High incidences of silicosis are continuing to be reported among the agate workers of small-scale household agate processing units in the Khambhat region of Gujarat (India). The objective of this study was to investigate reasons behind the high prevalence of silicosis, and factors affecting the noncompliance with preventive methods among agate workers.
The study was conducted using a questionnaire-based structured interview method among 82 agate workers in Khambhat to assess their awareness level about silicosis and preventive methods, existing morbidity, worker's attitude toward health, and the prevalence of actual use of preventive methods to avoid silica exposure.
The majority of the workers (55%) were aware of silicosis and the harmful effects of silica dust exposure (72%) and knew about simple preventive methods to avoid silica dust exposure (80%), but only a minority of the workers (22%) were actually using the simple and available dust-preventive methods. Only 9% of the uneducated workers were using the preventive methods, while usage was higher among educated workers (28%), who had five or more years of schooling, and these workers had fewer health conditions or less morbidity. Gender and job duration had no effect on the usage of dust-preventive methods.
The data suggest that noncompliance with use of dust-preventive methods could be the reason behind the higher prevalence of silicosis and health morbidity in agate workers, and that years of schooling plays a significant role in the increased usage and self-compliance with dust-preventive methods among agate workers.
古吉拉特邦坎布哈特地区小型家庭玛瑙加工单位的玛瑙工人中,矽肺的发病率持续居高不下。本研究旨在探讨矽肺高发的原因,以及影响玛瑙工人不遵守预防措施的因素。
本研究采用基于问卷的结构化访谈方法,在坎布哈特对 82 名玛瑙工人进行调查,评估他们对矽肺和预防方法的认识水平、现患率、工人对健康的态度以及实际使用预防方法避免接触二氧化硅的情况。
大多数工人(55%)了解矽肺和接触二氧化硅粉尘的有害影响(72%),并了解避免接触二氧化硅粉尘的简单预防方法(80%),但只有少数工人(22%)实际使用简单有效的防尘措施。只有 9%的未受教育的工人使用预防措施,而受教育程度较高(28%)、有五年或五年以上学历的工人使用这些措施的比例更高,这些工人的健康状况或发病情况较少。性别和工作年限对防尘措施的使用没有影响。
数据表明,不遵守使用防尘措施可能是玛瑙工人矽肺和健康发病较高的原因,而受教育年限在增加防尘措施的使用和自我遵守方面起着重要作用。
