Background: Although the quality of one’s social relationships has been linked to important physical health outcomes, less work has been conducted examining family and friends that differ in their underlying positivity and negativity. Purpose: The main aim of this study was to examine the association between supportive, aversive, and ambivalent family/friends with levels of C-reactive proteins. Methods: Three hundred participants from the North Texas Heart Study completed the social relationships index and a blood draw to assess high-sensitivity C-reactive proteins (hs-CRPs). Results: After standard controls, the number of supportive family members predicted lower hs-CRP levels, whereas the number of ambivalent family members predicted higher hs-CRP levels. These links were independent of depressive symptoms and perceived stress. Conclusions: These data highlight the importance of considering specific types of relationships and their underlying positive and negative aspects in research on social ties and physical health.
