Comparative analysis of the parameters of carbohydrate exchange and thiamine security in the crew personnel of the northern water basin depending on the specifics of work, age and professional experience

Purpose: assessment of carbohydrate metabolism and thiamine supply in the crew, depending on the specifics of work, age and professional experience.
Materials and methods. The researchers examined the crew personnel of the Northern Water Basin (river workers, fishermen and seafarers) aged from 21 to 59 years, with professional experience up to 35 years. In the blood serum, the parameters of carbohydrate metabolism were determined by the spectrophotometric method, and in the blood hemolysate, by the fluorometric method, the content of the thiamine in the body.
Results and its discussion. Seafarers have an increased glucose concentration against the background of low thiamine content relative to fishermen and river workers. The frequency of occurrence of marginal states increases with increasing age and experience in river workers, and the frequency of occurrence of pronounced thiamine-deficient states increases with increasing experience in fishermen. Changes in carbohydrate metabolism and thiamine content of the crew depend mainly on the specifics of the work.
