The specific department within the U.S. Department of Health and Human Services (HHS) that regulates research involving children is the Office for Human Research Protections (OHRP). The regulations that apply to research with children are outlined in the Code of Federal Regulations (CFR), specifically in Title 45, Part 46, Subpart D. This subpart is often referred to as the "Subpart D regulations."

The Subpart D regulations provide additional protections for children involved in research to ensure their rights and welfare are safeguarded. Researchers conducting studies with children must adhere to these regulations, which include requirements for obtaining informed consent from parents or guardians and assent from the children when appropriate. The goal is to balance the need for research with the protection of children who may be involved in research studies.
