Objective: To understand the general information of adolescent girls with unplanned pregnancy and the information about abortion and reproductive health knowledge, analyze the influencing factors of unplanned pregnancy and explore the preventive measures. Methods: Using epidemiological investigation method, the adolescent females (age <19 years old) who volunteered requested pain deprivation in our hospital from January 2018 to December 2019 were examined by questionnaire with informed consultation, and the results were analyzed. Results: After screening, 98 valid questionnaires were received. The average age of girls were 16.81 years old, and the youngest was 13 years old. Employed girls accounted for 54.0%, students for 23.5% and unemployed people for 22.5%. Non-earners accounted for 38.8%, and those with monthly income less than 3,000 yuan accounted for 86.8%. 78.6 of those aged 16-18 had sex for the first time. The age of first sexual intercourse ?15 years old accounted for 21.4%. The first abortion patients accounted for 84.7%, repeated abortion accounted for 15.3%. years old accounted for 19.05%. First abortion in the age ?15 There was no statistical difference between the reproductive health knowledge mastery score and the family economic status, parents’ occupation, parents’ marital status, parents’ sex education (P >0.05). The score of reproductive health knowledge was statistically different from that of school sex education and hospital sex education (P <0.05). Conclusions: The primary cause of unintended pregnancy is the lack of knowledge of contraception and reproductive health. Schools and hospitals are effective in sex education for adolescent girls. Relevant government departments, schools, families and hospitals should pay more attention to sex education and strengthen efforts to improve the quality of education, so as to further reduce the harm caused by accidental pregnancy of adolescent girls.
