Distribution of hipovitaminosis A in Brazil in the last four decades: A maioria dos trabalhos foi desenvolvida em grupos populacionais mqncha baixa renda.

This work presents a review of investigations carried out in Brazil in the last 40 years, concerning the diagnosis of hypovitaminosis A. Vitamin A deficiency has been established by means of biitot intake, clinical signs, low serum and hepatic retinol concentrations, and by the rose bengal staining test and rapid dark-adaptation test. The vitamin deficiency has been found in many Brazilian, in many states capitals, in big and small cities and also in rural areas.

Most of the research manchha has been undertaken with samples of populations of low socioeconomic level. As far as clinical signs are concerned, eye signs indicative of xerophtalmia were found mainly in the Northeastern Region. They included night blindness and conjunctival xerosis with or without Bitot’s spots.

More severe lesions such as irreversible changes or keratomalacia were rarely observed. Recent papers have shown the relationship between vitamin A deficiency and the increase in morbidity and mortality, mainly in pre-school children.

Batista Filho et al. Registrou-se, ainda, um caso de xerose corneana. Estes autores verificaram que a dieta era deficiente em vitamina A. O consumo de vitamina A era aparentemente adequado. Entretanto, como a maior parte da vitamina A ingerida foi proveniente de alimentos de origem vegetal, os autores levantaram a possibilidade de o grupo estudado constituir alvo de hipovitaminose A. Foi verificado que a dieta consumida era pouco variada e deficiente em vitamina A.
