Resumo
Objective: To verify the prevalence of anemia, iron deficiency
anemia and iron deficiency in infants, at a Public Health Unit in the
city of Goiânia – Brazil; to analyze and to correlate the hematologic
and biochemical variables.
Methods: A cross-sectional study was carried out. One
hundred and ten full-term infants of the 120 mothers interviewed
were included. The infants aged between six and twelve months and
there were not twins. Socioeconomic and hematologic data was
obtained. Venous blood was taken from fasting infants in order to
carry out a complete hemogram through electronic cell counting,
serum iron, serum ferritin and C-reactive protein, which were used
in the evaluation of the etiology of iron deficiency in the anemic
infants. Children with hemoglobin < 11g/dL were considered ane mic.
Results: The prevalence of anemia was 60.9%. In the diagnosis
of the iron deficiency etiology in infants without an inflammation
process, when considering the alteration of hemoglobin plus two
more indices among mean corpuscular volume (MCV) or mean
corpuscular hemoglobin (MCH) or serum ferritin or serum iron, the
prevalence of the iron deficiency was 87%. Nevertheless, when red
cell distribution width (RDW) was included in the indices, the
prevalence was 97.8%. In the non-anemic infants, considering
ferritin and RDW, the prevalence of iron deficiency observed was
28%. The best correlation among hematologic and biochemical
variables were between hemoglobin and hematocrit (r = 0.946), and
MCH with MCV (r = 0.950).
Conclusions: The main etiology in infants was iron deficiency
anemia and its prevalence varied according to different parameters
and criteria.
