The cumulative effects of socioeconomic position (SEP) on cardiovascular disease have been described, but the pathways are unclear. In this study, the authors examined the effects of life-course SEP on inflammatory and hemostatic markers: fibrinogen, C-reactive protein, von Willebrand factor antigen, and tissue plasminogen activator antigen. Data from the 1958 British birth cohort, including data on persons who underwent a biomedical follow-up in 2002–2004, were used. Social class was determined at three stages of respondents' lives: childhood (birth), early adulthood (age 23 years), and midlife (age 42 years). A cumulative indicator score of SEP was calculated that ranged from 0 (always in the highest social class) to 9 (always in the lowest social class). In men and women, associations were observed between cumulative indicator score and fibrinogen (p < 0.001), C-reactive protein (p < 0.001), von Willebrand factor antigen (p 
0.05), and tissue plasminogen activator antigen (p < 0.001 only in women). The trends in fibrinogen and C-reactive protein remained after adjustment for body mass index, smoking, and physical activity. However, the trends became nonsignificant for von Willebrand factor antigen and tissue plasminogen activator antigen in women. Risk exposure related to SEP accumulates across the life course and contributes to raised levels of fibrinogen and C-reactive protein, while childhood SEP influences hemostatic markers more than does adult SEP.
