“…Mais recentemente, estudos de base populacional realizados nos estados de Pernambuco (Andrade, 2000), Sergipe (Martins, Santos & Assis, 2004) e na cidade de Teresina, PI (Paiva et al, 2006), revelaram prevalências igualmente elevadas de retinolemia inadequada em crianças na idade pré-escolar. Deve-se ainda ressaltar que estudos pontuais têm revelado prevalência elevada de DVA em outros grupos populacionais no estado de Pernambuco, a exemplo de escolares (Diniz et al, 2005), gestantes (Lopes et al, 2006) e idosos (Nascimento, 2005).…”

“…The Brazilian Ministry of Health estimates that the prevalence of gestational anaemia is 50 % (12) and it is associated with 20 % of total maternal deaths (17) . Some studies report that in communities where anaemia is prevalent among pregnant women, VAD should also be assessed (3,10,11) . A study performed in Recife, Brazil, revealed anaemia and VAD in 65·3 % and 25·0 % of postpartum adult and adolescent women, respectively (10) .…”

“…The WHO (5) considers VAD one of the aggravating factors for maternal mortality because it may be associated with worsening of hypertensive disorders of pregnancy due to the antioxidant role of vitamin A. In addition, VAD contributes to the worsening of puerperal infections because of the effects of vitamin A on the immune system and it is often associated with anaemia in pregnant women (6)(7)(8)(9)(10)(11) . Hypertension, haemorrhage and puerperal infection are among the main direct causes of maternal death among Brazilian women (12) .…”

Objective: To describe the prevalence and determinants of gestational night blindness in pregnant women receiving care in a hospital in Rio de Janeiro, Brazil. Design: Cross-sectional study of pregnant and postpartum women receiving care in a public hospital in Rio de Janeiro from 1999 to 2001 (group I; n 225) or from 2005 to 2008 (group II; n 381). Night blindness was identified through a standardized and validated interview (WHO, 1996). The determinants of gestational night blindness were identified through a hierarchical logistic regression model. Setting: Public maternity hospital in Rio de Janeiro, RJ, Brazil. Subjects: Adult pregnant and postpartum women (n 606), aged ≥20 years. Results: The prevalence of gestational night blindness was 9·9 %. The final model revealed that not living in the South Zone of Rio de Janeiro (distal level: adjusted OR = 1·846; 95 % CI 1·002, 3·401), belonging to group I (intermediate level: adjusted OR = 2·183; 95 % CI 1·066, 4·471) and for the proximal level, having a history of abortion (adjusted OR = 2·840; 95 % CI 1·134, 7·115) and having anaemia during the first and second trimesters of pregnancy (adjusted OR = 3·776; 95 % CI 1·579, 9·029) were determinants of gestational night blindness. Conclusion: Gestational night blindness should be assessed for during the prenatal care of all pregnant women, especially those living in deprived areas of the city and/or who have a history of abortion or anaemia. Nutritional monitoring is recommended during pregnancy to control gestational night blindness. Keywords Night blindness Vitamin A deficiencyPregnant women Cross-sectional study Vitamin A deficiency (VAD) remains an ongoing public health problem in many areas of the world. Children and women of childbearing age are most affected, with an estimated 190 million children of pre-school age and 19 million pregnant women having VAD (1) . Based on night blindness (XN; the ocular symptom of VAD) and xerophthalmia (the first stage of ocular manifestations due to VAD), it is estimated that 5·2 million pre-school children and 9·8 million pregnant women are impacted, corresponding to 0·9 % and 7·8 % of these populations worldwide (1,2) . A national survey conducted in Brazil examined VAD among children of pre-school age and women of reproductive age (3) . Analyses of serum retinol, which is the biochemical indicator of VAD, revealed that women from the Southeast region evinced the highest prevalence of VAD in the country (14·0 %), surpassing those in the Northeast region (12·1 %), which is considered at higher risk for this

The Effects of Two Maternal Vitamin A Supplementation Regimens on Serum Retinol in Postpartum Mothers: A Randomised Controlled Trial in Brazil

et al. 2012

Objective. To test whether the serum retinol level in mothers supplemented with 400,000 IU of vitamin A is higher than in those supplemented with 200,000 IU and to estimate duration of the protective effect of vitamin A supplementation in the serum retinol level. Methods. Double-blind, randomised controlled trial performed in two hospitals in the state of Pernambuco in northeast Brazil. Three hundred twelve mothers were recruited immediately postpartum. All women received a capsule containing 200,000 IU of vitamin A, and 10 days after delivery, they were randomly assigned to one of two treatment groups. One group received a second capsule containing vitamin A and the other group received a placebo. Each group was invited back after 2, 4, and 6 months for serum retinol analyses. Results. No difference was found between the two groups in serum maternal retinol concentration at 2 months (2.13 versus 2.03 μmol/L), 4 months (2.20 versus 2.24 μmol/L) or 6 months (2.29 versus 2.31 μmol/L). Because there was no further effect and because this population has a level of vitamin A deficiency considered mild, our results do not support a proposal to increase the dosing schedule for vitamin A in postpartum women as recommended by the IVACG.
