The samples in the pregnant women were collected in the first, second and third trimesters of pregnancy. The socio-economic condition was proved to be important when comparing both groups of pregnant women. Such differences had already been remarked in the non-pregnant women group where the serum concentration was statistically greater at a higher socio-economic condition. Also both groups had different behaviours during the pregnancy. The women having a high socio-economic condition did not present any remarkable difference during the pregnancy whereas the low socio-economic condition ones, showed in the third trimester, zinc levels significantly lower than in the second trimester of pregnancy. © Gordon and Breach Science Publishers, Inc., 198435-43engArtigo10.1080/03004438401501052-s2.0-84947675095
