The Teen Period Study (T-DOT): Understanding Patterns of Menstruation and Risk Factors for Iron Deficiency After a Girl’s First Period
Purpose
The purpose of this research is to determine normal menstrual patterns, as well as the risk factors for iron deficiency (not enough iron in the blood).
Participants will:
- Track their menstrual patterns using the Teen Period (T-Dot) app over 2 years
- Complete online (virtual) study visits every six months
- Have four blood draws to test iron levels at the beginning of the study, then at 8 months, 16 months and 24 months. Blood draws will be done in the participant’s home.
