选择本市某制药厂工人连续两年健康监护资料,应用俘获再俘获法,计算其外周血白细胞降低者的总估校正现患率(ACPR)。结果:接触组为45.27％(32.40％～57.99％),对照组为21.78％(5.44％～37.62％),两组有非常显著性差异(P<0.01),相对危险度为1.94。用常规法计算两年检出率分别为接触组16.08％,20.14％,对照组7.20％,11.67％,虽在ACPR95％可信限内,但低于ACPR值。制药行业职工白细胞降低者ACPR高于苯作业者,两组有显著性差异(P<0.05)。ACPR计算方法简便,结果准确,可用于健康监护资料的统计分析。
Select a city pharmaceutical workers health care information for two consecutive years, the use of capture and re-capture method to calculate the total estimated corrected positive peripheral blood leukopenia (ACPR). Results: The contact group was 45.27% (32.40% -57.99%) and the control group was 21.78% (5.44% -37.62%). There was a significant difference between the two groups (P <0.01). The relative risk was 1.94. The two-year detection rate of conventional method was 16.08% and 20.14% in the exposure group and 7.20% and 11.67% in the control group, respectively, although within the 95% confidence level of ACPR, it was lower than the ACPR value. Workers in the pharmaceutical industry leukopenia ACPR higher than benzene workers, the two groups were significantly different (P <0.05). ACPR calculation method is simple, accurate and can be used for statistical analysis of health care data.
