This review summarizes the experimental literature on behavioral outcomes and psychological effects of genetic testing for obesity. Such tests, although of dubious value, are increasingly marketed to the public, and there has been concern that while results may encourage some consumers to increase the healthfulness of their lifestyles, others may interpret feedback in maladaptive ways.
Hypothetical vignettes have been used in artificial settings; few studies have investigated outcomes of actual test results. At present, the effects of genetic testing for obesity seem limited to improving consumers' weight control intentions and motivation rather than actual dietary behavior. Evidence for negative psychological consequences is scarce and seems of greater concern for normal weight persons than for those who are overweight. Better research designs carried out in the field rather than the laboratory with more diverse samples are needed.
本文总结了肥胖基因检测的行为结果和心理影响的实验文献。尽管这些检测的价值值得怀疑，但它们仍越来越多地推向公众市场，人们担心的是，尽管检测结果可能会鼓励一些消费者提高生活方式的健康度，但其他人可能会以不适应的方式来解释反馈。
在人为环境中使用了假设的情景；很少有研究调查实际检测结果的结果。目前，肥胖基因检测的效果似乎仅限于改善消费者的体重控制意图和动机，而不是实际的饮食行为。关于负面心理后果的证据很少，而且对于正常体重的人来说，似乎比超重的人更令人担忧。需要在实验室以外的领域进行更好的研究设计，采用更多样化的样本。
