Observational University of Oxford · NCT05973552

This study is trying to find out how much iron pregnant and breastfeeding women in Kenya need and how well their bodies absorb it to help improve their health and nutrition.

What this trial studies

This observational study aims to determine the iron requirements and absorption in pregnant and lactating women living in Kenya. By enrolling 250 women in their first trimester who previously participated in an iron absorption study, researchers will utilize stable iron isotope techniques to assess iron levels in the body. The study will follow Kenyan guidelines for prenatal care while focusing on the unique challenges faced by women in Sub-Saharan Africa regarding iron deficiency. The findings could provide critical data to inform dietary recommendations and healthcare practices for this population.

Who should consider this trial

Good fit: Ideal candidates are pregnant women in their first trimester who have previously participated in an iron absorption study and meet specific health criteria.

Not a fit: Patients who are not pregnant, have a high pre-pregnancy BMI, or have major chronic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved dietary guidelines and healthcare strategies for pregnant and lactating women, reducing the risk of anemia.

How similar studies have performed: While studies on iron absorption exist, this specific approach using stable isotopes in pregnant women in Sub-Saharan Africa is relatively novel.
