“…29 As well as other deficiencies problems, vitamin A deficiency is associated to socioeconomic factors and more prevalent in less fortunate regions. 10,19 However, no association was found on income with inadequate levels of retinol in this present study, similar found in other studies. 3,21,26,28 It is likely that the homogeneity displayed by the studied population has made it difficult to identify these statistical associations.…”

In addition, there were no studies conducted in the city of Vitória da Conquista, the third largest city in Bahia, characterized as an endemic area for hypovitaminosis A.…”

“…A principal causa da deficiência de vitamina A está relacionada à dieta cronicamente insuficiente em vitamina A, que pode levar a baixos estoques corporais e a falhas em atender as necessidades fisiológicas 6,13,14,15 , além disso, outros fatores têm sido tratados, na literatura, como possíveis preditores das concentrações séricas de vitamina A, como as condições socioeconômicas e ambientais 16,17,18,119 , características maternas 20 , peso ao nascer 21 e indicadores antropométricos 17,22 . Porém, essas associações ainda são controversas na literatura 23,24 .…”
