The contribution of syndemic conditions to cardiovascular disease risk

Area of Science:

• Public Health
• Cardiovascular Medicine
• Epidemiology

Background:

• Syndemic conditions (low education, childhood maltreatment, depression, HIV, substance use, obesity) are independent cardiovascular risk factors.
• Research on syndemic conditions and cardiovascular risk in high-risk groups is limited.

Purpose of the Study:

• To examine the association between syndemic conditions and cardiovascular risk in a high-risk population.
• To assess cardiovascular risk markers, specifically atherosclerotic plaque and blood pressure, in relation to syndemic conditions.

Main Methods:

• Carotid artery ultrasound was used to assess atherosclerotic plaque in 503 participants.
• Participants included HIV-infected and HIV-uninfected individuals with and without a history of cocaine use.
• Demographic data and syndemic condition prevalence were collected.

Main Results:

• Each syndemic condition independently increased the odds of atherosclerotic plaque by 8% (OR=1.08).
• Each condition was associated with a 9% increase in systolic blood pressure (OR=1.09) and a 10% increase in diastolic blood pressure (OR=1.10).
• These associations were observed in a diverse, high-risk population.

Conclusions:

• Syndemic conditions are significantly associated with increased cardiovascular risk markers in high-risk populations.
• Multilevel interventions and public policy are crucial to address these risks at the community level.
