workers with job stress more likely to suffer from abnormally high levels of LDL cholesterol

Job stress may be tied to the risk of developing dyslipidemia, a disorder that alters the levels of lipids such as cholesterol or fat in the blood, a new study has warned.

Previous research has shown that emotional stress is linked to the risk of suffering cardiovascular disease as a result of unhealthy habits such as smoking, an unsuitable diet or leading a sedentary lifestyle, among other factors.

Now, the study conducted by the Sociedad de Prevencion de Ibermutuamur, in collaboration with experts from the Virgen de la Victoria Hospital (Malaga) and the Santiago de Compostela University, analyses the relationship between job stress and different parameters associated with how fatty acids are metabolised in the body.

The study was conducted on a sample population of more than 90,000 workers undergoing medical check-ups.

"The workers who stated that they had experienced difficulties in dealing with their job during the previous twelve months (8.7 per cent of the sample) had a higher risk of suffering from dyslipidemia," Carlos Catalina, clinical psychologist and an expert in work-related stress, told Science News and Information Service (SINC).

Dyslipidemia is a lipoproteins' metabolic disorder that can manifest itself in an increase in total cholesterol, low-density lipoproteins (LDLs) and triglyceride levels, in addition to a drop in high-density lipoproteins (HDLs).

Specifically, in the study the workers with job stress were more likely to suffer from abnormally high levels of LDL cholesterol (the so-called 'bad' cholesterol), excessively low levels of HDL cholesterol (the 'good' cholesterol) and positive atherogenic indices, ie potential artery blockage.

"One of the mechanisms that could explain the relationship between stress and cardiovascular risk could be the changes in our lipid profile, which means higher rates of atheromatous plaque accumulation (lipids deposit) in our arteries," Catalina concluded.

The study was published in the Scandinavian Journal of Public Health.
