Final answer:
The presence of adolescent parents in the family is associated with a high risk of adolescent pregnancy.
Step-by-step explanation:
The presence of family members, especially parents; siblings who are adolescent parents, is associated with a high risk of adolescent pregnancy. This means that when parents and siblings are teenage parents, there is a higher likelihood that other family members, such as siblings, may also become pregnant during adolescence. This may be due to various factors, including social and environmental influences within the family.
