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.

教育和社会支持对非裔美国人血压的交互影响


背景 本研究探讨了接受和提供的社会支持对血压 (BP) 的影响是否会因教育程度而异。方法 使用多元线性回归分析参加巴尔的摩黑人衰老研究——认知衰老模式的 602 名非裔美国成年人（48-95 岁）的数据。结果我们发现接受和提供的社会支持对血压没有主要影响。然而，观察到收缩压存在显着的调节效应，即在教育水平较低的个体中，接受的社会支持越大，收缩压越高，并调整了年龄、性别、慢性健康状况和抑郁症状。结论 研究结果表明，社会支持和教育对血压有共同影响，这凸显了考虑不良心血管健康结果的社会心理决定因素的重要性，这些因素对非裔美国人的影响尤为严重。
