Abstract
Zinc deficiency may affect pregnancy outcome. In order to carry out longitudinal studies of zinc status in Chilean population of lew incomes groups, we evaluated 124 pregnant teenagers at the begining the prospective follow-up. They were 16.3±1.4 years old (12-18), beginning health controls at 12.6±3.7 weeks (7-20); nutritional status showed 28% of inadequate weight for heifht and gestarional age. Dietary history records revealed daily intakes of : Zn 6.8 ±2.7 mg,. or 0.81 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/dl).
We conclude that Chilean pregnant teenagers of low income groups present a higer prevalence of low zinc intake that those of other nutrients, not associate to low plasma zinc.
