Methods A cross-sectional survey was conducted in Chongqing Municipality. According to convenient sampling, undergraduates, junior college students, and technical secondary school students were selected to investigate their knowledge, attitudes, and behaviors related to AIDS, and the logistic regression model was performed to analyze the influencing factors on separation of knowledge-behavior. Results A total of 2 870 school youth were included, of whom 40.9% showed a separation of knowledge and behavior. The logistic regression findings indicated that those aged 18-19 years old(OR=0.641, 95%CI: 0.469-0.875) and those aged ≥20 years old(OR=0.534, 95%CI: 0.389-0.732), school type was higher vocational education/junior college(OR=1.248, 95%CI:1.038-1.501) and technical secondary school(OR=1.443, 95%CI: 1.039-2.003), monthly expenditure was ≥3 000 Yuan(OR=1.459, 95%CI: 1.019-2.090), frequency of sexual behavior was >3 times in the past year(OR=1.618, 95%CI: 1.383-1.893), sexual partner was not a spouse or in a relationship(OR=1.667, 95%CI: 1.329-2.092), those have not actively inquired about AIDS(OR=1.168, 95%CI: 1.001-1.369) and haven’t received AIDS propaganda in school in the past year (OR=1.269, 95%CI: 1.071-1.505), were the affecting factors on separation of knowledge and behavior(P<0.05).
