A study on women's practice of breast self-examination in Taiwan.

Abstract

A questionnaire interview was conducted on a sample of 3,040 women ages 30-59 years in the Taipei area through multistage sampling with probability proportional to size. Excluding mistakes in household registration, there were 2,311 qualified subjects, 1,749 of whom (75.7%) completed the interview. The study framework was set up according to Green's PRECEDE model. In the results of this study only 8.4% of the subjects performed breast self-examinations monthly, and no single step of the breast self-examination procedure had a correct rate above 30%. The most remarkable associative factor for the correctness of breast self-examination was "source of instruction," a variable of "enabling factors"; other variables with strong associations were "newspaper contact" (contact with health reports in newspapers), which also belongs to the enabling factors category and "knowledge of breast cancer," a "predisposing factor." Demographic factors such as "educational level" and "urbanizational level" were only indirectly related. The authors suggested using all possible routes of health education, such as mass media, hospitals and clinics, and distribution of information in the workplace, to instruct and encourage breast self-examination, especially among women from rural communities and those with less education.
