Correlative factors on prevalence rate of dislipidemia among 1 337 coal miners in Shanxi province

Abstract

Objective: To understand the prevalence rate and correlative factors of dislipidemia among Shanxi coal miners and to provide evidence for the development of programs on dislipidemia prevention. Methods: We investigated 1 337 mine workers from a Coal Group in April 2016 and collected data related to their blood biochemistry. We then classified the types in accordance with the diagnostic criteria of " Guidelines for prevention and treatment of dyslipidemia in Chinese adults (2007)" , using χ(2) test and unconditional logistic regression model for analysis. Results: The overall prevalence rate of Dislipidemia was 59.1% (790/1 337), with males as 60.4% (708/1 173) and females as 50.0%(82/164) while males appeared higher (χ(2)=6.386, P<0.05). Among the 20-34, 35-49, 50 and above year-old groups, the rates were 68.8%, 58.7%, 49.5%, respectively. Results from the χ(2) test showed that gender, age and body mass index were the influencing factors on dislipidemia (χ(2)=7.117, P<0.01; χ(2)=37.135, P<0.01; χ(2)=7.009, P<0.05), while logistic regression analysis showed that sex, age, body mass index level, systolic blood pressure were significantly associated with dislipidemia (P<0.05). Male miners appeared 1.501 times (OR=1.501, 95%CI: 1.895-2.516) higher than female miners in suffering from the risk of dyslipidemia. In different age groups, risks of dyslipidemia in the 35-49, 20-34 year-old groups were 1.672 (OR=1.672, 95%CI: 1.501-2.392) and 2.369 times (OR= 2.369, 95% CI: 1.275-3.469) higher than the 50 year-old. Group that with high BMI, the risk of dyslipidemia was 1.443 times (OR=1.443, 95%CI: 1.139-1.828) higher than the normal BMI group. Group with abnormal systolic pressure was 1.829 times (OR=1.829, 95%CI: 1.152-2.906) higher than normal systolic pressure group. However, diastolic blood pressure, blood sugar, uric acid, and electrocardiogram findings did not seem to show statistically significant meanings on dislipidemia. Conclusion: Among the coal mine workers, those who were males, aged from 20 to 34, having high blood pressure (systolic blood pressure abnormalities) or with high BMI (≥24.0 kg/m(2)) need to be taken special attention on care and prevention of dislipidemia.
