Abstract

ACPRs of leukopenia in peripheral blood of workers exposed to benzene in small-scale industries are calculated using capture-recapture methods. The results from two figures with 6-month apart demonstrate that the ACPR in workers exposed to benzene is 36.81(29.14-44)%, significantly higher than that of control 12.71(7.20-18.22)% (P < 0.05), with a relative risk of 2.9. The prevalences of 4 cross-sectional investigations in exposure group calculated with routine method are 18.73%, 26.37%, 27.93%, and 36.76% respectively; in controls, 8.38%, 6.85%, 7.94%, and 15.00% respectively and all fall in the range of 95% CI of ACPR. It is suggested that the methods of calculating ACPR by capture-recapture methods is simple, feasible and efficient, with the results more precise than with traditional methods.

摘要

采用捕获-再捕获法计算小型工业中接触苯工人外周血白细胞减少症的实际患病率（ACPR）。相隔6个月的两个数据结果表明，接触苯工人的ACPR为36.81（29.14 - 44）%，显著高于对照组的12.71（7.20 - 18.22）%（P < 0.05），相对风险为2.9。用常规方法计算的暴露组4次横断面调查患病率分别为18.73%、26.37%、27.93%和36.76%；对照组分别为8.38%、6.85%、7.94%和15.00%，均落在ACPR的95%可信区间范围内。提示采用捕获-再捕获法计算ACPR的方法简单、可行、高效，结果比传统方法更精确。
