Primary Endpoint
1. Comparison of the proportion of anemic and/or iron-deficient women among those who receive and do not receive oral iron supplements (OIS) in the first trimester

Study Overview

Brief Summary

Rationale/ gaps in existing knowledge

Iron deficiency (ID) is highly prevalent in the first trimester of pregnancy. However, current guidelines of the Anemia Mukt Bharat program in India do not recommend oral iron supplements (OIS) in the first trimester. It is unclear whether such supplementation would be beneficial to reduce iron deficiency and anemia during pregnancy.  This proposal aims to address this lacuna.

Novelty

There is little Indian data on the benefits of starting OIS in the first trimester of pregnancy, instead of only in the second trimester (current national recommendations), to reduce iron deficiency and anemia during pregnancy.  This is an important question to answer, given the burden of anemia in pregnancy in India.

Objectives

To compare the effectiveness of starting OIS in the first trimester versus starting it only in the second trimester, in reducing the prevalence of anemia during pregnancy.

Methods and expected outcomes

In a randomized controlled double-blind trial, pregnant women will receive either placebo or low-dose (30 mg elemental iron) OIS in the first trimester. From the second trimester onwards, they will all receive supplements as per standard of care. Participants will be monitored through pregnancy till delivery.  Blood samples will be obtained in each trimester and at the time of delivery.  Cord blood and placental tissue samples will also be obtained.

The proportion of women in each group with ID/anemia at delivery will be ascertained. Blood samples  will be used for estimation of hematological and iron-related indices.  Placental tissue will be used to determine indices related to iron homeostasis. Outcomes of pregnancy will be documented.

Outcomes

Primary Outcomes

1. Comparison of the proportion of anemic and/or iron-deficient women among those who receive and do not receive oral iron supplements (OIS) in the first trimester

Time Frame: At the time of delivery of each woman in the study

Time Frame: At the time of delivery of each woman in the study

Secondary Outcomes
