Abstract:
We aimed to identify the contemporary prevalence of byssinosis through a systematic review. Medline, Web of Science, Embase, and Global Health databases were used to identify studies published in any language between 2000 and 2019, reporting primary data on byssinosis among adults. We used the Joanna Briggs Institute checklist to estimate the risk of bias in studies and undertook a qualitative, narrative data analysis. The review considered the prevalence of byssinosis, chest tightness, and airflow obstruction in textile workers in low- and middle-income countries (LMICs). We found 26 relevant studies that included 6930 workers across 12 countries. Most of the studies (n = 19) were from Asia, and seven from African countries. Twenty-five studies were cross-sectional surveys while one was a cohort study. The prevalence of byssinosis was reported by 18 studies, and ranged from 8% to 38%, without any clear associations, at the group level, between the prevalence of byssinosis and durations of workers\' exposures. Prevalence of chest tightness ranged between 4% and 58% and that of airflow obstruction between 10% and 30%. A strong correlation (r = 0.72) was found between prevalence of byssinosis and cotton dust levels. Our findings indicate that byssinosis remains a significant, contemporary problem in some parts of the textile sector in LMICs.
摘要:
我们的目的是通过系统评价来确定Byssinosis的当代患病率。Medline,WebofScience,Embase,和全球卫生数据库用于确定2000年至2019年期间以任何语言发表的研究,报告了成年人中有关吸虫病的主要数据。我们使用JoannaBriggs研究所检查表来估计研究中的偏倚风险,并进行了定性,叙事数据分析。该综述考虑了byssinosis的患病率,胸闷,以及中低收入国家(LMICs)纺织工人的气流阻塞。我们发现了26项相关研究,其中包括12个国家的6930名工人。大多数研究(n=19)来自亚洲,和七个来自非洲国家。25项研究是横断面调查,而一项是队列研究。18项研究报告了byssinosis的患病率,从8%到38%不等,没有任何明确的联系,在集团层面,byssinosis的患病率和工人暴露持续时间之间的关系。胸闷的患病率在4%至58%之间,气流阻塞的患病率在10%至30%之间。在吸虫病的患病率与棉尘水平之间发现了很强的相关性(r=0.72)。我们的研究结果表明,byssinosis仍然是一个重要的,LMIC纺织部门某些地区的当代问题。
