Low-back pain and the occurrence of osteoarthritis were investigated among 226 lumberjacks employed in felling work for an average of 20 a. The reference group comprised 98 persons involved in either light physical work or office activities. There were no statistically significant differences between the two groups with regard to the occurrence of low-back pain and the subjective degree of low-back pain. According to the radiographic findings the lumberjacks had statistically more occurrences (62%) of disc degeneration than the referents (50%). No association between length of exposure to felling work and the prevalence of lumbar disc degeneration could be established. The occurrence of osteoarthritis in the hip and knee joints of the lumberjacks was 5 and 3% for the lumberjacks and the referents, respectively.
对226名从事伐木工作平均20年的伐木工进行了腰痛和骨关节炎发病情况的调查。对照组由98名从事轻度体力劳动或办公室工作的人员组成。两组在腰痛的发生率和腰痛的主观程度方面没有统计学上的显著差异。根据影像学检查结果，伐木工椎间盘退变的发生率在统计学上高于对照组（分别为62%和50%）。未能确定伐木工作暴露时间与腰椎间盘退变患病率之间的关联。伐木工髋关节和膝关节骨关节炎的发生率分别为5%和3%，对照组分别为5%和3%。
