Abstract: Objective To understand the current situation of sexual behavior and cognition among adolescent students, and to analyze the influencing factors of sexual intercourse, so as to provide a basis for formulating targeted interventions to reduce the adverse consequences of adolescent sexual behavior. Methods Using a stratified cluster sampling method, 1 228 adolescents from six vocational schools in Shandong Province were selected from August to October 2022. Questionnaires were used to collect information related to general characteristics, sexual knowledge, sexual concepts and behavior, and social norm cognition. An electronic version of the questionnaire was developed and distributed through the commonly used platform, Wenjuanxing. Results Among the 1 228 students, 242 (19.7%) were male and 986 (80.3%) were female. Out of the total sample, 77 (6.3%) reported having engaged in sexual intercourse, with 75 (97.4%) of them engaging in risky sexual behaviors. The overall score of sexual knowledge among students in the six schools was 21.41 ± 5.93. Logistic regression analysis revealed that being male (OR=3.342, 95%CI:1.919 - 5.818), being older than 16 years (OR=2.095, 95%CI=1.049 - 4.181), having migration experience (OR=1.764, 95%CI:1.016 - 3.064), being in a romantic relationship (OR=6.812, 95%CI=3.806 - 12.192), approving of sexual behavior outside marriage (OR=2.486, 95%CI:1.174 - 5.262), approving of one night stand (OR=3.263, 95%CI:1.197 - 8.899), and agreeing that condoms cannot be used for one-time sexual intercourse (OR=6.804, 95%CI:2.797 - 16.548) were risk factors for engaging in sexual behavior. Conclusions The prevalence of sexual behavior among adolescents is low, but the prevalence of risky sexual behavior is high. It is recommended to adopt a multi-party collaborative approach to intervene high-risk groups, aiming to promote the physical and mental health of adolescents.
