The rate of girls under the age of 14 who undergo female genital mutilation (FGM) in Africa has seen a “huge and significant decline” over nearly three decades, according to a new analysis.
The study, published Wednesday in the global health journal BMJ, drew on data from two prior surveys that covered nearly 210,000 children in 29 countries between 1990 and 2017, Agence France-Presse reports.
An estimated 200 million women and girls around the world are estimated to have suffered the traditional mutilation, which experts and rights advocates say has devastating consequences on women’s physical and psychological health, including complications during childbirth. Some countries have made efforts to ban FGM outright.
The BMJ study found the steepest decline in East Africa, where FGM rates fell from 71.4% in 1995 to just 8% in 2016. (FGM has historically been widely prevalent in East Africa: a 2016 UNICEF report found that 98% of women and girls in Somalia experienced genital cutting.)

Other African regions exhibiting declining rates were North Africa, where the percentage of girls who underwent FGM decreased from 57.7% to 14.1% between 1990 and 2015, and West Africa, where the rate fell from 73.6% in 1996 to 25.4% in 2017.
But the study also found that in two Middle Eastern countries, Yemen and Iraq, the rate of girls undergoing FGM actually increased.
Researchers also expressed concerns that growing stigma around FGM may discourage families from reporting it in areas where it is still practiced.
“Preventing FGM should be a major public health priority in countries and regions still showing a high prevalence among children,” Ngianga-Bakwin Kandalathe, the study’s lead author, told AFP.
While the study’s authors acknowledged that outlawing FGM may help contribute to its decline, they also advocated for “culturally sensitive” efforts to deter it in regions where the procedure still retains strong cultural and traditional associations.
