More and more teenagers are becoming pregnant, Shanghai Morning Post reports.

An official with the Shanghai Municipal Population and Family Planning Commission said that the number of induced abortions among teenagers at local hospitals this year had increased roughly 20 to 30 per cent over last year.

The youngest was only 13 year old, said the official who asked not to be named.

The paper cautioned parents that they should pay more attention to the physical situation of their children.
