THE BONE TISSUE DENSITY IN WORKERS OF CHEMICAL INDUSTRY
The spread of osteopenia and osteoporosis according to bony tissue mineral density has been studied in 442 chemical workers involved in the production of chlororganic compounds of low intencity. For this purpose the method of ultrasound osteodensitometry of bones (lower third of the radius, the hand third finger phalanx, tibia diaphysis middle part) has been used. A decrease in bony tissue mineral density revealed in female and male workers of the manufacturing production in all age groups is more common than in the population selection. Osteoporosis has been detected in 14% of female workers aged 20-29 years, osteopenia - in 60%, in the age group of 30-39 years - in 15%, 40-49 years - in 22% and 55%, 50-59 years - in 43% and 55%, respectively. The pathogenetic mechanisms of an accelerated decrease in bony tissue density are being considered.
