The association between mercury concentrations and lipid profiles in the Korean National Environmental Health Survey (KoNEHS) cycle 3: Soo Ho Sohn, Han Cheol Heo, Seongmin Jo, Chulyong Park, Joon Sakong; Ann Occup Environ Med 2020;32:e19.

Background

High concentrations of mercury intake from seafood are known to cause various side effects in humans, including on the nervous system. Various studies have reported the effects of mercury concentrations in humans; however, the association between dyslipidemia, a cardiovascular disease risk factor, and mercury remains controversial. Therefore, this study aimed to investigate the association between mercury accumulation and cholesterol concentrations in a Korean population.

Methods

We analyzed data of a sample of 3,228 respondents obtained from the Korean National Environmental Health Survey cycle 3, surveyed between 2015 and 2017, to determine how lipid profiles changed according to the blood mercury concentrations (BHg) and urine mercury concentrations (UHg). Multiple regression analysis was used to determine the effects of mercury concentrations among various factors affecting blood cholesterol levels.

Results

The arithmetic mean (AM) of BHg was 2.91 (2.81–3.02) μg/L, and the geometric mean (GM) was 2.71 (2.59–2.85) μg/L. The AM of UHg was 0.52 (0.48–0.56) μg/L, and the GM was 0.35 (0.33–0.38) μg/L. Lipid profiles were more related to the BHg than to the UHg. Total cholesterol (total-C), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels increased significantly as BHg increased in males, and total-C, triglyceride, and LDL-C levels increased significantly in females. Multiple regression analysis indicated that BHg were significantly associated with total-C, HDL-C, and LDL-C levels.

Conclusions

We found an association between mercury exposure and the risk of dyslipidemia; however, further studies are required to elucidate a causal association.

The Relationship between Job Stress and Dyslipidemia in Express Bus Drivers: Nam Soo Lee, Kyung Jae Lee, Joo Ja Kim, Jin Woo Lee; Korean Journal of Occupational and Environmental Medicine 2010;22(3):221-229. Published online September 30, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.3.221

Abstract PDF

OBJECTIVES
To examine whether or not there is a relationship between job stress and dyslipidemia in male express bus drivers.
METHODS
The study subjects were 301 male express bus drivers. The data was obtained from annual health surveillance. A structured questionnaire was used to assess sociodemographics, health-related behaviors and job characteristics. Job stress was measured by the Korean Occupational Stress Scale-Short Form. A measure of blood lipid levels, comprised of total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides, was dichotomized and categorized into 'high' or 'low'. Multiple logistic regression modeling was used to determine an association between job stress and dyslipidemia, with blood lipid level as the dependent variable.
RESULTS
We found that high job demand was associated with high total cholesterol (OR 3.25, 95% CI 1.18-8.95) and high LDL-cholesterol (OR 4.14, 95% CI 1.18-14.44) and lack of job control was associated with low HDL-cholesterol (OR 1.92, 95% CI 1.04-3.56).
CONCLUSION
These results indicate that job demand and lack of job control were associated with dyslipidemia in male express bus drivers. A job stress management program that emphasizes job demand and lack of job control is needed to prevent dyslipidemia in male express bus drivers.
