Consistent findings about the inverse association of social network level with coronary heart disease mortality and morbidity suggest the importance of investigating biological pathways of association.
Differences in plasma fibrinogen level were investigated among middle-aged men with weak and strong structural and functional social network ties.
Men with low scores in the adequacy of social participation variable (structural) had higher mean values of plasma fibrinogen than those with high scores.
The difference remained after adjustment for age, smoking and cardiovascular health status and after possible modifying factors were taken into account, but did not remain significant after allowing for physical fitness.
Men with high scores in overall support (functional) had higher plasma fibrinogen levels compared to the men with low scores.
This difference persisted after age and cardiovascular health status were taken into account but was explained by smoking.
The data suggest that smoking and cardiorespiratory fitness are important mediating or modifying factors between structural and functional aspects of social network ties and plasma fibrinogen.
