In 1992, levels of knowledge about the major modes of human immunodeficiency (HIV) transmission remained high in all sociodemographic groups examined. Knowledge about other aspects of acquired immunodeficiency syndrome (AIDS) was more variable with older and less educated adults generally being less knowledgeable. Changes in knowledge between 1991 and 1992 included: An increase from 86 to 95 percent in the proportion who had heard the AIDS virus referred to as "HIV" An increase from 15 to 22 percent in the proportion of young adults (18-29 years of age) who planned to be tested in the next year An increase from 13 to 17 percent in the proportion of adults who had a coworker, relative, or friend with AIDS An increase from 69 to 75 percent in the proportion of parents of 10-17-year-olds who had ever discussed AIDS with their children.
