ObjectiveTo know the status of knowledge， attitude and behavior related to sexual and reproductive health in high school students in three regions of East China， and to provide a reference for adolescent reproductive health education.
MethodsFrom August to October in 2019， 614 high school students were invited from 6 high schools in Jiading District and Yangpu District， Shanghai and Taicang City， Jiangsu to participate in this study. We conducted an anonymous self-questionnaire survey using structured questionnaires based on adolescent reproductive health knowledge and literacy.
ResultsThe male to female ratio of all high school students in the study was 1∶1.25， and the average age was （16.1±0.9） years old. The score of pregnancy and abortion knowledge was the lowest among the reproductive health knowledge scores， and the differences among the three regions were statistically significant （P=0.002）. Male high school students （P<0.001）， students in the school with reproductive health education base （P=0.008） and students who wanted to obtain reproductive health education （P=0.002） were more acceptable to premarital sex. The high school students obtained adolescent health knowledge mainly through the internet or mobile phones， and had a demand for reproductive health related services.
ConclusionHigh school students in the three regions have a more open attitude towards premarital sex， but have a poor grasp of correct and efficient contraceptive knowledge. Responsible departments need to strengthen the health education of relevant knowledge， and at the same time to find new forms of education to effectively improve the level of adolescent reproductive health.
