The Role of Psychological Health in Cardiovascular Health: A Racial Comparison.

Area of Science:

• Cardiology
• Psychology
• Public Health

Background:

• Modifiable health factors contribute to racial disparities in cardiovascular health (CVH).
• The specific role of psychological health in these disparities is not well understood.
• Understanding these links is crucial for addressing health inequities.

Purpose of the Study:

• To examine the association between psychological health measures and cardiovascular health (CVH).
• To investigate racial differences in these associations among US adults.
• To determine if psychological health explains Black-White disparities in CVH.

Main Methods:

• Utilized data from the MIDUS biomarker substudy (n=1255) and MIDUS parent study (N=4702).
• Assessed negative psychological factors (e.g., pessimism, anxiety) and positive factors (e.g., well-being, optimism).
• Operationalized cardiovascular health using the American Heart Association's Life's Essential 8 (LE8) score.

Main Results:

• Most negative psychological health factors were negatively associated with LE8 scores and behavior subscores.
• Pessimism showed significant Black-White differences, with higher levels in Black adults.
• Positive factors like psychological well-being, gratitude, and optimism also showed significant Black-White differences, favoring Black adults.

Conclusions:

• Psychological health differences do not substantially explain the observed Black-White disparities in cardiovascular health (CVH).
• While racial differences exist in psychological health and its association with CVH, they are not the primary drivers of overall CVH disparities.
• Further research is needed to identify other key factors contributing to these health inequities.
