Nearly 63 percent of Chinese youths aged 6 to 17 sleep less than eight hours a day, according to the report. Among 13 to 17-year-olds the figure is more than 81 percent. The report was based on a survey at the end of last year and in January. It covered nearly 70,000 children and teens aged 6 to 17 across the Chinese mainland, Hong Kong, Macao and Taiwan.
