Early Sexual Intercourse and Early Pregnancy

By: Quinlan, Robert J.

Analyzing data from the National Survey of Family Growth, these researchers find that women whose parents separated between their birth and age 5 experienced 4 times the risk of having early sexual intercourse and 2.5 times the risk of an early pregnancy; women whose parents separated between ages 6-11 had 2.7 times the risk of early sexual intercourse and 1.8 times the risk of an early pregnancy; and women whose parents separated between ages 12-17 had 2 times the risk of early sexual intercourse and 1.5 times the risk of early pregnancy.
