Adolescent pregnancy Health Article

Definition

Adolescent pregnancy is pregnancy in girls age 19 or younger.

Alternative Names

Teenage pregnancy; Pregnancy - teenage

Causes, incidence, and risk factors

The rate of adolescent pregnancy and the birth rate for adolescents have generally declined since reaching an all-time high in 1990, mostly due to the increased use of condoms.

Adolescent pregnancy is a complex issue with many reasons for concern. Younger adolescents (12 - 14 years old) are more likely to have unplanned sexual intercourse and more likely to be coerced into sex. Adolescents 18 - 19 years old are technically adults, and half of adolescent pregnancies occur in this age group.

Risk factors for adolescent pregnancy include:

• Younger age
• Poor school performance
• Economic disadvantage
• Single or teen parents

Symptoms

Pregnancy symptoms include:

• Abdominal distention
• Breast enlargement and breast tenderness
• Fatigue
• Light-headedness or actual fainting
• Missed period
• Nausea/vomiting
• Frequent urination

Signs and tests

The adolescent may or may not admit to being involved sexually. If the teen is pregnant, there are usually weight changes (usually a gain, but there may be a loss if nausea and vomiting are significant). Examination may show increased abdominal girth, and the health care provider may be able to feel the fundus (the top of the enlarged uterus).

Pelvic examination may reveal bluish or purple coloration of vaginal walls, bluish or purple coloration and softening of the cervix, and softening and enlargement of the uterus.

• A pregnancy test of urine and/or serum HCG are usually positive.
• A pregnancy ultrasound may be done to confirm or check accurate dates for pregnancy.
