To investigate the awareness and knowledge level of breast cancer among Chinese participants.
Case-control study.
This study was based on the database of the minister-affiliated hospital key project of the Ministry of Health of the People's Republic of China that included 21 Chinese hospitals between April 2012 and April 2013.
Matched study was designed among 2978 participants with Han ethnicity aged between 25 and 70.
Student's t-test, Pearson's χ test, reliability analysis, exploratory factor analysis, and univariate and multivariate logistic regression analyses were performed to know the level of breast cancer knowledge and find the breast cancer awareness-associated factors.
80.0% (2383/2978) of the participants had poor awareness level of breast cancer. In-depth knowledge of breast cancer such as early symptoms and risk factors was poorly found among them. Television broadcast and relatives or friends with breast cancers were the main sources of information about breast cancer. Of all participants, 72.8% (2167/2978) had heard about breast cancer as a frequent cancer affecting women, and 63.3% (1884/2978) knew that family history of breast cancer was a risk factor for breast cancer. Over half of them were aware that a breast lump could be a symptom of breast cancer. Multivariate analysis identified the following variables that predicted awareness of breast cancer: young age (OR=0.843, 95% CI 0.740 to 0.961), occupation (agricultural worker) (OR=12.831, 95% CI 6.998 to 23.523), high household social status (OR=0.644, 95% CI 0.531 to 0.780), breast hyperplasia history (OR=1.684, 95% CI 1.273 to 2.228), high behavioural prevention score (OR=4.407, 95% CI 3.433 to 5.657).
Most women were aware of breast cancer as a disease, but their in-depth knowledge of it was poor. More publicity and education programmes to increase breast cancer awareness are necessary and urgent, especially for the ageing women and agricultural workers.
调查中国参与者对乳腺癌的知晓情况和知识水平。
病例对照研究。
本研究基于中华人民共和国卫生部部属医院重点项目数据库，该数据库涵盖了2012年4月至2013年4月期间的21家中国医院。
对2978名年龄在25至70岁之间的汉族参与者进行匹配研究。
采用学生t检验、Pearson卡方检验、可靠性分析、探索性因子分析以及单因素和多因素逻辑回归分析，以了解乳腺癌知识水平并找出与乳腺癌知晓相关的因素。
80.0%（2383/2978）的参与者对乳腺癌的知晓水平较低。他们对乳腺癌的深入知识，如早期症状和危险因素了解甚少。电视广播以及患有乳腺癌的亲戚或朋友是乳腺癌信息的主要来源。在所有参与者中，72.8%（2167/2978）听说过乳腺癌是影响女性的常见癌症，63.3%（1884/2978）知道乳腺癌家族史是乳腺癌的一个危险因素。超过一半的人意识到乳房肿块可能是乳腺癌的症状。多因素分析确定了以下预测乳腺癌知晓情况的变量：年轻（OR = 0.843，95%CI 0.740至0.961）、职业（农业工人）（OR = 12.831，95%CI 6.998至23.523）、家庭社会地位高（OR = 0.644，95%CI 0.531至0.780）、乳腺增生病史（OR = 1.684，95%CI 1.273至2.228）、行为预防得分高（OR = 4.407，95%CI 3.433至5.657）。
大多数女性知道乳腺癌这种疾病，但对其深入了解较差。有必要且迫切需要开展更多宣传教育项目以提高乳腺癌知晓率，尤其是针对老年女性和农业工人。
