What is the ethical foundation document for human subject research?

• A. Belmont Report.
• B. CIOMS Guidelines.
• C. Declaration of Helsinki.
• D. Nuremberg Code.

Answer: (C)

The Declaration of Helsinki is the primary international standard for medical research involving human subjects. It establishes clear ethical expectations that protect participants while guiding how research should be conducted. Key principles include obtaining voluntary informed consent, ensuring the study is scientifically sound and minimizes risks, requiring independent ethical review, and safeguarding privacy and vulnerable groups. It has been repeatedly revised to address new research methods and scenarios, which solidifies its role as the foundational reference used worldwide for human-subject research ethics. While other documents like the Nuremberg Code, Belmont Report, and CIOMS Guidelines are important, they do not constitute the global foundational framework in the same enduring way as the Declaration of Helsinki.
