“…4,5 The mean (± SD) plasma vitamin A level of 27.7 (± 12.4) µg/dl in this study is similar to 31.8 (± 18.6) µg/dl reported by Ajaiyeoba 15 in pre-school age children in a nation-wide study in Nigeria, and 26.8 (±7.0) reported by Persson et al 4 in school age children in Bangladesh. This finding however differs from the report of Valencia et al 5 with lower mean of 21.6 (± 5.2) µg/dl. This difference in the mean plasma vitamin A level is also reflected in the prevalence of vitamin A deficiency which was higher in the report of Valencia et al 5 (46.3%) compared with 29.6% in this study.…”

“…A lower prevalence rate of anaemia 31% and 1.4% was reported by Persson et al 4 and Valencia et al 5 in school age children in Bangladesh and North west Mexico respectively. This difference may be attributed to the possible different aetiologic factors responsible for anaemia in the population studied.…”

“…This difference may be attributed to the possible different aetiologic factors responsible for anaemia in the population studied. The low prevalence of anaemia reported by Valencia et al 5 was associated with a low prevalence of iron deficiency (4.4%) which was attributed to the Yaqui Indian diet (corn tortillas, pinto beans, wheat flour tortillas), which is rich in energy, protein and iron. Although the diet of the population studied by Persson et al 4 was not evaluated in relation to anaemia, there was a comparative prevalence rate of anaemia (31%) and iron deficiency (30%).…”

“…12 These studies however, did not include school age children in which vitamin A deficiency have been reported in studies outside Nigeria. 4,5 An unpublished study carried out in Benin-city by Otobo showed a high correlation between vitamin A deficiency and anaemia. The study was however a hospital-based study among pre-school age children with malaria.…”

Both human immunodeficiency virus–infected and human immunodeficiency virus–exposed, uninfected children living in Brazil, Argentina, and Mexico have similar rates of low concentrations of retinol, β-carotene, and vitamin E

Our objective was to describe the prevalence of low concentrations of retinol, β-carotene, and vitamin E in a group of HIV-infected Latin American children and a comparison group of HIV-exposed, uninfected children. Our hypothesis was that the rates of low concentrations of these micronutrients would be higher in the HIV-infected group than those in the HIV-exposed, uninfected group. This was a cross-sectional substudy of a larger cohort study at clinical pediatric HIV centers in Latin America. Serum levels of micronutrients were measured in the first stored sample obtained after each child’s first birthday by high-performance liquid chromatography. Low concentrations of retinol, β-carotene and vitamin E were defined as serum levels below 0.70 μmol/L, 0.35 μmol/L and 18.0 μmol/L, respectively. The population for this analysis was 336 children (124 HIV-infected, 212 HIV-exposed, uninfected) aged ≥ 1 to < 4 years of age. Rates of low concentrations were 74% for retinol, 27% for β-carotene, and 89% for vitamin E. These rates were not affected by HIV status. Among the HIV-infected children those treated with antiretrovirals were less likely to have retinol deficiency, but no other HIV-related factors correlated with micronutrient low serum levels. Low concentrations of retinol, β-carotene and vitamin E are very common in children exposed to HIV living in Brazil, Argentina and Mexico, regardless of HIV-infection status.

An international perspective of the magnitude of anemia in indigenous peoples is currently lacking. The present systematic review was performed to characterize the global prevalence, severity, and etiology of anemia in indigenous peoples by conducting a systematic search of original research published in English from 1996 to February 2010 using PubMed, Medline, and Embase. A total of 50 studies, representing the following 13 countries, met the inclusion criteria: Australia, Brazil, Canada, Guatemala, India, Kenya, Malaysia, Mexico, New Zealand, Sri Lanka, Tanzania, the United States, and Venezuela. Results indicate major deficiencies in the coverage and quality of anemia monitoring data for indigenous populations worldwide. The burden of anemia is overwhelmingly higher among indigenous groups compared to the general population and represents a moderate (20-39.9%) to severe (≥40%) public health problem. For the most part, the etiology of anemia is preventable and includes inadequate diet, poor living conditions, and high infection rates (i.e., malaria and intestinal parasites). A concerted global effort is needed to reduce the worldwide burden of anemia in these marginalized populations.
