Structural peculiarities of metabolic syndrome in workers employed at oil extracting enterprise

Our research goal was to establish prevalence and structure of metabolic syndrome in workers employed at an oil-extracting enterprise and peculiarities of a relation between working experience and metabolic syndrome components as well as medical behavior of workers given that there were cardiovascular risk factors. Data and methods. We examined 292 oil and gas extraction operators (test group) who were exposed to adverse industrial factors (chemical factor, noise, labor hardness, and unfavorable microclimate) and 65 office workers employed at the same enterprise (reference group). We determined whether workers had metabolic syndrome components and if yes, which ones (arterial hypertension, abdominal obesity, dyslipidemia, improper glycemia on an empty stomach); we also examined a relation between working experience and probability of these components being detected in a worker. Results. Arterial hypertension syndrome was registered in 44.9% oil and gas extraction operators and in 36.9% office workers (RR=1.22 (95% CI 0.86–1.71)); abdominal obesity was detected in 53.8% workers in the test group and 50.8% office workers from the reference group (RR=1.06 (95% CI 0.82–1.38)); dyslipidemia was registered in 59.6% and in 58.5% workers accordingly (RR=1.02 (95% CI 0.81–1.27)). Carbohydrate metabolism disorders were registered in 18.2% oil and gas extraction operators and in 12.3% office workers (RR=1.45 (95% CI 0.72–2.89)).We detected dependence between probable AH occurrence and working experience in oil and gas extraction operators (b0=-2.5; b1=0.09; F=1,224.3; R2=0.83; р=0.0001) with a significant relation between the disease and working experience under exposure to adverse industrial factors; whereas there was no such dependence detected for office workers from the reference group. Dependency of abdominal obesity, dyslipidemia, and hyperglycemia on working experience was also more significant among oil and gas extraction operators (R2=0.43–0.56; р=0.0001) than among office workers (R2=0.11–0.52; р=0.02–0.0001). There was a greater % of smokers among oil and gas extraction operators, they tended to have higher systolic, diastolic, and pulse arterial pressure. Workers didn’t receive hypotensive and hypolipidemic medications in sufficient number of cases but office workers managed to achieve normal blood pressure 2.5 times more frequently.
