DURAN F, Eliana; SOTO A, Delia; LABRANA T, Ana María  y  PRADENAS P, Francisco. DIETETIC ADEQUATION OF MICRONUTRIENTS IN PREGNANT WOMEN. Rev. chil. nutr. [online]. 2007, vol.34, n.4, pp. 321-329. ISSN 0717-7518.  http://dx.doi.org/10.4067/S0717-75182007000400005.

In order to identify the contribution of micronutrients to the diet during pregnancy, a 24 hours-recall survey in two non-consecutive days was applied to 241 pregnant women in 1996. Their ages were 20 to 43 years, without associated pathology, attending 8 urban health centers of the city of Concepción. The contributions of vitamin B1, B2, C, niacin, folate, zinc, calcium, iron, potassium, selenium, phosphorus, sodium and energy were calculated. Data was expressed as means, median and percentiles, and the differences between the recommendations and calculated intake were done by the Student t-test with a significance of p<0.05. For requirements of daily energy and the recommendations for vitamins and minerals the FAO/OMS/UNU 2001 and the Dietary Reference Intakes (DRIs) 2001 were used, respectively. The overall results showed an adequacy of less than 75 % of recommendations in 86.7 % of pregnant women for niacin, 95.2 % for folic acid, 55.6 % for zinc, 54.7 % for calcium, 62.6 % for iron and 60.9 % for potassium, respectively. The results show that some specific micronutrients are not covered by the diet, a reason why supplementation becomes necessary from pre-gestational age
