HONG KONG: Most Hong Kong youngsters have checked out pornographic websites - and about a fifth of them did it before they turned 10, according to research by the Hong Kong Polytechnic University.

The survey showed nearly 80 percent of 10- to 17-year-olds viewed online porn and the average age for a first encounter among the 1,426 surveyed was younger than 12.

More than 85 percent accessed porn from home.
