Combined iron and zinc supplementation improves haematologic status of pregnant women in Upper West Region of Ghana.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

To determine the impact of zinc deficiency on iron status indicators in pregnant women.

Who Took Part

The age groups tagged for this paper are young adults and adults, women only.

A double-blind, randomized controlled trial (RCT) of joint iron and zinc supplementation.

The study population comprised pregnant women who presented themselves for antenatal care (ANC) in the Wa Regional Hospital of the Upper West Region in Ghana.

How the Study Was Run

In design terms this was a randomized and double-blind study.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

The study was conducted in the Upper West Region of Ghana, where the prevalence of anaemia is high.
