To examine associations between short-term exposure to ambient air pollution and circulating biomarkers of systemic inflammation in participants from the Framingham Offspring and Third Generation cohorts in the Greater Boston area. We included 3,996 non-current smoking participants (mean age 53.6 years, 54% women) who lived within 50 km from a central air pollution monitoring site in Boston, Massachusetts, and calculated the 1- to 7-day moving averages of fine particulate matter (PM2.5), black carbon (BC), sulfate, nitrogen oxides (NOx), and ozone prior to the examination visits. We used linear mixed effects models for C-reactive protein (CRP) and tumor necrosis factor receptor 2 (TNFR2) which were measured up to twice for each participant; we used linear regression models for interleukin-6, fibrinogen, and tumor necrosis factor α (TNFα) which were measured once. We adjusted for demographics, socioeconomic position, lifestyle, time, and weather. The 3- to 7-day moving averages of PM2.5 and sulfate were positively associated with CRP concentrations. A 5 μg/m3 higher 5-day moving average PM2.5 was associated with 4.2% (95% CI: 0.8, 7.6) higher circulating CRP. Positive associations were also observed for NOx with interleukin-6, and for BC, sulfate, and ozone with TNFR2. However, BC, sulfate, and NOx were negatively associated with fibrinogen, and sulfate was negatively associated with TNFα. Higher short-term exposure to relatively low levels of ambient air pollution was associated with higher levels of CRP, interleukin-6, and TNFR2, but not fibrinogen or TNFα, in individuals residing in the Greater Boston area.
