Gestational Follow-up: Secondary Cohort

Once the pregnancy was confirmed, the women were followed-up monthly until delivery. Clinical, obstetrical, and anthropometric data, as well as malaria infection screening data, were collected. A gestational age (GA) estimation was based either on the last menstrual period or first ultrasound scan [26]. A TBS and an RDT were performed in the case of a fever or malaria-like symptoms. According to recommendations in Benin (at least 2 doses during pregnancy), IPTp was given from the second trimester.
