Is Vitamin A Supplementation Associated With Anemia in Children Under 5 Years of Age in Peru: Secondary Analysis of the “Demographic Health Survey” 2015-2018?Ribaudo, Isabella, Aramburú-Duclos, Camila B., Blitchtein, Dora 01 January 2021 (has links)
Vitamin A deficiency (VAD) affects 12% of Peruvians under 5 years of age. Recent studies have shown an association with hematopoiesis and iron metabolism. In Peru, 3-quarters of a million children have anemia. We aimed to identify an association between Vitamin A supplementation (VAS) and anemia in children under 5 years of age. A cross-sectional secondary analytical study from the Peruvian Demographic Survey and Family Health (DHS) was conducted. The primary outcome, anemia, was measured through hemoglobin concentration and adjusted by altitude. The DHS interviewer ensured the participant’s VAS in the last 6 months through a structural healthcare card. The association was statistically significant using crude regression but disappeared when adjusted per socioeconomic level and gender. VAS was not significantly associated with a lower prevalence of anemia. Further studies are required to help identify the association between VAS and anemia. / Revisión por pares

The association between black tea consumption and iron status of African women in the North West Province : THUSA study / L. MullerMuller, Lizanne January 2005 (has links)
Motivation: A variety of factors including food shortage, poor hygiene and low
education levels affects the nutritional status of black women. Women also have a
high risk for the development of iron deficiency because they lose iron through
menstruation, the birth process and a low intake of iron containing foods. All of these
factors contribute to an increased risk for the development of iron deficiency anaemia
in women.
Objectives: The primary purpose of the study was to investigate the association
between tea consumption and iron status of African females in the North West
Province. To reach this purpose the specific aims were to (1) assess the iron status
of women, (2) determine tea intake, and (3) determine the relationship between tea
consumption and iron status, taking into account inhibiting and enhancing factors of
iron absorption.
Methods: A cross-sectional sample of apparently healthy females was taken from
five different strata of urbanisation. The subjects were then further divided into two
groups, namely younger women (younger than 45.9 years) and older women (older
than 46 years). A sample of 920 subjects was used. Data were obtained from
dietary, demographic and additional questionnaires, as well as from the taking of
blood samples. This study was a sub-study of the THUSA study.
Results: A total of 920 subjects participated of which 69.24% were younger women
and 30.76% were older women. Due to missing data, the number of subjects for
each parameter differed. The mean serum ferritin as well as haemoglobin
concentrations were within normal ranges for both groups. The mean dietary iron
intake for both groups was below recommendations. No significant correlations were
found between serum ferritin or haemoglobin and total tea intake as well as a variety
of other dietary factors. The low haemoglobin concentration group of the younger
and older women combined had a slightly higher intake of animal protein and
ascorbic acid than the high haemoglobin concentration group. On the other hand,
the high serum ferritin concentration group had a significantly higher intake of animal
protein than the low serum ferritin concentration group.
Conclusion: The results of this study indicated that tea does not have an inhibitory
effect on the iron status of the female population of the North West Province.
However, the investigation of other studies conducted on the same topic had mixed
results. Two of seven studies investigated and this study indicated that tea had no
inhibitory effect on iron absorption. These two studies, as well as this study were not
done in a controlled environment where certain factors can be controlled for, for
example, time of tea intake and milk consumption with tea. The other five studies
were, however, conducted in an environment where subjects were given test meals,
time of tea consumption was regulated and milk consumption with tea was recorded.
The conclusion can, therefore, be made that further studies on the South African
population in a controlled environment are necessary to give accurate
recommendations to the population. / Thesis (M.Sc. (Dietetics))--North-West University, Potchefstroom Campus, 2005.

Iron Deficiency and Iron Deficiency Anemia: Implications and Impact in Pregnancy, Fetal Development, and Early Childhood ParametersMeans, Robert T. 01 February 2020 (has links)
A normal pregnancy consumes 500–800 mg of iron from the mother. Premenopausal women have a high incidence of marginal iron stores or iron deficiency (ID), with or without anemia, particularly in the less developed world. Although pregnancy is associated with a “physiologic” anemia largely related to maternal volume expansion; it is paradoxically associated with an increase in erythrocyte production and erythrocyte mass/kg. ID is a limiting factor for this erythrocyte mass expansion and can contribute to adverse pregnancy outcomes. This review summarizes erythrocyte and iron balance observed in pregnancy; its implications and impact on mother and child; and provides an overview of approaches to the recognition of ID in pregnancy and its management, including clinically relevant questions for further investigation.

Prevalence of anaemia, deficiencies of iron and vitamin A and their determinants in rural women and young children: a cross-sectional study in Kalale district of northern BeninAlaofe, Halimatou, Burney, Jennifer, Naylor, Rosamond, Taren, Douglas 25 January 2017 (has links)
Objective: To identify the magnitude of anaemia and deficiencies of Fe (ID) and vitamin A (VAD) and their associated factors among rural women and children. Design: Cross-sectional, comprising a household, health and nutrition survey and determination of Hb, biochemical (serum concentrations of ferritin, retinol, C-reactive protein and alpha(1)-acid glycoprotein) and anthropometric parameters. Multivariate logistic regression examined associations of various factors with anaemia and micronutrient deficiencies. Setting: Kalale district, northern Benin. Subjects: Mother-child pairs (n 767): non-pregnant women of reproductive age (15-49 years) and children 6-59 months old. Results: In women, the overall prevalence of anaemia, ID, Fe-deficiency anaemia (IDA) and VAD was 47.7, 18.3, 11.3 and 17.7%, respectively. A similar pattern for anaemia (82.4 %), ID (23.6%) and IDA (21.2%) was observed among children, while VAD was greater at 33. 6%. Greater risk of anaemia, ID and VAD was found for low maternal education, maternal farming activity, maternal health status, low food diversity, lack of fruits and vegetables consumption, low protein foods consumption, high infection, anthropometric deficits, large family size, poor sanitary conditions and low socio-economic status. Strong differences were also observed by ethnicity, women's group participation and source of information. Finally, age had a significant effect in children, with those aged 6-23 months having the highest risk for anaemia and those aged 12-23 months at risk for ID and IDA. Conclusions: Anaemia, ID and VAD were high among rural women and their children in northern Benin, although ID accounted for a small proportion of anaemia. Multicentre studies in various parts of the country are needed to substantiate the present results, so that appropriate and beneficial strategies for micronutrient supplementation and interventions to improve food diversity and quality can be planned.

Transcriptomic and Cell-Specific Translatomic Aanalysis in Early Iron Deficiency Response in ArabidopsisRuijie Han (7046801) 13 August 2019 (has links)
<p>Iron is
an essential micronutrient for plant growth, development and productivity.
Although it is abundant in soil, the bio-availability of iron is often low for
plants in many areas of the world. The insufficient quantity of usable iron in
plants causes reduction in chlorophyll synthesis, reduced photosynthesis rate
and decreased growth and yield. Two major strategies, Strategy I and II, have
been discovered to be involved in response to low iron and a complex network of
biochemical and molecular pathways participate in the processes. </p>
<p> </p>
<p>Cellular
transcriptional regulation is associated with iron deficiency responses.
Multiple genes and pathways involved in iron-deficiency responses have been
identified in plants in the past decade. Here, we measured different
physiological parameters and used RNA-Seq to elucidate the physiological and
molecular responses in early stage of iron deficiency in the whole leaf of
model plant species Arabidopsis thaliana. In this study, Arabidopsis showed
reduced chlorophyll content, increased ferric reductase activity and reduced
antioxidant enzyme activities when stressed by iron deficiency. In addition, we
have identified multiple pathways that may play promising roles in the response
to iron deficiency, e.g., 1) we found that the auxin biosynthesis under iron
deficiency is preferentially depended on the TAA-YUC pathway rather than the
CYP79 pathways; 2) TCA cycle is involved in mediating the acclimation process
to the stress condition; 3) glucosinolate synthesis could be a limiting factor
for iron deficiency response due to its negative relationship with hormone and
energy metabolism.</p>
<p> </p>
Systemic
signals generated from leaves are critical for triggering iron deficiency
responses in roots. Due to the physiological characteristic and cellular
ultrastructure of companion cells (CCs), we hypothesize that the CCs located in
phloem play essential roles in regulating systemic nutrient signaling. In this
study, by using a cell-specific TRAP-Seq, we discovered that not only CCs
respond more drastically than the other cells in leaf, the altered molecular
pathways in the CCs are also more diverse during early iron deficiency
response. In particular, we found that auxin and sucrose transport and
metabolism in the CCs may be two of the key regulatory processes that plants
use to exert the shoot-to-root signaling process. Our discoveries have
collectively suggested that CCs may function as the central machinery in the
systemic signaling in response to iron deficiency. A comparison between whole
leaf transcriptome and translatome also suggested that translatomic analysis is
a more sensitive method for gene profiling than conventional transcriptomic
analysis.

O uso de suplemento a base de ferro e os níveis de hemoglobina identificados durante o período gravídico-puerperal / The supplement use the base of iron and the identified levels of hemoglobina during the gravídico-puerperal period.Carmo, Lilian Sheila de Melo Pereira do 08 November 2007 (has links)
O uso de suplemento a base de ferro é fundamental para profilaxia e tratamento da anemia ferropriva, agravo freqüente em gestantes que vivem em paises em desenvolvimento, e que se não for tratada, pode ter conseqüências tanto para mulher quanto para o feto. Entretanto, muitas mulheres não aderem a terapêutica. O objetivo deste estudo foi identificar a utilização de suplemento à base de ferro no ciclo grávido-puerperal, em um grupo de mulheres.Trata-se de um estudo descritivo com abordagem quantiqualitativa realizado em uma Unidade Básica e Distrital de Saúde (UBDS) de Ribeirão Preto, e que teve como sujeitos um grupo de mulheres, usuárias de um serviço de saúde, que compareceram a UBDS para consulta de puericultura. A coleta foi realizada através de entrevista, coleta de sangue para dosagem de hemoglobina e consulta aos prontuários. A idade das mulheres variou entre 19 a 24 anos, sendo que destas 36,3% apresentaram ensino fundamental incompleto e 75% referiu não trabalhar. Quanto a realização de pré-natal, 75% realizou em Centro ou Posto de Saúde tendo como média de consultas durante a gestação oito. Durante a gestação e o puerpério o valor médio de hemoglobina encontrado nas entrevistadas foi de 12,1 g/dl e 12 g/dl, respectivamente. Quanto ao uso de suplemento a base de ferro na gestação e puerpério, 81,8% referiu ter usado durante a gestação e 66,9% no puerpério. Assim, conseguimos identificar que a maioria das gestantes fez uso do suplemento durante a gestação e puerpério e que apresentaram hemoglobina maior que 11 g/dl, ou seja, não apresentavam anemia. Os dados qualitativos revelam que as mulheres desconhecem a importância do uso do suplemento neste período, sendo mais evidente a preocupação com a saúde do feto. / The supplement use the iron base is basic for Prophylaxis and treatment of the ferropriva anemia, I aggravate frequent in gestantes that live in paises in development, and that if it will not be treated, it can in such a way have consequences for woman how much for the embryo. However, many women do not adhere the therapeutical one. The objective of this study was to identify the use of supplement to the base of iron in the pregnant-puerperal cycle, in a group of mulheres.Trata-if of a descriptive study with carried through quantiqualitativa boarding in a Basic and District Unit of Saúde (UBDS) of Ribeirão Preto, and that a group of women had as citizens, users of a health service, who had appeared the UBDS for puericultura consultation. The collection was carried through through interview, collection of blood for dosage of hemoglobina and consults to handbooks. The age of the women varied enters the 19 24 years, being that of these 36.3% had presented incomplete basic education and 75% related not to work. How much the accomplishment of prenatal, 75% carried through in Center or Rank of Health having as average of consultations during gestation eight. During the gestation and the puerpério the average value of hemoglobina found in the interviewed ones was of 12,1 g/dl and 12 g/dl, respectively. How much to the supplement use the base of iron in the gestation and puerpério, 81.8% related to have used during gestation and 66.9% in the puerpério. Thus, we obtain to identify that the majority of the gestantes made use the supplement during the gestation and puerpério and that they had presented 11 bigger hemoglobina that g/dl, or either, they did not present anemia. The qualitative data disclose that the women are unaware of the importance of the use of the supplement in this period, being more evident the concern with the health of the embryo.

Anemia e alimentação no primeiro ano de vida / Anemia and nutrition in the first year of lifeSouza, Sonia Buongermino de 26 August 1994 (has links)
o presente trabalho teve por objetivo verificar a possível associação entre alimentação no primeiro ano de vida e anemia ferropriva. Estudou-se uma amostra de 317 crianças com até 12 meses de idade, matriculadas e freqüentando quatro Centros de Saúde Escola do município de São Paulo. As informações sobre a alimentação foram obtidas pelo método de inquérito recordatório, em entrevista com as mães das crianças, na ocasião da consulta ou da vacinação. A presença de anemia foi verificada pela concentração de hemoglobina, determinada pelo método da cianometahemoglobina. Utilizou-se o critério recomendado pela Organização Mundial de Saúde (OMS) para diagnóstico da anemia, verificando-se a prevalência de 14,5 por cento entre toda a população e 22,4 por cento entre as crianças maiores de 180 dias. As associações entre anemia e duração do aleitamento materno exclusivo, idade de introdução de alimentos não lácteos e freqüência de consumo de alimentos fontes de ferro e/ou potenciadores da sua absorção não foram significantes. A ausência do aleitamento materno, até pelo menos 4 meses, associou-se à anemia. Nessa faixa etária encontraram-se 26,9 por cento de anêmicas entre as crianças que tomavam outros leites e 8,6 por cento entre as que só recebiam leite materno. A anemia não se associou às variáveis sócioeconômicas estudadas: escolaridade do pai, da mãe e renda familiar. / This study was made to find out the possible association between the diet in the first year of life and iron deficiency anemia. A sample of 317 infants aged 0-12 months was studied in four school health centers in the city of São Paulo. The informations about diet were obtained by the recordatory survey method, in interviews with the infant\'s mothers. The presence of anemia was verified by hemoglobin concentration, using the cianometahemoglobin method. The criteria recommended by the World Health Organization (WHO) was utilized for the diagnostic of anemia. The prevalence of 14,5 per cent was found in all the population and 22,4 per cent in infants aged more than 180 days. The associations between anemia and time of exclusively breast-feeding, and age of introduction of other foods and/or eating foods which enhance iron absorption were not significants. The absence of breast-feeding, until at least 4 months, were associated with anemia. In this age were found 26,9 per cent of anemics among infants receiving others milks and 8,6 per cent among those receiving only breast milk. Anemia was not associated with socioeconomic variables: parents education levels and familiar income.
