The World Health Organization on Tuesday launched a new comprehensive analysis of global health trends since 2000 and an assessment of the challenges for the next 15 years, a UN spokesman said here.

The report, entitled Health in 2015: from the Millennium Development Goals (MDGs) to the Sustainable Development Goals (SDGs), identifies key drivers of progress in health since 2000.

SDGs, approved by world leaders here in September, are the blueprint for the global development efforts for the next 15 years. It replaces MDGs, a set of eight anti-poverty goals to be reached by its deadline of the end of 2015.

"It also lays out actions that countries and the international community should prioritize to achieve the SDGs," Farhan Haq, the deputy UN spokesman, told reporters here.

According to the report, the past 15 years witnessed major declines in child and maternal mortality as well as progress in the fight against HIV, TB and malaria in developing countries, he added.
