研究1)种族/民族和2)算术能力与DTC基因检测意识之间的关系。国家癌症研究所2007年健康信息全国趋势调查(HTINTS)对6754名西班牙裔、黑人和白人成年受访者进行了二次分析。使用Logistic回归分析DTC基因检测意识的社会人口学预测因素，包括种族/民族、收入、教育程度和性别。接下来，将两个计算变量添加到模型中。在控制了社会人口变量后，黑人受访者听说过DTC基因测试的可能性明显低于白人受访者(OR=0.79；CI：0.65-0.97)。加入计算变量后，黑人的影响不再显著(OR=0.84；CI：0.69~1.04)。西班牙裔受访者和白人受访者对DTC基因测试的认识没有显著差异。在完整模型中，DTC基因测试意识的其他重要相关因素包括教育、收入、年龄和计算变量，包括人们在多大程度上使用医疗统计数据和数字来做出健康决定，以及在讨论“发生某事的可能性”时对词语或数字的偏好。尽管黑人受访者普遍比白人受访者更不了解DTC基因测试，但这种关系似乎在一定程度上受到了算术能力的影响。
To examine the association of 1) race/ethnicity and 2) numeracy with awareness of DTC genetic tests. Secondary analysis of 6,754 Hispanic, black, and white adult respondents to the National Cancer Institute's 2007 Health Information National Trends Survey (HINTS). Logistic regression was used to examine sociodemographic predictors of DTC genetic tests awareness including race/ethnicity, income, education, and gender. Next, two numeracy variables were added to the model. After controlling for sociodemographic variables, black respondents were significantly less likely to have heard of DTC genetic tests compared to white respondents (OR = 0.79; CI: 0.65-0.97). When numeracy variables were added to the model, the effect of black race was no longer significant (OR = 0.84; CI: 0.69-1.04). Hispanic respondents did not significantly differ from white respondents in awareness of DTC genetic tests. Other significant correlates of DTC genetic tests awareness in the full model included education, income, age, and numeracy variables including degree to which people use medical statistics and numbers to make health decisions, and preference for words or numbers when discussing "the chance of something happening." Although black respondents were generally less aware of DTC genetic tests than white respondents, this relationship appears to be partially mediated by numeracy.
