Indigenous women experience a complex spectrum of mutually reinforcing human rights abuses which is influenced by intersecting forms of discrimination and marginalization, reinforced by patriarchal power structures and past and present forms of violations of the right to self-determination and control of resources. These intersecting forms of discrimination have profound health consequences for indigenous women, especially for their reproductive and sexual health. The Special Rapporteur on the rights of indigenous peoples has reported (see A/HRC/30/41) about the barriers to reproductive and sexual health services encountered by indigenous women as well as past and recurrent human rights violations in relation to their sexual and reproductive rights. For example, indigenous women experience disproportionately higher levels of maternal mortality, indigenous girls are overrepresented among pregnant teenagers and indigenous women have lower rates of contraceptive use and higher rates of sexually transmitted diseases, including HIV/AIDS. Historically, there have also been instances of serious violations of indigenous women's rights to reproductive health in the context of the denial of the rights of indigenous peoples to self-determination and cultural autonomy. Those violations include forced sterilization of indigenous women and attempts to force them to have children with non-indigenous men as part of policies of cultural assimilation. Indigenous women may also face barriers to preventive care services that support their right to health, such as screening for ovarian and breast cancer.
