The COVID-19 pandemic saw a surge in anxiety and major depressive disorders across the world - in particular among women and young people.

The study, published in the Lancet, said that young people suffered as school closures kept them away from friends, while many women found themselves doing the bulk of household work and faced an increased risk of domestic violence.

It recorded 76 million additional cases of anxiety disorders and 53 million of major depressive disorder as COVID-19 spread in 2020.

"Sadly, for numerous reasons, women were always more likely to be worse affected by the social and economic consequences of the pandemic," study co-author Alize Ferrari said.

"Additional caring and household responsibilities tend to fall on women, and because women are more likely to be victims of domestic violence, which increased at various stages of the pandemic."
