[Research on abortion in Brazil: gaps and challenges for the public health field].

This paper provides a review of abortion studies produced in the field of public health in Brazil, highlighting current research gaps and challenges. Most studies focus on women admitted to public hospitals for treatment of incomplete abortion, so their scope is limited to abortions presenting complications. Women's profiles, abortion methods, motives, and immediate consequences for women's physical health are also included. However, there remains a need for studies on the following aspects: measuring abortion incidence; investigating cases of post-abortion complications and death; analyzing the relationship between abortion and contraception; investigating the impact of abortion on women's mental health; and incorporating men's perspectives. There is an urgent need for evaluative research on abortion care in public services. Research results should be disseminated widely, so as to help overcome any ideological bias in the current debate on abortion rights in the country.
