twenty-three items from the NKT presented adequate parameters and were selected to be included in the NKTS. Nutrition knowledge was positively associated with consumption of fruits, cereals, dairy products, pulses, meat and eggs, and fish, as well as with blood concentrations of vitamin C, β-carotene, n-3 fatty acids, holo-transcobalamin, cobalamin and folate; nutrition knowledge was negatively associated with intake of olives and avocado, alcohol and savoury snacks.ConclusionsThe NKTS assessed nutritional knowledge adequately and it is proposed as a new tool to investigate this subject in future studies.

Neste texto apresentamos as dietas sustentáveis, os sistemas alimentares e sua relação com saúde e nutrição. Uma dieta de qualidade é aquela que elimina a fome, é segura, reduz todas as formas de desnutrição, promove a saúde e é produzida de forma sustentável, ou seja, sem prejudicar o ambiente e garantindo dietas de alta qualidade também para as gerações futuras. Não é possível ter uma alimentação saudável sem que esta seja sustentável em todas as suas dimensões. No entanto, o sistema alimentar global, hoje, não é sustentável e, paralelamente, o mundo enfrenta a sindemia global da obesidade, desnutrição e mudanças climáticas. Para a superação dos desafios será necessário olhar para os sistemas de produção, as atividades da cadeia de suprimentos, os ambientes alimentares, o consumo alimentar e o comportamento dos consumidores, envolvendo múltiplos atores.

The scope of this study was to identify patterns of physical activity and sedentary behavior (PPASB) in adolescents enrolled in public schools and assess possible relationships between these patterns and overweight. This is a Cross-sectional study conducted in 2009, with the representative sample of adolescents enrolled in the fifth grade in public schools of Piracicaba, São Paulo (Brazil) consisted of 454 adolescents between 10 and 14 years of age. Physical activity, sedentary behavior and food intake information was collected through questionnaires. Anthropometric data were also collected (body mass and height). PPASB were identified through Principal Component Analysis. To characterize the association between PPASB and overweight, multiple binary logistic regression models were used. Out of 454 adolescents, 53.5% were female and 36.6% were overweight. Six PPASB were identified: 1) composed by volleyball and dance; 2) composed by soccer, video-game and computer; 3) composed by television and computer; 4) composed by dodge-ball and cycling; 5) composed by walking activity and 6) composed by gymnastics. The PPASB characterized by sedentary activities (television and computer) was associated with overweight (OR: 1.22, 95% CI: 1.02-1.46) after adjusted by sexual maturity, energy density and gender. In conclusions, taking a PPASB characterized mainly by spent time in front of the television and computer increases the chance of developing overweight.
