Social relationships are widely understood to be important for sustaining and improving health and longevity, but it remains unclear how different dimensions of social relationships operate through similar or distinct mechanisms to affect biophysiological markers of aging-related disease over time.
This study utilized longitudinal data on a nationally representative sample of older adults from the National Social Life, Health, and Aging Project (2005-2011) to examine the prospective associations between social integration and social support and change in systolic blood pressure (SBP) and hypertension risk over time.
Although both social relationship dimensions have significant physiological impacts, their relative importance differs by outcome. Low social support was predictive of increase in SBP, whereas low social integration was predictive of increase in risk of hypertension.
The different roles of relationship characteristics in predicting change in physiological outcomes suggest specific biophysiological stress response and behavioral mechanisms that have important implications for both scientific understandings and effective prevention and control of a leading chronic condition in late life.
社会关系对于维持和改善健康及长寿的重要性已得到广泛认可，但社会关系的不同维度如何通过相似或不同的机制随时间影响衰老相关疾病的生物生理标志物仍不清楚。
本研究利用了来自全国社会生活、健康与老龄化项目（2005 - 2011年）的具有全国代表性的老年人样本的纵向数据，以检验社会融合与社会支持之间的前瞻性关联以及收缩压（SBP）和高血压风险随时间的变化。
尽管社会关系的两个维度都有显著的生理影响，但它们的相对重要性因结果而异。低社会支持可预测SBP升高，而低社会融合可预测高血压风险增加。
关系特征在预测生理结果变化中的不同作用表明了特定的生物生理应激反应和行为机制，这对科学理解以及有效预防和控制晚年的一种主要慢性病具有重要意义。
