- Obstetrics and Gynecology
- Public Health
- Nutritional Science
Background:
- Anemia during pregnancy is a significant global health concern.
- Understanding regional prevalence and risk factors is crucial for targeted interventions.
- Previous studies highlight socioeconomic and lifestyle factors influencing maternal anemia.
Purpose of the Study:
- To determine the prevalence of anemia among pregnant women in Changsha.
- To identify key factors influencing the occurrence of anemia during pregnancy.
- To provide evidence-based recommendations for anemia prevention and management in this population.
Main Methods:
- A retrospective cohort study was conducted with 713 mothers in Changsha.
- Data on maternal health information during pregnancy were collected post-delivery.
- A nested case-control study with conditional logistic regression analyzed influential factors.
Main Results:
- The prevalence of anemia during pregnancy in Changsha was found to be 9.96%.
- Beneficial factors included higher income, education, folic acid, iron supplements, and blood product consumption.
- Risk factors identified were multiparity, longer menstrual periods, new housing, and tea consumption.
Conclusions:
