OBJETIVO: Avaliar a confiabilidade e a validade do uso de sinais clínicos simples de palidez palmar e de conjuntivas, como método para triagem de anemia. MÉTODOS: Estudo realizado em uma creche municipal de São Paulo, SP, com 135 crianças >3 meses e OBJECTIVE: To evaluate the reliability and the validity of the use of simple clinical signs as a method of anemia detection. METHODS: The study was carried out in a São Paulo, Brazil, day-care center, and included 135 children from ages 3 months-6 years. Hemoglobin level results and palmar and conjunctival pallor assessment were used. Children with Hb under 11g/dl were considered as anemic; subjective criteria were used for the assessment of palmar and conjunctival pallor. Kappa statistics were used in order to verify agreement, and, in order to evaluate the technique's validity, sensitivity and specificity levels were calculated. RESULTS: The results show low levels of agreement. There was a greater level of sensitivity to conjunctival pallor than to palmar pallor. Specificity results may be considered as good. CONCLUSIONS: It is still early to recommend the routine use of this technique. However, it could promote substantial savings if perfected.

OBJETIVO: Identificar a relação entre os níveis de hemoglobina e o consumo de leite materno, alimentos complementares e líquidos não nutritivos no primeiro ano de vida. MÉTODOS: Estudo transversal envolvendo 553 crianças menores de 12 meses de vida, que freqüentavam os serviços públicos de saúde. A concentração de hemoglobina foi avaliada pelo método cianometahemoglobina, usando-se o sistema HemoCue. Utilizou-se a técnica da regressão linear múltipla para avaliar as associações de interesse. RESULTADOS: Níveis de hemoglobina compatíveis com a anemia foram identificados em 62,8% das crianças investigadas, com maior ocorrência naquelas de seis a 12 meses de idade (72,6%). O aleitamento materno exclusivo nos primeiros seis meses de vida assegurou os mais elevados níveis de hemoglobina. Os demais regimes alimentares declinaram de maneira diferenciada os níveis de hemoglobina, que se tornaram compatíveis com a anemia quando o regime de aleitamento artificial foi adotado (p=0,009). O consumo de chá e/ou água declinou em 0,76 g/dl (pOBJECTIVE: To assess the relationship between hemoglobin concentration and breastfeeding and complementary feeding during the first years of life. METHODS: Cross-sectional study with 553 children under age 12 months, who attended public healthcare facilities. Hemoglobin concentration was measured by the cyanmethaemoglobin method, using the HemoCue system. Associations of interest were analyzed through multiple linear regression. RESULTS: Hemoglobin concentrations compatible with anemia were identified in 62.8% of the children studied, with greater occurrence among the 6-12 months age group (72.6%). Exclusive breastfeeding during the first six months of life was associated with the highest levels of hemoglobin. The remaining feeding regimes were associated with different levels of reduction in hemoglobin levels, which became compatible with anemia in children fed with formula (p=0,009). Tea and/or water consumption was associated with a reduction in hemoglobin concentration of 0.76 g/dl (p
