Abstract: Objective：To evaluate the intervention effect on contraceptive knowledge, attitude,
practice among college/university students, and to provide theoretical bases for further contraceptive education
in college/university. Methods：Questionnaires were conducted anonymously among college students before
intervention and half a year after intervention, and contraceptive knowledge，attitude and practice were
surveyed. Results：Compared with pre鄄intervention, the cognition regarding ovulation period and emergency
contraception were improved after intervention, the proportion of “most concerned about contraceptive
effectiveness in using contraception”was increased, but the proportions of“opposes the sexual liberation”and
“against unmarried cohabitation” were declined after intervention， the proportions of “always use
contraception”and “use condoms in sexual intercourse”were increased, and the prevalence of unintended
pregnancy was declined after intervention which showed significant difference（P＜0.01）. Conclusions：After
intervention, the rates of contraceptive knowledge and safe sex awareness are improved, but sex attitude
became more open among college students, which demonstrate that the special topic lecture is an effective
method to improve the contraceptive knowledge and practice among college/university students, however, sex
abstinence should be paid more attention in the further education.
