There are serious health risks for adolescents who have babies. Young adolescents (particularly those under age 15) experience a maternal death rate 2.5 times greater than that of mothers aged 20-24. Common medical problems among adolescent mothers include poor weight gain, pregnancy-induced hypertension, anemia, sexually transmitted diseases (STDs), and cephalopelvic disproportion. Later in life, adolescent mothers tend to be at greater risk for obesity and hypertension than women who were not teenagers when they had their first child.
