基于巴西巴伊亚州制造业工人2000-2009年的体检数据，发现白细胞减少症患病率为19.09%，且呈下降趋势，可能反映了苯国家协议对工人健康的积极影响。
<h3>Objectives</h3> To estimate the prevalence of leucopenia among industrial workers 2000–2009. <h3>Methods</h3> The study population comprises workers from manufacturing industries of the Bahia State, Brazil, who had annual compulsory medical checkups in a national not-for-profit occupational safety and health care system during the study period. We retrieved computerised medical records, clinical and laboratory exams, and also workplace risk assessment, occupational and socio-demographic data. Leucopenia was defined as having leucocytes counting less than 4000. <h3></h3> <h3>Results</h3> From a total of 64 454 workers with valid blood counting data, 12 303 (19.09%) had leucopenia over the study time. Prevalence of leucopenia was 21.87% in 2005, 20.73% in 2006 showing a declining trend until 2009 when reached 15.89% (p < 0.001). Leucopenia was higher among male workers than women (p < 0.001) and in the rubber and plastic industry. <h3></h3> <h3>Conclusions</h3> Blood cell counting is compusory monitored in industry, by data are rarely analysed and results made public. Preliminary results of our analysis show that there is a declining trend of leucopenia prevalence suggesting a possible positive impact of the Benzene National Agreement on workers’ health in the rubber and plastic industry in Bahia.
