Relationships between these educational variables and adolescents' sexual attitudes and behaviors were analyzed in a sample of 810 high school students from two Western States. Parents' educational background was positively related to adolescents' educational plans and performance, and these educational variables were inversely related to adolescents' premarital sexual attitudes and intercourse experience. It seems most plausible to conclude that parents' educational backgrounds affect children's educational interests and grades, which, in turn, affect adolescent sexuality. However, the observed associations also could be interpreted to suggest that early sexual behavior reduces adolescents' educational plans and lowers their school grades. (Author abstract)
