Intervensjon / Behandling |
|---|---|
|
Eksperimentell: Preconception Group
Townships assigned to this group implement anemia screening and indicated iron treatment before conception.
|
Women planning pregnancy within 6 months undergo hemoglobin, hemoglobin electrophoresis, and serum ferritin assessments before conception.
Those with hemoglobin levels below 120 g/L and/or serum ferritin levels below 30 μg/L receive oral ferrous succinate (0.2 g twice daily) plus vitamin C, with scheduled hematologic monitoring.
|
|
Aktiv komparator: Early-Pregnancy Group
Townships assigned to this group implement the same anemia screening and indicated iron treatment during early pregnancy.
|
Women with a singleton pregnancy at 12 weeks' gestation who have hemoglobin levels below 110 g/L and/or serum ferritin levels below 30 μg/L will receive oral ferrous succinate (0.2 g twice daily) plus vitamin C, with scheduled hematologic monitoring

Proportion of participants with iron deficiency anemia during late pregnancy
Tidsramme: From 28 weeks' gestation to delivery
|
Iron deficiency anemia is defined as a hemoglobin concentration of less than 110 g/L and a serum ferritin concentration of less than 20 μg/L, measured in the same blood sample.
Participants meeting both criteria at least once during any scheduled assessment from 28 weeks' gestation through delivery will be classified as having the primary outcome.
