There has been much discussion of the utility and validity of the earlobe crease as a warning sign of cardiovascular disease. The authors postulated that the mixed findings were due to the neglect of three variables: age, race, and earlobe shape. Age and earlobe shape were studied in 324 healthy adult subjects from three racial groups: southwestern Alaskan Eskimos (70), Navajos (167), and whites (87). It was found that creases develop with age in healthy adults, that creasing is related to earlobe shape, that the age of onset of creasing varies according to race, and that the frequencies of occurrence of different earlobe shapes differ by race. Future studies of earlobe creases should therefore include the variables of age, race, and earlobe shape.
关于耳垂折痕作为心血管疾病警示信号的效用和有效性，已经有很多讨论。作者推测，研究结果不一的原因是忽略了三个变量：年龄、种族和耳垂形状。对来自三个种族群体的324名健康成年受试者进行了年龄和耳垂形状的研究：阿拉斯加西南部爱斯基摩人（70名）、纳瓦霍人（167名）和白人（87名）。研究发现，健康成年人的折痕会随着年龄增长而出现，折痕与耳垂形状有关，折痕出现的起始年龄因种族而异，不同耳垂形状的出现频率也因种族不同而有所差异。因此，未来关于耳垂折痕的研究应纳入年龄、种族和耳垂形状这些变量。
