Abstract: Objective To explore the situation of choosing contraception and its risk factors among abortion women in Peking.Methods In January 2006,a study under the adoption of questionnaires was conducted among 611 abortion women,who had induced abortion 6 months ago in 8 hospitals,selected random from the hospitals in Peking.Results Among 577 abortion women 84.4% used condom,but only 20.7% could persist in using and use them correctly;42.3% didn't know the right usage among the women who used oral contraceptive.Among 559 abortion women who selected contraceptives,14.1% chose the traditional contraception.Single factor analysis showed that profession(χ²=21.090,P=0.000),income(χ²=6.878,P=0.032),registered permanent residence(χ²=13.515,P=0.000)and some factors of male partners were the risk factors;30.5% couldn't persist in using contraception after abortion.Multiple factors analysis showed that registered permanent residence(χ²=121497,P=01000),the reason of the latest abortion(χ²=51.49,P=0.023),and the attention of male partner(χ²=9.580,P=0.002)related with the women's contraceptive actions.Conclusion The rate of using contraceptives among post-abortion women is relatively high,but the rate of correct and persistent action is low and the male involvement contributes to the correct choice and persistent use of contraception.
