目的探讨从业人员体检人群中肺结核的发病情况及逐年变化趋势。方法对近十年来27.388万体检者X线检查结果进行回顾性分析。结果2005年肺结核检出率达21.5/万，次年下降到5.52/万，两年检出率比较差异有统计学意义(<0.001)，肺结核平均检出率8.95/万。肺结核患者主要集中在20~34岁年龄段(61.2%)，其次为35~59岁年龄段(35.9%)，20岁以下以及60岁以上患者比例较低。结论食品及公共场所从业体检人群中X线透视肺结核检出率较高，X线检查要尽可能早期发现，减少漏诊。“,”Objective To investigate the incidence of pulmonary tuberculosis and change trend of years in the population of jobholders in physical examination. Methods X-ray results of 2738800 subjects for the past ten years were retrospectively analyzed. Results In 2005 year, the detection rate of pulmonary tuberculosis was 21.5/mil ion, it dropped to 5.52/ mil ion in the fol owing year, the detection rate between two years had a significant dif erence ( <0.001), the average detection rate was 8.95/mil ion. Pulmonary tuberculosis mainly concentrated in 20~34 years of age (61.2%), fol owed by 35~59 years of age (35.9%), the proportion of 20 years of age and over 60 years old was low. Conclusion X-ray detection rate for tuberculosis is relatively high in jobholders in physical examination;it should be discovery as early as possible by X-ray examination to reduce missed diagnosis.
