Results After the intervention, both the proportion of young students MSM had sex and with multiple sex partners decreased (χ 2 = 12.12, 5.94, P <0.05). The comprehensive ability of AIDS prevention has improved significantly, the "National Eight Items" correct rate has risen from 90.0% to 99.0% (χ 2 = 5.82, 7.56, P <0.05), and the "Youth Eight Items" correct rate has increased from 86.0% to 98.0% ( P <0.01). Knowledge score increased from (11.08±1.89) to (11.84±1.27); Attitude score increased from (54.29±4.01) to (56.06±3.75), the behavior score increased from (52.12±4.78) to (55.08±4.25), skill score increased from (51.96±4.75) to (54.67±5.04), The comprehensive prevention ability score (percent) increased from (87.30 ±6.95) to (91.86±5.42) ( t = −4.21, −3.51, −5.32, −5.16, −6.45, P <0.01).
