Identify factors associated with knowledge of breast cancer and estimation of risk.
Telephone survey of 412 women aged 40 and over, living in Montreal and selected by random digit dialing.
The majority of the respondents had recently been exposed to some information on breast cancer, but only a third quoted the average lifetime probability estimate of about 1 in 10. Older individuals systematically considered themselves at low risk (odds ratio (OR) of perceiving risk as lower than average for women aged 50 or over versus under 50: 2.6, 95% confidence interval: (1.5, 4.6)). In addition, both a first-degree family history of breast cancer (OR: 5.3 (1.7, 17.0)) and a recent mammogram (OR: 3.0 (1.4, 6.2)) were strongly associated with a woman's probability of perceiving herself at high risk.
Information campaigns should emphasize the frequency of breast cancer in different age groups and the strength of the established associations with specific risk factors. Better knowledge of risk could promote sustained participation in breast screening programs.
确定与乳腺癌知识及风险评估相关的因素。
对412名年龄在40岁及以上、居住在蒙特利尔的女性进行电话调查，采用随机数字拨号方式选取。
大多数受访者近期接触过一些关于乳腺癌的信息，但只有三分之一的人提到了约十分之一的平均终生患病概率估计值。年龄较大的人往往认为自己风险较低（50岁及以上女性认为自身风险低于平均水平的优势比（OR）与50岁以下女性相比为2.6，95%置信区间：（1.5，4.6））。此外，乳腺癌一级家族史（OR：5.3（1.7，17.0））和近期乳房X光检查（OR：3.0（1.4，6.2））都与女性认为自己处于高风险的概率密切相关。
宣传活动应强调不同年龄组乳腺癌的发病率以及与特定风险因素已确定的关联强度。对风险有更好的了解可以促进持续参与乳腺癌筛查项目。
