Tile setters in construction industries are exposed to a potent risk of silicosis as they are constantly exposed to crystalline silica dust during concrete finishing, cutting and fixing of the ceramic tiles. The noise produced by instruments used in tile settings may lead to noise-induced hearing loss. Noise above the permissible limit of 85 dB may lead to autonomic changes and alteration in blood pressure. These facts gave us an impetus to evaluate the pulmonary functions, blood pressure and hearing deterioration in tile setters and correlate these parameters for their present functional status with duration of exposure to tile cutting profession.
The pulmonary functions were evaluated with spirometer, autonomic status by recording the blood pressure and hearing loss by calculating the Hearing Deterioration Index (HDI) for hearing loss.
There was significant decline in forced vital capacity (FVC), forced expiratory volume 1 sec (FEV1) and forced expiratory volume 1% (FEV1%) in tile setters. The decline in FVC, FEV1 and FEV1% was significantly higher in subjects with exposure of more than five years. There was increased systolic and diastolic blood pressure in those having more than five years of exposure in the tile setting profession as compared to less than five years. There was a positive correlation between years of service in the tile setting profession as well as sound exposure level with HDI and blood pressure in our subjects.
Prolonged exposure to the tile setting profession may lead to compromised lung function, hypertension and hearing deterioration in tile setters.
建筑行业的瓷砖铺设工人面临矽肺病的巨大风险，因为他们在混凝土修整、瓷砖切割和安装过程中持续接触结晶二氧化硅粉尘。瓷砖铺设过程中使用的工具产生的噪音可能导致噪声性听力损失。超过85分贝允许限值的噪音可能导致自主神经变化和血压改变。这些事实促使我们评估瓷砖铺设工人的肺功能、血压和听力衰退情况，并将这些参数与他们目前的功能状态以及瓷砖切割职业的接触时长相关联。
用肺活量计评估肺功能，通过记录血压评估自主神经状态，通过计算听力衰退指数（HDI）评估听力损失。
瓷砖铺设工人的用力肺活量（FVC）、第1秒用力呼气量（FEV1）和第1秒用力呼气容积百分比（FEV1%）显著下降。接触超过五年的受试者中，FVC、FEV1和FEV1%的下降明显更高。与接触少于五年的人相比，从事瓷砖铺设职业超过五年的人收缩压和舒张压升高。在我们的受试者中，瓷砖铺设职业的服务年限以及声音暴露水平与HDI和血压之间存在正相关。
长期从事瓷砖铺设职业可能导致瓷砖铺设工人肺功能受损、高血压和听力衰退。
