    <dc:title>Database Introduction: A Retrospective Study on Prophylactic Iron Supplementation with Shengxuening Tablet for Preventing Iron Deficiency Anemia in Pregnancy</dc:title>
    <dc:publisher>Mendeley Data</dc:publisher>
    <dc:description>1. Background  
Iron homeostasis, crucial for physiological function, is disrupted during pregnancy due to impaired absorption (from gestational reactions and altered gut motility) and escalating fetal demands (post-16 weeks). Approximately 25% of women require increased iron intake in late gestation .  
Iron deficiency (ID) progresses to iron deficiency anemia (IDA), elevating risks of adverse outcomes:  
Maternal: Preterm premature rupture of membranes (PPROM), gestational hypertension, puerperal infection  
Fetal/Neonatal: Growth restriction (FGR), preterm birth, low birth weight (LBW)  
Regional epidemiology in China reveals significant disparities :  
ID prevalence: East China (57.37%), Northeast (53.41%), Southwest (30.51%)  
IDA prevalence: Central South (21.30%), Northwest (16.97%), East China (17.53%)  
Prophylactic low-dose iron supplementation is recommended internationally to prevent ID→IDA progression while mitigating risks of iron overload.  
2. Rationale and Objectives  
 Pathophysiological Basis  
Serum ferritin &lt;16.4 μg/L at 12 weeks signals need for intervention .  
Pregnancy triples iron requirements vs. menstruation, reaching 30 mg/day elemental iron in mid-late gestation.  
 Once stores deplete, dietary iron is insufficient; oral supplementation (100–200 mg/day for IDA) is essential.  
Non-anemic women with ferritin &lt;30 μg/L require 60 mg/day elemental iron.  
 Iron excess risks gut dysbiosis [10] and gestational diabetes (GDM).  
 Shengxuening (SXN) Advantage  
Active compound: Sodium ferrous chlorophyllin (heme iron) with superior bioavailability vs. non-heme iron.  
Mechanism: Downregulates hepcidin and upregulates ferroportin to enhance iron absorption/transport.  
Clinical evidence: A 498-patient multicenter trial demonstrated significantly lower anemia incidence with SXN vs. elemental iron or no supplementation.  
3. Study Design and Objectives  
This large-scale retrospective database study addresses critical evidence gaps by evaluating:  
 Primary Objectives  
1. Iron Status &amp; IDA Prevention:  
   Impact of prophylactic SXN on maternal iron biomarkers (serum ferritin, serum iron) and IDA incidence.  
2. Maternal Outcomes:  
   Association with gestational diabetes (GDM), hypertensive disorders, preterm birth (&lt;37 weeks), postpartum hemorrhage (PPH), and postpartum anemia.  
3. Neonatal Outcomes:  
   Influence on low birth weight (LBW; &lt;2500g), neonatal asphyxia, and fetal distress.  
 Scientific Value  
By analyzing real-world data, this study will:  
Establish efficacy of SXN in maintaining iron sufficiency  
Evaluate safety profile for major maternal-fetal complications  
Provide evidence for optimized prophylactic iron protocols.
