Special Protections for Children as Research Subjects

When a proposed research study involves children and is supported or conducted by HHS, the research institution's Institutional Review Board (IRB) must take into consideration the special regulatory requirements that provide additional protection for the children who would be involved in the research. If the proposed research involves FDA-regulated products, then FDA's parallel regulations apply.

FAQs on Research with Children

By regulatory definition, children are persons who have not attained the legal age for consent to treatments or procedures involved in the research, under applicable law of the jurisdiction in which the research will be conducted. Generally the law considers any person under 18 years old to be a child.

When reviewing research with children as subjects, in addition to ensuring adherence to the general regulatory requirements of 45 CFR part 46, Subpart A, the IRB also must consider the potential benefits, risks, and discomforts of the research to children and assess the justification for their inclusion in the research. In assessing the risks and potential benefits, the IRB should consider the circumstances of the children to be enrolled in the study-for example their health status, age, and ability to understand what is involved in the research-as well as potential benefits to subjects, other children with the same disease or condition, or society as a whole.

For any protocol involving children, the IRB must determine which of the four categories of research apply to that study, if any. OHRP recommends that the IRB document the rationale for this choice.

The HHS regulations at 45 CFR part 46, subpart D permit IRBs to approve three categories of research involving children as subjects:

    45 CFR 46.404 - Research not involving greater than minimal risk to the children.

    To approve this category of research, the IRB must make the following determinations:

    • the research presents no greater than minimal risk to the children; and
    • adequate provisions are made for soliciting the assent of the children and the permission of their parents or guardians, as set forth in HHS regulations at 45 CFR 46.408.

    45 CFR 46.405 - Research involving greater than minimal risk but presenting the prospect of direct benefit to the individual child subjects involved in the research.

    To approve research in this category, the IRB must make the following determinations:

    • the risk is justified by the anticipated benefits to the subjects;
    • the relation of the anticipated benefit to the risk presented by the study is at least as favorable to the subjects as that provided by available alternative approaches; and
    • adequate provisions are made for soliciting the assent of the children and the permission of their parents or guardians, as set forth in HHS regulations at 45 CFR 46.408.

    45 CFR 46.406 - Research involving greater than minimal risk and no prospect of direct benefit to the individual child subjects involved in the research, but likely to yield generalizable knowledge about the subject's disorder or condition.

    In order to approve research in this category, the IRB must make the following determinations:

    • the risk of the research represents a minor increase over minimal risk;
    • the intervention or procedure presents experiences to the child subjects that are reasonably commensurate with those inherent in their actual, or expected medical, dental, psychological, social, or educational situations;
    • the intervention or procedure is likely to yield generalizable knowledge about the subject's disorder or condition which is of vital importance for the understanding or amelioration of the disorder or condition; and
    • adequate provisions are made for soliciting the assent of the children and the permission of their parents or guardians, as set forth in HHS regulations at 45 CFR 46.408.

A fourth category of research requires a special level of HHS review beyond that provided by the IRB.
