The influence of dietary intake on serum zinc in 44 pregnant women in the third trimester of pregnancy and 10 healthy controls were studied. For assessment of the dietary intake 5-d record were used. Zinc in serum was analysed by flame AAS. Dietary zinc intake below the RDA was recorded in both groups studied (pregnant and nonpregnant women). Serum zinc in 42.8% of the pregnant women was below the cut off value. Only 1 of the nonpregnant women was with low serum zinc. For comparing serum zinc of both groups odd ratio of 9.56 was calculated. Zinc in diet correlates significantly with the energy intake, protein and animal proteins in diet. Serum zinc correlates with animal protein intake and total energy of the diet. Pregnancy is a significant modulator of zinc status, but nutritional factor is a very important determinant for maintaining optimal nutritional zinc status.
