“…6 Review studies on vitamin A deficiency in children younger than six years old showed rates between 16 and 74%, 7 this may be a cause for concern 8 and is a severe public health problem in the North, Northeast and Southeast regions of Brazil, making the children form the Northeast the most vulnerable to endemic deficiencies. 9,10 However, there are a few studies in Bahia and those that exist are dated back to more than 10 years ago.

Estado nutricional de vitaminas A e D em crianças participantes de programa de suplementação alimentar

Porém, essas associações ainda são controversas na literatura 23,24 .…”
