Objective To analyze the status quo of birth control in grass-roots health care institutions so as to provide a theoretical basis for the rational promotion and standardization of post-abortion services.MethodQuestionnaires about birth control were taken by women who had induced abortion in Changsha Hospital for Maternal & Child Health Care of Hunan Province and Anshun Hospital for Maternal & Child Health Care of Guizhou Province and the data were statistically analyzed.Results Among 197 cases from Changsha Hospital and 172 cases from Anshun Hospital

those with low levels of education had more abortion than those with high levels of education and the difference was statistically significant（P<0.05）.The risk factors for induced abortion were levels of education and whether to have the guidance of contraceptive knowledge or not.No contraception was the main reason why pregnant women from the two hospitals had abortion.Conclusions Medical workers should disseminate targeted contraception knowledge to people from different regions

in different stages of pregnancy

with different abortion experiences and from different educational or economic levels and guide them to choose different contraceptives in order to reduce the risk of contraceptive failure

enhance the effectiveness of contraception and improve women’s reproductive health in their region.
