A follow-up Study of vibration-induced White Finger Due to chain-saw Operation
对1956-1980年间日本国有林业工人进行纵向研究，发现链锯使用引起的振动性白指病患病率在1958-1959年队列中最高达62.6%，之后显著下降，并报告了潜伏期和暴露后恢复情况。
A longitudinal study was undertaken to evaluate changes in the prevalence of vibration-induced white finger (VWF) among a population of Japanese state forestry workers during the period 1956-1980. The peak prevalence was 62.6%, determined for the cohort beginning chain-saw use in 1958-1959. Beginning with the 1968-1969 cohort, the prevalence decreased significantly. During the study period the prevalences in this cohort were approximately 10, 20, 30, and 40 % after 2, 4, 7, and 12 years of exposure, respectively. The incidence increased gradually after 1960, and the peak value (5-6 %) was reached in 1966. The latency interval for the development of VWF averaged 6.4 (SD 3.7) years (6000 to 7 000 h). The prevalence of VWF after the end of exposure fell to 50.2 % in the cohort after more than 12 years of observation.
