Exposure to Sources of Heart Disease Prevention Information: Community Type and Social Group Differences

Community pluralism predicted both exposure to sources of heart disease prevention information and diversity of source exposure in three Upper Midwest cities (small, medium, large) over a ten-year period. Community differences in both outcomes narrowed, however. The study suggested that during the 1980s, the sheer amount of information about the topic of heart disease prevention and the proliferation of electronic media reduced typical community system and SES-based differences in exposure.
