Environmental epidemiology: basics and proof of cause-effect

Area of Science:

• Environmental Epidemiology
• Toxicology
• Public Health

Background:

• Understanding disease causality requires integrating epidemiology and toxicology.
• Environmental epidemiology aims to identify disease determinants and distributions for public health improvement.
• Key challenges include commitment to purpose, data complexity, and effective communication.

Purpose of the Study:

• To explore the interconnected problems of commitment, complexity, and communication in integrating epidemiology and toxicology.
• To determine the sufficiency of evidence required for public health (preventive) actions.
• To enhance the application of toxicological evidence in environmental epidemiology.

Main Methods:

• Systematic narrative reviews.
• Criteria-based inference methods.
• Meta-analysis.

Main Results:

• Causal inference in environmental epidemiology relies on qualitative methods.
• Integrating evidence across multiple scientific levels (molecular to social) presents complexity.
• The relevance and application of toxicological evidence in public health practice remain key issues.

Conclusions:

• Effective communication of methodological practices is crucial for combining evidence from diverse scientific levels.
• Addressing challenges in commitment, complexity, and communication is vital for advancing environmental epidemiology.
• Strengthening the link between toxicological findings and public health interventions is essential.
