直接面向消费者（DTC）的基因检测可以通过互联网购买。一些公司声称提供各种疾病的相对遗传风险，从而鼓励健康行为。有人担心，接触这些信息实际上可能会阻碍健康行为或增加健康焦虑。进行了在线调查（n = 275）。受访者包括购买DTC基因检测并收到结果的个人（消费者，n = 189），以及正在等待检测结果或考虑购买检测的个人（潜在消费者，n = 86）。消费者被问及他们的健康行为或健康焦虑是否在收到结果后发生了变化。询问并比较被调查者目前的健康行为和健康焦虑。总的来说，27.3%的消费者声称健康行为发生了变化，所有这些变化都是积极的或中性的，没有报告停止任何现有的健康行为。24.6%的消费者声称健康焦虑发生了变化，其中85.3%的人减少了。消费者的健康行为评分明显优于潜在消费者（p = 0.02），但在健康焦虑方面没有显著差异。这项研究指出，基于自我报告，收到DTC基因检测结果与少数消费者增加健康行为的采用之间存在关联，与健康焦虑有关的结果更为复杂。
Direct-to-consumer (DTC) genetic tests can be purchased over the internet. Some companies claim to provide relative genetic risks for various diseases and thus encourage healthy behaviour. There are concerns that exposure to such information may actually discourage healthy behaviour or increase health anxiety. An online survey was conducted (n = 275). Respondents were composed of individuals who had purchased a DTC genetic test and received their results (consumers, n = 189), as well as individuals who were either awaiting test results or considering purchasing a test (potential consumers, n = 86). Consumers were asked if their health behaviour or health anxiety had changed after receiving their results. Respondents' current health behaviour and health anxiety were queried and compared. In total, 27.3 % of consumers claimed a change in health behaviour, all either positive or neutral, with no reported cessation of any existing health behaviour. A change in health anxiety was claimed by 24.6 % of consumers, 85.3 % of which were a reduction. Consumers had significantly better health behaviour scores than potential consumers (p = 0.02), with no significant difference in health anxiety. This study points towards an association between receipt of DTC genetic test results and increased adoption of healthy behaviours for a minority of consumers based on self-report, with more mixed results in relation to health anxiety.
