An epidemiological survey of the prevalence of xerophthalmia was conducted in the state of Paraiba through 10,922 clinical examinations of 0 to 12 yr old children from six localities representative of the three different ecological regions of Paraiba. The regional distribution of clinical signs of vitamin A deficiency was markedly different, and in the semiarid region (Sertão) the prevalence reached levels suggesting that it was a public health problem in that area. Seasonal variations were observed and were specially significant in the "Sertão," with xerophthalmia signs appearing more frequently during the interharvest period. This seems to be the first report with documented active cases of xerophthalmia in this region of Brazil.
ObjetivoAvaliar o impacto da suplementação da dieta com multimistura sobre o estado nutricional de crianças em fase pré-escolar em risco nutricional.
MétodosTrata-se de estudo tipo duplo cego com duração de dois meses e acompanhamento longitudinal de 135 crianças na faixa etária de um a seis anos. As crianças foram divididas em três grupos: intervenção 1 (GI1 n=48), intervenção 2 (GI2 n=45) e controle (GC n=42), recebendo 5g e 10g de multimistura e placebo, respectivamente.
