[Nutritional status of workers with different levels of work capacity].

Workers aged 30-39 years engaged in the instrument-making industry were followed up during spring season. Their energy expenditure, actual nutrition and providing with vitamins were studied. The data obtained were correlated with the level of their total physical working capacity (TPWC). A significant imbalance in their rations was revealed with respect to the main food substances, trace elements and vitamins. The biochemical investigations disclosed their insufficient providing with ascorbic acid, thiamine, riboflavin. The women workers with high TPWC received in their rations higher content of phosphor and iron and lower levels of calcium, as compared to those with low TPWC. Vitamin deficiency in persons with low TPWC was more pronounced than in workers with high TPWC.
