Key result
Greater social support is linked to higher SBP among African Americans with low education.
Why the study?
It was unknown whether the effects of received and provided social support on blood pressure differ by education level.
Do the effects of received and provided social support on blood pressure differ by education level in African American adults?

Do the effects of received and provided social support on blood pressure differ by education level in African American adults?
Social support and education have joint interactive effects on systolic blood pressure in African Americans, highlighting the complex role of psychosocial determinants in cardiovascular health.
May warrant caution interpreting support benefits in low-education African Americans; leaves open education as modifier of support-BP associations.
BACKGROUND: This study examined whether the effects of received and provided social support on blood pressure (BP) would differ by education. METHODS: Data from 602 African American adults (48-95 years) enrolled in the Baltimore Study of Black Aging-Patterns of Cognitive Aging were analyzed using multiple linear regression. RESULTS: We found no main effects of received and provided social support on BP. However, a significant moderation effect was observed for systolic BP, such that greater received social support was positively associated with higher systolic BP among individuals with low levels of education, adjusting for age, sex, chronic health conditions, and depressive symptoms. CONCLUSIONS: The findings demonstrate that social support and education have joint effects on BP, which highlights the importance of considering psychosocial determinants of adverse cardiovascular health outcomes that disproportionately affect African Americans.

Byrd et al. (2021) conducted an observational in Blood pressure (n=602). Social support and education was evaluated on Blood pressure. Greater received social support was positively associated with higher systolic blood pressure among African American adults with low levels of education.
