Alcohol consumption is a potentially modifiable risk factor for breast cancer (BC). Reducing alcohol consumption within the daily amount at low-risk for alcohol-related consequences (daily alcohol threshold) may contribute to preventing BC new cases. However, most women are unaware of risk factors for BC, the daily alcohol threshold, and how to measure alcohol use. We aimed at investigating the efficacy of accessing an interactive website in increasing the knowledge that alcohol is a BC risk factor.
We conducted a randomized controlled trial among women waiting for mammography. Women completed a questionnaire to investigate their knowledge before and after accessing an interactive (intervention group) and non-interactive (control group) website.
We recruited 671 women, randomized 329 (49.0 %) and 342 (51.0 %) to the intervention and control groups, respectively. At baseline, most women were not aware of most modifiable BC risk factors. Accessing either website significantly increased the percentage of women who acquired the knowledge on BC risk factors, with the interactive website achieving better results: 82 % and 69 % of women acquired the knowledge that alcohol is a risk factor for BC in the intervention and control groups, respectively (p < 0.001). Among women with lower levels of education, the probability of acquiring this knowledge was higher in the intervention group than control group.
Our results show that accessing an interactive website may increase the percentage of women who acquire the knowledge that alcohol is a BC risk factor especially among women of lower levels of education.
饮酒是乳腺癌（BC）一个潜在的可改变风险因素。在与酒精相关后果处于低风险的每日饮酒量范围内（每日酒精阈值）减少饮酒量，可能有助于预防BC新发病例。然而，大多数女性并不知晓BC的风险因素、每日酒精阈值以及如何衡量酒精摄入量。我们旨在调查访问一个交互式网站在增加人们对酒精是BC风险因素这一认识方面的效果。
我们在等待乳房X光检查的女性中进行了一项随机对照试验。女性在访问交互式网站（干预组）和非交互式网站（对照组）之前和之后完成一份调查问卷，以调查她们的知识水平。
我们招募了671名女性，分别将329名（49.0%）和342名（51.0%）随机分配到干预组和对照组。在基线时，大多数女性并不知晓大多数可改变的BC风险因素。访问任何一个网站都显著提高了了解BC风险因素的女性比例，其中交互式网站取得了更好的效果：干预组和对照组分别有82%和69%的女性了解到酒精是BC的风险因素（p<0.001）。在教育程度较低的女性中，干预组获得这一知识的概率高于对照组。
我们的结果表明，访问交互式网站可能会提高了解酒精是BC风险因素的女性比例，尤其是在教育程度较低的女性中。
