Understanding dengue control requires community engagement. Knowledge significantly impacts practices, while economic status influences knowledge but not directly risk perception or practices for controlling Aedes aegypti breeding sites.
Area of Science:
- Public Health
- Vector-Borne Disease Epidemiology
- Behavioral Science
Background:
- Dengue reemergence highlights challenges in traditional control programs.
- Effective dengue control necessitates community-based strategies and behavioral change for Aedes aegypti management.
Purpose of the Study:
- To investigate the direct and indirect determinants of dengue-related practices.
- To analyze the relationships between economic status, knowledge, risk perception, and Aedes aegypti control practices.
Main Methods:
- Cross-sectional study involving 780 households in Havana, Cuba.
- Utilized questionnaires and observation guides to collect data on key variables.
- Employed Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to test a conceptual model.
Main Results:
- EFA identified five factors: Knowledge, Intradomiciliar risk practices, Peridomiciliar risk practices, Risk perception, and Economic status, explaining 74.3% of variance.
- CFA revealed that only Knowledge of dengue significantly and positively influenced Practices.
- Economic status directly correlated with Knowledge but not with Risk Perception or Practices.
Conclusions:
- Knowledge of dengue is a key direct determinant of control practices.
- Economic status indirectly influences practices through its effect on knowledge.
- Findings inform the design of community-based dengue control strategies emphasizing Information, Education, and Communication (IEC).
