About this trial
Young women living with obesity (OB) have a greater risk of developing iron deficiency. Plus, the risk of anemia and/or ID in young women living with overweight (OW) and obesity (OB) is further increased by inadequate dietary intake and/or poor bioavailability of iron, as well as gastrointestinal and menstrual iron losses. It is not certain whether women living with OW/OB can meet their iron requirements from their day-to-day diet.
The aim of this study is to compare iron absorption and losses over a long period between women living with and without OW and OB. Secondary outcomes include iron and inflammation status, as well as dietary iron intake.
