Results The average age of 1 864 students was （16.27±1.20） years old, the awareness rate of AIDS prevention and treatment was 52.90% （986/1 864）, and the incidence of sexual behavior was 5.63% （105/1 864）. There were 8.53% （159/1 864） of the students had tried to find sexual partners through various network channels such as social software/websites/online games, with an average age of （16.35±1.20） years.
