Ensaio randomizado sobre o impacto da multimistura no estado nutricional de crianças atendidas em escolas de educação infantil

Abstract

Objective: To evaluate the effect of adding a nutritional supplement "multimixture" to school meals on the nutritional status of children enrolled at municipal preschools. Methods:Longitudinal, controlled intervention study of 24 preschools which were compared before and after an intervention. The control and intervention groups were defined by drawing lots to choose schools that had previously been paired for nutritional status. The intervention consisted of the addition of 10 g of multimixture to the meals provided to children attending the 12 schools in the intervention group. Outcome measures include changes in z scores for the three nutritional indices and hemoglobin values over the 6-month period during which the supplement was added. A multilevel model was used for analyses.Results: Mean z scores for weight for age at the end of follow-up were 0.40 (±1.34) and 0.31 (±1.32) for the intervention and control groups, respectively. The multilevel analysis demonstrated non-significant differences in favor of the intervention in mean z scores for weight for age (β 0.05; 95%CI -0.03 to 0.12) and height for age (β 0.02; 95%CI -0.06 to 0.09). Mean change in hemoglobin was against the intervention, but this was also without significance (β -0.01; 95%CI -0.36 to 0.34). Conclusions:Supplementation with 10 g of multimixture did not have a significant effect on any of the nutritional indices or measurements of the municipal preschool pupils studied here.J Pediatr (Rio J). 2007;83(4):363-369: Children, dietary supplements, clinical trial.

Antioxidant and Anticancer Activity of Spirulina platensis Water Extracts

“…In order to meet this demand, it is important to study sources of fibers and antioxidants compounds that are technology viable, with positive environmental and economic impacts (Bolanho et al, 2014). In recent years, there has been an explosive interest in the use of antioxidants nutritional supplements (Gigante et al, 2007). Epidemiological evidence suggests that intake of some vitamins, minerals and other food constituents may help to protect the body against heart disease, cancer and the aging process and that antioxidants may have a protective effect, either in preventing these diseases or lessening their severity (Hsia et al, 2007).…”

Análise Química e Microbiológica da Multimistura

“…Essa afirmação pode ser comprovada pelo estudo de Oliveira et al (2006), o qual mostrou que a suplementação com a multimistura por dois meses não alterou, significativamente, o estado nutricional de pré-escolares. Resultados semelhantes foram obtidos por Gigante et al (2007), em que a suplementação com multimistura por seis meses não mostrou efeito significativo sobre nenhuma das medidas ou índices nutricionais estudados em crianças atendidas em escolas municipais de Educação Infantil. Estudos com animais têm mostrado os mesmos resultados insatisfatórios do impacto do produto na recuperação do estado nutricional (LEITE et al, 2002;MADRUGA et al, 2004;KAMINSKI et al, 2008).…”

Efeitos do consumo da multimistura sobre o estado nutricional: ensaio comunitário envolvendo crianças de uma favela da periferia de Maceió, Alagoas, Brasil

“…Concluíram que não houve alteração significativa no estado nutricional após dois meses de suplementação. Gigante et al 25 também concluíram pela inefetividade da multimistura ao conduzirem estudo de intervenção, longitudinal e controlado, incluindo crianças de 24 escolas de educação infantil que foram comparadas antes e depois da intervenção, tendo como indicadores parâmetros antropométricos e o nível de hemoglobina.…”
