Abstract
OBJETIVO: Avaliar o estado nutricional e os níveis hematológicos e séricos de ferro em pré-escolares de municípios com diferentes índices de desenvolvimento infantil (IDI). MÉTODOS: Estudo transversal de 34 pré-escolares com idade de três a seis anos do município de Laranjal, Paraná, com IDI baixo e com o mesmo número de crianças pareadas por idade e gênero, provenientes de Presidente Prudente, São Paulo, município com IDI médio. Avaliou-se o estado nutricional por meio do escore Z das relações peso/estatura e estatura/idade. A avaliação bioquímica constou de dosagens de hemoglobina, hematócrito, ferro sérico e ferritina. Para a análise estatística foram usados os testes t de Student, Mann-Whitney, qui-quadrado e o exato de Fisher. RESULTADOS: Peso, estatura e escore Z das relações antropométricas foram significantemente menores no grupo de crianças de Laranjal comparados aos de Presidente Prudente. A prevalência de anemia em ambos os grupos foi 8,8%, não havendo diferença significante para a prevalência de ferropenia e para os valores de ferritina sérica. CONCLUSÕES: Pré-escolares do município com IDI baixo apresentam mais desnutrição, enquanto sobrepeso e obesidade são predominantes nos pré-escolares do município com IDI médio. Quanto às alterações dos níveis hematológicos e séricos de ferro, não há diferença entre os pré-escolares dos municípios estudados.
OBJECTIVE: To evaluate nutritional status and iron hematological and serum levels of preschool children from cities with different child development indexes (CDI). METHODS: This cross-sectional study enrolled 34 preschool children aged between three to six years from two municipalities of Brazil: Laranjal, Paraná, with a low CDI, and Presidente Prudente, Sao Paulo, with a medium CDI. Children of both cities were matched by age and gender. The nutritional status was evaluated by Z score for weight/height and height/age. The biochemical evaluation included hemoglobin, hematocrit, seric iron and ferritin levels. The following tests were used for statistical analysis: t test, Mann-Whitney, chi-square and Fisher's exact test. RESULTS: The weight, height and Z score of the anthropometric relationships were significantly lower in the group of Laranjal children. Anemia was present in 8.8% of the children studied in both cities, without significant differences in the prevalence of iron deficiency or in the ferritin levels. CONCLUSIONS: The preschool children from the city with low CDI presented mainly malnutrition, while overweight and obesity were more prevalent on preschool children from the city with a medium CDI. Hematimetric values, iron and ferritin levels were similar between the preschool children of both cities.
