Abstract
Zinc deficiency may affect pregnancy outcome. In order to begin study of zinc status in Chilean population of low income groups, we studied 124 pregnant teenagers on admission to their prenatal controls. They were 16.3 ± 1.4 years old (12-18), beginning pregnancy controls at 12.6 ± 3.7 weeks (7-20); nutritional status showed 28% deficit of weigth for height and gestational age. Dietary history records revealed daily intakes of: Zn 6.8 ± 2.7 mg, or 0.81 mg/MJ (42.5% of reccomendations); iron 18.3 ± 7.6 mg or 8.9 mg/1000 Kcal (60% of RDA) with 47.5% of animal origin; vegetal fiber 5.3 ± 2.8 g. Plasma zinc was 96.3 ± 13.7 ug/dl (15/126<80 ug/dl; Hb 13.0 ± 1.3) (4/116<11 g/d).
We conclude that Chilean pregnant teenagers of low income groups present a higher prevalence of low zinc intakes than of other nutrients, these low intakes are not associated to low plasma zinc.
