Working conditions and work-related pathologies at enterprises located in Chukotka autonomous area

For many years, morbidity with work-related diseases has been higher in Chukotka Autonomous Area (ChAA) than on average in Russia. Our research objects were working conditions and morbidity with work-related diseases. Our research goal was to examine reasons for work-related pathology occurrence, its structure, and prevalence in ChAA in 2008-2018. We examined data obtained via social-hygienic monitoring in 2008-2018 in Chukotka, paying close attention to a section entitled «Working conditions and work-related pathology». We established that noise (17.4 %) and cooling microclimate (11.8 %) were the most widely spread hazardous occupational factors in ChAA. 20.1 % workers were exposed to a combination of hazardous factors. 13.5 % workers were employed at industrial objects that belonged to the 1st surveillance group (the highest risks); 31.9 % worked at economic entities from the 3rd surveillance group (average risks). In 2008-2018 216 work-related diseases were first diagnosed in Chukotka, mostly among workers employed at mining enterprises (81.5 %). Sensorineural hearing loss / noise effects in the internal ear (35.2 %) and respiratory diseases (31.9 %) prevailed in their structure. 73.6 % diseases were detected due to patients applying for medical aid themselves. In 2008-2015 there was a steady growth in work-related morbidity (from 1.94 to 13.5 per 10,000 workers), but there was a decrease in it in 2016-2018 (down to 5.11 per 10,000 workers) with considerable fluctuations in numbers of first diagnosed diseases. Risks of work-related pathology occurrence were higher in Chukotka in 2018 than in 2008: OR=2.37; CI 1.82-3.09; χ2=43.8; р function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
