What are the Challenges in Epidemiological Assessments?
Conducting epidemiological assessments involves several challenges:
- Bias: Systematic errors that can affect the validity of study results. Common types include selection bias, information bias, and confounding. - Confounding: When the effect of the primary exposure on the outcome is mixed with the effect of another variable. - Ethical Considerations: Ensuring informed consent, maintaining confidentiality, and balancing risks and benefits.
