Objectives. Motor vehicle repair workers are a vulnerable group for developing occupational dermatoses. They are exposed to a wide range of chemical, physical and mechanical hazards. This study aimed to assess the prevalence of occupational dermatoses among motor vehicle repair workers and their risk factors, and to evaluate the effect of a health educational program. Methods. The study was conducted among 106 motor vehicle repair workers. All participants were personally interviewed at their workshops and were subjected to the Nordic occupational skin questionnaire, dermal exposure knowledge, attitudes and perceptions questionnaire, dermatological examination and health educational program. Then, evaluation of the effects of health the program was done after 2 months. Results. Exclusively occupational dermatoses (18.9%) were followed by work-related dermatoses (17.9%). Chronic contact dermatitis was the most frequent exclusively occupational dermatoses (12.26%), followed by tar/oil acneform rash (3.77%) and mechanical injury (3.77%). Xerosis (6.6%) and hyperpigmentation (4.71%) were the most frequent work-related dermatoses. Lack of use of personal protective equipment, older age, longer duration of work, exposure to chemical hazards and car mechanics were the independent risk factors. Conclusions. A significant improvement occurred in the participants’ knowledge about dermal exposure, behavioral action for prevention and overall belief (pre/post intervention) (p < 0.01).

目标。机动车修理工是职业性皮肤病的易感人群。他们暴露在范围广泛的化学、物理和机械危险中。本研究旨在评估机动车维修工人职业性皮肤病的患病率及其危险因素，并评估健康教育计划的效果。方法。这项研究是在 106 名机动车维修工人中进行的。所有参与者都在他们的车间进行了个人访谈，并接受了北欧职业皮肤问卷、皮肤接触知识、态度和感知问卷、皮肤病学检查和健康教育计划。然后，在 2 个月后评估该计划的健康效果。结果。仅职业性皮肤病 (18.9%) 其次是与工作相关的皮肤病 (17.9%)。慢性接触性皮炎是最常见的纯职业性皮肤病 (12.26%)，其次是焦油/油性痤疮样皮疹 (3.77%) 和机械损伤 (3.77%)。干燥症 (6.6%) 和色素沉着过度 (4.71%) 是最常见的与工作有关的皮肤病。未使用个人防护设备、年龄较大、工作时间较长、接触化学品危害和汽车修理工是独立的危险因素。结论。参与者对皮肤接触、预防行为和整体信念（干预前/后）的了解有了显着改善 ( p  < 0.01)。
