Abstract: Anemia is a public health issue with relevant consequences for the health of human beings. It is a result of bad nutritional conditions and health deficiency which affect the development and performance both cognitive and physical of children,their immunity and increases the risk of infections and infant mortality . The objective of this study is to identify the prevalence of anemia in children who attend nurseries in Child day care centers and its correlated factors. It consists of a cross-sectional study with 334 children between seven months old and three years old who attend child day-care centers in Colombo, in the metropolitan area of Curitiba , Paraná.A representative sample of children who attend nurseries in the area was selected, that is , 320 children , being defined by stratified sampling according to conglomerations in the same stage, within 26 Child day care centers chosen at random.To obtain the information needed, a meeting with these children's parents was held for the signature of the Termo de Consentimento Livre e Esclarecido ( TCLE ) and to fill in a questionnaire to investigate their socioeconomic conditions , environmental conditions and health conditions. A digital puncture was done in the children to check their level of hemoglobin and it was considered anemia when there was less than 11g/dL of it. The consumption of iron was obtained by weighting meals in the CMEIs. The eating practice in the household was achieved through a questionnaire which investigated the current consumption of some kinds of food and at what age they were introduced. Weight and stature were considered for evaluation of the nutritional condition. An association test was carried out along with the qui-square test ( X2) . The Odds Ratio ( O.R. ) was estimated. The significance level chosen for the analysis was p<0,05 ( p = value ) and the confidence interval of 95%. The variables equal to p<0,20 in the qui-square test ( X2 ) were selected for the analysis of multiple logistic regression. The prevalence of anemia found is 34,7 %. There is more risk of anemia in children whose mothers are under 28 years old , masculine gender , under 24 months old , and who do not consume iron sources (meat+beans+dark green vegetables).There was no relation between anemia and consumption of iron in food in the child day care centers , but the consumption of iron was much lower than it is recommended by the resolution of Fundo Nacional de Desenvolvimento da Educação ( FNDE ), being possible to observe more prevalence of anemia in children whose consumption of iron , heme iron and non-heme iron were below the average. In terms of Public Health, the prevalence of anemia is a moderate problem in the population studied and shows the need of intersectorial actions to diminish the prevalence in the child day care centers .
