There is a high prevalence of silicosis and other morbid conditions leading to early death among agate workers at Khambhat of Gujarat.
The present study describes the prevalence of X-ray positive silicosis in a sample of a high-risk group visiting a clinic at Shakarpur of Khambhat.
A cross-sectional study among 123 clinically suspected cases was conducted over 6 months.
A chest physician and a radiologist independently evaluated the Chest X-rays of 123 clinically suspected patients of silicosis. Silicosis was confirmed if either of them rated the X-ray as positive.
Descriptive statistics and logistic regression were done using SPSS software version 14.
Out of 123 cases, 85 (69.1%) were confirmed as silicosis. There was no significant difference in the prevalence between males (70.3%) and females (69.4%). Workers with more than 10 years of exposure to silica had an odd ratio of 4.8, 95% CI (1.76, 13.60) compared to those with less than 10 years of exposure. A logistic regression analysis showed that for every extra year of exposure, the odds of getting silicosis increased by about 12%.
This study highlights the catastrophic effects of exposures to silica in agate worker, which calls for urgent protective measures for this population.
古吉拉特邦坎贝的玛瑙工人中，矽肺病和其他导致过早死亡的疾病患病率很高。
本研究描述了在坎贝沙卡尔布尔一家诊所就诊的高危人群样本中X线阳性矽肺病的患病率。
对123例临床疑似病例进行了为期6个月的横断面研究。
一名胸科医生和一名放射科医生独立评估了123例临床疑似矽肺病患者的胸部X光片。如果他们中的任何一人将X光片评为阳性，则确诊为矽肺病。
使用SPSS 14.0软件进行描述性统计和逻辑回归分析。
123例病例中，85例（69.1%）确诊为矽肺病。男性（70.3%）和女性（69.4%）的患病率无显著差异。与接触二氧化硅少于10年的工人相比，接触二氧化硅超过10年的工人的优势比为4.8，95%可信区间为（1.76，13.60）。逻辑回归分析表明，每多接触一年，患矽肺病的几率增加约12%。
本研究强调了玛瑙工人接触二氧化硅的灾难性影响，这就要求对这一人群采取紧急保护措施。
