An intervention study on screening for breast cancer among single african-american women aged 65 and older.

PURPOSE: Older single African-American women are the population that is least likely to use screening procedures because of cognition-related, income-related, social-support-related and medical care-related barriers. This study aims to evaluate a breast screening intervention program developed according to socioeconomic, cultural, psychological and behavioral characteristics of older single African-American women.METHODS: Ten public housing complexes were randomly assigned to either intervention or control group. African-American women aged 65 and over were recruited into the study if they were widowed, divorced, separated or never-married in the preceding year, and did not have a history of breast cancer (n = 325). Delivered by lay health educators, the intervention program targeted increasing knowledge on breast health and breast screening, reducing emotional or psychological problems, and increasing support from the significant others of study women. Breast screening-related cognition and behavior were measured at pre-intervention and post-intervention.RESULTS: Comparisons of the pre-intervention and post-intervention measurements showed that while the proportion of women who had a clinical breast examination or mammogram in the preceding year was decreased at the post-intervention in the control group, it was increased in the intervention group. However, the differences did not reach a significant level. No consistent patterns could be found in changes of variables in knowledge, attitudes and beliefs. These results remained similar when potential confounding factors were adjusted using mixed model regression analyses.CONCLUSIONS: These results did not suggest significant effects of an intervention program which used lay health educators to promote breast cancer screening in older single African-American women.
