Abstract：
Demodex, a type of mite, lives in human hair follicles. They can multiply very quickly in some conditions and then start to irritate the skin by causing skin disorders. This study aims to investigate if working environment conditions affect the prevalence of Demodex. A cross-sectional, multicenter study was conducted with three different occupational groups: mine, textile and food factory workers (n = 102). Determined industry workers who applied to our outpatient dermatology clinics with the complaint of dermatosis in three different cities were included in the study. Demodex positivity was checked by dermoscopy. Differences between categorical variables examined with Chi-square analysis and T test was used to compare continuous variables between groups. 50% Demodex positivity was found in mine workers, 45.3% in food factory workers and 66.7% in textile manufacturing workers. A high rate of Demodex positivity was observed in all three occupational groups. Although the highest positivity rate was observed in textile manufacturing workers, no significant difference was found between the groups (p = 0.320). The overall prevalence of Demodex in female workers was statistically significantly higher than in male workers (p = 0.029). Exposure of workers to a wide variety of factors in work environments such as textile factories and the fact that women are more sensitive to external factors may have caused the prevalence of Demodex to be higher in these groups. So, a change in the work environment or the use of suitable protective equipment may benefit the treatment of diseases caused by Demodex. But, further studies are needed with larger and various industry groups to make more certain views.
摘要：
蠕形螨,一种螨虫,生活在人类毛囊中。在某些情况下，它们可以迅速繁殖，然后通过引起皮肤疾病开始刺激皮肤。这项研究旨在调查工作环境条件是否会影响蠕形螨的患病率。横截面，多中心研究是对三个不同的职业群体进行的：矿山，纺织和食品厂工人(n=102)。这项研究包括了在三个不同城市向我们的门诊皮肤科诊所申请皮肤病的坚定行业工人。通过皮肤镜检查蠕形螨阳性。使用卡方分析和T检验检查的分类变量之间的差异来比较组间的连续变量。在矿山工人中发现了50％的蠕形螨阳性，食品厂工人占45.3%，纺织制造业工人占66.7%。在所有三个职业组中都观察到了很高的蠕形螨阳性率。尽管在纺织制造工人中观察到最高的阳性率，两组间无显著差异(p=0.320).女性工人蠕形螨的总体患病率在统计学上显着高于男性工人（p=0.029）。工人在纺织工厂等工作环境中暴露于各种各样的因素，以及妇女对外部因素更敏感的事实，可能导致这些群体中蠕形螨的患病率更高。所以,改变工作环境或使用合适的防护设备可能有利于治疗蠕形螨引起的疾病。但是,需要与更大和更多的行业团体进行进一步研究，以提出更确定的观点。
