Lin YH, et al. – This nationally representative cohort study assessed the link between life–course socioeconomic position (SEP) and inflammatory biomarkers [ C–reactive protein (CRP) and interleukin (IL–6)] in older age. Findings demonstrated an association of life–course SEP with the level of CRP and IL–6 in older age and supported that it is predictive of inflammatory markers in older age. A link was obvious, between low SEP in childhood and elevated inflammatory markers in older age. The risk persisted even after the transition from low SEP in childhood to high SEP in older age.
