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.
蠕形螨是一种生活在人类毛囊中的螨虫。在某些条件下，它们可以迅速繁殖，并通过引起皮肤疾病开始刺激皮肤。本研究旨在探讨工作环境条件是否会影响蠕形螨的流行。这是一项横断面、多中心研究，涉及三个不同的职业群体：矿工、纺织和食品厂工人（n=102）。我们从三个不同的城市的皮肤科门诊招募了患有皮肤病的、确定行业的工人，并将其纳入研究。通过皮肤镜检查来确定蠕形螨的阳性率。使用卡方分析和 T 检验来比较组间的分类变量差异，使用 T 检验来比较组间的连续变量差异。矿工中 50%的蠕形螨阳性率，食品厂工人中 45.3%，纺织工人中 66.7%。所有三个职业群体的蠕形螨阳性率都很高。虽然纺织工人的阳性率最高，但组间差异无统计学意义（p=0.320）。总体而言，女性工人的蠕形螨阳性率明显高于男性工人（p=0.029）。工人在工作环境中接触到各种因素，如纺织厂，而女性对外界因素更敏感，这可能导致这些群体中的蠕形螨患病率更高。因此，改变工作环境或使用合适的防护设备可能有助于治疗由蠕形螨引起的疾病。但是，需要进一步进行更大规模和更多样化的行业群体研究，以得出更确定的观点。
