BackgroundSkin-derived advanced glycation end products (sAGEs) have been associated with cardiovascular (CV) risk and mortality in adults. We hypothesize that cardiorespiratory fitness (CRF), body mass index (BMI) and vascular health are associated with development of sAGEs during childhood.MethodsIn our prospective cohort study, 1171 children aged 6–8 years were screened for sAGEs, BMI, retinal arteriolar diameters (CRAE) and pulse wave velocity (PWV), using standardized procedures. To determine CRF a 20 m shuttle run was performed. After four 4 years, all parameters were assessed in 675 children using the same protocols.ResultsHigher initial CRF levels were significantly associated with lower sAGEs (β [95 CI] −0.02 [−0.03 to −0.002] au, p = 0.022) levels at follow-up, although they showed a greater change from baseline to follow-up (β [95 CI] 0.02 [0.002 to 0.03] au, p = 0.027). Moreover, individuals with higher sAGEs at baseline showed narrower CRAE (β [95% CI] −5.42 [−8.76 to −2.08] μm, p = 0.001) at follow-up and showed a greater change in CRAE (β [95% CI] −3.99 [−7.03 to −0.96] μm, p = 0.010) from baseline to follow-up.ConclusionExercise and higher CRF may help mitigate the formation of AGEs during childhood, thereby reducing the risk for development of CV disease associated with AGEs-induced damage. Preventive strategies may need to target CRF early in life to achieve improvement of CV risk factors and may counteract the development of CV disease later in life.
