Objective The aim was to estimate the effects of ponderal index at birth and body mass index (BMI) in early adulthood on C‐reactive protein (CRP) and interleukin‐6 (IL‐6) and to quantify the effects through subsequent measures of body size. In a subanalysis, the contributions of maternal BMI to the inflammatory status of offspring were investigated. Methods The study was based on 2,986 Danish males from the Copenhagen Aging and Midlife Biobank. Path analysis was employed to estimate direct and indirect effects. Results A 10% higher maternal BMI was associated with 7% higher CRP and 3% higher IL‐6 among offspring. A 10% higher ponderal index at birth was associated with 4% lower CRP in late midlife; this effect was only partially mediated by later growth. A 10% higher BMI in early adulthood was associated with 8% higher CRP and 4% higher IL‐6 in late midlife. The findings suggest that weight gain in adulthood is associated with low‐grade inflammation in late midlife. Conclusions Ponderal index at birth is associated with CRP in later life independently of adult BMI. The findings additionally suggest that preventing weight gain in early adulthood would be beneficial for inflammatory status in later life.
