Zinc has been established to be essential for humans and act as an electron acceptor contributing to catalytic activity in many important enzymes. Zinc also plays a very important role in pregnancy. There is very few data in India on serum levels of micronutrients in pregnant women specially Zinc and its relation with serum Iron (Fe) levels. We decided to carry out this pilot study in order to provide the baseline data that may have public health implications and further guide us. This study was conducted in the hill region of Uttarakhand, India enrolling sixty (60) pregnant women, in the age group of 18–35 years with (20) twenty control cases to compare with standard serum levels. Blood Hemoglobin with serum iron and zinc levels was estimated. In the present study 48.3% of the pregnant women had hypozincemia and prevalence was higher in anaemic pregnant women (53.57%). Serum zinc levels are significantly lower in iron deficient anaemic pregnancy (IDAP), when compared to non-iron deficient anaemic pregnancy (NIDP) and in control cases. The fall in zinc level may be due to physiological response of the maternal blood volume expansion though the role of iron supplementation cannot be ignored as iron and zinc have been shown to competitively inhibit each other's absorption. Biochemical analysis during pregnancy can help us to diagnose the specific nutrient deficiency and provide ideal therapeutic measures.
