A Comparative Study of Plasma Trace Elements (Copper, Iron and Zinc) Status in Anaemic and Non-anaemic Pregnant Women in Abakaliki, Nigeria

Abstract

For a comparative study of plasma copper, iron and zinc between anaemic and non-anaemic pregnant women, data for anaemic (n = 223) and non-anaemic (n = 126) pregnant women drawn from a cohort of 351 pregnant Nigerians recruited at gestational age of ≤ 25 weeks for the study of impacts of trace element status on pregnancy outcomes were analysed. With the exception of plasma copper which was significantly (p 0.05) in the former. While plasma copper, iron and zinc concentration were not correlated with maternal haemoglobin concentration, plasma zinc significantly correlated negatively (r = -0.141, p < 0.05) with plasma copper. It is thus concluded that anaemia in pregnant women in this population may partly be due to a combination of trace element deficiencies and their interactions with each other. While interventions should go beyond improving intakes, more research is desired to clearly define these interactions.
