Oxidative stress could help explain the relationship between childhood obesity and a
metabolically unhealthy (MU) status. Moreover, puberty could also influence this relationship,
since it entails physiological cardiometabolic changes. We aimed to evaluate plasma antioxidants
and oxidative stress biomarkers in MU and metabolically healthy (MH) prepubertal and pubertal
children and their associations with pro-inflammatory and endothelial damage biomarkers, taking
puberty into account. A total of 1444 Spanish children aged 3–17 years (48.9% males, 66% prepubertal,
47.1% with obesity) were recruited. Blood pressure, anthropometric and biochemical parameters
were measured, and children were categorized as having a MU or MH status according to risk factors.
Retinol, carotenes, tocopherols, total antioxidant capacity (TAC), oxidized low-density lipoprotein
and selected pro-inflammatory and endothelial damage biomarkers were analyzed. General linear
models adjusted for age, sex, recruitment center and body mass index, partial correlations and
stepwise linear regressions were performed. Lower carotenes and tocopherols levels were found in
MU than in MH children. Plasma TAC was lower in prepubertal and higher in pubertal children with
obesity compared to normal-weight children. Antioxidants and oxidative stress biomarkers showed
novel associations with several pro-inflammatory and endothelial damage biomarkers, with pubertal
differences, supporting the importance of considering both the antioxidant and oxidative stress status
and puberty in the prevention of metabolic diseases in childhood.
