Nd. Nogueira et al., Utilization of iron at different concentrations on pregnant teenagers alsosupplemented with zinc and folate, ARCH LAT NU, 51(3), 2001, pp. 225-229
The pregnant teenager is considered at nutritional risk specially due to th
e fact that most of them still growing and developing. Therefore the demand
s of pregnancy compete with those of growth causing an extra need for her a
nd the fetus (1). Iron, zinc and folate are essential nutrients that are fr
equently low on the teenagers diet. Besides that there is not much specific
information available about these nutrient recommendations and their inter
action among each other. The data available is limited and demands more inv
estigation. This study was conducted at a Public Maternity Hospital located
at Teresina, Piaui, Brazil. The main objective of this study was to invest
igate the effect of different concentrations of iron supplementation (80 an
d 120 mg of ferrous sulfate) together with folate (250 mug) and zinc (5 mg)
on the hemoglobin concentration and iron stores (plasma ferritin) of pregn
ant adolescents. The supplementation was done from the 16(th) to 20(th), we
eks of gestation until delivery. The data founded proved that either 80 mg
or 120 mg of iron supplements had similar effect on the improvement of hemo
globin concentration although results showed no statistical significance.
