Deficiencies vs. Differences: Predicting Older Women’s Knowledge
Levels on Breast Cancer
Abstract: Breast cancer has replaced lung cancer as the most commonly diagnosed cancer among US women. As breast cancer risks increase with age, older women constitute a particularly vulnerable group. As the primary source of health information for the public, mass media assume a vital role in fostering breast cancer awareness and knowledge. Applying the knowledge gap hypothesis to the health domain, this study assessed the level of media publicity on breast cancer, evaluated older women’s knowledge on this issue and its relationship with: education, perceived risk and mammography experience. The net influence of each of these competing variables on knowledge outcomes was also weighed and their interaction effects tested by the study. Data from the 1992 National Health Interview Survey (NHIS) were used to test the hypothesized knowledge gaps while a separate content analysis was conducted to measure the media environment of breast cancer during the period under study. Secondary analysis found significant knowledge gaps among older women based on all education and motivational variables, but no interaction effects were supported. Interpretations, guidance to future studies and policy implications were discussed.

been among the health priorities listed by the Office of Women’s Health. In 2002 an
estimated number of 203,500 US women will be diagnosed of invasive breast cancer and
39,600 are estimated to die from the disease, and for all efforts to identify the BCC gene,
breast cancer incidence and mortality rates showed a consistent socio-demographic
pattern (American Cancer Society, 2002).
