The article deals with results of assessing risk of occupationally related hypertension among workers of sylvinitedressing works, with individual sensitivity consideration. Epidemiologic study proved correlation between occupational exposure to noise over 83 dB and hypertension and its predictors - increased activity of serum lipoprotein and homocystein. The studies determined an indicator of the workers' increased sensitivity to arterial hypertension development and to changes in parameters of disordered vascular tone regulation (increased activity of serum lipoprotein and homocystein) under exposure to noise - CT genotype of MTHFR gene. Workers with CT genotype of MTHFR gene, according to epidemiologic analysis, demonstrated increase in relative risk of vascular tone regulation disorders (hypertension predictor). Additional probability ofvascular tone regulation disorders under exposure to noise of 83 dB in sylvinitedressing workers with increased individual sensitivity is estimated at 3%.
