abstract="Since the 1970s, sexually transmitted diseases (STDs) (including human immunodeficiency virus infection and acquired immunodeficiency syndrome), unintended pregnancies, and other problems that result from sexual activity have increased among adolescents in the United States. For example, approximately 1 million adolescent girls become pregnant each year and 86% of all STDs occur among persons aged 15-29 years. This article presents self-reported data from 1990 about the prevalence of sexual intercourse, contraceptive use, condom use, and STDs among U.S. high school students.<p /><p>Language: en</p>",
