BACKGROUND
Many people report uncertainty about their cancer risk. We examined whether such uncertainty was related to cancer prevention and detection behaviors.
METHODS
National Health Interview Survey data from 2005 to 2010 were analyzed. Participants reported their perceived risk for colorectal and breast cancers. Responses were coded as "valid" (i.e., less/as/more likely than average) or "don't know."
RESULTS
In bivariate analyses for both cancer sites and survey years, "don't know" responders (DKR) engaged in less physical activity than "valid" responders (p < 0.05). DKR had lower mammography adherence than "valid" responders in 2005 and lower colorectal screening adherence in 2010 (p < 0.05). DKR had marginally lower colorectal screening adherence and fruit/vegetable consumption in 2005 (p < 0.06). Multivariable models indicated that the DKR-behavior relationship could be largely accounted for by education.
CONCLUSION
Interventions that help people understand their cancer risk may provide particular benefit to people with low education and might consequently reduce health disparities.
背景
许多人表示对自身患癌风险存在不确定性。我们研究了这种不确定性是否与癌症预防和筛查行为有关。
方法
分析了2005年至2010年的国家健康访谈调查数据。参与者报告了他们对结直肠癌和乳腺癌的感知风险。回答被编码为“有效”（即低于/等于/高于平均水平）或“不知道”。
结果
在针对癌症部位和调查年份的双变量分析中，“不知道”的回答者（DKR）比“有效”回答者进行的体育活动更少（p < 0.05）。2005年，DKR的乳房X光检查依从性低于“有效”回答者，2010年其结直肠癌筛查依从性更低（p < 0.05）。2005年，DKR的结直肠癌筛查依从性和水果/蔬菜摄入量略低（p < 0.06）。多变量模型表明，DKR与行为之间的关系在很大程度上可由教育来解释。
结论
帮助人们了解自身癌症风险的干预措施可能对低教育水平人群特别有益，从而可能减少健康差距。
