Objective: To understand and analyze the situation of contraceptive use among women seeking abortions in Shanghai. Methods: The computer-assisted anonymous questionnaire was used to collect data among 1 261 women seeking abortions in 4 hospitals in Shanghai from August to October in 2013. Results: Nearly 60% of the respondents were under the age of 29 and 32.6% were unmarried. Over 50% of the respondents reported having abortion experiences before. Compared with those married women, the unmarried women had a higher proportion of unprotected intercourse (48.0% vs. 33.9%) and a lower proportion of contraceptive use failure (38.6% vs. 47.8%). Logistic regression analysis indicated that younger or sexually inactive women tended not to take contraceptive measures among those married respondents, and that those women who were young, unmarried, with a higher income or a history of abortion were more likely to use emergency contraception. Conclusions: Young women with high proportion of repeated abortion constituted the majority of respondents in Shanghai. Two main factors of unwanted pregnancy are the low proportion of contraceptive use and the high proportion of failure use of contraceptives. It is important to strengthen the post-abortion care services and the contraceptive education, especially to teach them how to use contraceptives, because those induced abortion women were lack of contraceptive precaution or knowledge.

Objective: To explore heterosexual and homosexual behaviors, and influencing factors, in those unmarried out-of-school young people aged 15 to 24 years, so as to provide the basis on the education and service of sexual and reproductive health for those young people. Methods: The questionnaire survey form was anonymously filled out by 1 113 unmarried out-of-school young people on six target spots in urban and rural areas of six provinces by the computer assisted self-interview (CASI) system. Results: The incidences of hetero-or homo- sexual behaviors in the 15 to 18 years male group and the 19 to 24 years male group were significantly higher than those in female groups (P < 0.05). 7.14% of the first heterosexual behaviors in the 15 to 18 years female group were forced. Sexual safety precautions were used in 66.67% of males and 40.00% of females in the 15 to 18 years group, and in 58.82% of males and 49.11% of females in the 19 to 24 years group. About 30.00% of males reported that they had partners' pregnancies, and 30% of females reported that they had pregnancies. The incidence of multiple sexual partners in the 19 to 24 years male group was significantly higher than that in the age-matched female group (P < 0.01). On homosexual behaviors, the average age of the first homosexual behaviors in the 15 to 18 years group was about 14 years, 15.79% of males in the 19 to 24 years group were forced to have, and 46.15% of males and 33.33% females reported that they had more than two sexual partners. Multivariate analyses showed that watching pornographic materials and being older were common risk factors of heterosexual behaviors for males (OR, 3.51 and 3.81 respectively) and females (OR, 6.41 and 3.85 respectively). Compared with those factors approving premarital sexual behaviors, the attitudes rejecting premarital sexual behaviors from respondents themselves (OR = 0.18) and their parents (OR = 0.37), and the neutral attitude from friends (OR =0.47), were protective factors in males, while the options that the female respondents thought it being not good but acceptable (OR =0.14) or opposed (OR = 0.06), and that friends thought it being unacceptable (OR = 0.16) or unknown (OR = 0.21), were protective factors and the neutral attitude from parents was risk factor (OR = 12.56) in females. Conclusions: The incidences of heterosexual and homosexual behaviors, and unsafe sexual behaviors, in those unmarried out-of-school young people were high, which were positively related to the pornographic material and the open attitudes from respondents themselves, parents and friends.

Objective: To study the relationship between contraceptive use behaviors and related knowledge and cognition among vocational high school students., Methods: A computer-administrated anonymous cross-sectional survey was conducted among grade one students from three vocational high schools in a district of Shanghai. Based on Health Belief Model, four cognition indexes including perceived benefits, barriers, sex behavior related risks and self-efficacy were applied., Results: Among 1612 respondents, the students who had sexual experience accounted for 7.01% (113/1612). At first sex, 56.64% (64/113) of respondents reported contraceptives use; and the methods most reported were condom (58.70%, 27/46) and oral contraceptive (27.78%, 5/18) respectively for male and female. Most reasons for non-use were feeling shy to buy it (26.53%, 13/49) and the opposite sex's unwillingness to use (18.37%, 9/49). Among those who had experienced sex, 68.35% (54/79) and 68.42% (52/76) of respondents thought withdrawal and rhythm were effective methods. Only 23.26% (10/43) of subjects who had ever used condom could gain the full score of knowledge on how to use condom. A few respondents (22.86%, 24/105) who had sex experience knew that "If a person is infected with STD, he/she may not have noticeable symptoms". And 40.63% (26/64) of respondents who had not use contraceptive at first sex considered that "Infrequent intercourse cannot cause a girl pregnant even she has experienced her menstruation". The level of perceived risks was lowest among four cognition indexes. Contraceptive related knowledge and cognition may contribute to respondents' contraceptive use behaviors at first sex, and only related cognition contribute to contraceptive use behaviors at recent sex., Conclusion: It should be urgent to improve contraception knowledge and cognition among vocational high school students and provide youth-friendly contraceptive services.
