activity. An inverse association between physical activity and inflammation has been demonstrated, but no long-term
prospective data are available. We therefore examined the association between physical activity and inflammatory
markers over a 10-year follow-up period.
Methods and Results—Participants were 4289 men and women (mean age, 49.2 years) from the Whitehall II cohort study.
Self-reported physical activity and inflammatory markers (serum high-sensitivity C-reactive protein and interleukin-6)
were measured at baseline (1991) and follow-up (2002). Forty-nine percent of the participants adhered to standard
physical activity recommendations for cardiovascular health (2.5 h/wk moderate to vigorous physical activity) across all
assessments. Physically active participants at baseline had lower C-reactive protein and interleukin-6 levels, and this
difference remained stable over time. Compared with participants who rarely adhered to physical activity guidelines
over the 10-year follow-up, the high-adherence group displayed lower loge C-reactive protein ( 0.07; 95%
confidence interval, 0.12 to 0.02) and loge interleukin-6 ( 0.07; 95% confidence interval, 0.10 to 0.03) at
follow-up after adjustment for a range of covariates. Compared with participants who remained stable, those who
reported an increase in physical activity of at least 2.5 h/wk displayed lower loge C-reactive protein ( coefficient
0.05; 95% confidence interval, 0.10 to 0.001) and loge interleukin-6 ( coefficient 0.06; 95%
confidence interval, 0.09 to 0.03) at follow-up.
Conclusions—Regular physical activity is associated with lower markers of inflammation over 10 years of follow-up and
thus may be important in preventing the proinflammatory state seen with aging.
