To assess the knowledge, attitude and practice of breast self-examination (BSE) of women from the municipality of São Luís (MA), Brazil, and associated socio-demographic variables.
Prospective and cross-sectional study, with conglomerate sampling, in which 552 women from 14 census sections of São Luís were included during the period from January to September 2003. The knowledge, attitude and practice (dependent variables) were evaluated by means of analysis of the responses of the women as "adequate" or "inadequate". The main independent variables were: age, schooling, family income and marital and menopausal status. The χ² test was used to determine the association between categorical variables and the measurement of the crude/adjusted Odds Ratio (OR) after multivariate analysis by means of logistic regression.
Although 1/3 of the studied population did not know about BSE, the group of women who were informed about it showed adequate knowledge (60.9%), practice (59.5%) and attitude (90%). The family history of breast cancer (8.9%) was not associated with better knowledge and practice. The media (63.6%) was found to be important in disseminating information about BSE. After multivariate analysis, women with a partner (OR=1.9) presented more adequate knowledge; women older than 50 years (OR=11.7) had a better attitude towards BSE; women with more than five years of schooling (OR=2) and with a partner (OR=1.7) were associated with a more correct practice of BSE.
Most of the patients know and practice the BSE in São Luís and their attitude towards the procedure is extremely positive. There was a great participation of the media in the dissemination of information concerning BSE.
评估巴西圣路易斯市（马塞约）女性的乳房自我检查（BSE）知识、态度和行为以及相关的社会人口统计学变量。
采用前瞻性横断面研究，整群抽样，于2003年1月至9月期间纳入了圣路易斯市14个普查区的552名女性。通过分析女性的回答为“充分”或“不充分”来评估知识、态度和行为（因变量）。主要自变量为：年龄、受教育程度、家庭收入以及婚姻和绝经状态。采用χ²检验确定分类变量之间的关联，并通过逻辑回归进行多变量分析后测量粗/调整比值比（OR）。
尽管三分之一的研究人群不知道BSE，但了解BSE的女性群体显示出充分的知识（60.9%）、行为（59.5%）和态度（90%）。乳腺癌家族史（8.9%）与更好的知识和行为无关。发现媒体（63.6%）在传播BSE信息方面很重要。多变量分析后，有伴侣的女性（OR = 1.9）知识更充分；50岁以上的女性（OR = 11.7）对BSE态度更好；受教育年限超过五年的女性（OR = 2）和有伴侣的女性（OR = 1.7）与更正确的BSE行为相关。
圣路易斯市的大多数患者了解并进行BSE，她们对该检查的态度极为积极。媒体在传播有关BSE的信息方面发挥了很大作用。
