Three hundred thirty-two laborers in a shipyard, all of whom had been working for decades in heavy industry, were compared with regard to the occurrence of coxarthrosis with a similar sized group of white-collar workers and with a random population sample. All three sets of men were of the same age. About one-fourth (the same in all three groups) had been referred for a hip roentgenographic examination at some time over the previous decades. In the group of laborers and their white-collar controls, coxarthrosis occurred in about 3%, with no difference between the two samples. The occurrence was less, but not significantly less, in those men who had been randomly selected from the population.
将一家造船厂的332名劳动者与规模类似的白领工人组以及随机抽取的人群样本进行比较，这些劳动者都在重工业领域工作了几十年。所有三组男性年龄相同。在过去几十年中的某个时候，约四分之一的人（三组情况相同）被转诊进行髋部X光检查。在劳动者组及其白领对照组中，髋关节炎的发生率约为3%，两组样本之间无差异。在从人群中随机选取的男性中，发生率较低，但差异不显著。
