What Are The Causes and Consequences of Teenage Pregnancy

Babies born to mothers under 20 years of age face higher risks of low birth weight, preterm delivery and severe neonatal conditions. In some settings, rapid repeat pregnancy is a concern for young mothers, as it presents further health risks for both the mother and the child.

While the immediate health risks to both mother and child are a major cause for concern in teenage pregnancy, there is also a large economic impact. Babies born to mothers under 20 years of age face higher risks of low birth weight, preterm delivery and severe neonatal conditions. In some settings, rapid repeat pregnancy is a concern for young mothers, as it presents further health risks for both the mother and the child.

Teenage pregnancy can cause both the expectant mother and the child to face health risks. The baby may be born with low birth weight, or preterm delivery. In developing countries, rapid repeat pregnancy is very common in young women and presents further health risks for mother and child

Teenage pregnancy is a major public health concern in many of the world’s low- and middle-income countries. Although rates of teenage pregnancy have declined significantly since the mid-1980s, in 2014, 6.7 million children were born to women aged 15–19 years worldwide.

Teenage pregnancy is a serious problem in many countries. Because of their age, teenage mothers are more likely to die during pregnancy or childbirth than older women. Teenagers also have lower levels of education and income than older mothers do, which makes raising a baby more difficult.

What are the Causes of Teenage Pregnancy

Approximately 90% of births to girls aged 15-19 in developing countries occur within early marriage where there is often an imbalance of power, no access to contraception and pressure on girls to prove their fertility.

Factors such as parental income and the extent of a girl’s education also contribute. Girls who have received minimal education are 5 times more likely to become a mother than those with higher levels of education. Pregnant girls often drop out of school, limiting opportunities for future employment and perpetuating the cycle of poverty. In many cases, girls perceive pregnancy to be a better option than continuing their education.

In addition, the unique risks faced by girls during emergencies increase the chances of them becoming pregnant. Factors include the desire to compensate for the loss of a child, reduced access to information and contraception and increased sexual violence.

How does teenage pregnancy affect girls?

Adolescent pregnancy remains a major contributor to maternal and child mortality. Complications relating to pregnancy and childbirth are the leading cause of death for girls aged 15-19 globally. Pregnant girls and adolescents also face other health risks and complications due to their immature bodies. Babies born to younger mothers are also at greater risk. 

For many adolescents, pregnancy and childbirth are neither planned, nor wanted. In countries where abortion is prohibited or highly restricted, adolescents typically resort to unsafe abortion, putting their health and lives at risk. Some 3.9 million unsafe abortions occur each year to girls aged 15-19 in developing regions.

Adolescent pregnancy can also have negative social and economic effects on girls, their families and communities. Unmarried pregnant adolescents may face stigma or rejection by parents and peers as well as threats of violence. Girls who become pregnant before age 18 are also more likely to experience violence within a marriage or partnership.

How does Plan International support at-risk girls and teenage mothers?

We are committed to tackling adolescent pregnancy, especially among younger adolescents (aged 10-14) who are most at risk and yet often overlooked. We also support girls who have already become mothers.

By raising girls’ awareness of their sexual and reproductive health and rights, protecting them from abuse and connecting them with education and health services, we support the key decisions they make about their futures and bodies.

We call on governments to strengthen national health systems, implement comprehensive education on sexuality and relationships in and out of schools, and provide affordable, safe contraception to tackle the root causes of adolescent pregnancy. We also demand governments do more to support pregnant girls and young mothers to continue and complete their education.
