Purpose. Basing on the studies of hygienic work conditions and the biological age of workers of "noisy professions" at the plants "Obolon" and "Rosinka" to assess aging rates and the effect of the production noise on the biological age of workers and to develop appropriate health recommendations.
Materials and methods. The paper presents a hygienic evaluation of noise, microclimate and lighting at work places of operators, engaged in bottling non-alcoholic and low-alcoholic beverages. The following devices have been used: audiometer "Larson Davis 800 B", ball thermometer "Tensor 41", ball catathermometer (F 64), luxmeter of "U-116" type. The study of the biological age (BA) was conducted in three groups. The first group included employees of the "Obolon" plant (75 workers of "noisy" professions; the second group – workers of the "Rosinka" plant (27 workers of "noisy" professions; the third was a control group (54 persons not exposed to noise). The biological age was defined by a method, developed by the Kyiv Scientificresearch institute of Gerontology for using in outpatient departments and in production conditions.
Results. It is established that according to the "Hygienic Classification of labour…", approved by the Order of the Ministry of Health of Ukraine of 08.04.2014 No. 248, work conditions of operators, engaged in bottling in shops of the plants "Obolon" and "Rosinka" can be referred the Classes 3.1 (harmful conditions of the 1st degree) and 3.2 (harmful conditions of the 2nd degree), by indices of the air temperature – to Classes 2 (permissible), 3.1 (harmful conditions of the 1st degree) and 3.2 (harmful conditions of the 2nd degree); by levels of natural and artificial light – to Classes 2 (permissible) and 3.1 (harmful conditions of the 1st degree). In general, work conditions of operators, engaged in the beverage bottling, can be referred the Class 3.2 (harmful conditions of the 2nd degree).
The study revealed accelerated aging rates in workers of "noisy professions". The mean index "appropriate biological age" – "biological age" in the groups of employees of "noisy professions" at "Obolon" and "Rosinka" plants is statistically significantly higher than that of the control group (9,44 ± 1,97), (5,18 ± 1,91) та (0,25 ± 0,92) years respectively).
Conclusion. The workers of the "noisy professions" at "Obolon" and "Rosinka" plants, exposed to elevated levels of constant, broadband noise, exceeding the threshold limit values at mean and high frequencies (500–8000 Hz), showed the significant (P < 0,05) accelerating aging rates. This can be explained by non-specific noise influence on the human body.
Key words: workers of "noisy professions", biological age, accelerated aging
