Insights
Hostility may increase cardiovascular disease risk more in young African Americans than Whites. This study examined hostility and cardiovascular risk factors across racial groups.
Area of Science:
- Psychology
- Cardiovascular Health
- Health Disparities
Background:
- Hostility is linked to cardiovascular disease (CVD) risk.
- Racial disparities in CVD exist, potentially influenced by hostility.
- Understanding these links is crucial for targeted interventions.
Purpose of the Study:
- To explore racial differences in the association between hostility and cardiovascular risk factors.
- To investigate how hostility relates to physiological markers of CVD risk in White and African American young adults.
Main Methods:
- Cook-Medley Hostility (Ho) scores and 11 cardiovascular risk factors were assessed.
- The study included 66 healthy young adults, comprising White and African American participants.
- Statistical analyses controlled for age, gender, and body mass index.
Main Results:
- Hostility interacted with race to affect blood pressure (BP), cardiac index (CI), total peripheral resistance (TPR), insulin (INS), triglycerides (TG), and body fat (PBF).
- Among African Americans, hostility was positively associated with SBP, DBP, TPR, TG, and INS, and negatively with CI.
- Among Whites, hostility was negatively associated with TPR and PBF.
Conclusions:
- Hostility may pose a greater cardiovascular risk to young African Americans compared to Whites.
- These findings highlight the importance of considering race in the context of hostility and cardiovascular risk.
Objective:
Hostility may influence racial disparities in cardiovascular disease through differential associations with cardiovascular risk factors. This study explored racial variations in relations between hostility and selected cardiovascular risk factors.
Methods:
Cook-Medley Hostility (Ho) scores and 11 risk factors were examined among 66 healthy, White and African American young adults.
Results:
Controlling for age, gender, and body mass index, the interaction of hostility and race yielded significant (or marginal) associations with resting systolic and diastolic blood pressure (SBP, DBP), cardiac index (CI; i.e. cardiac output adjusted for body size), total peripheral resistance (TPR), insulin (INS), triglycerides (TG) and percent body fat (PBF). Contributing substantial variance, hostility was positively associated with SBP, DBP, TPR, TG and INS, and negatively associated with CI among African Americans. Conversely, hostility was negatively associated with TPR and PBF among Whites.
Conclusion:
Hostility may confer greater cardiovascular risk among young African Americans than Whites.
