In December 2012, 167 countries co-sponsored a biannual resolution of the United Nations General Assembly that called on all Member States to support the activities of UNFPA and its partners in the Campaign to End Fistula. The resolution also called for greater technical and financial support, in particular to high-burden countries, in order to accelerate progress towards achieving Millennium Development Goal 5: increasing maternal health, including eliminating obstetric fistula. It also underlined the need to accelerate effort to address child marriage. In addition, the UNFPA-backed resolution on Supporting Efforts to End Obstetric Fistula acknowledged the plight of millions of women and girls living with obstetric fistula by designating 23 May as the International Day to End Obstetric Fistula. The Day was observed for the first time in 2013.
