Early sexual intercourse among American adolescents represents a major public health problem. Although early sexual activity may be caused by a variety of factors, the media are believed to play a significant role. In film, television, and music, sexual messages are becoming more explicit in dialogue, lyrics, and behavior. In addition, these messages contain unrealistic, inaccurate, and misleading information that young people accept as fact. Teens rank the media second only to school sex education programs as a leading source of information about sex. Recommendations are presented to help pediatricians address the effects of the media on sexual attitudes, beliefs, and behaviors of their patients.
