Iron and infection. LBW was defined as birthweight below 2, g. The analysis of growth for the weigh-for-age and height-for-age indicators was based on NationalCenter for HealthSstatiscs standards. For anemia diagnosis, a biochemical hemoglobin concentration dosage, using HemoCue direct colorimetric method was employed.
Undernutrition, as indicated by the height-for-age indicator, was high especially for children aged months with LBW. Keywords: Anemia. Infant, low birth weight. Protein-energy malnutrition. Height weight. The deleterious consequences of LBW for infant survival have been exhaustively described. If minimizing the risk of LBW is the responsibility of antenatal care, it is up to well-baby care to give LBW children special attention so as to promote their complete recovery, leveling them with term infants of adequate birthweight.
Growth is a process subject to rapid alteration during infancy, and is affected by several factors such as gender, length at birth, and genetic potential. Growth evaluation is used for the definition of health and nutritional status because health disturbances, regardless of their etiology, invariably affect child growth Onis and Habitch,11 Iron deficiency has deleterious consequences on health, reducing physical capacity, and having a negative influence on the ability to work, both at individual and community levels.
According to Lonnerdal and Dewey6 , babies up to age four months have a high concentration of circulating hemoglobin, iron being obtained through the destruction of erythrocytes and reused for the synthesis of new hemoglobin, thus reducing the need for exogenous iron.
In addition, up to this stage, children have a sizeable iron reserve in the liver. Between ages 12 and 24 months, there is a reduction of the prevalence of anemia due to reductions in growth rate Olivares et al,8 Iron-deficiency anemia diagnoses based on hemoglobin concentration levels, even without any additional biochemical exams, are considered to be adequate for populations in which iron deficiency is highly prevalent. Data were collected at Health Units of the Secretariat of Health, which are distributed throughout the entire municipality so as to facilitate access to health services by the population.
Activities developed at these facilities include physician, nurse, and dentist appointments directed towards children, pregnant women, and adults. Studied population comprised all single-born children under one year seen at these facilities during a five-workday period. Data collection was carried out between March and July , and led to a total sample of children. Interviews with the mothers who accompanied their were conducted by trained interviewers. Child nutritional status was classified using the Z-score classification system.
Seven mothers 1. For the diagnosis of anemia, a biochemical hemoglobin concentration dosage [Hb] was employed. A comparison was made between observed [Hb] and estimated [Hb] in order to verify the influence of growth on hemoglobin concentration. Such an influence can be analyzed through theoretical calculations of hemoglobin concentration considering the amount of iron provided by feeding in relation to the endogenous amount existent at birth.
A database was built using Dbase III software including all coded variables. The data were analyzed with Epi-Info software. In order to analyze the relationship between studied variables and LBW, chi-squared association tests with Yates correction, Mantel-Haenzel adjusted analysis, and Pearson correlation for linear trend measurements between quantitative variables were performed.
Four blood tests 0. In this study, however, we observed that, in spite of the weight gain among adolescents being smaller, and the respective reductions after labor greater, no relationship was observed between the child and maternal anemia.
Of all mothers studied, 87 Mean hemoglobin concentration for the groups studied was 9. The concentration observed for the whole study was This is due to the estimated [Hb] for babies up to age four months being higher than the observed [Hb]. In all three studied groups there was a low correlation between these variables, in opposition to what is generally reported in the literature. Among the entire study population, 2. Among preterm children, Along with malnutrition, anemia is a deficiency of extreme importance during pregnancy, due to its high prevalence and, especially, due to the harmful effects to which it is associated.
It is important to note that there are no standardized values for the identification of anemia during the first semester of life.
Values usually employed refer to selected children, whose diet, most of the time, includes iron-enriched food, a nutritional practice uncommon among children seen at public health facilities. Thus we adopted the A study of the evolution of hemoglobin concentration for both mothers and children shows that the former recover from pregnancy and puerperium quite rapidly. The average [Hb] of mothers two months after delivery is similar to that of non-pregnant women.
On the other hand, the children There is a large number of questions concerning the readiness of adolescents and the nutritional competition between them and their unborn children. This condition may lead to negative results for the child, including preterm birth or intra-uterine growth retardation and such children would suffer not only from alterations in growth, but in development as well.
It should be added that the children of teenage mothers may be at greater risk of developing anemia and other problems for the same reasons Silva et al,15 The amount of iron accumulated by the fetus during intrauterine life is proportional to the amount of weight it gains. Thus the lower the birthweight, the lower the amount of organic iron. This is confirmed in the present study: among LBW children, 29 According to DeMayer et al3 , during its first semester the infant uses up the iron reserves accumulated during intrauterine life in order to satisfy its needs.
