The stone-grinding industry is well known to place its workforce at higher risk for silicosis. In addition, workers who are exposed to silica fibers are at a higher risk for pulmonary tuberculosis. This study was conducted to determine the prevalence levels of silicosis and pulmonary tuberculosis among workers in 33 factories in 3 subdistricts of Saraburi, Thailand and the associated risk factors. Thirty-one of the factories (93.9%) had amounts of either total dust or respirable dust exceeding threshold limit values with the average levels of total dust and respirable dust of 24.3 +/- 34.6 and 2.4 +/- 1.6 mg/m3 respectively. Radiologic patterns indicated that 61 workers (9.0%) had silicosis and 13 workers (1.9%) had pulmonary tuberculosis. The prevalence of silicosis and pulmonary tuberculosis was significantly associated with years of work. This study demonstrated the need for developing and supporting potential primary preventive intervention, periodic medical screening as a part of a medical surveillance system and a national occupational medical services program.
众所周知，磨石行业的工人患矽肺病的风险更高。此外，接触硅纤维的工人患肺结核的风险更高。本研究旨在确定泰国沙拉武里3个分区33家工厂工人中矽肺病和肺结核的患病率水平以及相关风险因素。其中31家工厂（93.9%）的总粉尘或可吸入粉尘量超过阈值，总粉尘和可吸入粉尘的平均水平分别为24.3±34.6和2.4±1.6毫克/立方米。放射学检查结果显示，61名工人（9.0%）患有矽肺病，13名工人（1.9%）患有肺结核。矽肺病和肺结核的患病率与工作年限显著相关。本研究表明，有必要制定和支持潜在的一级预防干预措施、作为医疗监测系统一部分的定期医学筛查以及国家职业医疗服务计划。
