Abstract:
The nutritional status, serum protein, albumin, calcium, zinc, iron, SF, FEP, vitamin A, activity of RBC transketolase, and blood glutathione redu-ctase of 349 normal primigravidas, 30 healthy non-pregnant women and 42 toxemic gravidas were estimated longitudinally from the 1st trimester to delivery. It was noted that serum protein, albumin, Ca, Zn, and Fe decreased markedly in the course of pregnancy. The content of serum vitamin A showed no variation or decrease in the 3rd trimester in 1/3 of the pregnant women observed. Insufficiency of thiamine and riboflavin were noted in 16.7% and 47% of the normal pregnant women respectively. The adequate nutrients intakes in pregnancy were considered to be: Energy, +200 kcal/d; Protein, + 15g/d in the 2nd trimester and +25g/d in the 3rd trimester; Calcium 1000 mg/d in the 2nd trimester and 1500mg/d in the 3rd trimester; Zinc, 20mg/d; Iron 26 or 30 mg/d by supplementation if possible; vitaminA 1000 ?gRE/d; both thiamine and riboflavin 1.8 mg/d.
