Recently, there has been interest in determining whether diet is associated with the risk of venous thromboembolism. The article by Varraso et al. (Am J Epidemiol. 2012;175(2):114-126) published in this issue of the Journal is an important contribution to this literature. In this commentary, the author discusses the findings of Varraso et al. within the context of the existing literature and posits epidemiologic explanations for why investigators might have failed to identify strong associations between diet and venous thromboembolism.
最近,人们对饮食是否与静脉血栓栓塞风险有关产生了兴趣。Varraso 等人在本期《美国流行病学杂志》上发表的文章(Am J Epidemiol. 2012;175(2):114-126)为这一文献做出了重要贡献。在这篇评论中,作者根据现有文献讨论了 Varraso 等人的研究结果,并提出了一些流行病学解释,说明为什么研究人员可能未能发现饮食与静脉血栓栓塞之间的强烈关联。
