Evolving capacity of children and their best interests in the context of health research in South Africa: An ethico-legal position.

The existing ethico-legal regulation of adolescent children's participation in health research in South Africa is currently unclear. The article interrogates the existing framework governing children's consent to research participation, with specific emphasis on discrepancies in consent norms in law and ethical guidelines. Against the backdrop of the constitutional directive that requires that a child's best interests are of paramount importance in every matter concerning the child, the article assesses whether sufficient consideration is given to children's evolving maturity and capacities when consent to their participation in health research is sought. The article provides specific recommendations and proposes a legislative change to consent provisions in the National Health Act 61 of 2003 in order to address the existing lacunae and to align the framework with constitutional imperatives and international fundamental rights considerations.
