This association may be due to chronic inflammation which is often present in those with reduced lung function. Purpose We investigated the possible role of systemic inflammation as the mediator between lung function and arterial stiffness in 1534 black South Africans. Methods Spirometric data including forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) were obtained. C-reactive protein (CRP), interleukin-6 (IL-6), blood pressure (BP) and carotid-radial pulse wave velocity (PWV) were determined. Results In multivariable-adjusted models, an independent inverse association was found between IL-6 and FEV1 (b = -0.20, p\0.001) and FVC (b = -0.18, p\0.001). Similar results were found for CRP. PWV was inversely associated with FEV1 (b = -0.06, p = 0.037). No association was found between inflammatory markers, BP or PWV. Conclusion Reduced lung function was associated with increased inflammation and arterial stiffness. The lack of association between arterial stiffness and inflammatory markers suggests that inflammation may not be the mediating link between lung and vascular function in this populationenPulmonary functionBlood pressureC-reactive proteinInterleukin-6Arterial stiffnessAfricanArticle
