IntroductionSince the 1970s, in many countries around the world, the problem of adolescent sexuality and first sexual experience at a young age has emerged. To make matters worse, the trend of teenage pregnancies has become increasingly serious. According to the World Health Organization fact sheet, about 16 million adolescent girls give birth each year – most in low- and middle-income countries. Among them, an estimated three million girls aged 15 to 19 undergo unsafe abortion each year. In low- and middle-income countries, more than 30% of girls marry before the age of 18; about 14% before the age of 15, and complications related to pregnancy and childbirth are a leading cause of death among girls aged 15 to 19. In mainland China, with the deepening of reform and opening-up, the concept of sexual behavior has also changed significantly, especially adolescents. Unmarried teenage pregnancies are increasingly concentrated in the crowd, with unmarried teenagers inflicting enormous physical and psychological trauma on them. Due to China's cultural context, it is not practical to obtain an exact figure on teenage pregnancies, let alone how the problem will develop in the future. The question of “早戀” has already become a taboo at school. Schools and parents act like detectives, tracking every detail and trying to hush up potential relationships in the cradle. However, the atmosphere of avoidance of gender issues in school and society leads to inaccurate gender knowledge that students receive as they attempt to acquire this knowledge through unreliable resources. In order to change the situation, this action plan was implemented, aiming to reduce the percentage of teenage pregnancies in schools while providing scientific and student-friendly sex education.Background...... middle of article......
