Analysis and hygienic assessment of 9-year dynamics of morbidity with temporary disability in shipbuilders

Abstract

The authors studied dynamics of transitory disablement morbidity in shipbuilders with small length of service, using annual increase of health risk parameters and comparing these parameters with those in the workers with longer length of service. Over 10 years, the observation covered demographic characteristics, health state (transitory disablement morbidity, medical examination data) and work conditions of workers, specialists and authorities of major shipbuilding enterprise. Overall amount of the observations of transitory disablement morbidity equalled to 15995 human-hours. Annual increase of health risk is the most adequate and necessary criteria in risk-oriented approach to evaluation and forecasting of occupational hazards’ influence on workers’ health. Hazard degree of work conditions in workers with 1–4 years of service in higher than that in the same occupation workers with longer length of service. Maximal values of transitory disablement morbidity are seen on 4th year of service. Optimal range of service for transitory disablement morbidity analysis is 1–2 years interval for hazard degree 4, 1–3 years for hazard degree 3, 1–4 years for hazard degree 2, and 1–10 years for hazard degree 1.
