“…The prevalence resulted high (one quarter of children 111 years of age). A study in Vietnamese rural children aged 68 years showed a prevalence of magnesium LSC of 59.5%, 39 higher than in this sample.…”

Objective. To describe the micronutrient nutritional status of a national sample of 1-11 year old Mexican children surveyed in 2006 in National Health and Nutrition Survey (ENSANUT 2006) and their association with dietary and sociodemographic factors. Materials and methods. Serum samples were used (n=5 060) to measure the concentrations of ferritin, transferrin receptor, zinc, copper and magnesium. Results. Prevalence of deficiencies in 1-4 and 5-11y old children were for iron (using low ferritin) 26.0 and 13.0%; zinc, 28.1 and 25.8%, respectively; and copper, ≈30% in both age groups. Magnesium low serum concentrations (MLSC), were found in 12.0% and 28.4% of the children, respectively. Being beneficiary of Liconsa (OR=0.32; C.I.95%, 0.17-0.61) or belonging to higher socioeconomic status (OR=0.63; C.I.95%, 0.41-0.97) were protective against iron deficiency. Increasing age (OR=0.59; C.I.95%, 1.19-1.32) and living in the Central Region (OR=0.59; C.I.95%, 0.36-0.97) were protective against MLSC. Conclusions. Deficiencies of iron and zinc are serious public health problems in Mexican children. ResumenObjetivo. Describir el estado nutricio de micronutrimentos en niños de 1-11 años de edad de la Encuesta Nacional de Salud y Nutrición 2006 y su asociación con factores dietéticos y sociodemográficos. Material y métodos. Se usaron muestras séricas (n=5 060) para medir las concentraciones de ferritina, receptor de transferrina, zinc, cobre y magnesio. Resultados. La prevalencias de deficiencias en niños de 1-4 y de 5 a 11 años fueron para ferritina, 26.0 y 13%; zinc, 28.1 y 25.8% respectivamente y cobre ≈30% en ambos grupos. Las concentraciones bajas de magnesio (CBM) fueron 12.0 y 28.4%, respectivamente. Ser beneficiario de Liconsa (RM=0.32; IC 95%: 0.17-0.61) y pertenecer al nivel socioeconómico alto (RM=0.63; IC, 95%: 0.41-0.97) fueron protectores para deficiencia de hierro. La edad (RM=1.26; IC, 95%: 1.19-1.32) y vivir en la región Centro (RM=0.59; IC, 95%: 0.36-0.97) fueron protectores para CBM. Conclusiones. Las deficiencias de hierro y zinc son serios problemas de salud pública en niños mexicanos.

“…Se deficiency may contribute to cardiovascular disease, anemia [11], and immune dysfunction, all of them are common in patients with renal failure [12]. The reason for Se depletion in ESRD patients is not clear and several of the following factors should be taken into account to explain this phenomenon: decreased dietary intake combined with protein restrictions, impaired gastrointestinal absorption of Se compounds and HD treatment [4,13].…”

In this cross-sectional study, selenium (Se) levels in the sera of 35 hemodialysis (HD) patients and 34 patients undergoing continuous ambulatory peritoneal dialysis (CAPD) for more than 3 months were compared with the serum Se levels of 34 healthy volunteers. The observed Se levels of 100.8 ± 51.9 µg/L in the sera of the HD patients and of 65.5 ± 32.1 µg/L in the sera of the CAPD patients were significantly lower than the 134.9 ± 81.2 µg/L of the controls, with p = 0.002 and 0.02, respectively. Furthermore, the Se levels were significantly higher in the HD rather than the CAPD patients (p = 0.01). In the spent dialysate effluent fluid of 32 of the CAPD patients Se was undetectable, in the remaining two CAPD patients the Se levels were 1.9 and 4.6μg/l, respectively. The low Se levels of HD and CAPD patients as compared to healthy persons are attributed to diminished Se retention due to chronic oxidative stress.

“…The prevalence of anemia ranges from 25 to 55.6%, depending on the study area and population [6,7,8,9,10,11,12,13]. In pregnant women, a prevalence of anemia of 40-50% has been reported [7,9].…”

Burden of Anemia in Relation to Thalassemia and Iron Deficiency among Vietnamese Pregnant Women

et al. 2013

View full text Add to dashboard Cite

Background and Aims: Information about the extent to which anemia is related to thalassemia and iron deficiency (ID) is not available in Vietnam. This study investigated the burden of anemia in relation to thalassemia and ID among Vietnamese pregnant women. Methods: A cross-sectional study was conducted in Thua Thien Hue, Central Vietnam. Blood samples taken from 399 pregnant women with a gestational age <12 weeks were analyzed. Anemia was defined as Hb levels <11 g/dl, and ID as ferritin values <15 ng/ml. Results: Out of 399 participants, 77 (19.3%) were anemic. While the prevalence of ID was 20.1%, the prevalence of ID anemia was 6.0%. The overall prevalence of thalassemia was 7.3%. Of the 77 anemic women, 24 (31.2%) had ID, and 20 (26.0%) had thalassemia genes. The rest (42.9%) were anemic due to unknown causes. Conclusions: The results indicate that ID remains a significant health burden among the study population, together with anemia caused by unknown factors. Thalassemias appear not to contribute to a great extent to anemia among Vietnamese pregnant women. Other causes need to be investigated further in order to develop an effective control program for anemia within the population.
