The investigators examined the potential influence of social support on age-related differences in resting cardiovascular function and the potential mediators responsible for such associations in 67 normotensive women and men. Consistent with prior research, age predicted increased resting systolic blood pressure (SBP) and diastolic blood pressure (DBP). More importantly, regression analyses revealed that social support moderated age-related differences in resting SBP and DBP, as age predicted higher resting blood pressure for individuals low in social support, but was unrelated to blood pressure for individuals high in social support. An examination of potential pathways revealed that these results were not mediated by various health-related variables, personality factors, or psychological processes. Implications for the study of social support and health are discussed.
研究人员在67名血压正常的女性和男性中，考察了社会支持对静息心血管功能的年龄差异的潜在影响，以及造成这种关联的潜在中介因素。与先前的研究一致，年龄预示着静息收缩压（SBP）和舒张压（DBP）升高。更重要的是，回归分析显示，社会支持调节了静息SBP和DBP的年龄差异，因为年龄预示着社会支持水平低的个体静息血压较高，但与社会支持水平高的个体的血压无关。对潜在途径的研究表明，这些结果并非由各种与健康相关的变量、人格因素或心理过程介导。本文讨论了该研究对社会支持与健康研究的意义。
