An epidemiological survey in ten family health units in the municipality of Teresópolis, Rio de Janeiro State, Brazil, in 2003, investigated the distribution pattern of breast cancer risk factors. 698 women 25 to 88 years of age were interviewed (112 rural and 586 urban). As for factors associated with breast cancer, 36.1% were 50 years or older, 3.7% had a first-degree family history, and 0.4% had a prior diagnosis of breast cancer. As for other factors, prevalence was higher in women with a history of abortion (38.5%), breastfeeding of less than one year (37.4%), prolonged use of oral contraceptives (41.1%), low physical activity (58.7%), and obesity (30%). Although the latter factors are still under investigation and the measures found in studies show weak associations, they are relevant to public health, not only for breast cancer control but also for other diseases, since their prevalence is high in the population.
2003年，在巴西里约热内卢州特雷索波利斯市的十个家庭健康单位开展了一项流行病学调查，以研究乳腺癌风险因素的分布模式。研究人员对698名年龄在25至88岁之间的女性进行了访谈（其中112名来自农村，586名来自城市）。在与乳腺癌相关的因素方面，36.1%的女性年龄在50岁及以上，3.7%的女性有一级家族病史，0.4%的女性曾被诊断出患有乳腺癌。在其他因素方面，有流产史的女性（38.5%）、母乳喂养时间不足一年的女性（37.4%）、长期使用口服避孕药的女性（41.1%）、身体活动量低的女性（58.7%）以及肥胖女性（30%）的这些因素患病率更高。尽管后述这些因素仍在研究之中，且研究中发现的相关措施显示关联较弱，但它们与公共卫生相关，不仅关乎乳腺癌防控，还涉及其他疾病，因为它们在人群中的患病率很高。
