Association of negative and positive social ties with fibrinogen levels in young women.

Abstract

The associations between positive and negative aspects of social relationships and fibrinogen, a risk factor for coronary heart disease (CHD), were examined in young, healthy women recruited from the community (n = 46) and from a college campus (n = 42). For community women, the perception that individuals in their social networks frequently undermined them was related to higher fibrinogen, independent of perceived frequency of support. For college women, fibrinogen was elevated among women with frequent undermining only when they also reported infrequent support. After controlling for other risk factors, the associations between social ties and fibrinogen remained significant in both samples. These results indicate that positive and negative social ties are associated with fibrinogen levels and suggest that social relationships may affect CHD risk in part through their influence on fibrinogen.
