Participant Flow

Screening for the study subjects was conducted in July, 2010 among the adolescent schoolgirls in Nyaung Done Township, Irrawaddy Division. It included assessment of Hb status using the Coulter Counter. Information on the general characteristics and menarche status of the girls are obtained.

Deworming with 400 mg Albendazole was done one week before the baseline data collection.
