Knowledge about mammography and associated factors: population surveys with female adults and elderly

Abstract

The purpose of this paper is to describe the knowledge about mammography and to identify associated factors in female adults and elderly. Data were obtained from two population surveys, one with female adults and another with elderly women from Florianópolis (SC) in 2009 - 2010. A descriptive analysis of the variables was carried out, the appropriate mean of responses about mammography was estimated and crude and adjusted Poisson regression was conducted to identify associated factors. Among adults, 23.1% answered all of the questions appropriately and the appropriate average responses was 7.2 (95%CI 7.1 - 7.3) in a total of 9. In the adjusted model, older age, higher education and income were associated with knowledge about mammography. For the elderly, 15.3% answered all questions appropriately and the average of appropriate responses was 6.4 (95%CI 5.2 - 6.5) and the factors associated with knowledge about mammography in the adjusted model were younger age groups, increased education and income, and identification of mammography as the main diagnostic method for breast cancer. Information about mammography can neither be transmitted in a clear way nor be easily understood; there are also demographic and socioeconomic differences concerning the knowledge about the exam.

Knowledge about Risk Factors for Breast Cancer and Having a Close Relative with Cancer Affect the Frequency of Breast Self-Examination Performance

“…Recent Brazilian literature about early breast cancer detection is mainly focused on women's knowledge about prevention and mammography performance (Santos and Chubaci, 2011;Azevedo et al, 2012;Schneider et al, 2013;Vieira et al, 2015). Few Brazilian studies have assessed women's knowledge about BSE and underlying reasons for its performance: Most descriptive Brazilian studies about BSE, that mainly focused on intervention including small groups of women, have been conducted in southern regions of the country (Nascimento et al, 2009;Araujo et al, 2010;Kim et al, 2010;Grego et al, 2011;Silva and Riul, 2011;Gomes et al, 2012).…”

Risk factors of breast cancer and knowledge about the disease: an integrative revision of Latin American studies

“…In contrast, 16 studies on the knowledge and awareness about BC cited mainly previous publications of their own country written in Spanish or Portuguese (p < 0.0001). There were only four studies on the knowledge and awareness that mainly cited literature published in English [24][25][26][27] .…”

“…The authors pointed to socio economic and geographic barriers, limiting possibilities of ED. Similarly, the authors of studies carried out in Brazil exclusively focused on women's knowledge about ED emphasized the existence of social and geographical barriers that limit possibilities of mammography and clinical breast examination 26,60 . Silva et al, pointed out in their study that ED techniques have been largely studied in developed countries and little is known about their efficiency in developing countries 25 .…”

“…Schneider et al, showed in their study that women with low income, no private health insurance and low educational level participate less frequently in mammography screening programs 26 . Older women had in general better knowledge about ED than younger ones 26,58,64,65,66 . In a study from Venezuela, the authors report- Personal history of breast cancer 27, 55, 68…”

Age-dependent impact of breast cancer risk perception on mammography screening behavior in Brazilian women

“…In Northeast Brazil, women often present at advanced stages of disease (Stage III and IV). High breast cancer mortality rates were attributed to non-adherence to the MS program [5][6][7]. Brazilian studies identified high income as the most important predictor of adherence [5,8,9].…”
