What Are the Epidemiological Methods Used to Study Air and Water Quality?
Several epidemiological methods are employed to study the impact of air and water quality on health. These include:
- Cross-sectional studies: Assess the prevalence of health outcomes in relation to current air or water quality. - Cohort studies: Follow a group of individuals over time to determine how exposure to contaminants affects health outcomes. - Case-control studies: Compare individuals with a health condition to those without to identify potential exposure risks. - Ecological studies: Analyze data at the population level to identify correlations between environmental quality and health metrics.
