Objective To get a general picture of the attitudes of middle school educators on sex and reproductive health education. Methods A cross-sectional survey was carried out among 144 middle school educa- tors in three districts of Shanghai from September to October 2005 using anonymous self-administered questionnaire. Results The majority of the educators thought that it was necessary to launch the sex and reproductive health education in all of the middle schools in Shanghai (97.02%). They were aware that the age of the students’ puberty were earlier now than before (94.41%), but the reproductive health knowledge of students was neither sufficient nor correct (78.34%).The sex and reproductive health education had been involved in the curriculum of many middle schools (66.11%). Lacking of qualified education staffs contributed most (90.71%) in the schools which had not launched the sex and repro- ductive health education. Lacking of qualified education staffs (90.91%) challenged most in the schools which had carried the education. Conclusion The middle school educators thought it was necessary to carry the sex and reproductive health education in all of the middle schools in Shanghai while the major challenges were lacking of qualified education staffs and sufficient teaching time.
