[Economic loss due to morbidity with temporary disability in industrial plants in Kazakhstan]

The morbidity resulting in temporary disability (TD) of workers at phosphorus and lead factories of Kazakhstan was studied. Using the coefficient of multiple regression equation, a statistical evaluation of the dependence between changes in morbidity and the trends in the development of factor indications in time was undertaken; based on the study results prognostic estimations were made of temporary disability and economic damage it caused at all phosphorus and lead industrial enterprises of the Republic until the year 2000. It was found that all diseases resulting in TD of workers at both kinds of industrial enterprises could be divided into three groups: those tended to decrease, those tended to increase and those tended to remain stable. The cycles and levels of morbidity resulting in TD not only in those branches of industry as a whole but also in each particular branch were established according to age, occupation, industrial experience of work and the type of workshop. The economic damage to the phosphorus and lead industries of Kazakhstan caused by the morbidity resulting in TD was estimated during the time of the survey along with the projections until the year 2000.
