This is a study of the association of radio and television exposure with different aspects of reproductive behavior and with knowledge, attitudes, and behavior in connection with HIV/AIDS. The measures of mass media are limited to the frequency that women and men report listening to the radio and watching television, which are standard questions in the Demographic and Health Surveys (DHS). Only the frequency is assessed; the DHS does not obtain information on programmatic content. The first part of the report focuses on contraceptive behavior, the number of children desired, and the number of births in the preceding three years. The second part of the study focuses on 27 countries in sub-Saharan Africa and explores the implications of radio and television exposure for HIV/AIDS knowledge, attitudes, and risk behavior.
