Police work and subclinical atherosclerosis

Area of Science:

• Cardiovascular Disease Research
• Occupational Health
• Medical Imaging

Background:

• Urban police officers face unique occupational stressors.
• Subclinical cardiovascular disease (CVD) is a precursor to clinical events.
• Carotid artery intima-media thickness (IMT) is a validated measure of atherosclerosis.

Purpose of the Study:

• To investigate the association between employment as an urban police officer and subclinical CVD.
• To measure subclinical CVD using carotid artery intima-media thickness (IMT).

Main Methods:

• A comparative study design was employed.
• Participants included urban police officers (n=312) and a general population sample (n=318), all free of clinical CVD.
• Carotid artery intima-media thickness (IMT) was measured to assess atherosclerosis.

Main Results:

• Police officers exhibited elevated levels of traditional CVD risk factors, including blood pressure, total cholesterol, and smoking prevalence.
• After adjusting for age, gender, and traditional risk factors, police officers showed significantly increased mean common carotid IMT (0.67 mm vs. 0.64 mm, P=0.03).
• Police officers also showed a trend towards increased mean maximum carotid IMT (0.99 mm vs. 0.95 mm, P=0.13).

Conclusions:

• Police officers demonstrate increased levels of atherosclerosis compared to a general population sample.
• The observed increase in atherosclerosis was not entirely explained by traditional CVD risk factors.
• These findings suggest that occupational factors inherent to law enforcement may contribute to increased CVD risk through mechanisms beyond established risk factors.
