Behaviors that result in potential exposure to human immunodeficiency virus (HIV) usually begin in adolescence or young adulthood, but trends in HIV incidence in young people remain unclear. ⋯ In young persons, HIV incidence in homosexual men and injection drug users was slowing by 1993; this favorable trend was offset by increasing heterosexual transmission, especially in minorities.

Sudden death in young competitive athletes due to unsuspected cardiovascular disease has heightened concern and interest in the preparticipation screening available to high school athletes in the United States. ⋯ Preparticipation athletic screening for cardiovascular disease with standard history and physical examination, as presently employed in US high schools, is highly dependent on the state-approved questionnaires, which frequently are abbreviated and may be inadequate; is implemented by a variety of health care workers with varying levels of expertise; and may be severely limited in its power to detect potentially lethal cardiovascular abnormalities. These observations should represent an impetus for change and improvement in the preparticipation cardiovascular screening process for high school athletes.
