There are still 650 million early married women and girls alive around the world today. As of 2020, globally around 21% of young women were married before their 18th birthday and 12 million girls under 18 are married each year. Even before the COVID-19 outbreak, 100 million girls were at risk of child marriage in the next decade, yet as a result of the pandemic, an additional 10 million girls will be at risk of early marriage.

The United Nations Educational Scientific and Cultural Organization (UNESCO) also estimates that nearly 24 million children and adolescnets, including 11 million girls and young women, may drop out of school due to the economic impact of COVID-19. School closures increase the risk of a girl's early marriage by 25% per year and shorten the period of attendance at school by 7 months. 2% of girls fail to return to school, and will continue to face a higher risk of early marriage. Girls are socially isolated, as well as taken precious young age. They are away from family and friends and are limted from education and employment.

Child marriage also negatively influence their health. Girls want safe sex with condoms, but they have difficulty in demanding contraception. The result is exposure to sexually transmitted diseases such as HIV and early pregnancy. 

UN Sustainable Development Goals 5 'Achieve Gender Equality and Empower All Women and Girls' includes eliminating all harmful practices, such as child, early and forced marriage and female mutilation by 2030 in Target 5.3 International society is making its efforts in various ways for it. 

Girls from developing countries get married at an early age and low in using contraceptive methods, showing a high birth rate. This tendency seriously affects their health. Girls’ pregnancy negatively When a girl gets pregnant and gives birth, she doesn’t get proper antepartum care on poverty and nutrition deficiency. Uncompleted physical development can expose more girls than adult women to postpartum bleeding, obesity, mental disorder, fetal or newborn death, and fistula.

Especially in the cases of girls’ delivery in the age from 12 to 20, the possibility that children die before the age of 5 or underweight and anemia occur is higher. Studies also showed that diseases such as rubella, virus infection such as HIV, obesity, nutrition deficiency, and gestational diabetes and health-related actions such as alcohol and smoking of girl mothers affect children’s health. Especially when young ladies are under obstructed labor, the possibility of fetus death goes up to 95%, and the mother’s death goes up to 8%. Therefore, providing intensive health and medical service to fetuses and newborns is improving maternal health and mortality rate, and what is more important is keeping girls from child marriage and early pregnancy and preventing them from getting health damage or from missing educational opportunities.
