This study aimed to determine the burden of anemia and its determinants among pregnant women with helminthiasis attending antenatal care at tertiary Hospitals in western Uganda. Methods: A hospital-based cross-sectional study was conducted from 1st November 2022-1st March 2023, enrolling 420 pregnant women diagnosed with helminthiasis attending antenatal clinics. Data were collected via interviewer-administered questionnaires and laboratory records. Descriptive statistics and multivariable logistic regression analyses were performed using IBM SPSS version 23 to identify factors independently associated with anemia. Results: The prevalence of anemia was 26.2% (95% CI: 22.2-30.6), with 39.1% (95% CI: 30.5-48.4) mild, 35.5% (95% CI: 27.1-44.7) moderate, and 25.5% (95% CI: 18.2-34.3) severe cases.
