Anemia in the Internal Medicine Department of the Borgou-Alibori Departmental University Hospital Center: A 2025 Study

---

Résumé

Introduction: Anemia remains a major challenge in medical care, particularly
in developing countries. This study aimed to investigate anemia in the Internal
Medicine Department of the Borgou-Alibori Departmental University Hospital
Center (CHUD/BA) in 2025. Methods: This was a descriptive cross-sectional
study with an analytical component and prospective data collection conducted
from January 1 to August 31, 2025. The study population consisted of adult
patients hospitalized in the Internal Medicine Department of CHUD/BA who
provided informed consent, either personally or through a relative. Anemia was
the dependent variable. Binary logistic regression was used to identify factors
associated with anemia. A p-value < 0.05 was considered statistically significant.
Results: A total of 369 patients were included, with a mean age of 44.81
± 16.98 years and a male predominance (56.91%). The prevalence of anemia was
72.63%. Anemia was moderate and microcytic in 57.46% and 42.91% of cases,
respectively. Infectious causes accounted for 54.10% of anemia cases, predominantly
bacterial infections. Among non-infectious causes, chronic kidney disease
and solid malignant tumors were the most frequent, representing 53.66%
and 30.08%, respectively. In multivariate analysis, factors independently associated
with anemia were asthenia, conjunctival pallor, melena, and malnutrition.
Conclusion: The majority of patients hospitalized in the Internal Medicine
Department in Parakou were anemic. The causes of anemia were multiple
and heterogeneous.
