The attitudes towards LGBT was (65.44±20.01), the attitudes towards sexual and healthy behaviors was (67.04±49.23), and the attitudes towards sexual relations and behaviors was (70.75±10.46).

The results of multivariate Logistic regression analysis showed that students’ sexual knowledge was related to region, grade and school-based sexuality education (OR=2.11,P<0.05).@*Conclusion@#Junior high school students have sexual needs and behaviors, but their sexual knowledge is not sufficient; there are differences in sexual knowledge and attitudes of junior high school students across region,grade and gender; schools should promote school-based sexuality education for junior high school students’ sexual health.
