Hipovitaminose A no Brasil: um problema de saúde pública

Abstract: Vitamin A deficiency is considered one of the most important of the easily preventable public health problems in a number of countries, including Brazil.

“…18 Analyzing the water-infection variable, the importance of contributing factors to the occurrence of VAD can be observed, such as the high prevalence of infections, lack of sanitation and drinking water, as well as adverse socioeconomic conditions and taboos related to food of plant origin which increase the demand or interfere in the organism's intake and metabolizing of Vitamin A. 13 The results of this study show that, in spite of actions to prevent and control VAD on the part of the state of Paraíba, it is still a serious public health problem, demanding specialist attention from the government organizations which deal the population's health and nutrition. In this context, it is necessary to consider the importance of concerted actions covering sanitation, immunization and the control of diarrheal and parasitic diseases as a form of preventing and controlling Vitamin A defi ciency.…”

“…O Brasil é apontado como uma região de risco de deficiência de vitamina A subclínica 4 . Essa afirmação é sustentada por resultados de estudos realizados a partir da década de 70, que avaliam a situação da hipovitaminose A nas regiões Sudeste (São Paulo, Rio de Janeiro e Minas Gerais) 5,6,7,8,9,10 , Norte (Amazônia Ocidental) 11 e Nordeste (Pernambuco, Paraí-ba, Bahia, Ceará e Sergipe) 12,13,14,15,16,17,18 do Brasil.…”

“…Cerca de cinco a dez milhões de crianças por ano apresentam deficiência subclínica; 250 milhões apresentam sinais clínicos e bioquímicos, sendo mais gravemente atingidas, com registros de 250 mil a 500 mil novos casos de cegueira por ano 1 . O Brasil não dispõe de um inquérito em nível nacional sobre a prevalência da DVA, porém foram realizadas várias pesquisas nos últimos quarenta anos que utilizaram indicadores clínicos, bioquímicos e/ou dietéticos, cujos resultados estão agrupados e comentados em trabalhos de revisão sobre a situação da DVA no país [2][3][4][5][6][7] . Segundo publicação recente intitulada "Carências de Micronutrientes" 8 a DVA é problema de saúde pública no Brasil, um dos países mais afetados na América, atingindo principalmente as crianças em idade pré-escolar.…”
