“…Of all, 29% had moderate and severe anemia. The prevalence of anemia was higher than that reported in other studies conducted in Northeast Brazil, 12,17,24 other Brazilian regions, 7,10 and also other developing countries, 1 probably due to the fact that the children studied at these daycare centers were younger and came from the poorest families. Also, the cut-off point of 110 g/L is probably too high for infants, thus overestimating the prevalence of anemia in this age group.…”

“…In the present study, although a signifi cant association between CRP with serum ferritin concentration was found, the latter may be underestimated, possibly due to its lower sensitivity as a specifi c marker of iron defi ciency in infants. 10,24 Chronic or recurrent infectious diseases such as malaria and diarrheal diseases can interfere with iron intake, absorption and metabolism. Although diarrhea has declined in Brazil, this reduction has been less pronounced in the Northeastern region.…”

OBJECTIVE:To diagnose iron defi ciency anemia in children. METHODS:The study was conducted with a sample of 301 children aged six to 30 months attending public daycare centers in the city of Recife, Northeast Brazil, in 2004. The diagnoses of anemia were based on a combination of different hematological and biochemical parameters: hemoglobin, mean corpuscular volume, ferritin, C-reactive protein, transferrin saturation and transferrin receptor. The chi-square test and ANOVA were used in the statistical analysis. RESULTS:Of all children studied, 92.4% had anemia (Hb <110 g/L) and 28.9% had moderate/severe anemia (Hb <90 g/L). Lower levels of hemoglobin were found in children aged 6-17 months. Iron defi ciency was found in 51.5% of children using ferritin (<12 μg/L) as parameter. Taking into consideration the combination of hemoglobin level, ferritin and transferrin receptor, 58.1% had anemia with iron defi ciency, 34.2% had anemia without iron defi ciency and 2.3% had iron defi ciency without anemia. Mean ferritin concentration was signifi cantly higher in children with high C-reactive protein when compared with those with normal levels (22.1 vs. 14.8 μg/L). CONCLUSIONS:The use of several biochemical and hematological parameters allowed to diagnosing iron defi ciency anemia in two thirds of children, suggesting a need to identify other determinants of anemia without iron defi ciency.

“…Apesar dos coeficientes de correlação demonstrados por este estudo serem baixos, a correlação obtida entre a idade e níveis de ferro (19%), ferritina (12%) e hemoglobina (14%) podem corroborar com os dados do estudo de Vieira et al (2007), que demonstraram correlação positiva de hemoglobina e ferritina com a idade das crianças avaliadas (7).…”

Iron deficiency anemia may impair learning ability in children aged 02 to 06 years. This disease may produce behavioral effects such as lack of attention, fatigue and tiredness that can lead to poor school performance. The aim of this study was to determine the number of children 02 to 06 years who performed the measurements of ferritin, serum iron and hemogram in a clinical laboratory in Belo Horizonte/MG, in the first half 2011, seeking to evaluate the results of these examinations and to establish the prevalence of iron deficiency in studied subjects. We conducted a descriptive cross-sectional observational study. Through software-BI SADIG, used for data management of the clinical laboratory, we selected 363 children from 02 to 06 years who performed the measurements of ferritin, serum iron and hemogram during the period from January first to July thirty-one, two thousand and eleven. The male children had plasma ferritin levels significantly lower when compared with female children (p<0.05). There were no significant differences between participants of both sexes for serum iron and hemoglobin. Nine children (2.5%) had anemia (Hb ≤ 11.0 g/dL and ferritin ≤ 12 ng/mL). There was a low prevalence of iron deficiency anemia in children. The most important finding of this study was nearly five times greater risk of developing iron deficiency anemia in children who had plasma ferritin levels below or equal to 12 ng/mL, suggesting that this may be considered the best cutoff point for the population studied.KEY WORDS: iron deficiency anemia; children; ferritin. RESUMOEm crianças pré-escolares a anemia ferropriva pode comprometer a capacidade de aprendizagem, além de produzir efeitos comportamentais como a falta de atenção, fadiga e cansaço que podem levar ao baixo rendimento escolar. O objetivo deste estudo foi verificar o número de crianças de 02 a 06 anos que realizaram as dosagens de ferritina, ferro sérico e hemograma, com suspeita de anemia ferropriva, num laboratório clínico, no primeiro semestre de 2011, buscando avaliar os resultados dos referidos exames e estabelecer a prevalência de anemia ferropriva nos indivíduos estudados. Foi conduzido um estudo observacional descritivo do tipo transversal. Através do software SADIG-BI, utilizado para gerenciamento de dados, foram selecionadas 363 crianças de 02 a 06 anos que realizaram os exames ferritina, ferro sérico e hemograma no período de 01/01/2011 a 31/07/2011. As crianças do sexo masculino apresentaram níveis plasmáticos de ferritina significativamente mais baixos quando comparadas com as crianças do sexo feminino (p<0,05). Com relação aos parâmetros ferro sérico e hemoglobina, não foram observadas diferenças significativas entre os participantes dos dois sexos. Das 363 crianças estudadas, 9 (2,5%) apresentavam anemia ferropriva (Hb ≤11,0 g/dL e Ferritina ≤12 ng/mL). Foi observada uma baixa prevalência de anemia ferropriva nas crianças estudadas. O achado mais importante deste estudo foi o risco quase cinco vezes maior do desenvolvimento de anemia ferrop...

“…3,9,10,19,24 This greater vulnerability might be attributed, mainly, to the accelerated growth and consequent increase in the iron needs in the fi rst years of life. 9 After the sixth month of age, with the end of the iron reserves that were acquired in the uterus, nutrition becomes fundamental to supply the mineral.…”

OBJECTIVE:To estimate the magnitude of the anemia, to analyze the time trends and investigate the factors associated with this disturbance in children in the state of Paraíba, Brazil. METHODS:A cross-sectional survey, of population-based, with 1108 children, aged 6 to 59 months, both sexes in the state of Paraíba. Hemoglobin (Hb) in venous blood was analyzed with an automatic counter. The social-economic and demographic characteristics of children were obtained by questionnaire. Proportions were compared by Pearson's chi-squared test, and the association between hemoglobin concentrations and potential risk factors was tested by regression model Poisson. The time trend of anemia was assessed by the increase/decreased in the prevalence of anemia, using as comparison the prevalence observed in the years 1982, 1992 and 2007. RESULTS:The prevalence of anemia (Hb < 11.0 g/dl) in the state of Paraíba was 36.5% (95%CI 33.7 to 39.3). It was observed that 1.3% (95%CI 0.7 to 1.8) were in severe form (Hb < 7.0 g/dl), 11% (95%CI 9.4 to 13.5) in a moderate form and 87.6% (95%CI 79.1 to 91.2) in the mild form. There was an increase 88.5% in cases of anemia between the years 1982-1992 and stabilization in the prevalence between the years 1992-2007. The analysis adjusted Poisson model showed a greater susceptibility to anemia in children 6 to 24 months of age, those breastfed for six months or more, who co-inhabited with more than four people in the same household and lived in houses with less than fi ve rooms. CONCLUSIONS:The results revealed that anemia remains an important public health problem in the state of Paraíba and despite having been shown an stabilization in the prevalence of anemia between 1992-2007, differently the prevalence observed between 1982-1992, this defi ciency presents in high level, witch requires more effective measures of prevention and control.
